"Optimizing" the i9 14900K on the MSI Pro Z690-A DDR4 with 0x129 Microcode

23:45 - I noticed the same. When I was on the edge of stability I had these symptoms: - Task manager being slow to load (sometimes it took 5s to switch between "processes" and "performance") - Scrolling through youtube comment section caused stuttering. - Dragging windows around was choppy. All these symptoms were gone when I raised the voltage by 30 mV (-120 mV to -90mV).

Thank you for doing this with an MSI board! It's much appreciated!! Applied this to my Z690 Unify and an MSI Z790I Edge, of course with some slight variances. Great results on both! Thanks again!

[@AzwraithPL]

That voltage spike at start-up is scary. Luckily MSI was setting their AC loadline to 50mOhms at default previously which would have helped curb the voltage up until now, but since I'm pretty sure the new BIOS updates just set AC_LL = DC_LL there's going to be a lot of people who updated their BIOS in the hopes of prolonging their CPU's life only to be slowly frying it every time they turn on their computer. And the scariest part is you have no way of knowing if you're affected or not unless you have an oscilloscope to hook up to your board.

[@ActuallyHardcoreOverclocking]

yeah but MSI's 0.5 mOhm ACLL literally causes some CPUs(like mine) to crash.

Im lazy, i just use intel extreme tuning app's with its Speedoptimizer 2.0 turned on at boot. If i do the same on the intel default settings profile, it goes crazy. Pushing 1.3V on all core load CB23, when it should do 1.2V. Results in lower clocks and 100C on some cores. ASUS profile it just works fine, temps 75-80C, all core voltages 1.21V on the same test.

[@rishi2504]

Thanks a ton!! Exactly what I was looking for.. Just to add - Someone posted exact impedence values of LLC levels and Lite Load AC_LL/DC_LL values for this motherboard on some forum recently. Apparently, you wanted to set 0.3ohms, which is why you selected Level 3. But Lite Load Level 3 and LLC level 3 correspond to different values, not AC_LL of 30 and 0.3 ohms respectively

[@leeloodog]

Anyway my biggest compliment to you Buildziod. Is i really appreciate you acknowledging what you might have learned from all of this in terms of what you might choose to eval in the future. Who would have thought of this at that time about all this? I think going forward it would be nice to add this analysis (voltage control) to the mix. What is the actual voltage, how is it control, does it make sense et, not just what the board can do in terms of peak, sustained power, but almost like power quality--- smoothness etc. I do kind of wish they just had a hard voltage limit. I'd just set it to 1.35. I was looking at this over the weekend, and the llc, and lite load is this complex balance. You try to stop the cpu from over shooting or dropping, and stopping it for over responding to that drop. I basically had to put this in terms of a hose and trying to fill water, and what happens when you plug the hose quickly. and all other kinds of things.

[@bauerns5er]

As a MSI User I want to thank you for your Testing and Insights. You've found out yourself that we are plagued with the limited possibilities like the for some reason not opened IA VR Voltage Limiter. May I ask you why you did leave the undervoltage protection "enabled" does it do nothing like the AVX guardband setting that I hinted you (and was wrong) on the last Video? edit: Wait a minute it IS disabled on your last Screens of the advanced Menue (Minute 38:41), but when you look at around Minute 11:17, undervoltage Protection is "enabled" (both times settings are on "Auto"). MSI things...

[@Raxiel497]

Undervolt protection just sets a floor to the voltage settings at boot. You can still set them wherever you like in the BIOS, but once its booted, software can only leave it alone or increase it. XTU requires UV protection be on (if virtualization is enabled). While I was tuning, I'd set an aggressive UV in the bios, and then bump it up a bit in windows with XTU when trying various raised multipliers, and then go back to the BIOS to commit those final values when I was happy with it.

[@Aviation_16]

Great info!! The way the CPU calculates instructions varies from one app to another too. This can be why some games work and others don’t, and even might be why some CPUs have degraded faster than others. All this should be considered when UV’ing and stability testing.

[@MrBoxershorts16]

[@lanserap3821]

Please help us to know why Ring Limit Reasons is always YES even in this video ? Is there any issue with it ? Any way to fix it ? Whether setting ring ratio and ring down bin will solve this issue ? 65w non K CPUs didn't have this issue but K series having it(checked 12400 and 14500 CPUs). Ring may be getting high voltage. Is the initial high voltage causing it ? It will be very helpful if you can add a video about this issue. A lot of people are confused about it and thinks this may be one of the reasons for degradation.

[@christianehlscheid5807]

Hello, I have the same issue, but came to the conclusion that it is just an unfortunatly named hardware limit flag. The reason it's 99% on yes even in idle is that the ringbus frequency is linked to the maximum P-core frequency minus a 5-600 Mhz offset. So it constantly "throttles" depending on the P-Core clocks, but that's how it's supposed to work. Not all these flags indicate a real issue with the system, "IA: Max Turbo limit" for example and the "RING: MAX VR Voltage, ICCMax, PL4" is one of them.

There's yet another bios released for this board, not sure what the real difference is, 8/21 version "7D25v1J" -- doesn't have beta so not sure what exactly the difference is though. edit, not sure why, but MSI has a really weird naming structure, the earlier "beta" one is listed as version 1J.1, where as the newest (listed on their site as released 8/21) shows in flash as 1J.0. "build date" is literally the same between the two in flash as well (8/15).. which is stupid to me why they would listed as that. God MSI is really starting to piss me off these days.

[@JCM45]

Good video, really helped me tune my 13700K. I'm running the DDR5 Wifi version of this board and installed the newest, non-beta BIOS they pushed on the 21st with microcode 0x129. I dont' have my own probe so I can't monitor the voltage during boot, but I was noticing some pretty high spikes on stock settings, pretty close to, or at 1.5V when running Cinebench R23, and I was thermal throttling. I have a 360m AIO sand it's mounted fine, so it wasn't that. Following your advice, I dropped the CPU Load Line down to Mode 8, anything lower than that and I was seeing performance loss, with a negative offset of 0.07 and now I'm getting better temps and a bit of a performance boost from stock. Bumping up the offset to a -0.08 also results in some performance loss too, but I may have to play with it a tad more. I think I'm dialed in quite nicely now, Cinebench R23 and R15 are only getting me spikes of 1.3V in single and multi core workloads. I've had this CPU since launch and the only issue I had with this PC since I built it at the end of 2022 was the first 4080 I got ended up being a dud and causing me all sorts of problems, but replacing it with a new one resolved everything and it's been great since. This video was very informative and did a good job explaining all the CPU Load Line stuff that I was otherwise getting confused about. Thanks!

[@Ironbunny80]

Thank you for this video. My 13900k voltages dropped dramatically following your info here.

[@doneigoreee]

Hey guys, can someone clarify something for me? Is having a Vdroop a bad thing? I'm sitting on z790 with 14900k with Intel defaults, and LLC 8 with AC80 DC110, adaptive offset of -0.12 and according to HWinfo64 under full load it sits around 1.20, in gaming avg 1.27v with peaks to 1.33v iirc. Here Buildzoid used far more flat LLC with lower AC DC which if I understand correctly leads to smaller Vdroop. On his earlier videos I'm pretty sure he didn't went as far down with those numbers. What's the benefit of doing this? Thanks in advance

[@kpm4620]

A couple of things here. First off, a lower, droopier, LLC has better voltage regulation and helps with the voltage spikes. The thing you have to worry about is at idle or when it boosts to its 1-2 core max, the voltage requests go through the roof. The other part is, why did he choose a higher, flatter, LLC and go against what he said in previous videos? Well, back when he made this video, MSI boards didn’t have the option to set a voltage limit. So, if you were using a lower LLC with no limiter, it could potentially degrade your cpu. However, with a higher LLC, voltages come way down. Yes, you’ll get spikes. But even at those peak spikes, they’ll be less than the top voltage requested with a lower LLC. So, he’s saying to do this if you can’t limit your voltages.

[@Aart-rp3ee]

Yeah i7's! thanks for the shout 😅

[@BrutalDesu]

Thanks a bunch sir

[@AzwraithPL]

If I remember correctly with these boards I believe LLC3 is 0.10 mOhms and Lite Load 3 is 0.15 mOhms on the AC_LL so you'd actually want to set your LLC to 4 if you wanted it to match your AC_LL at Lite Load 3. Although I think the Lite Load DC_LL is set to 80 mOhms from modes 12 to 2 so your power readings will probably also be thrown off doing it this way. Personally I just suggest manually setting your AC and DC loadlines rather than using the Lite Load presets.

[@sp00n]

For my MSI Z790 board, Lite Mode 3 is AC 10 (0.10 mOhm) & DC 110 (1.10 mOhm). Z690 may be different of course.

[@ActuallyHardcoreOverclocking]

LLC Mode3 with 0.1 ACLL sees a slight performance regression.

[@AzwraithPL]

@@ActuallyHardcoreOverclocking Actually it seems like MSI Lite Loads have different impedances depending on whether CEP is enabled or disabled so what I said wouldn't necessarily apply in your config.

[@Raxiel497]

MSI annoyed me with that 'automatic extreme settings' thing too. I have a 13600KF, so thermal throttling was never really an issue, but it did spend a lot of time throttling due to the new 200A current limit in the intel defaults. Undervolting did eliminate that without having to go too far. Then I wanted to raise the clocks from the stock 5.1/3.9 P/E to 5.4/4.3 that I knew it would do at that voltage, but MSI insisted on switching the power profile when I did so. As far as I can tell, the only thing it changes is setting PL1/2 and max current to unlimited and I was able to change it back, but still annoying. With the overclock It still hits the current limit (up to 220A) in all core, but performance is no worse than stock and its better in general use applications that don't throw 20 threads at it (the 3d mark CPU test even showed a small increase in 16 thread)

[@fabiogiuliani5393]

In my case on MSI mb if I only selected "intel default profile" I lost 50% points in Cinebench r23 multicore... So I swapped back on MSI profile and do undervolt, but I don't know if I'm doing well or not now.

[@MrHytin]

Mode 3 on loadline and mode 3 on lite loadline,ends up in 100/1100 in ac/dc but do not trigger CEP, how come

[@BrandynMauro]

Why use adaptive+offset instead of just offset? I thought adaptive+offset would only offset voltages at high load, hence a single core workload would still be able to request a high voltage.

[@cam_bro]

Looking forward to your asus video. Still a bit confused over LLC and its relation with AC / DC load line. I miss the simplicity of overclocking in the old days (athlon xp / p3). Tweak the vcore, increase the cpu multipler, pass prime95 and you were golden 😂

[@usrname1y]

I just have one question, why are you not using the same or similar LLC settings like switching frequency etc. that you used in the MSI Pro Z690-A voltage regulation and VRM settings video.

[@tigros999]

[@rtyzxc]

The best way to overclock a GPU on MSI afterburner is to make a custom curve where you use the highest offset at the high frequencies that are needed at heavy workload, and gradually lower and no offset at lower frequencies. With the curve you can also cap the frequency at a level you know isn't stable, but that the GPU might opportunistically shoot into for a split second with erratic loads, but isn't practically useful. Can't believe we still don't have this for CPUs, it would be a huge selling point for a motherboard.

There is no vcore voltage, IA ac and ia DC are in different places, happy I found them, load line has different settings and something with synching vrm voltage with ac DC loadline, an there are level 1-3 loadline and then also load line 1 to 8, I took 5 bacause I counted from your video the options on gigabyte and then used it in number form. but then there is vrm voltage offset, svid voltage ofset, and the v/f curve, but no general v/f offset voltage, only per ratio offset voltage, and there is no dynamic voltage offset and I don't know what to change, I have some crashes but don't know the reason, both with vrm offset and svid offset, and the v/f curve is more confusing, because I don't want to do something wrong, I don't know if I can kill my cpu with undervolting and I don't know how to adjust ratio and tvb oc, and things like that with Intel default, because if I enable the 2 best cores to 60, in tvb it says all cores have a 60 ratio, even with all core, and then I can't fine tune it really, and what does xtu do, can I use xtu for things like that and what does xtu affect? Asus calls things different and there are some things completely missing (generally v/f offset, dynamic offset, vcores) and also I don't know what does what (svid offset and vrm offset and things like that, cpu svid, cpu power request, and so on) and a video on a asus board z790 would be very helpful if you could do that, because there are no explanations manuals for the bios and no guides with "translations" to other board naming schemes, and so I am at a los and a bit scared trying it on my own without a real guide on it.

Hi BuildZoid, my interaction is generally very limited in the comments, but I have a concern. I have an MSI Z790 Edge WIFI DDR4 with an Intel I7 13700K, since I built it I have never had temperature problems, game or program crashes, BSOD with synthetic benchmarks, CPU stress, nothing. Should I do the update anyway? However, I have my CPU with certain configurations, such as all P-cores at 5.5ghz and E-cores at 4.3Ghz with 1.27v, LLC lvl 3 and XMP at 3866mhz.

[@_MartyMan_]

Thanks! With latest BIOS, i tried your method on my 13700KF and it works perfectly. Also i went with mode 2 on both Loadline and Lite Load, with better scores on CB23. Is it safe to do? Could you suggest how to achieve a mild OC?

[@zeddy6198]

Hello. I am using 14900kf and msi z690 force Intel default profile I'v done negative offset to 0.100 and lite load to 3 as you mentioned. I am getting 36600 in cinebench 23, and i think it is rather low. Is it? Should i rise power limit a bit, or do something else? Thank you

[@0x1stvan]

Wait, i can just undervolt my cpu using the IA VR voltage limit on gigabyte board, do i need to set anything else?

[@justdointhisforthegames]

on the new BIOS Intel defaults, my MSI motherboard must have been doing what yours is doing, because it would hit in excess of 1.55v on windows startup, according to HWinfo64. (don't have an oscilloscope, so I can't know for sure, I guess.) Great video, as always.

I did the 150mv undervolt offset on my 13900K with MSI Z790 Edge WIFI DDR4, R15/R32 Score are now 6123/38409 up from about 5500/36000. The CPU isn't hitting TjMAX with a temp of 103C anymore, it's running at about 1.200v with a max temp of 93C. I think it needs repasting, but I'll be going with a thermal pad soon. Anyway, I'll change the undervolt offset to 140/130/120mv, etc. if I find any instability. Thanks for the video!

[@sp00n]

Is there a difference between "Offset Mode" and "Adaptive + Offset Mode" in the CPU Core Voltage Mode? As far as I have understood it so far, when you leave the Core Voltage at Auto with Adaptive, it's the same? And if your set a voltage there, it will only apply if the CPU boosts above X (5.7 Ghz?), and the entered voltage value is above (not below) the entry in the internal VID table of the highest VF point entry (also 5.7Ghz?)? There are so many entries on MSI boards for the Vcore setting for Intel that it's really confusing.

[@Keaweahe]

Adaptive makes the vid request match the vcore for me, so i think its better. If i just use offset, then i end up with 2 different values. Example for offset is, the vid requests 1.4v and my vcore is 1.2. if i use adaptive they end up being the same number. Not sure if theres anything wrong with using regular offset though.

[@sp00n]

@@Keaweahe Did you use both times use LLC Auto and AC/DC Auto values? I'll have to check again, but I don't think Adaptive + Offset does automagically set the correct AC/DC loadline for any selected LLC value.

Buildzoid's just recommending keeping it on because that's what it says in the Intel recommendations. Whether or not turning it off will actually have any meaningful consequences none can say because the documentation on it is so sparse.

What’s worse for degradation, high voltage or high current?

[@ActuallyHardcoreOverclocking]

depends

[@vincentschumann937]

theres a video on this channel about degradation, should explain why its not that simple

[@Savigo.]

For voltage, as long as you don't cross certain threshold it won't degrade anything. The problem is, we don't know for sure what the threshold is and you also have to accont transient spikes and normal distribution of voltage across all the electrons (for example if the osciloscope shows 1,3V, say 1/10^9 of all the electrons could still carry more than 1,32V and another 1/10^9 below 1,28V - numbers out of my ass, but you get the idea). Current always causes electromigration, but it's usually so slow that it's not a problem. Well, unless your CPU is constantly pulling 200+A with 300A spikes, which 13th and 14th gen can certainly do.

[@imqqmi]

I wonder what the actual impact is of an overshoot voltage of 1.59V. what percentile is over/at that voltage? If it's only 50us every second or so that can't really cause heat damage. Unless it rises above clamping voltage like static electricity I don't see how this can degrade the CPU.

[@trixniisama]

You know that heat isn't the only point of failure of electronic devices right? Over-voltage itself can be damaging.

[@imqqmi]

@@trixniisama yeah I know about static voltage degrading barriers/junctions in MOSFETs and capacitors but at such low voltages is that still a thing?

[@trixniisama]

@@imqqmi It's what damages the ring, so most definitely. All electronics have operating values, a specification, and if you go out of spec, well the behavior cannot be controlled anymore.

[@imqqmi]

@@trixniisama According to the datasheet Vcore max is 1.72V. max overshoot is 10% for 500us at TDP. An overshoot of 1.59V for 50us is well within that range and I believe his CPU is around 70⁰C under load but not sure he hits TDP limit. Of course if the chips are faulty the specs can't be trusted. They state at TDP and a time limit, suggesting that over voltage main concern is thermal damage. What other failure modes could there be at or below 1.72 + 10% is 1.892V?

[@trixniisama]

@@imqqmi I mean, what do you want me to tell you? Concerns about too much voltages have been lasting for years. The fact that Intel does not actually have a proper specification is what led to the recent motherboard debacle. Now they've published guidelines but anyone knows that pushing 1.5V is already insane, let alone 1.7V! This "specification" was delusional to begin with. Board partners are trying to reduce voltage and not TDP or thermal limits for a reason. Temperature hasn't been a concern in modern CPUs for a while.

[@antagonist24.52]

If you could also probe into the behavior when TVB voltage optimization (enabled by default) is disabled, that would be great. Even if AC_LL has the same value, there is a difference in the voltage the CPU gets when it is enabled and when it is not.

[@Cormy1]

Hey Buildzoid, can I ask you a favour? Can you do a "quick" comparison between the Raptor Lake voltage behaviours and Alder Lake? To demonstrate how even if both are set to the same voltages (and clocks?), Raptor Lake has higher excursions due to the overshoot/over aggressive voltage drop compensation? Preferably a 13600K or some other lower-clocked/power Raptor Lake CPU that's more comparable to Alder Lake? Like a 13700 vs 12900K? Just enough to see the boot behaviour + single-threaded R15. A default/stock VF curve comparison would be cool too.

I had a weird bug on my MSI board, if I switch to the 4096W power settings, it basically massively reduces the performance to like 16,000 R23 points, you can even switch the power profile back to Intel Default Settings and it doesn't register it as the default profile, it stays stuck bugged till you clear CMOS. Beta BIOS' are so much fun!

[@EddieGD21]

Hi BuildZoid, if you haven't already done so, can you test the MSI 0x129 BIOS to see if it disables the 1.55V limiter when you leave (or get kicked out of) Intel Defaults. MSI tech support refuses to give any guidance on this matter because the people we spoke with either didn't understand the question or didn't know the answer.

[@DimbleWally]

Why don't you test it yourself? Do you have an MSI motherboard and a 14900k?

[@ActuallyHardcoreOverclocking]

I did a quick check and both of the MSI profiles seem to have the 1.55V limit in place. However the unlimited profile disables CEP and drops the AC loadline to 0.5 which with my CPU destabilizes cinebench R15(so that's something to keep in mind if the unlimited profile is unstable for you). But with MSI's BIOS you can still change the ICCMAX and power limits even with the intel defaults enabled.

What values does CEP actually compare to decide if it should trigger or not? From what I understand (excuse any blatant ignorance please) there is lets call it default VID, Which is what is written on the cpu vid table, the AC LL adjusted VID, which is what it actually requests, the VID readout, which is the AC adjusted VID further adjusted by DC LL (?? or original VID djusted by DC LL???) and the vcore. So... what does CEP compare to what? Like, if the vcore matches VID in HWinfo does that mean the CEP is happy? or is it going to still do some -magic- weird math and still freak out because oh no mercury is in retrograde today and also vid readout doesn't match vcore divided by AC LL multiplied by the square root of current or whatever tf? Really sorry if you already covered this and I missed it.

The AsRock Z790 boards have a hard limit of 100mv negative offset. Also they don’t have a setting to limit the voltage vid request. Not that I can find anyway.

You can undervolt further by using OC Tweaker/FIVR configuration instead. Set core voltage mode to adaptive, VF offset mode to legacy, VF configuration scope to All-core. Then under core voltage offset you can enter the amount of undervolting. Hope this helps.
