[@fnorgen]

@@Kholaslittlespot1 Don't bother unless you are really enthusiastic about overclocking. I once spent over a month fine tuning my memory timings and voltage to stabilize a better overclock. The whole time it was always on the verge of being stable, but it took forever to find just the right combination of values to actually make it stable. It was a maddening gauntlet of tweaking, testing and analysing seemingly paradoxical results! All for a 1% performance gain in certain memory intensive applications.

[@Zarcondeegrissom]

don't worry, as soon as it's all sorted out, DDR5 will invert-flip-randomize it all around again so it's like trying to navigate 11 dimensional M-theory, lol. And if you think that's confusing, wait till "constructor theory" gets involved with the timings set by the CPU, lol.

[@Kholaslittlespot1]

Yeah I could really do with actually knowing what my secondary timings should be. Right now it feels like I'm stabbing in the dark a bit.

[@KillaBitz]

@@Kholaslittlespot1 It's really simple you just pick a random number then double it then roll a dice and add the two numbers together then divide by Pi. This woks for most of the settings except the ones that need to be double some other setting and should probably not exist since they are just a multiple of something else. Then there is that one that is like how long should I hold data before the capacitance drops and it's like.... You tell me. If for some reason you ever figure all this out your probably wrong since you likely didn't guess how much resistance the memory traces had so all your stability testing was skewed by that. Once your done testing it all you get to enjoy an OS that has been corrupted by unstable RAM for the past month a bluescreened into a dribbling mess so you won't be able to tell if you ever actually got it stable. Then the first hint of HandBrake or any other intensive task will likely bring the whole stack of cards tumbling down until you give up and pick an JDEC or JDEC like speed and decide that having a working machine is more important than worrying about a couple of %

[@mhnoni]

It's not XMP fault or the MB, these manufactures are just trying to hit high numbers to sell the same RAM for a higher price and to avoid instability since their chip can't handle lower latency. MB should set the timing based on the XMB and not based on MB data since RAM manufactures should give the correct XMP number.

[@AshenTechDotCom]

they dont want to do proper binning so they use timings looser then needed for the majority of sticks, to ensure even the worst ones will still work at rated xmp... i use to be friends with a guy, we would buy tray ram, would use multi boards to test ram and dial in a proper spd for higher then rated clocks and flash it to the spd on the sticks, resell on ebay and locally... never had a single return for ram not meeting spec or being flawed out of the box.. mostly had people comiong back wanting more of the same exact stuff to match with what they already got... what i found was that kits rated at jdec and kits rated at the best speeds possible, were almost always just binned sticks, and often more then half a tray would work 100% flawless at the xmp dialed on for the tpp speeds sold... we even sold some ram at higher then any official ram manufacturer was selling them flashed, we dumped the 2 lowest jdec specs from the spd and added 2 more... one that was max speed for what companies were selling then one i dialed in, around 2 perf tiers higher, out of a tray we only got around 25% that would test out flaweless at those specs but... omg did they sell... zero returns... more then a few people upset we didnt have any more and couldnt find trays of ram to buy of that type at the time...(years later he and his bro got ram when the stuff was being dumped by corporations dirt cheap and binned a bunch more and made a much higher profit due to the boom in retro pc building...) we had some fun back then... honestly.. i would like to see better auto-training for set speeds.. i have seen it get better but.. i have also seen a couple gems of boards that if you set the ram to a specific clock, the board would reboot and try dif timings till it could post and boot to windows successfully, from there you had to loosen/tighten things till you got it dialed in.. but.. gods damn thats a nice feature.... once had a buddies system take over 45min to dial itself in but.. 3hrs later we had found the "sweet spot" for the ram, and written down the key timings(both primary and sub timings we tweaked).. its crazy how big a deal even 2ns can make.. from unstable to 100% solid for over a week of leaving p95 blend running using 785% of the system ram(he forgot it running when he went on a work trip and.. nobody goes into his basement office without him there or telling them to.. so.. yeah..

[@wj5313]

Sorry if it was mentioned in comments already, but it helped me check what’s actually in my XMP profile (using Thaiphoon) and what is actually applied. My motherboard only applies the primaries. So checking the full XMP profile TFAW was like 44, so I ignored it (went for 16), but its tRC and TRRDS/L were lower than what my motherboard applied. So I just put in what was in the XMP and my Linpack results went up by 6-7% right off the bat. Good option if you don’t want to spend a lot of time on tweaking your ram :)

[@AthosRac]

Amazing that a company which is manufacturing sticks can be so incompetent. RRDS/RRDL/FAW are by far the most impactful DRAM timings these days and those settings are way worse than JEDEC spec.

[@zacharytaylor8523]

It doesn't help that most of the manufacturers who make DIMMs are not the people who make the actual memory.

There is only one company you can say sells both high speed kits and is a DRAM fabricator, that being Micron

[@IK4MS]

It's not being incompetent, it's marketing.

[@nickpowell7432]

The memory manufacturer can only program in so many timings into the extra spd space there’s not space for every timing. Everything else is up to motherboard manufacturers to optimize xmp/auto timings for every kit out there. Would be cool if all the best timings could be saved in the spd eprom.

[@AerynGaming]

@@nickpowell7432 Yeah for sure, would make stuff less likely to work in one click though due to board, BIOS and IMC differences. What is unforgiveable is explicitly programming a timing which makes the RAM perform worse than JEDEC.

[@jannegrey593]

I had this issue with my Corsair sticks. They are supposed to be 3600, but performance decreased from 2933 (IIRC). And I'm not good enough at Memory OC to do more than little tinkering with timings. Then again 3200 profile run very well (better than 2933) and I did some further very light OC on that and it is stable. I guess it is more of an issue since I have 4 sticks (I didn't have enough money so I was buying 2x4GB 3 months apart).

I'm not massively au fait with DRAM tweaking (just XMP them these days), but I'm familiar enough with the ranges to expect from cursory checks with CPU-z that my eyebrows would go up if I saw numbers like those. I'd guess that kits with XMP speeds of 3600, 3200 or even slower from other makers would also clock to 4800MHz with those timings, so these are basically not what they're touted/adertised as and a complete con.

[@adnelortiz]

Trashing the timings to relax the setting enhances the stability of the module. The manufacturer wants that because that means more kits sold, not returned nor RMA'ed because of stability issues. It's a move to ensure profits, screwing the end user in the process since most just bother to use XMP only.

hmm question, so ive lowered all my timing pretty much as much as possible and ran memtest for 24hours and prime95 for 12hours no crashed or errors, and i used aida, cinebench and timespy to check performance to make sure the timings increased performance along the way. But my question is can a timing ever be to low, i have some timings that i was able to get down to 1 without encountering errors, will that make my memory degrade quicker or something possibly is there any risk to that at all?

Which timings my dude? Depending on the ram, some timings can go down to 1 without problems. You can tell because some are set to 1 when left in AUTO

Similar happened when my PC can't boot, on my old ddr3 2400mhz 16gb kit with XMP enabled. It took me more than weeks, to found the problem. It was the secondary timing won't match something with the motherboard. Checked the jdec in CPUZ, AIDA64, I tried to match all timings table in softwares. Then, lucky I tried lowered the TRRD to 7 and CWL to 12, and then boom! the PC booted instantly with xmp 2400mhz in the table software shows TRRD = 8 , CWL =13 for 2400mhz xmp, so weird.

Constantly running into conflicting information, or behavior i can't really reproduce on my system doesn't help either. Now i see even some manufacturers don't know what they are doing either, many just seem to loosen the timings, until the memory just doesn't crash at a specific speed on whatever awkward configuration they test it on, programm this into the xmp and call it a day.

You need to stress test. XMP is an overclocking profile. People buy xmp kits at high frequencies but most of the time it takes a lot of vccsa voltage to get stable. With Ryzen running 1:1 with RAM the IF can become unstable, also IMC. With Intel like the 10900k more VCCIO and VCCSA can be needed. As both the IMC and the cache connection are affected. Just because the system feels more stable, does not mean the RAM is not erroring randomly. You wont know until you test. I have tested the RAM with the 10900k with HCI/memtest etc and past (4000MT/s C15 Dual Rank 4 x DIMMs). Then errored in large prime95 ffts.

What motherboard are you using? Is that RAM on their QVL? Being it fails to POST I am wondering on compatibility. May not hurt to check your UEFI version on your MB too

[@SacUnDruz]

@@Frizzy9000 Haven't checked up that yet, running a X570 Dark Hero from Asus, got it in June and installed newest UEFI back then, right before I installed any OS's... Gonna check these suggestions up could be one of the reasons...

[@ghoulbuster1]

Try to slowly raise the ram Frequency from default, that gives you a rough idea if the cpu can handle it because the mobo will set really loose timings to try to boot.

Takk!

[@tfwpky5020]

If my 5800x can run at 2000flck, is it worth trying to push my 3800 CL14 kit to 4000mhz

[@nanielwolf5768]

yes if you can keep the timings or just check and compare performance

[@jordibt1789]

Kudos for the thumbnail, it's lowkey amazing

[@TheOneGhost12]

Can I hire you to do timing on my pc ?

[@OCDyno]

If you really wanted to make a fair comparison force 2666 to run in G2 as well

[@jjtb7300]

Nice

[@Lukiel666]

Love these videos. But I have to admit, probably 90% of computer builders don't go beyond looking at rated specs. More than half probably don't go beyond whether it has RGB.

This is my problem that I am searching for 2 years of lag in games also my ram is gskill royal xmp 4000 cl17 dual kit xmp works really bad on my aourus z390 master!At first it works xmp on and good to go but after a while I realize massive delays lags everywhere I can't figure out what the hack I spend tons of money change components but not ram ! Than I change the timing manually as in this video after 2 years problem solved.

[@sergiokaminotanjo]

l cant stop getting surprized every time l watch a video where the latest most expensive piece or top tier hardware has the same issues l have with my old shitty low end PC xD

[@Gamingtechgg]

my ram just died feels amazing :D, instead of having 16gb now it is 64gb :D

[@JuIzNoGoud]

SO THATS WHY MY GAMES ARE STUTTERING AND ARE SHIT ON XMP ON AND SMOOTH ON XMP OFF? fuck man...

[@tarfeef_4268]

great, now I can't trust XMP anymore :( setting up new systems just got a whole lot more tedious

[@jaydude25]

I would not worry too much, in most cases you will only notice a difference in benchmarks unless your really looking for it :)

[@Scheater1337]

XMP imo is just for time-saving anyways. If you are on the high-end, XMP is kinda pointless because you wanna manually set that stuff anyways (else: why bother paying that much money?). And on the lower end / budget range, you are just wasting money paying for an XMP profile. I mean, do you really wanna pay 50 bucks more on to get a higher frequency XMP-profile for the same kit/die? Or would it be better to just buy the identical hardware with different XMP (of a potentially different bin, if you are unlucky) and manually set those numbers?

[@OCDyno]

The performance loss if more from Gear 2 then XMP, if you're on zen2+ make sure FCLK/UCLK/MCLK are synced, and run gear 1 on RKL upto 3733- ish

[@sldkjh]

I have a 3200 kit that reduces the FCLK to 1600 to run synchronous... It underclocks the infinity fabric. I had to manually set it to 4000 and 2000 and add some voltage here and there.

[@Goldenhordemilo]

my tRFC is 420

[@BITCOIlN]

This memory gen seems disappointing so far though the same was probably said about DDR4 launch as well.

[@hobomisanthropus2414]

This is the case for my Gskill Trident Z (CL14 Samsung B) The tRFC is set to something insane like 500+ with XMP enabled. AMD Ryzen 5900X on an X470 Board (This issue was also present when I was using a 2700X on the same Board)

[@AerynGaming]

"The tRFC is set to something insane like 500+ with XMP enabled." That's because it's required to operate properly at ~95c. Lower RFC's only work if you keep the memory cool, which people aren't guaranteed to do. RFC will only affect performance by a handful of %. RRDS/RRDL/FAW can half or double it.

[@IIMANIXII]

Mine just crashes often - it runs @ 3200 could be on it gaming for the day then next day bluescreens on startup - or like just now its fine all day then I go on KZbin and Ads are showing with Adblock on -wtf- so disable it - refresh - enable - BSOD - I find using my browser often causes BSOD when overclocking my Ram not sure why, that's your area of expertise I guess. . . Hyper X Predator 3200 - MSI X470 M7AC Ryzen2700X

[@jeeroylenkins3081]

I've come to the conclusion that XMP is pretty much ass and it's better to have disabled, unless you get very lucky.

[@franklogrim8510]

damn

[@jthang7]

I paid for XMP so I'm going to use all the XMP? Uh oh

[@AshenTechDotCom]

AIDA64 memory tests wont tell you much outside a general idea if you have gone too far without causing noticed instability, now, running he full bench using a quick report, the photoworxx test at least on my 7940x gives you a much better idea if your fucking shit up or making things better.. hell the overall bench can give you an idea if you made it worse or better.. why i store multi reports as i test tweaks.. very handy tool.. aida's memory bench is useful as a quick "did i make it better or worse in general?" type test but.. yeah i have found it useless beyond a vague idea.. (if you see it jump up or down alot, you get a general idea if your fucking up or not..) anyway, im having fun dialing this new system i build after my x58 board died.. (a 6c12t xeon overclocked to 4.6-4.7 is quite competitive with first gen ryzen in most games faster in several..), this x299 systems been a learning exp.. but also been more fun dialing a system in then i have had for years.... so many are so close to their limit as it is.... this.. ram and cpu have given me a shitload of fun..

[@Empyre47AT]

Isn't gear 2 worse than gear 1?

[@ActuallyHardcoreOverclocking]

4600 CL22 with JEDEC subtimings gets over 12000 points.

[@LinzJc]

Could never trust XMP before, just another factor against it and with true proof that it is scuffed and DIY should be wary about it.

[@LA-MJ]

There's nothing to wonder here. It's called marketing BS

[@19crossbone85]

I would think think that the change from gear 1 to 2 also contributes a lot to this slowdown

[@ActuallyHardcoreOverclocking]

nope it's entirely the tRRD timings.

[@sumikomei]

in fact, the before and after is gear 1 command rate 2, versus gear 2 command rate 1, so it's very close to a non-factor if memory serves correctly.

[@Arhoffs]

Some motherboards do not even run XMP profiles. I had a B450 (Asus) that failed to load up a 3200MHz XMP because of shitty VRMs.

[@KaiSoDaM]

Most b450 b350 asus are shit. B550 is kinda Good

[@lucidnonsense942]

The VRMs for the memory are so insignificant it seems rather unlikely to be the cause; are you sure you didn't have the memory controller setup wrong? Some of the early Ryzens needed the termination impedances tweaked or they wouldn't drive the memory correctly.

[@ghoulbuster1]

@@lucidnonsense942 Mind explained that out? I have a 1600 and anything higher than 2933 is unstable, nothing I did managed to fix it.

[@IK4MS]

@@ghoulbuster1 There's too much to go into, but setting RAM terminations, vSoC, and RAM impedances is pretty key to get Ryzen 1000 to go anywhere. Furthermore most termination and impedance stuff is really on a case-by-case basis so there's no real good tutorial out there. That being said you shouldn't expect much, best I managed on the platform (stable) is 3333C14. It just doesn't clock well.

[@ghoulbuster1]

@@IK4MS I see well, I wanted to go 3200 C16 on it since that's a good speed for ryzen but I spent days trying to stabilize it using really loose timings and changing everything and nothing worked. I could try again but I'm sure the problem is the cheap B350 mobo that I used.

[@ColdVenom159]

I know noobs more then likely wont know this but isnt this why we manually tune our ram lol.

[@thepatriot6966]

Those XMP sub timings are just awful.

[@eberger02]

the thing I'd like most is if they copied across timings is if they copied between BIOS updates. XMP is easy. I avoid BIOS updates it is so boring.

[@Zarcondeegrissom]

odd twist of Scott Manley, "check your sub-timings, and Overclock safe", lol.

[@Dazzxp]

Very intresting i don't really pay much interest in the subtming besides CAS RCD RP RAS , But using Thaophoon to check the sub timing really do go to shit. Teamgroup 8Pack 3200 CL14 kit. JEDEC 1200 MHz 18 16 16 39 55 26 4 6 18 3 XMP 2400 MHz 14 14 14 31 97 48 12 12

just run DISM and fix the damn corrupt OS :D
