Ryzen 7 7800X3D Undervolt & Overclock to 5403 MHz With ROG Crosshair X670E Hero | SkatterBencher #60

In today's video, I overclock the AMD Ryzen 7 7800X3D Raphael CPU up to 5400 MHz with the ASUS ROG Crosshair X670E Hero motherboard and EK custom loop water cooling.
In an ironic twist of events, I find that the direct successor of the Ryzen 7 5800X3D, this Ryzen 7 7800X3D, is the most tunable X3D processor yet. I actually genuinely enjoyed exploring multiple approaches to overclocking this X3D CPU. I hope you equally enjoy the video I've prepared for you.
All right, we have lots to cover, so let's jump straight in.

Great video, with tons of information. Recently built my first PC in over 20 years and my specific 7800X3D CPU can take a max negative curve optimization of -25 all core when running EXPO tweaked profile. -30 and greater seems to cause stability issues when benchmarking in AIDA64 Extreme.

[@Dodgerca]

How likely are these strategies to brick your cpu? Ranging from ‘pretty darn low you’ll cook your cpu’ through to ‘try at your own extreme risk’?

[@PineyJustice]

​@@Dodgerca With zen 4, even if you add + voltage to curve optimizer it will not go past the hard cutoff. Temps also will hard stop at the maximum temp. Unless you really go out of your way to disable default protections, it's going to be rather difficult to kill one. The thing that works best for zen 4 is PBO + curve optimizing, maybe eclock if you have it on your board as well, and with these it's very safe.

Thank you for this incredibly useful information. Although I cannot find eCLK configurations on my MSI b650-P WIFI, this video inspired me to increase my base clock via the FCH option available to me. I performed a moderate increase of 102, which sped up the entire system just a touch. I used Ryzen Master to understand my best cores, and used HWINFO during gaming to infer the remaining cores capability. My CPUS cores in ordered of best to worst are 2,4,1,3,5,6,8,7 so I simply set a moderate curve optimizer of -5 and -0 for top 2 cores and +5 for the remaining cores. Very stable, no WHEAs, and increased boost clock to a bit over 5200. Thank you again!

It is not, still stuck as a halo feature. For example it's not on the MSI Carbon ($480) but i heard that it's on the Ace ($700). This Asus board also costs about that much.

[@juno1597]

You're gonna blow up your CPU and MB.

[@boastyy]

I noticed your cpu soc voltage is 1.35v, with the recent news of the burning chips and expo problems, the manufacturers are hard locking the new bios versions to 1.30v max, was wondering your thoughts on this. Many users are manually setting the soc to 1.25v to be on the safe side at least until more info is known. Thanks for the video.

[@SkatterBencher]

I've been trying to follow the news about the burning up a little bit (including some of the in-depth pieces). Generally, I'm a bit annoyed with the coverage because there's still lots of speculation and jumping to conclusions. Also, I'm not a fan of calling people "lazy" without evidence. It implies intentional malfeasance. My opinion is that 100mV difference will never be the difference between "guaranteed burnout" and "absolute safety", unless there is a specific hardware design flaw causing that. Going by the physical damage, it's clear some thermal protection is failing. That could related to a dysfunctional physical sensor in the CPU or some edge-case SMU firmware bug, or something different. But what's it's not is +100mV :). I look at the BIOS voltage limitations as a way to show customers something's actively being done about it and to shift the conversation to "it's those darned overclockers again". You know ... it's not "in spec" but "out of spec" behavior. I'm not confident we'll ever know the true root cause of this issue. And, honestly, I don't really care that much about the root cause being known by the public. I'm just a bit worried that this will further detract AMD from actively investing resources to enable great overclocking experiences.

Great video. Helped me to understand what all the acronyms meant. My old 2600k was the last OC I have done. But it has been purring at 4.4ghz under an AIO for 10 years. It idles at lower temp than the 7800x3d which is also under an AIO. But seeing boost to 5150mhz using PBO2 curve at -30 and a 102mhz base clock. Ran p95 at up to 70c for 5 minutes. I am curious what I can undervolt to now to drop a few more degrees. I would like to know if I could OC just the boost. So it has a 5500mhz ceiling but idle and surfing the web only uses stock speeds for the most part.

[@steffenbachmann8346]

Hey, thank you for the great video! One question about the Bios/UEFI you used. I have the ASUS B650E Gaming and I can't turn on AI Overclocking because the "X3D chips does not support OC". Did you use a specific BIOS/UEFI, or is it limited to x670E?

[@SkatterBencher]

I'm not familiar with that error message or issue. Can you share more about it? (Ai Overclocking would be the option to enable EXPO right?)

[@steffenbachmann8346]

​@@SkatterBencher In the meantime I found a way. The menue has an other name. Unfortunately I can't set eclk to asynchron. On the asus B650E is no Option for that. It looks like the B650E has only one click generator. Or maybe it's only a bios/uefi thing and Asus don't want that option on "cheaper" chipset.

[@SkatterBencher]

To support Async Eclk you need a physical chip added to the board. So it's definitely a cost consideration to add or not add.

[@Methodical2]

Why did you choose Expo I vs Expo II? Btw, I just found your KZbin channel. I had read your OC information but did not know you had a KZbin channel. Visuals are always better than just words. Much appreciated.

[@SkatterBencher]

No particular reason why I picked EXPO I over EXPO II. I usually stick with the first option unless there's some issues

[@Methodical2]

@@SkatterBencher Ok. I asked because my research found that there are differences between the 2 and I was curious if Expo 1 was a better option.

[@matthewhaworth5935]

Maybe you've covered this in another video, but can you explain your method for determining your per core curve optimizer offsets? (Or direct me to it) or is it exactly as it seems and is just a time consuming and tedious process if you truly want to have every core at the edge? I'm curious to know your process either way.

[@SkatterBencher]

It very much is a tedious and time-consumption process. The specific tuning process depends a lot of the specific CPU, because I find that some CPUs are more sensitive to different types of workloads (SSE, AVX, etc). But my general process is pretty simple: Set negative all core curve optimizer, then check stability with Prime95 small ffts no avx for each core separately (affinity). I just check for 20sec because I'm only interested in whether it crashes immediately or not. Then, as long as all cores pass, further increase the negative curve optimizer in steps of 5. Then, when 1 core fails switch to per-core curve optimizer and back down on the one core that failed and keep going with the others. When you have a configuration that works for all cores, it's time to double check stability in various scenarios. I usually do: 1) Per-core SuperPI 32M, to check high-boost stability in light workloads 2) Prime95 small ffts all core non-avx, to check boost in non-avx heavy workload 3) Prime95 small ffts all core avx2, to check boost in avx heavy workload 4) Run all my benchmarks to ensure stability For 1, 2, and 3, you can easily spot which core is unstable and then just back down with Curve Optimizer for that core. For 4, it's more difficult, so I just back down 5 steps for all cores to build in margin.

[@matthewhaworth5935]

@@SkatterBencher Thank you so much for taking the time to detail this out. I guess I need to reinstall prime95. It's been years since I used it last and I wasn't aware you could do per core testing. SuperPI will be a huge help too because my biggest issue always seems to be high boost light workload instability with my last few builds. Thanks again. You should consider making this into a video, I can almost guarantee there are a lot of people out there that would love to have this in your usual format as a visual walkthrough for getting the most out of their CO.

Hi SkatterBencher. Love your content. Looking to perform my first overclock on 7800x3d. I know you use the EFC to monitor ambient and coolant temps. My question is, the EFC only has one header for an external temp sensor which I understand you use for coolant. So where or how do you measure the ambient room temp? I understand the EFC has a second on board sensor. Is this what you use? If so, where is the EFC mounted in the machine and is that a true ambient temp?

[@SkatterBencher]

Hi Joseph, I indeed use the ambient temperature sensor on the EFC-SB. I don't mount the fan controller anywhere since I'm always using a test bench system. But the fan controller is always in the near vicinity of the system.

Thank you kindly. I have setup an ambient temp sensor based on your advice. I’m using the Aquacomputer Quadro. I’ve tested my settings in stock form. My only other question is about Shamino’s Boost Curve tool. I understand this is an Asus tool. I have an MSI board. What tool can I use to track the average frequencies? Many thanks!

[@BinaryBX3]

I love your videos regarding undervolt and overclock! Amazing work! However I am stuck with one question I ask myself after looking at this video twice. For pure gaming purpose I assume you would go either OC Strat #1 (The easy way) OR OC Strat #3 which takes some more time to find the perfect negative curve I assume? Tyvm for any answer!

[@SkatterBencher]

You're spot on :)

@@SkatterBencher Thanl you so much for your answer.

[@BinaryBX3]

@@SkatterBencher I am in need of some advice if you can. I am pretty frustrated at this point as I run a -35 negative curve on all cores (it is actually stable both on light and heavy load) but I run into the VDDCR SOC VRM showing 1.240V - Is this safe? I updated to the very last bios firmware. I also believe that HWINFO shows wrong values because I have spikes of VDD 2.155v, SOC voltage 2.480and misc voltage 2.220

[@SkatterBencher]

VDDCR_SOC 1.24V is safe, yes. Those HWiNFO values do seem off. Maybe there's a newer version available to download?

[@BinaryBX3]

@@SkatterBencher Hey again. Yeah so I figured out those HWiNFO values only seem to have happend in combination with having AMD adrenalin overlay open at the same time which I simply forgot to disable as I completely wiped my PC after going from 5900x to 7800x3d but now all values seem to be fine and I believe I just panicked because the values were like 2x of what HWiNFO originally gave in the start which is quite concerning especially when HWiNFO was updated to last version and mobo firmware was flashed in the very beginning. Thank you for your time and reply tho!

[@robmay4294]

Thanks man. This was an awesome resource for myself as an ASUS x670e-e Gaming WIFI MOBO + 7800x3D owner. I'm a novice at overclocking and didn't have a clue about which settings to tweak in the BIOS to get a good overclock or about which overclocking method I should use. By the expert way you compared the steps to each overclock method with the results, I can easily determine method 3 (PBO Curve Optimized) is the best one for me. That seems to be my sweet spot for thermals, results, and work invested. If also have GSKILL Trident NEO 5 DDR 5 6000 with EXPO memory. I saw that you used the EXPO1 setting for the memory but I have seen others use EXPO 2 for their overclock. Can you tell me why you used EXPO1 and what the difference between the 2 is? Thanks again brother. This was a tremendous help.

Ryzen Master has a Curve Optimizing feature that will give the most performant voltage curve per core. I recommend using it because it was very accurate versus my manual tuning would have saved a lot of hours of testing.

[@kruvik]

For me, Ryzen Master has no option to optimize the curve. I heard that it's disabled for X3D CPUs. Got any ideas?

[@MMxxxM]

@SkatterBencher If a motherboard has eCLK, does that mean we can force the CPU to a fixed clock speed when gaming or does the voltage need to be fixed to stop the clock speeds from jumping up & down?

[@SkatterBencher]

Technically 7000X3D does not support manual overclocking ("OC Mode") which provides the pathway to fixed frequency and voltage. However, you can mimic this behavior as I've shown in OC Strategy #5: Manual Overclock. TLDR: you disable Precision Boost to get a fixed CPU ratio instead of constant fluctuation of clocks.

[@Cuthalu]

Those game results are a bit perplexing, one would assume there would be much higher differences. Either way, fantastic tutorial.

[@igorpajic5938]

would doing the curve optimizer in the postive direction yield better results if I dont care about the extra voltage and temps?

[@SkatterBencher]

Not in combination with Precision Boost, because the PB algorithm relies on the voltage to estimate the appropriate frequency. With positive curve optimizer, you set the voltage for a given frequency higher. So if the algorithm determines a maximum allowed voltage, the actual maximum allowed frequency will become lower.

[@Nek2]

Hi all. I have Rog Strix x670e-e gaming wifi mobo, 32 gb ddr5 6400 cl32 G.SKILL ram, ryzen 7 7800x3d. On current bios 1416 I am able to achive roughly 5335 mhz clock per core on my cpu. Using strategy #3 from this video, didn’t want to try manual core by core settings so did all at once. So my setup is also 6200 mhz, since 6400 mhz was not stable in DOCP I profile (mobo does not have EXPO for some reason, but it is esentialy same thing just different name for Asus). Precision boost overdrive - enabled, curve optimizer - all cores, negative, and i did 25 magnitude. Tried 30 did pass cinebench R23 but in idle crash, 35 magnitude crash instantly, and 25 was stable for me. I can probably go higher on some cores, and some not, but as I said, i didn’t want to do manual per core overclock. Managed to get around 3.25% (give or take) boost in performance (not counting gpu overclock) and from around 5000 mhz max core clock speed to 5335 mhz per core. Temps stable, droped i think 2-3 celsius from 88-89 to 86-87 in full load Cinebench 23. Idle startup is around 45-47, normal to heavy workload 65-75 celsius and veryhigh workload 86 celsius. Cinebench R23 score - before cpu overclock somewhere around 17400, after overclock 18051. I do not play highly intensive games, and even without OC i had enough fps in games, but did it anyway just to check the results and pass info here since there is almost none cpu overclock videos of this cpu after this fiasco with Asus and their burned up cpu and mobo. I couldn’t hit chinebench 23 scores he hit in this video, but i think that is due mobo diference (his is higer rank and have 20+2 A teamed power solution rate while mine have 18+2 , maybe clean windows 11 instalation, and some other thing, I don’t know, I am not expert, and don’t even know is that ever relevant for cpu overclock, but I have seen my cpu hit 18200 (give or take) score in Cinebench R23 when we put sistem together and did first few testings. Hope this helps someone.

[@zbrkesbris5987]

there is a smidgen of extra performance in manually tuning memory, because EXPO profiles are not good enough. Although the effect of memory tuning is greatly reduced on x3d chips, its still greater than 0.

Hi, if i use my 7800x3d with blck 102.93 i get in windows almost 5.2ghz.. should i use pbo with this method or disable? Right now i am using pbo amd eco 170w setting with a curve -10 all cores stable prime95.

[@bennern2183]

Hello! I just wondered if you plugged in your second power cable, one 8 pin and one 4 pin to the motherboard? One 8 pin can handle 150Wattage, but not over i think ?

[@MrConceito]

It most certainly can but I’d still plug in the extra 4-pin if you are able to. Less current through the 8-pin meaning less heat/power used to supply the proper voltages to the CPU itself (that is unless it only utilizes the 4-pin after the 8-pin is maxed out, I don’t know how it operates) . If you’re not overclocking it probably doesn’t matter, but if you’re on this video I’m assuming you are and would recommend plugging it in.

[@ToxicDuck92]

U have some settings, that i dont have on my B650E-F ROG. Like x3d OC and elck2. Is this a Motherboard or Bios thing? Cause my Bios is on the recent update 1408. Would like to here some nice respond. Thanks for the Vid!

[@blkshp25]

Unfortunately only ASUS 670 boards have extreme tweaker in the bios. I have the same board and opted for OC strategy #3 of the video. Not only do we gain a few frames in gaming but the CPU runs cooler by 5 degrees even at idle. Also for even more performance I applied buildzoids memory timings to the RAM. KZbin "Easy memory timings for Hynix DDR5 with Ryzen 7000" for his guide. Enjoy!

[@Uranday]

About overclocking, with the exploding CPU's, how safe is this?

[@Saretz]

So for any of us on a b650 without ECLK, we're stuck with pbo 2 curve optimizer basically, right? I'm running mine all cores -35 with RAM at 6000 IF 2033 (as per buildzoid hynix timings) and seems stable, but doesn't boost past 5050 mhz, around 82° celsius cinebench r23.

Thanks for a very comprehensive video - Just a question on the EXPO settings for your memory. I have G-skill 6000mhz RAM. You use Expo1. What is the reason why you dont use Expo2 or Expo Tweaked? Which would you recommend I use? also I see you have 6400mhz which you tune down to 6200mhz. With my 6000mhz, should I be tuning it down to 5800mhz? I thought that the sweet spot on AM5 is 6000mhz. I am very interested to hear your views on the different EXPO settings. Thanks

[@SkatterBencher]

EXPO I loads just the primary timings, frequency, and voltage. So I let the motherboard tune the other settings like secondary timings. I don't have a real preference, it's just my go to EXPO settings. In terms of performance, EXPO Tweaked > EXPO I > EXPO II, usually. But this can be different on your system and the only way to know for sure is to check yourself. As for down-tuning: the sweetspot seems to be 6000 indeed. While my kit is rated at 6400, few CPUs I've come across can actually run that stably. Hence why I downtune the frequency. With your 6000 kit, you likely don't need to downtune (unless it's somehow unstable).

[@warnerbouma5475]

[@seifenspender]

What is the difference between EXPO I vs. II vs. Tweaked? Can not find any info on the profile differences on ASUS / G.Skills websites.

[@SkatterBencher]

EXPO I loads EXPO primary timings, frequency, and voltage but lets the motherboard optimize the rest of the EXPO timings EXPO II loads the full EXPO profile, including the primary and secondary timings, frequency, and voltage. EXPO Tweaked is EXPO I, but also adjusts some non-EXPO profile timings according to the motherboard auto-rules.

Where to find this external clock in ASRock x670e board? Anyone? I did curve undervolt but can't find eckl anywhere...

[@JanisMegis]

Bingo! Thing that i was missing in ECLK OC was increasing per-core CO for failing core...Thx!!!!... I assume you can have smaller ECLK increase, and per-core CO might stay into minuses or you can have bigger ECLK and some of the cores have to move into positive CO . How do you determine max ECLK? at what point are you stopping? As CPU is voltage sensitive are you stopping at first sights that CO needs to go into positives?

[@SkatterBencher]

Great question! And the boring answer is: it all depends on your CPU :) When you're pushing ECLK and you find there's a bunch of cores that are hitting the fmax, then it makes sense to continue pushing up the eclk to get more frequency. Then start giving the worst core a positive CO. However, if there's only one or two cores hitting the fmax, then it makes sense to leave those be and use negative CO to push up the others a bit.

[@skypickle29]

@@SkatterBencher what are the signs that a particular core is hitting fmax?

[@skypickle29]

@23:29 you said to raise Eclk until unstable and then increase positive core optimizer all cores. then check individual core stability and raise CO more for unstable cores. But in your settings you only had 1 core +10 and one -5. So how many restarts did you need to get there? And if you uniformly raised CO initially(as in the slide), how did you go about deciding which cores to reduce it on?

[@justaguydoinstuff]

So I'm confused, do you choose 1 of those options? Or do I enable all three options?

[@ertai222]

You combine them. You use PBO plus curve optimizer to lower the voltages of each individual core. You can use Ryzen Master to help find each cores limit. Then you overclock your ram and tighten timings.

[@GoldenEagle0007]

which bios did you use? looks like you choose bios 1002 any reason behind it?
