As for QVL, while it helps if the memory is tested, however, pretty much all** Zen4 CPU will do 6200. There's also an option for 4x16 with two 2x16 kits as they don't technically make 4x16. They should have similar maybe even slightly better performance when overclocked than 32Gb kits, as DDR5 presently has little to no benefit from dual rank memory.

Nice! You can very likely push further. This is where I settled. I could do 6400 with 2200 FCLK but it required too much voltage to justify minimal gain. This is fine for me for 24/7. Went from low 60000 read/write and 70ms latency on EXPO to that. Now just trying to lower voltages as much as I can.

You're likely GPU bound for which CPU/Mt isn't going to do much. You could try drop settings until you're CPU bound then try same settings in non-MT build and compare performance.

Windows is integrating RGB control sometime soon-ish. It's already in the preview builds and should hopefully eliminate the trash that is RGB control.

Dang! That is a pretty hefty uplift.

Yeah, I have a 2x32Gb Gskill 6000 32-38-38-38-96 kit I'm using. I started with his settings and now working from there. Below are two screenshots, one stock XMP and the other with BZ much improved timings. Overnight stable on TestMem5 anat777 extreme. Last one is my current settings.

I took what my card was max boosting to stock, which was around 2745 then looked at where it typically settled, which was 2535/2545. I then adjusted the curve so that at +200Mhz which would put me at my max stock boost clock, would max out at 950mV. You have to play with the voltage curve and boost speed. I started at 975 and after testing it was stable, I tried 950. After determined it was stable, I tried 925mV it was stable but would not stay at 2745 and would boost lower. So I left it at 950mv and +200Mhz(2745 effective). Memory +1000 it's a shot in the dark, but was stable; honestly, could probably go further. My 4090 is on custom water loop with load temps at around 47C, not sure how much of a difference that makes to the boost algorithm. My card allows for 133% Power Limit and will boost to between 3000-3100, but also draws a refrigerator-equivalent amount of power for a marginal gain in actual performance. I got higher 3DMark scores, but in game it translated into 3-5 FPS at best.

Ah, I see. I'm no specialist by any stretch either, but that makes sense in the context of staying under PSU limits. Unfortunately I don't have the Mirage module.

Some good discussion on the scheduling "hurdles" of the dual CCD X3D CPUs.

Honestly, I'm not entirely sure what point you were trying to get across. There was a lot of writing, but nothing of apparent substance that's not already commonly understood by most. A, M, B die are all just revisions and not some alphabet magic that gives memory speed. Contrary to your belief, people do use Hynix A (AFR) die based DDR4 with Zen3 as it is able to hit 3600, but the timings aren't as tight as Samsung. Samsung's revision (B in this case) is the best chip for DDR4 (Zen3), followed by Samsung E. Die, followed by Hynix CRJ and AFR. In DDR5, Samsung is inferior to Hynix. I'm not privy to AMDs design decision making, neither are you, not sure if either of us could speak to what drove the design of Zen4. Zen 4 was designed around the same time as Alder Lake and Raptor Lake, so the same RAM was available to both, yet Intel MC can handle higher speeds.... Food for thought. And yes, when lower latency DDR5 is available (not sure what makes you think it will be able to get down as low as CL14 as there's no guarantee), it will be better than what's available now... Think that's pretty obvious. At the end of the day, the existence (or lack there of) of what you call "B. Die equivalent" is irrelevant. Equivelant Zen4 with DDR5 6000 outperforms Zen3 on DDR4 3600 CL14. DDR4 is old tech at this point. It's not going to get any better. Is it still relevant for those on DDR4 systems? Absolutely and one should get the best for those systems. DDR4 is at the end of its life cycle...DDR5 Zen4 and RL performance is already (right now, today!) better than what's available on DDR4...Time to join us in 2023 and let DDR4 go.

Any reason to lower power limit on top of a power curve, seems redundant? Reason I ask, and I'll have to verify when I get home to make sure I'm not talking out of my 3rd point of contact, if I recall I had better performance with power curve only VS OC, or power limit. Current power curve is 950mv +200mhz (~2745mhz core) +1000 on Vram. Same or better performance at almost 100w less stays boosted to 2745 almost indefinitely, load Temps about 47C on a custom loop. Could you share the track file to try?

I've given up trying to explain this to some people mostly just reply to their nonsense to correct misinformation and keep it from being propagated.

VR recordings are difficult to judge smoothness sometimes due to recording jitter which isn't noticeable in the headset but looks terrible on a 2D recording. That being said, I haven't seen the video so I don't know if it's a stuttery mess or just normal jitter from VR to 2D recording.

Should be an awesome build. One thing to take care of is RAM, being 6400mt/s, you may have to dial it down to 6000 or 6200 as very few memory controllers on Zen4 can reliably hit 6400. Also, the XMP timings will likely be VERY conservative/loose. Take a look at this video, your kit is likely Hynix A die (maybe M.die) so you should have no problems copying secondary, tertiary and Tras timings for a significant boost. Note: only do that after you establish that the system works as it should stock config (minus dialing down the RAM from 6400 to 6000). As for 7950X3D vs 7900X3D, I would personally would have opted for the 7950X3D simply because thermal headroom will be insignificantly different due to the IHS (thicc) and you still retain the same scheduling "obstacles" but you lose out on 2 extra cores for both v-cached and non cached CCDs, base clock is irrelevant as you looking to boost as much as possible and 7950 will boost higher; 7950X3D is extremely efficient with 120w tdp. $100 difference in price is arguably negligible at that point as well. All that being said, I don't think you'll be disappointed with the 7900X3D and should be great build when done. Just make sure you update your BIOS and chipset drivers to the latest offering as you incur a significant performance penalty otherwise.

That is the case with me. It's all about smoothness. I can't play without reprojection. With turbo mode and my detail settings I'm usually 55-65fps. With reprojection it's pretty much constantly locked at 45. I will take reprojection at 45fps over no reprojection at 55-60 any day... Because it's completely immersion breaking and unpleasant. With turbo mode where I hit 90+ FPS it's super smooth. As soon as it drops below 80s I start to really notice it. So unless I can maintain 90fps, reprojection staying on for me.

Is that a location thing? Because there are plenty of CL30 and CL32 64GB kits available, at least here in the US. Also depending on what CL40 RAM is, Kingston for example, could actually be Hynix M.die and should be able to hit CL32, and more importantly, tighten up secondary and tertiary timings for a significant boost in performance.

You are right there is no CL16 DDR5. What you can't seem to understand that doesn't have as much an impact as you think. Because zen4 X3D and non X3D on DDR5 6000 CL 32/30 are spanking their Zen3 counterparts on DDR4 with CL16/14 RAM due to sheer bandwith. What is equivent to B. Die anyway? Hynix A/M dies run circles around Samsung Bdie DDR4 in bandwith.

Should answer some questions on reliance on RAM of the X3D chips. Also some suggested that RAM is limited to DDR5 3600 in 4x stick config. This isn't accurate, at least not in practice. 4x16Gb (these are single rank) works just fine at 6000 mt/s. As for 7900X3D, further suggests that it mostly exists to use up rejected dies that couldn't have 8 cores.

I love Wendell, he's very knowledgeable and is able to impart that knowledge effectively. Nothing flashy, just good solid info delivered by someone who actually knows how things work.

I can't comment on the WH as I never had one. But I have two VKB Gunfighters, latest being the Ultimate. I love them both of them. Very robust build with tons of customization between cams, spacers and springs and tons of buttons and interchangeable ministicks and 5 way switches. Have absolutely nothing but good things to say about the product. I even recently purchased their pedals which are fantastic, especially for rotary. What sucks is their availability, as you have found out. I bought my original Gunfighter at launch after which point they were unavailable for several months. Same thing with the ultimate, where full kits were available but sticks only were not. Shipping was reasonable and quick when they are in stock. Are you checking their NA store or International?

Indeed.

Yeah, honestly, I can't really find a justification for 7900X3D's existence other than to eat up reject dies that only have 6 good cores. At this point folks are either getting a 7800X3D for pure gaming or they're getting a 7950X3D for heavier workloads and having gaming vroom...the price delta between the two high end SKUs aren't doing 7900X3D any favors.

I don't know your specific situation and needs so it's hard to make a call. The question is, ARE you going to get "much of the same performance" though, especially with DDR4 VS DDR5. I suppose that would also depend on what you consider similar performance (ie. Is it within 5% or are you considering 10-15% to be close enough). Are you looking to do an incremental upgrade or a new build that lasts next 3-4 years? Budget? Other games or productivity needs?

If it's on the 20-25% side of the scale like Tomb Raider it would be a solid upgrade. If building new, there's no contest, 7800X3D hands down.

Waiting on VR reviews especially DCS specific but right now it kind of looks like I may be staying with the 7700x.
