hahahahaha ill believe you this time lol roll on january

I think your post had merit, this lad changes computer hardware and displays more often than most of us have hot dinners.

At least I've had my XTX for 8 months now without a change!!

My chip/IMC is quite strange. At 1.27v, I was getting FCLK errors in P95 large FFT’s. That’s at 6400CL28 and 1:1 with 2200FLCK.

Dropping the VSOC to 1.17v stabilised the FCLK and the RAM stayed stable.

High FCLK does often need lower soc voltage to be stable, but I was quite lucky that the RAM stayed stable at a lower VSOC. I think I have a very strong IMC.

That being said, I would rather run 64001:1 2200FCLK with a 1.3 VSOC than 8000 2:1 with a low VSOC.

8000 is a flexy number, but outside of synthetic benchmarks and productivity, it’s not worth it. 64001:1 is consistently shown to outperform it in games.

To outperform 6400 1:1, you’re likely looking at 8400+

Need to try that for myself, dropping FCLK that hard

But you are right, 8000 < 6400, but it gets close in terms of latency not bandwidth.

As for you settings, you should be running 2133 not 2200 ... you'll see your latency dropping

lol build zoid made a video yesterday with my exact motherboard and ram!

9800x3d 5.6ghz overclock

Alright, I realised my Curve Optimiser wasn't stable. OCCT and everything else passed fine, but STALKER 2 crashes. Turn off CO, no more crashing. This means I just want to run the CPU at stock, but at stock my Noctua dual tower cooler runs in the mid 50s at idle, which is ridiculous. Does anyone have cooler suggestions that will fit in a Meshify 2 case?

do you have the noctua offset bracket? if not grab it for for a cheap return on lower temps, it sounds like you may have backgrounds tasks running and therefor not really idle.

what was it set to?

STALKER 2 crashes even at -20.

do you know what the temps are around the time it crashes? what were the rest of your settings? I have PBO enabled +200mhz -30 curve x10 scaler. Was the ram expo enabled or just custom settings?

Temps are fine with the undervolt - 70s when gaming. EXPO - yes. I have further confirmed that turning off CO fixes the crashing in this game. If it has to be less than -20 I cba to be honest.

What does scalar actually do? I have -30 CO, +200 MHz, have tried 10x, 2x and default scalar and they all seem stable and perform the same

A lot of people’s CO won’t actually be stable if they fully stress tested the CPU.

I had mine at -30 and it appeared fully stable. Games, web etc etc. As soon as I started stressing the FCLK in YCruncher, I started getting errors relating to the CO. Had to drop it from -30 to -20.

A lot of the time, you won’t notice it’s unstable. You could probably get away with running it unstable etc for games and be fine.

But a lot of people that think their’s is stable, especially at -40 etc, are probably mistaken if they fully stressed it.

It allows the CPU to be supplied with higher voltage which in theory should lead to more sustained clocks.

I have mine at 10x from the get go. Will it cause degradation? Maybe, maybe not. But it won’t appear until long after I upgrade anyway as I upgrade every gen.

9800x3d 5.6ghz overclock

Only achievable if you have a motherboard with asynchronous eclk, which are reserved for the high end. I sink lots of money into my rigs, but don’t overspend on motherboards.

I tried a bog standard manual overclock at 5.55 ghz and 1.35v. Wasn’t stable. Might be able to do 5.5ghz, but it’s pointless and won’t really yield higher performance than PBO+200mhz offset.

 

[matty007]

STALKER 2 crashes even at -20.

That’s odd that it’s Stalker 2. Even at -30, which was unstable in YCruncher for me, it didn’t crash. It’s usually Warzone that makes CPU’s **** the bed.

Great game btw (Stalker 2)

After a couple of hours of toiling I finally manage to boot into 8000mhz on the X870E hero but no matter what I seem to change memtest errors out after a few minutes so I think ASUS needs to sort out the bios, even the 6000 preloaded profiles wouldn’t boot and had to start from scratch just to get that speed working.

overclocked to 8000 or is it an 8000 rated ram stick? I managed to get https://www.gskill.com/product/165/390/1723430443/F5-8000J3848H16GX2-TZ5NR running on it fine with just expo profile enabled and nothing else. But the board was overkill for me so I returned and swapped it for an msi tomahawk.

VDD/VDDQ Voltage?

If you see my post above on the same page, I think I solved it. Running OK temps now.

Are you by any chance using a 'thermal paste guard'? I expect what might have happened to me is that this came loose and covered the CPU as I installed it. When I took the DH15 off, the AM5 guard was at an angle.

Might be worth a check! Or this had nothing to do with it... and it was the re-seat that sorted it.

I had the exact same issue with a NH-D15. When fitting it must have moved the paste guard and it was partially over the CCD. I was wondering why the idle temps were high and then remembered your post.
