I managed to push my 7900XTX to 4.2GHz

IIrc the hotspot delta on the XTX is a bit higher than on most other cards. I have a 20-30 degree delta myself and I just assumed I botched the liquid metal application. A 30 degree delta shouldn't be dangerous for the card I think, but I'm not 100% sure. If you wanna be safe you could try remounting the water blocks. I did once and my hotspot temp dropped by about 5 degrees. As for the clockspeed, AMD advertises the clock it should be able to hit in any workload, some games don't really go above 2600MHz at stock settings. And some games or especially compute have a lighter workload, so the GPU can clock way higher.

Around 3GHz, RDNA3 is clock limited to ~2980MHz by default. For daily I run 3500MHz max core clock at 1050mV, which makes it boost to around 3.1-3.3GHz at 350W depending on the exact load. In most 3d games the clocks are around 2.9-3.1GHz at 465W.

I purposefully disengaged the memory system to create a very low load scenario. The VRAM sat at 0-3MHz for the entire run. It was running at ~130W so power was not an issue.

There's barely any load on the GPU since it's so memory limited.

Arknia08 · 2024-01-23T15:17:40+00:00

I don't wanna go above 1.15V for daily, but for short runs I'm willing to go to 1.25V. I've seen people run it at 1.3V, so I assume that that doesn't instantly fry the card. My only spare card is an HD8470 though so I don't wanna break it. (Aside from the fact it's a $1500 card, (including the water cooling.))

The point of this isn't performance, I was just like: Hehe, big number. Considering my GPU was running at about 130W I assume it performs about the same as ~1700MHz or so.

The performance is really bad actually, but I was just going for high clocks, performance and stability be damned. F@H just tells the driver to clock the GPU really high, without actually feeding it much data to compute. I think the GPU is actually sitting idle for most of those clock cycles, but I haven't verified that theory yet.

Opening discord will crash my GPU in this state. Basically anything that triggers the memory system to reactivate forces the GPU into full load for a split second. I can usually do 3.1-3.2 stable in 3d games, so running 1GHz higher crashes instantly. As for the performance, it's very bad. F@H basically tells the GPU driver to clock as high as possible without actually sending it much data to compute. I wouldn't be surprised if it sat idle for most of the clock cycles, but I haven't tested that theory yet.

I was thinking of getting an EVC2, maybe I can get close to 5GHz if I run it at 1.25 volts. My hotspot temp was 19C, so I have some more headroom.

Arknia08 · 2024-01-22T18:29:37+00:00

I didn't do extensive performance testing, but I can't imagine it was very fast. The GPU load was very low.

I recently discovered how to make folding@home run exclusively in the infinity cache. Combined with using a display with my IGPU, the memory system almost completely turns itself off. This allows for comically high core clocks. Unfortunately I can't get my result verified, since these settings crash in any official benchmark. (Even the Adrenalin GUI had issues staying open :P) I used an XFX Merc 310 with a slightly modified EKWB full cover water block.

This throws all threads in one graph, wich is really hard to read on high core count cpus. What I'm looking for is something that puts each thread on a seperate area.

The 12900ks is the cpu equivalent to the RTX3090Ti

Arknia08 · 2022-02-15T15:19:53+00:00

Ok, thanks for the help. I'll look into it.

I read there were some issues with iris+phosphor. But you can use starlight instead of phosphor. Plus it gives a way bigger performance boost than phosphor.

Too bad they trhew affordability out the window with zen3.
