    Yeah anything 4004 or higher sets 8GHz ram as long as a I don't touch the base or boost clocks. 6GHz if I touch those. I also tried again to mod the P4000 device ID to be a P5200. That failed again. There seems to be some security check beyond checksums to check the device ID. Also, I tried 10GHz again, but it just ran 8GHz. My guess is I just got error 43 before due to bad card seating or something, and not due to the card trying 10GHz. I also tried undervolting in hardware since we can't in software. The problem with this is the GPU core still has the same target voltage, so when I supply a lower voltage the on-die droop detectors engage and start clock stretching (This is a frequency loss not reported in software since the GPU is still requesting 1708). I dropped power draw by 10%, but dropped perf 1-4% depending on the test. So really the only way to undervolt without perf loss is bios modding if we could figure out how to mod the VF curve.

    So for all 3 vbios that work, all 3 can OC memory to 8GHz. I did try one at 10GHz and the card went error 43, implying that it actually was trying to run 10GHz, and failing. Maybe a big VRAM overvolt to 1.65V or something could get 10GHz working, but I think I have a good chance at killing the card trying. I have been trying just adjusting the max clock and not touching base or boost blocks. This seems to permit constant 1708MHz on the core, but no higher. Touching the max clock only does not seem to be wrecking the vram clocks.

    I tried 9.5GHz (4756 in tool), but that also just resulted in 8GHz. My understanding is 9.5GHz is about the best possible out of GDDR5. I might try 10GHz at some point just to see if it gets set. Yeah modifying core clocks ruins the memory OC and causes 6GHz. I'll try modifying individual clocks to see if one in particular triggers it.

    I found that your tool can OC the memory to 8GHz. The memory locks to 6GHz if I try modifying core clocks while also overclocking memory. If I don't touch memory at all, then it runs at 7.2GHz even if I adjust the core clocks. I can't get it to try anything faster than 8GHz. I've tried setting up to 9.2GHz, but it still just runs at 8GHz.

    Interesting that there are 3 locations for memory clocks, but only one needs editing. There are 3 memory options for the p5200. Every p5200 in the world other than mine has option 0 set. On mine I had to set option 2 for 8GB since I core swapped a p5200 onto a p4000 card. Maybe your program is only editing option 0 instead of all 3? I can cycle through the 3 functional base vbios tomorrow.

    The MSI one failed to overclock though. Still 1709 max. Can we try a 9GHz for the MEM? I tried your tool, but it was reporting 7.2ghz instead of the 8ghz actual.
  7. Khenglish
    Success!

    GPU-z always shows 1709 as max boost clocks. For RAM it depends on vbios. For the 3 that work on the card: vbios 1: Will show the overclock, but run at 6ghz. vbios 2: Always shows as 6ghz even unmodded, but will properly run 7.2ghz. It always displays 6ghz and runs at 7.2ghz even if overclock modded. vbios 3: Will both show 6ghz and run at 6ghz if overclocked. If unmodded displays and runs 7.2ghz. I might be mixing this up some, but it's something like the above. The card can only run Dell vbios. MSI and Lenovo both crash on an Nvidia driver. HP does not work at all. The card itself is a Gecube card. I have not found a gecube p5200 vbios.

    The tool does seem to raise both base and boost clocks correctly, just not the max clocks. Without mods, the card only runs 1709MHz if under 50C. With mods it will maintain 1709 over 50C and just bump the voltage up from 0.85V to 0.862V instead.

    Time Spy with 150W power limit (effectively no limit). Also, the power slider does work. Only Nvidia Inspector (NOT Nvidia Profile Inspector, you need Nvidia Inspector from ~2017) can control it, but it works.

    Raising the TDP does work though. This is 125w vs 110w in firestrike: systeminfo doesn't work, but this is on a P150EM with a 3920xm at 4.3ghz that is modded for direct dGPU display output.

    Multimeter. The card runs memory at 1.35V, except for the max speed bin (7.2GHz) runs at 1.5V. The P4000 runs 6GHz at 1.5V since that is its max memory speed. The OC bios had the same issue. No core overclock. RAM would only run 6GHz. The card cannot run an Nvidia driver with the MSI vBIOS.

    Editing the attached P5200 vBIOS with v1.34 of your tool isn't getting me an overclock. If I overclock vram, the 1.5V speed bin gets ignored and it runs at the 6ghz 1.35V speed bin. Raising the core limit over 1708 is also ignored. Currently I'm trying to set 8GHz on the ram. I am using the #2 memory strap setting on the card instead of #0 like every other P5200 in existence. idk if that matters for vbios vram overclocks. p5200_dell.rom p5200_8000_2.bin

    Windows is very insistent that v1.3.4 has a virus in it. Also, do you have a way to effectively shift the frequency/voltage curve like normal overclocking? Ex: Can I offset clocks by +150MHz, or does setting a higher core clock just pick a higher frequency/voltage point?
  15. Khenglish
    The 330W power supply should be fine. These systems have a power limit set by the embedded controller and it can cause shut downs. The 9700K can cause very large, very brief power draw spikes that can trigger a shut down when combined with a GPU load. I recommend using Intel XTU to lower the CPU current limit. This should be much less impactful on performance than undeclocking the GPU.
