Hi there, not yet. I’ve seen other foruns talking about bugs in the nvidia drivers for this card.
I have no idea how to fix this, I’ll apply thermal pads for the junction and other chips around, just to make sure the vbios is not powerlimiting for some crazy reasons. “nvidia-smi -q” doesn’t show any limiting, so this shouldn’t be a thermal issue…
If you look in windows HWInfo you can see that one of the 8pins is pulling 100% 150W and that is the limiting factor. The Suprim X bios can negate it IN Windows with an increased limit making it possible to draw like 160W from this pin and get proper ~100MH/s.
Unfortunately, it does not work in HiveOS. In HiveOS I and some other users found out that you can flash other bios like EVGA FTW or Gigabyte Aorus Xtreme and the card is capable of hashing normally. It will mess up sensor readings tho. Mine is now set to 304PL and is doing just fine. The power draw from the wall is normal even with that PL set as that is just software reading.
This is some kind of BIOS limitation on this Gaming X. Kinda sad as Suprim and even Vision are not affected
Nope, I did not test on any other Linux distro. It is possible that it can be a driver issue but if it was, why is it also present in windows? I think Linux driver still limits power draw from components like 8pin to the specification of 150W but in Windows increased Power limit is able to overwrite it, like I said, it can draw above 160W if you set power limit with Suprim X bios to like 105+%
After BIOS flash I replaced thermalpads. Used Grizzly 8 minus ones and I also added some more Noctua thermal paste to the mini metal plate that connects Memory modules → Pads → Metal Plate → Paste → Main heatsing (who thought of this design!? total bs imo)
I tried around 20 different bioses, I took them from techpowerup.com. I tried All MSI ones, Suprim X only worked in Windows. Do not remember all of them but I know that those work in HiveOS
Gigabyte AORUS Extreme: 94.02.26.88.26
EVGA FTW3: 94.02.26.48.68
EVGA FTW3: 94.02.26.48.88
It is possible that other FTW3 and Aorus Extreme BIOSes also work. At first, I thought that only the ones with like 400W+ will solve the problem but Suprim X also has that upper limit but is still limited
I’m not confident about flashing all 90 that are on the site to make sure which one work but it might be a nice place to start.
Beware, some things are weird if you flash those BIOSes and look in the HWInfo in Windows. It shows just 2 8pins iitc instead of 3. I’m not sure if it will have any negative impact in the future but for now It hashes just fine. It is a little bit lower compared to my other 3080 (if I set them to the same memory OC) by I do not know what it could mean.
The 3rd card that is shown as EVGA is the card in question. Well, bios flash also changed it as one would expect As you can see I use 94.02.26.48.68 BIOS.
Everything except PL works ± the same way. I found out that around 305 ± a few is where you wanna be with it. Do not worry, it is not pulling 305W from the wall and it is similar to my other 2 cards.
For the 3080s I use 100% fan only to keep mem temps as low as possible, they get kinda hot for me even with replaced pads. I did not replace backplate pads on this MSI tho and left what was there by default.
I wasn’t able (yet) to pad the cards and try the EVGA vbios hack, but I noticed something totally strange.
Try setting the “intensity” to exactly 92%, and the Power gets unlocked
In my case it does not compensate over the 8%, but you can try it. Somehow the card unlocks the power consumption, and you can tweak the mems. Haven’t tried it enough though, I need some good pads and thermal paste for the GPU. Any recommendation for pads or paste is welcome.
