I've been playing with my MSI 3080Gaming X Trio for the days.
It can't do more than 86MH/s, no matter the temperature.
Issue is in the BIOS as when power reaches 205W it throttles.

I am using MSI Curve with minimum allowable voltage, 0.725 (in reality 0.731), and 1125MHz.
If I use normal PL level it does not do more than 82MH/s.
Also it must have a minus 120MHz on the memory, if I give it more it throttles instantly to 60-70MH/s.

Stay away from the Gaming X for minig!


PS. Yes, you loose warranty if: you change BIOS with any BIOS not destined for Gaming X (exception the 2 official ones= OC mode and silent mode - tested both, same 205W throttle limit), or if you remove the seal on the 4th GPU screw.

It's very strange, as I saw on some reviews, this card have TDP of 340w right?

I have an EVGA 3080 and I'm doing 98 stable, with 230w on software and 250w at the wall - I did fan curve to reach 1200Mhs on core clock with 718mv - 70% TDP
3080s are power hungry, and if I reduce even 1%, the card start to hash a lot less Mhs

I think your 1125Mhz on core clock is low, here I need exactly 1200mhz

But I don't know why your card only have 205w until throttle

Is it possible your card is having this throttle because of memory temperature?
Maybe after hit some temperature, the bios reduce the wattage to cool the board

I also tried 1200MHz, 1225, 1250, 1300, etc
The Gaming X is pure crap.

After seeing the VRM analysis I understood why. It has an underwhelming implementation that does deliver the necessary power but because it cuts corners in quality it overheats.
And as a cherry on the top the VRM and memory cooling is not efficient as the cooler does not have a coper base plate but direct contact width the heat pipes.
That is the reason for throttling at exactly 205W.

So I sold it to some one else to use it for mining (he did not care about warranty and wanted to add the Suprim X BIOS).

Now I got instead for the same money a Suprim X which does:
100MH/s @ 0.725V with 1250MHz Core and + 1200MHz VRAM, 60% Fan (1800rpm).

Now I am happy a camper  Grin
