second monitor view:

some info:

  • this has only happened in one game (Total War Warhammer 3) and the card has been performing more or less fine otherwise, although i have been noticing some minor artifacting in stuff like Firefox.

  • my PSU is old as fuck and technically underpowered for the card (EVGA 750W gold from 10 odd years ago) and I’m also using a 2 head splitter cable to power two of the three 8 pin headers.

  • CPU is a 9900k which is certainly throttling this thing

my thoughts are to just buy a new PSU and see if that fixes it. i can RMA anytime so I’d rather wait and see. just wanted to hear some folks thoughts as this is stressing me out a fair bit

    Power delivery is where I’d start

    Pink blocks and static are somewhat indicative of faulty vram but you’ve got some bad power situations going on

    Underpowered psu is obviously no good though 750W should barely cover a 9070+9900(unless you have like 80 hard drives or some crazy water cooling radiator or something). 850-1000 would give you more headspace for sure. 10yrs of use especially in high heat can drop transient voltage rating because capacitors age so the 750w might be more like 650-700w and that could be your issue there. Depending on the settings TW would totally push things so this could be it

    Verify temps

    After that eliminate the splitter - creates resistance and adds voltage drop/instability

    After that driver issue - clean install

    Quick checks for hardware fault - test in another machine if possible, see if artifacts show up in bios settings screen, run a gpu stress test like furmark and see if artifacting shows up very fast (though if you still have power delivery issues these might all fail so keep that in mind)

    After that I’m out of ideas. Cable?
