Why I think this is:-
a) you are not OC'ing RAM above 1250MHz, OC'ing RAM can cause BS.
b) you have tried the MEM Clock 2 plus RAM Freq DPM 1 & 2 mod.
b) you have BS even on 290 ROM, which would set VID per DPM as required by GPU.
c) you are getting BS on 3D load, IIRC the BS occurs due to display signal corruption, modding 0.95V rail tends to stop signal corruption.
a) I have set RAM 1375MHz before, but It runs 1250MHz stock clock now.
b) I have tried the MEM Clock 2 plus RAM Freq DPM 1 & 2 mod on 290x unlocked last night. Still black screen. I'll try this on 290 soon.
c) Yes, just switch 290 stock bios, still BS. post #2836
d) Does modding 0.95V rail need a hard mod? weld some line on this card? It seems too dangerous. I'm worry about that It nothing help after I mod this rail. Just Try It?
the vid from aida64 is:
[ GPU PStates List ]
DPM0: GPUClock = 300 MHz, VID = 0.99300 V
DPM1: GPUClock = 483 MHz, VID = 1.21200 V
DPM2: GPUClock = 662 MHz, VID = 1.21200 V
DPM3: GPUClock = 841 MHz, VID = 1.20000 V
