Hi there! First post on TPU!
I recently bought a Sapphire 7970 NON OC version with the blue PCB, one of those close-to-but-not-like reference models. The exact model number is 11197-11-40G. Everything is nice and all, but there's this little problem that is killing my OC. The card has massive amounts of vdroop on the core under load, checked with a multimeter. For example:
VID ------- vcore idle ---- vcore load ---- multimeter idle ---- multimeter load ---- vdroop
1.300V ----- 1.299V ------ 1.175V --------- 1.298V ------------ 1.163V --------- 0.136V
With a lower VID, say 1.200V, vdroop is lower but still around the ~0.1V mark. As you can imagine this is bad for OC and for the card itself.
Any suggestions or mods that don't require any soldering? I can take photos of the PCB if needed.
Thanks!!
