Ok, I tried setting Drive Strength to weak mode and the 3 strengths of 1.50x to 1.0x. Posted however didnt go beyond 'FF'. Set the changed strengths to 1.25x instead and it booted and ran 32M SuperPI with 2.3V . DIMM's weren't very hot, warm though, I guess about 30~40C. Gonna play some more later on but Drive Strengths are awesome obviously.

Just tried 2.25V but that wasn't doing it, got the SQR error in SuperPI. However maybe a little more Drive Strength tweaking will solve it. At least I know one of the changed settings doesnt like to be at 1.0x. So Ill trial and error wise try to find the one(s). Also the original 1.0x Ill try to start at 0.75x.

Less Voltage and less Drive Strengths seem to be a sweet spot, at least for D9GMH. Voltage isnt much of a problem for me though, more worried about Drive Strengths as they can kill D9's if they're way too tight.

FYI, Ive a 80CFM 92mm fan pointed towards the DIMM's from ~10cm and an unknown CFM 120mm fan 10cm above the DIMM's sucking hot air out of the case. So Ill try and get better results.

I dont feel like changing the Ohm settings though as that seems a little bit dangerous.

AFAIK lowering Drive Strengths doesnt hurt performance, not sure about it really. Does anyone know?
