I have been struggling to squeeze ANYTHING extra out of these cards for hours. Nothing I do can even bring me up to 3400mhz from the XMP of 3200mhz. I tried way stupidly loose timings and even gave the cards 1.5V and I can only manage a post by sheer luck every few attempts. My only hint of success was tightening timings a tiny bit down to 15-17-32 from 16-18-36 at 1.35V. These d-die micron chips feel like they are already overclocked to their maximum right out of the box. If this is the case then I don't know that I can ever look at Vengeance again if I desire even a modest OC. Has anyone else had any better luck with these?
I attached a shot of Thaiphoon for reference.
