Finally installed it and since I can't find much info on this stepping I thought I would share. So far so good. My sig says it all and I am quite pleased so far at what little tweaking it needed for 2700mhz. It appears stable but I have to be honest in that I only ran p95 for 5 minutes and memtest for 10 minutes. Some posters have reported problems with higher vcore required than usual to get to this overclock but mine appears to follow the norm. All reviews so far come from DFI mobos so I can't speak for them but I would only suggest you increase your chipset voltage before increasing vcore. You may notice an improvement. I had to increase it from 1.5 to 1.6v. So for anyone else trying, start from the beginning and when you've hit a ceiling with default vcore and you've ruled out your ram, up the chipset voltage a tad and see what happens. You may still have to increase vcore eventually but it shouldn't need to be set to ~1.60 vcore for 2700. More like ~1.4-1.45. This is just a suggestion when overclocking this specific stepping and ofcourse not necessarily applicable to all opty 146's with this stepping.
