I'm trying to get ram theese OCZ Flex 9200 to work @1200. For now i'm trying using 2x1gb, just to be sure they can work.
I'm using a 450x8 wich run stable with ram @1125 (2.3v) and PL7, vNB 1.41, PLL 1.50 and FSB Term 1.3.
I'm aiming to set ram @1200 wich lets me to use a PL6, but blend test with prime95 puts out error within 2-7 minutes, every time on a different core.

I've tried running memtest86+ v2.01, not for very long time, about 2hrs and passed 7 full run without error, so i'm assuming that ram can keep this speed?

I've also messed around with vNB (up to 1.55), VTT (up to 1.38), PLL (up to 1.58), tried PL of 7 and even 8, but none of these trying lead me to anything: everytime i've got error within the first 7 minutes of run.

What can i try?
