Hi,
I up my previous post and add several details: with the previous memory kit (takems ddr3 2x2gb) my cpu ran at 3,6ghz (400x9) @ 1.43125V BIOS voltage. It was stable, with a memory stick; because of one of this stick was bugged, the company will send another kit, and in the meantime I'm testing a gskill 1600mhz 2GB kit. With this kit at startup BIOS says "oc failed!". Why? Ram are for now underclocked (a few) and the cpu is OCed as it was before with the other memory kit.
Maybe I have to set RAM skew on my T3RSB PLUS?

What do you suggest to do? Thanks a lot in advance!
