Running a round of Prime95 Blend to see if it is actually stable: if it doesn't fail to quickly I'll leave it overnight, and if it is indeed stable, we'll have a clear culprit, tCWL.
Hi, I am currently running 4 x G Skill F3-12800CL7-2GBECO dated 2010Oct in my Asus Sabertooth P67.

I need to run it at minimum 1.425v to operate at 1600-7-8-7-24-2T.

Here are the sub-timings that AIDA64 reports you need to run it best 7-8-7-24 (CL-RCD-RP-RAS) / 40-88-2-5-12-6-6 (RC-RFC-CR-RRD-WR-WTR-RTP).

I am running Write CAS Latency (tWCL) 7T and everything is great.

Not had great luck with overclocking 100% stable, but will report more if I do.
