32GB Samsung Ram (8x4GB Sticks) can't get passed 1600Mhz on Rampage IV extreme - Page 2

Oohh ooo. Ericeod.....back to the BIOS for me to check my DRAM ref Cycle time. Thanks for the PICs,

OK changed the timing exactly like Techpowerups:



Going for a 2133Mhz OC fingers crossed.....prime'ing....no dice...

Timing were tightish for this RAM at 11-11-11-28, I'll slack'en off alittle to 11-12-12-30 2T and try again...

Na still no good...I had a quick look at the overclocking section of the article which had the following secondary RAM timings



I tried these to, but no good at 2166Mhz unstable in only 60 seconds of prime'ing. Not much increase in performance either



I'm going to drop back down to 1866Mhz and see if I can get tighter primary timing with these secondary timing's...

Cheers! Yep sign me up for the 1866Mhz club. I'm sticking with 1866Mhz managed to tighten the timing a little to 10-10-10-28 1T.

It appears going to command rate 2 or the secondary timings shown above are both stable at very similar performance, hope this thread will help anybody else OC there 32GB of Samsung 30nm RAM. Thanks for all the help on this thread.

Next OC my GTX 670x currently got the GPU clock offset to 151Mhz+ stable'ish, going to OC the Mem Clock next what an excellent guide by SeanPoe for doing this
