RAM overclocking

post #1 of 8
Thread Starter 
Im on the latest BIOS/UEFI for my board, F5h (GIGABYTE G170X-Gaming 5), my RAM is G.SKILL RIPJAWS V 2400MHz @ 15-15-15-35-2T @ 1.20 volts stock. I know the SAME RAM is also sold @ 2666 @ 15-15-15-35-2T @ 1.20v, & 15-15-15-35-2T @ 1.25v @ 2800MHz etc..mine CANNOT OVERCLOCK. In the SLIGHTEST..over 2400Mhz..yet instead of 15-15-15-35-2T itll EASILY do 14-13-13-30-1T at the same 1.20v. Im an "extreme" tester, i do memtest 86+ >7hours, Prime95 >8hours, Intel linpack >7hours, all is stable. Plus "generic" gaming usage, still all stable, if my RAM is a "unlucky bin" why can it do such a good timings reduction @ stock 2400MHz speed, but not even do 2666MHz? After much research i found GIGABYTE boards having "issues" overclocking various RAM..ive tried EVERYTHING..from memory multiplier tweaker to memory stability tweaker (may not be remembering it right), going from "normal" to "enhanced stability" helps quite a bit, but doesnt fix the problem. ONLY giving my RAM 1.24v fixes the problem. Yet im still not convinced its my RAM thats just a "poor OCer", cause even @ 2800MHz with 1.24v my RAM can't do that, when theres the SAME kits marketed to do this speed @ this voltage/timings. I get the "silicon lottery" but i don't get this, the descrepency is just too much..

Ive tried memory multiplier tweaker,, memory performance setting (normal, relax OC etc), VCCIO, VCCSA etc. The ONLY thing that will make it APPEAR to be stable (in mid term at least) is more RAM voltage, is there something im missing here? Yes my 6700k is "complete" stable @ 4.5GHz, ive done extreme Prime95 testing, handbrake, linpack, generic gaming, ewverything (all those tests are over 9 hours) its fine. Im not a "test it for 2 hrs its stable? Okay derp" user..any suggestions?

What happens if you set all the memory settings in the BIOS to their defaults and then increase speed?

Nothing, ive done that already. Stock voltage, timings, it hates anything over 2400 MHz. Yet at stock 2400 MHz, it'll EASILY do 14-13-13-30-1T over the 15-15-15-35-2T stock, it almost does 14-12-13-1T even.

It may be a cpu limitation.

Try the cpu at stock speed, can you clock the ram then?
post #5 of 8
Have you tried slightly increasing the cache / ring voltage? Also over clocking the uncore frequency may help.

I run CPU & uncore in sync @ 4.5 GHz, already tried VCCIO, VCCSA up to 1.20v which i wouldn't run anyway, without even 5 seconds of extra stability whatsoever. I'll try it @ stock uncore which is probably my next/last option..or tolerate the 1.24v on the RAM which is Intel's max recommended voltage short of absolute max, i know about DDR4 "easily taking" 1.35v as those kits are everywhere, im not fond of that much..

Ram OC isn't guaranteed just live with whatever you can get. It won't make too much of a difference beyond benchmarks anyway.
