**WANT 8GB 2400MHz FOR AS LITTLE AS £59.99 Inc. VAT? - THEN CHECK THIS THREAD OUT!!** (MV-3V4G3D/US)

Right I'm still having loads of problems I really cant get much of a clock out of these.....

I have tried 2000mhz at stock timings with 1.6v and 1.1 VIT, 1.0v IMC.....buts still getting errors on prime straight away....

Any ideas? I'm on the latest bios for my board...

Have you tried the settings with only 1 module installed?

Then swap them out and try the other on it's own, settings might work on one module and not the other. Just a thought.

Are you trying to do that with a 4.5ghz CPU overclock? Although 2000mhz should be easy, a lot depends on the CPU IMC and there is some co-dependence with the CPU. If I push my CPU too far the memory overclock becomes unstable too. It's best to find the limits of both independently, then find a sweet spot that both will coexist at.

Try backing off the CPU and focussing on the memory only if you're not doing it already,

try one or two clicks more dram and or cpu vtt voltage,max safe vtt is 1.2 and dram you can use upto 1.65v more if needed but you shouldnt need that much
 
on z77 yeah,keep an eye on the latest beta bios's though,they should have improved compatibility by now

even i needed 1.63v with 16gb on an asus z68,8gb only needed 1.55v @2133mhz
 
I've been trying to OC my Green, but it seems to default back to 1600MHz.

I've set the timings in 3D BIOS to 11 11 11 28 at 1.5V VDRAM, and when I select 2000MHz, save and close, it posts as 1600MHz in CPUID. Any pointers gratefully accepted!! :)

i think youll need more than 1.5v dram with 16gb and a gigabyte board,its not the ram its more likely the bios support for it

id test with around 1.6v dram and maybe 1.08v cpu vtt
 
New UP4 TH F8 BIOS has really helped this ram. Now clocks at 2000MHz 1.4V instead of 1.65V CL9-10-10-21 114 CR1, but I wan't more numbers...any failsafe timings/volts for 2133MHz?
 
Hm almost the same lol, love this ram! Gonna go for it.

done: Using same at 1.5V at the moment, :D it didn't like 9-10-10-21 though.

I jumped on this bandwagon, bought 8Gb to use with 3570k, GA-Z77X-UD5H.

i ran super pi at 9 9 9 24 2133 and it worked fine but after trying to go further and failing i now cant go back to my 2133 speed even after a cmos reset.

Any ideas?

what cpu vtt did you try?
 
I hadn't played with it to be honest, so i just checked and auto is 1.05v, I see the advice above is 1.1 for Gigabyte boards and 1.2 max so i will experiment but i was just curious to see if anybody knew of a reason i wouldn't be able to revert to settings i previously had working.
Maybe it was just a fluke the first time around!
