Stuck at ~2480 MHz RAM clock with 3770, anything more I can try?

post #1 of 3
Thread Starter 
It seems I cannot get my IMC to run at anything above 2500 MHz. 2400 works just fine, increasing VTT/VCCIO to ~ 1.2 V gets me up to 2496 MHz (but not stable). After that, whatever I do, it doesn't help. So far I've tried increasing VTT/VCCIO and VCCSA to 1.25 V and 1.2 V, respectively. Also experimented with VDIMM and the latencies, but nothing...

Is there anything more I could try or a specific combination of settings, which is known to work well?

RAM is 2*4 GB Team Xtreem LV 2600 MHz CL10, 1.65 V on a ASRock P67 Pro3 with a 3770 non-K, normally running at 41*107.34 MHz, but of course I'm varying my BCLK to find my maximum setting.

If there is a PLL overvoltage option in the ASRock BIOS, try to enable it - it might help the IMC. If not, then ~1240MHz is already a very decent memory clock for a non-K chip, usually IMC on those are much worse.

PLL Overvoltage is not available for non-K frown.gif
