memory OC attempt

dacads · 8 Apr 2013 at 18:51

Hi, just tried to OC my Sammy Green RAM at 2133MHz using 9-11-11-21-1T if I remember correctly, but to no avail. I was left with no display on bootup which meant I had to reset the CMOS then I was presented with a lovely winload.exe error so had to insert windows CD and click repair computer which literally just restarted the computer and was working fine again lol. 1.5V was the voltage I used.

So yeah I'm no expert with OCing in particular, however I used the DRAM E.O.C.P which seemed to increase HT Link Freq and Northbridge Freq as well? I tried setting them back to default values with manual not auto but everytime I change the E.O.C.P they just automatically change again which is annoying.

id try with 1.55v and looser timings to start with,it might be different for amd boards

try with 11-11-11-24-2t timings first and 1.55v dram then try and tighten up the timings if stable

try these settings as a base

- 1600MHz (7-8-8-24 1N) @ 1.40v
- 1866MHz (9-9-9-27 1N) @ 1.40v
- 2000MHz (9-10-10-28 1N) @ 1.45v
- 2133MHz (10-10-10-28 1N) @ 1.45v
- 2400MHz (11-11-11-28 2N) @ 1.50v

Sorry to hijack op, but thanks for posting theese up Nickolp. Just installed 8gb of greens today, albeit in an intel Z77 setup, nice to see some figures to use as a guide.

Thanks for the replies guys. Should HT Link freq and Northbridge freq be changing or should I keep changing them back to the default values?

it will change along with ram speed

those above settings look rather optimistic with dram voltage,i find you need a touch more usually 1.55v tends to be the sweetspot
