clocking potential (1090T, G.Skill 1866, Sabertooth 990FX)

post #1 of 8
Thread Starter 
If anybody could give me some recommendations to try... I'm looking for a mid range overclock settings, nothing extreme. I rather not even up the voltage much, if at all. This will be for long term stable setting. I am overclocking a bit right now, but not sure if I am way under full potential. Once I pick a setting, I'll do PRIME95 for 8-10 hours to make sure it's stable. Also may run Memtest for 8 hours.

I'm at 4.12ghz right now on my 1100T in the sabertooth... I'm having to feed it the volts though...

265x15.5 = 4.12GHz @ 1.525v
2920MHz CPU/NB @ 1.36875v
2120MHz HTT
DRAM @ DDR3-1766 9-9-9-24-1T @ 1.65v

My CPU refuses to go very much above the core clock I have right now. I am working on getting this 24hr prime stable, then I may push it a little harder, but my voltage is about the most I want to go right now. Also, if I drop the voltage at the core or cpu/nb much, if any, I will not pass IBT at very high stress level. I got prime95 16hr stable with 1.3625v, and I need to see if 1.36875 will work out for 24hr.

I've had better luck using the base clock and lower multipliers also.

ive read that the AM3 processors can't utilize the 1866 ram, even though it looks like I had no problem doing that. So not sure what they're referring to...confused.gif

You just have to overclock to get there, I believe it has something to do with the dividers that are available to an AM3 proc, I could be completely wrong though. I base this off the fact that I can not use the highest divider setting for my ram, the pc wont post. So I just get up to 1766 (or higher maybe!) by using base clock and changing all my other multipliers to where I need them to be.

i just put my timings down lower 9-9-9-24 1T and changed the freq to 1600MHz instead of the 1880, wondering if lower timings, or stock timings and higher freq would be more beneficial.

I noticed that 1412 @ 7-7-7-22 got me better latency, but less bandwidth than 1766 @ 9-9-9-24

You think the 1766 @ 9-9-9-24 is more beneficial than stock 1866 speed and timings?

What are your timings at 1866? I would suggest setting it one way, then the other and bench to see what your rig does... I personally am going to go with 1766 @ 9-9-9-24 because its a tad more stable. But I have cheap ram.
