I ent through a lot of issues trying to run 4.4Ghz with my set up. It is the i5 SB 2500k, GB P57A-UD3P-B3 and 8 GB GSkill Rpjaws X.
At 4.4GHz I used 1.34vcore, LLC Enabled, CPU PLL from 1.52 to various other voltages up to 1.8, QPI/VTT 1.05 and 1.1. Ram was left at stock 1333 DDR3 at 1.5v.
Although this was stable in IBT and LinX under 128bit binaries, it failed AVX LinX.
I then said what the hell and tried 4.8Ghz at 1.4vcore and crashed and burned lol. Cleared cmos and worked my way up again to this. It is now 4.2Ghz stable, i hope, with a low vcore. All other voltages are at or near default values.
Question is, should i stay put here or attempt another higher multi?
Heres the pic. Ambient temperature is 26C. Didn't realize the ambient temperature until i ran the stress. Turned on the ac lol. Temps should hopefully drop by another 5 degrees as it is nearing 22 degrees C ambient now.
Also another thing to point out. I ran IBT without AVX and temps peaked at 53-54 on all 4 cores. Did a short test run to make sure it could handle it before attempting the heavier more demanding stress; LinX. With Linx the temperatures rose a lot, but keep in mind ambient was also high.
Forgot to mention I set ram voltage to default at 1.5, ram at 9-9-9-21(default 7-7-7-21) and 1600MHz up from 1333Mhz.
