Auto

200x21. QPI down to 7.2GHz.

Edit: As of now, IBT is stable with above settings so far.

My memory is running at 1200MHz rather than 1333MHz. Should not make a difference. Seem to be stable at 4200MHz so far

I will test all night. 1 hour IBT was solid. Temp decreased to 71c full load now it's cooler at night time.

Why does everyone like using high bclocks. In my experience all that does its raise your temps and vcore. Go with the highest multiplier available and start from there. Also doesn't enabling turbo on gives you use of one core alone instead of 4 or am I mistaken there/

From my experience you need to lower your bclk and higher ur multi to remain stable .. and ofcoarse ur vcore .
dont enable turbo. Not on 1366 and not at that high of a frequency. Having turbo enabled doesnt just increase your multi, it also increase single and double core multi's even higher, and increase voltage.

stick with the bclk overclocking.

bclk overclock vs multi overclocking, bclk acheive better performance.

Its best to have 21x multi i.e turbo on i7 920, me and bradley both know that.

Mine failed 4.2ghz tho , at 4.0ghz and 1.28vcore max temp 58C during gaming.
post #29 of 38
my 870 was overclocked both ways first with high bclock 200 and then with high multi 22. High multipliers gave me lower temps 60 c and lower vcore 1.28 vs high bclock @ 1.35 vcore and temps as high as 70c with water cooling.
HT and turbo off on both overclocks
