Solved: i7 OC settings.

post #1 of 10
Thread Starter 
I''m new to this chip and figured it would be just like the 950, 920 etc to overclock, but it appears it's not. My vid is 1.10 but if I up the clocks to 4.0 and core to 1.35 and qpi to 1.35 it won't even post. I've backed everything down incrementally and tried everything and it seems like if I change anything in the bios it won't post. I'm obviously missing something. Could someone post their bios settings or point me to a guide? Thanks.

What bclk and multi are you trying for 4.0?

I've tried pairings of 25,21,20 multi + whatever bclk to get to 4.0

wow that's odd, what if you put in 25 x 160 and left everything on auto. What voltage would it default to?

I wonder with such a low VID of 1.1 why it wont react to 1.35

Im at 4.2ghz with 1.336V using 168mhz*25.0multiplier

Turns out qpi was way too high. 1.26v and 1.20 qpi cleared a few rounds of max burn test at 25x160. Booted to 25x160 and left everything else on auto which gave me a baseline so that was epic advice. Thanks.

Nice glad to help!
post #9 of 10
Glad you got it sorted!

I have done some experimenting with mine with the multi vs. higher bclk and ended up at 21x205 for 4.31ghz at 1.336vcore. This puts my ram just at 1642mhz which I find gives me better performance than having the lower bclk and lower ram speed.

Is your qpi unusually low as well? With my quad core I7's the uncore was always near the vcore. With this one its much lower.
