Need help with i7 Overclocking

post #1 of 10
Thread Starter 
Hi folks, so i can get my i7 920 stable at 4ghz with 21x190 and 1.325v, the memory is just under rated speed of 1600mhz and at 7-7-7-20.

For some reason i now need 1.325v stable at 4ghz instead of 1.30, but i was hoping you guys could shed some light on some voltage settings i should be setting manually that will help me overclock my chip further?

ive attempted 4.2ghz+ before, but even with ridicoloud 1.40v+ it couldnt handle stability?!

cheers

Don't leave your voltage at [Auto] setting. Set it to [Normal].

Auto means motherboard decides how much voltage to give and Normal means the stock voltage. Most boards are stupid and overvoltage.

Oh well then it's only valid for Gigabyte boards. I never leave my voltage settings at Auto.

When it comes to your problem, increase QPI/DRAM voltage.

ok so ive gone with 19x210 multiplier for 4ghz this time, to increase my ram to nearly 1700mhz. All settings are at thier lowest in terms of volt, apart from vcore which is at 1.130 and qpi is at ike 1.30

Cool. 1.35 qpi is your maximum for 7/24. So try increasing the multiplier to 20?

I believe it is better to test and see for yourself rather than believe others. Every chip is different you know. So who knows you might be lucky enough to run your chip stable with that multiplier.

certainly is interesting, after 4ghz I have had to up the vcore and qpi but even after like 5 increment increases on both my comp just locks up after 60 seconds once i try to run IBT
