Need Help Reaching 4+ghz 955 BE

post #1 of 5
Thread Starter 
I think I finally fixed the issues i've been having with my system and everything seems to be running great.

Running Prime95 @ 3.2ghz, CPU/NB Voltage @ 1.4v, RAM 7-7-7-20 1.9v 1600mhz, and everything else on auto. My max CPU Temp at these settings is around 44c.

How much room do I have for improvment? 62c is max on this CPU. Can I hit 4.0ghz on air??

Need help with the other setting i'll have to mess with (Multiplier, Vcore, buss speed, etc)

Hoping OCN will be awesome and help me get 4.0ghz! (=

Try these values.....
multi-- 18
fsb-- 226
vcore-- 1.48-1.5v
cpu-nb -- 2712(~)MHz
cpu-nb voltage -- 1.32-1.35v

While experimenting with these values, keep 'cool n quiet' and 'c1e support' disabled.
Dont tweak the ram right now, will get to that once stable oc is reached.
On second thoughts, while using that fsb, your memory speed might get increased upto 1800MHz. So, you must manually select 1600( should be near 1580) MHz for now.

It really all depends on your chip. Before I built my oil pc, I could hit 4.06Ghz on 1.44v and a Coolermaster Hyper212+. Seems like from what most people have said, 4Ghz takes at least 1.4v. Check out the 955 overclock spreadsheet thread. 4Ghz is possible on air, but it takes pretty good cooling.

Also keep in mind that increasing the CPU-NB voltage and NB frequency dramatically increases the heat of the chip, as the CPU-NB (Integrated Memory Controller or IMC) is physically located on the CPU die itself.

Add +0.1V
Your Micron D9 or Samsung HCF0 with 2V should be able to manage 1600 6-6-6 no sweat
Should be able to hit 4Ghz if you've got a C3 edition.

I got the C2 edition, sadly =/
