Need Help OC my E6750

post #1 of 6
Thread Starter 
Hello I know a little bit about overclocking but normally don't do it. Well this comp is about 2 years old and I haven't overclocked it on this board because for some reason I couldn't get it stable. The reason I want to overclock it now is because the CPU is holding back my GTX 280 and newer games aren't being able to max out. Like COD BO averages about 40-50 FPS.

Current Specs are:
Intel E6750 @ 2.66Ghz, I want 3.2 Ghz, and maybe 3.6 Ghz if its low temps and stable
Cooling: Zalman 9700NT
Asus P5N-D Motherboard, Vdroop mod done
4x1GB Corsair XMS2 DDR2 4-4-4-12
EVGA GTX 280
ULTRA 600W PSU
Windows 7 Ultimate 64 bit

I average about 43-45 degrees temp for my CPU. The CPU Core volt in CPU-Z is 1.264V.
I did 1.35V in Bios and it read it as 1.31V in CPU-Z. Ht 2.1, VTT 1.38, NB 1.38, and SB auto. This isn't stable, freezes during game play. I get about 52 degrees after bumping up the voltages. Isn't pushing over 1.35V alot?

No, on my e7300 I pushed it to 1.46 volts and got to 3.8 ghz. I think you're fine, as long as you can keep tour temps low when under load.

Yea see I thought 42 degrees was a bit high for an aftermarket cpu cooler for stock speeds. I thought I should of got at least around 35 degrees. Well I tried bumping up the voltage core to 1.4V but my temps seem way too high to me. I go to bios and get 58 degrees. And in HW monitor get around 61 degrees. Isn't 60 degrees on idle too much? Because I am sure if I stress it, it might go up to 90 degrees.

60.C idle is very hot, for idle. what speed is this at.
IF ITS AT STOCK SPEED 2.4GHZ, THEN DO NOT OVERCLOCK
you must have not fitted the cooler properly.
try reseating it, and also what thermal paste did you use?

your bumping up the voltages in what stages?

all i do, is raise the fsb until pc cant boot, raise the voltage a notch or two.
raise the fsb again until it doesn't boot, and again raise the volts, and on and on and ........
its boring but slow and steady
that way i dont have too much volts (and heat) when i dont need to

edit.
what are you trying to get? have you tried overclocking it already? reset all previous settings to default.
the default is 333 x 8
unlink the ram. and keep it at default speed

now just add 20 to the 333 in the bios, so its 353, then reboot,
now run Intel burn test (IBT) for 5 passes. keep an eye on temps.

in bios add another 20mhz so its 373 and boot again and run IBT.
keep doing this until it wont boot, then add a notch or 2 of voltage and go again.
keep doing this until you get to 400 x 8 = 3200MHz or 3.2GHz
now you can try and unlink the ram, if its 800mhz ram pc2-6400, your ram will be equal to your FSB, so in cpu-z you will have a 1:1 ratio

also your chip can go to 1.5v http://ark.intel.com/Product.aspx?id=30784

and use realtemp or coretemp for temps.

I get around 42 degrees at stock clock. I use the Arctic Sliver MX-5, the one everyone is using. I think I installed the Zalman 9700NT correctly but it does seem loose because I can somewhat spin it. Well at first I changed the setting to unlink: FSB to 1600 and Memory to 800. And yes I get 1:1 ratio in CPU-Z. I started at CPU VID: 1.35V, HT 1.38V, NB 1.38V. Slowly going up to VID: 1.40V, HT 1.42V, NB 1.42V still not stable but the temps were kinda too high for me. It was around 55 degrees idle at these temps. And when I did the stress with Prime 95 went to as high as 80 degrees. I feel like if I move it higher, I will hit 60 degrees idle and thats gonna be high.
