OC my E6750

[Wingo101]

My C2D is currently running at 3.21GHz, how high can I push my clock?

I want to get maximum performance from my CPU.


EDIT: I have inserted some screenshots below.

First try upping fsb by 5-10 increments. o.o just noticed he cpu vcore really high so ur oc might be limited.

Mines at 3.6ghz at 1.4v(liquid cooled) and does 3.2ghz at stock voltage,same chip.

Will it not go any higher? have you tried going higher on the fsb at 1.4v?

Mine did exactly the same clocks as above in a p5k-premium.

What speed is your ram,6400,1066?

Is there any way I can lower it?

BTW: I will post some screenshots of my BIOS a bit later.

I can get it to 3.4ghz-3.5ghz without changing the voltages.

My ram is running at 800mhz.

BTW: I'm currently using my cellphone to post this, so please excuse the format.

Here are some screenshots of my BIOS

Which settings should I change?

Anybody?

On ur second screenshot, u have cpu voltage. Lower it to 1.35V. Then set ram timings to 5-5-5-15 and start upping fsb.

 

[Wingo101]

My RAM is rated at 4-4-4-12, why should I change it to 5-5-5-15? What's the difference?

Loosened timings might be slower but it helps pushing the cpu further. If u want to experiment, stay with 4-4-4-12 and just up fsb.

If you raise the frequency of your ram you will eventually have to loosen the timings to allow it to run. Your fine at 800 4-4-4-12. Set the cpu voltage down to about 1.35v, raise the fsb to 450, and see how that works. You may need to loosen the timings a bit to run at 900mhz, but try w/ stock timings first.

If I lower my voltage to 1.35v will the CPU still function, ain't I suppose to increase the voltage?

For some reason your voltage is set very high. The stock for that chip is from 1.25-1.35 depending on the revision. Mine runs at 3.6 (450fsb or as I use 515fsb) at 1.35v. If you run core temp or real temp you should get the VID of your chip, or stock voltage. At the voltage you are currently at you should hit near the max clock of the chip on air (which depends on the chip, mine will get about 3.9ghz on that voltage).

Yea but for ur current speed, 1.35V is enough and just makes u waste electricity.

If I take my FSB to 410, my PC gets a BSOD as soon as I enter Windows.

At what voltage? The settings above?

Then try upping CPU Vcore. Don't go past 1.5V. When stable check "LOAD" temps.

It's at 1.3625

Which one is the vCore in my screenshot?

EDIT: Never mind, it's the one I've been changing this whole time isn't it?

 

[spearman914]

CPU Voltage. Vcore is just the other way around "V"oltage "core"

I'm running one on a intel fan at 3.6 at 1.478cpu 1.54 pll and VT at 1.40 1800/450FSB stable.

I can't get 4.0Ghz stable with a phase even well it does not to be frozen....I think I could on water. I can almost with this fan but I think it needs around 1.50 for it...that's just a tad to much for this cooler.

CPU voltage. Check cpu-z in windows to see what kind of vdroop your getting (how much lower in windows it is than the bios, especially under load). Up it a bit though and see what happens. You may need to mess w/ the NB and termination voltages a bit as well.

W/ a 6750?

I don't trust CPu-z voltage read out....it says 1.52 for me...I don't think that's true at all.

What does everest say? Everest and cpu-z tend to report the same voltages for me, so I trust them.

 

[Wingo101]

Is it safe for my RAM to be running at speeds greater than 800MHz?

EDIT: Everest = 1.34v
