need help OC e6850

[qtnguyen87]

i have the following:
E6850 3.0Ghz
Abit IP35 Pro
4GB DDR2 800 Patriot
600W BFG PSU

i need help ocing this, what should i do to achieve atleast 3.8Ghz stable. I have an OCZ A50? CPU Cooler with AS5

please help!

What have you done or tried soo far? So everything is stock clocks ?

With air cooling OCing your CPU will get very hot depending on the vcore.

You should aim for 3.6Ghz and take it from there.

You can do this 2 ways. Adjust the multiplier or reduce multi and raise FSB

example. 366 x 9 = 3600Mhz. That should be your target for now.

Change CPU voltage to 1.36v or soo. Maybe 1.38 vcore. let us know gl and you can put your sig of your rig do that so we can help more. thx

To overclock a C2D, set RAM timings manually, drop the RAM multiplier to "2.0" (gigabyte mobos), or "1:1" (other mobos). This means that the base RAM mhz (not the DDR rate), will be the same as the FSB. Then crank up the FSB, and test with stress-test programs. When they fail, increase the vcore. Watch your temps too, don't let them get too high (80C).

Stress-testing programs:
LinX
IntelBurnTest
OCCT
Prime95

Monitoring programs:
HWMonitor
SpeedFan
CoreTemp
RealTemp

and of course,

CPU-Z will tell you the actual clock speed that you are running at, as well as your RAM timings/speed.

Edit: Most P35 mobos are good for 400FSB, and some are good for higher (420-450). Note that if you have DDR2-800 RAM (400Mhz base clock), then you will be overclocking your RAM too if you go over 400Mhz FSB. You might have to bump up the RAM voltage, and/or the northbridge voltage too, to get over 400 FSB.

I did a Google, and on that board, you might run into vdroop issues that prevent you from going to 3.8. I think 3.6 should be doable though.

Good post Larry.

I think 3.6-3.7 is doable. I had an e6750 stable at 3.714 GHz stable for two years before I swapped it out. Can't remember the temps or voltages and other settings as it's been quite awhile. Make sure the cooling is good and the RAM is of good quality. Otherwise I think the previous advice is right there.
