Default Suggestions on E6600 oc

Well I decided to overclock my PC that's in my sig for the first time. I changed couple Bios settings and I set a divider of 9x333 with 1.40v
in the Bios to start off but I'm stuck there. I ran PI 32M and it failed. My temperatures never went above 56. I set my memory to it's standard
timings (4-4-4-12 and 2.1V). I have posted a sceenshot. Any suggestions would be gladly appreciated. Thanks!

It's not advisable to just bump the voltage up all of a sudden. You should OC until it's not stable then bump the voltage up a bit and then continue to try and OC.

IGN has a GREAT starter article for this. Its a shorter version of the exact same thing nvidia put out themselves. I HIGHLY suggest following it as it will get you about 90% of the way there with just a little time.

My own personal experiance says up the SPP to 1.55 for stability and expect your Core to be around 1.45-1.5v.

Well thanks Lazaredz for the guide. Look at my results. I'm going to lower my
clocks a bit due to temperature. I'm going to lapp my Heatsink to drop a couple of degrees.





3.62Ghz @ 1.4v (403x9). Now I'm also going to try and run my memory at 1:1.

62 and 53c? Thats a bit of a difference.

Have your prime95 it to see how high the temperatures really go under a full load?

Do you know how to lap the heat sink. If you screw it up, you will end up with higher temperatures.

And I hope you are using more than super pi to test the stability of the overclock.

Well the big difference is because I snapped the screenshot right when the test was done and temperatures started dropping. The temps alway stay within a max difference of 5 degrees on both cores. I ran Prime95 for about half hour to check the temps at full load and the max it reached was 68. As soon as I stopped it the temps drop back down and idle at 50 degrees. I couldn't install two instances of Prime95. So I'm planning on running two instances of Orthos and run it for a couple of hours. And about the heatsink; I was going to use this tutotorial: http://www.driverheaven.net/guides/lappingheatsink/

If you didn't run two instances of Prime, then you didn't get accurate temp readings. Your temps will escalate another 7-10C by running it on both cores.

You have to copy and paste the prime executable to another place on your drive. Put one on your desktop and one on your C drive and then run it from those locations and it should work. Then set affinity to 0 on one core and to 1 on the other.

Thanks Xion. I'll do that right now. What is safe temps to run dual Prime95 and how long should I run it for?

Just download the latest release of Orthos ==> http://sp2004.fre3.com/beta/orthos_exe_20060420.cab It automatically detects dual cores and maxxes them both out. Orthos uses the exact same calculations as p95. Matter fact, the code is identical. Notice in the pic below how both cores are maxxed using only one instance of Orthos.

If you can pass 2 hours of Blend testing with Orthos then you can consider it stable with just about anything you throw at it.

Make sure your heatsink is set right. There should not be that much of a differance between cores.

Use Orthos, its great and easy. Just download, install, and it will run both cores without having to mess with it.

Be sure to WATCH your temps while testing. With TAT, I would worry if it gets above 70C. I believe damage starts around 75C-ish.

How do you know when to increase the SPP voltage? Will incrasing the spp voltage possible make it so the cpu doens't need as much voltage for a given overclock?
