    Default Rate my first OC

    I've been browsing over clocking for about a week now, and toying with it on my machine, I've gotten all sorts of weird errors at different speeds. Finally a thread on this forum made something click so I decided to knock it back down to stock and do it properly. I was hoping for comments on my methods and tips for getting to my goal (4ghz) as well as help with memory, which seems to give me the most problems.

    This is my first real attempt at OCing.

    So without more chatter:

    Core 2 Duo E8400 (3.0Ghz)
    EVGA nForce 750i FTW
    Xion Real Power 800 Watt
    Coolermaster V8
    2GB Corsair DDR2 8500 C5D (Running PC2-6400 400mhz)

    I decided to leave the memory alone as it caused me lots of trouble the last few days. I'm aiming for a stable 4.0 Ghz overclock (1Ii've read the E8400 take OCing like a champ, seen CPU-z of it going at 4.5-4.7)

    So I started by unlinking the RAM, and then setting all my BIOS settings to manual and turning them to the settings auto had inflicted upon them before being removed. System was running fine. Ran a few benchmarks, then got back into the BIOS and turned the multiplier on my processor down to x6 to push the FSB.

    The FSB cooperated very well and pushed to 450Mhz without any extra power. 450 Mhz would be more then enough to run the Processor at 4ghz with a 9x multiplier so I didn't bother pushing further. I set the multiplier back to 9x and went to work.

    I've read that the E8400 could eaisly pull off 3.6 on stock power and cooling so I set the FSB to 1600 (From 1333) and turned her on. BSOD, bad start. I bumped it back down to 1500 and it booted fine, started up by increments of 20 until I got to 1570 without a voltage boost. (1580 BSOD). I upped the voltage one notch to 1.23125 and kept going, ill shorten the rest of the steps below (even though it will be long). I got into a habit of using programs errors or BSOD's to measure how much voltage I needed but kept going up only a notch each failure, The worst of the failure's resulted in BSOD, the lesser ones would result in things like Skype or my Z-board drivers failing, and if all that worked I attempted to fire up CoD 4 which would usually BSOD it again and then the next voltage setting would land it working in good order.

    So thats where I'm sitting right now, mostly stable at 3.8Ghz with 1.36875V, Although for some reason Skype still crashes every few minutes (only when the webcam is on), Suggestions?

    I have a few questions that go along with this run, First off, why did my RAM speed drop slightly? It was set in the BIOS to 800 Mhz, and Cpu-z reports it at 396.1 now, the BIOS agrees it did drop to 790 something.

    Any suggestions for getting to 4ghz? Any suggestions for stabilizing Skype? I also would like some tips on stress testing programs, like Prime95? I downloaded it but I dont really understand how it works or what it's trying to tell me it's doing.

    Also is anyone familiar with the type of RAM I'm using, it seems to be very troublesome and I was wondering what anyone else has squeezed out of it. It should be able to run up to 533 with little hasstle according to Spec's and It would be nice to bump it up a bit.

    Here are some CPUZ- shots



    Anything Offered will help, like I said, first attempt at over clocking, I've got a long way to go.

    Edit: Just noticed the Powersaving thing on the intel chip has it cut down to x6 right now, Oh well, it moves up to x9 when something heavy is being done.

    One more notch on the vCore seems to have brought skype back into line as well. Off to bed!

    With the ram , try increasing the voltage. For instance for 533 set it to 2.2V.
