So I recieved my new rig last tues and got it up and running.  Once I got all the software installed and games and such I wanted to over clock my CPU.

Specs----

CPU: AMD 5000 Black Edition(Stock Info= 2.6GHz @ v1.35)
RAM: Corsair DDR2 800 4-4-4-12 T1
Video: MSI 8800GT 660/950

With this black edition CPU I can change the multiplier to overclock it.  I locked the PCI-E slot at 100MHz. Then I did it one multiplier at a time to get to 3.2GHz which will NOT boot into windows.  It gives me BSOD then reboots.  This is at voltages up to .25 over stock I will not go any high for fear of frying my CPU.  I got to 3.1 @ 1.5(+.15 Volts).  But when I run tests it crash my computer instantly.  I bumped it down to 3GHz at 1.45v and its 100% stable.  I just don't get it.  Some people are able to get it as high as 3.6GHz w/o issues but I can't even get it to 3.2 without BSOD reboot.    Is there anything I am missing here that would cause these reboots?

Thanks for any help!

What is your multiplier at? I have an unlocked CPU too, yet changing the multiplier only made it harder to overclock.

Sorry stock Multiplier is at 13.  I can go up to 15 stable and 15.5 bootable.

I havnt done any over clocking on an X2 system yet although ive read abit about it as i planned on overclocking, and from what ive read they have to reduce the multiplyer and increase the HTT in order to overclock otherwise the FSB is to high which causes system instability.. this was for the 4400 x2 tho so it could be different for ur cpu

The memory frequency is determined as follows:

(HTT speed) x (cpu multiplier) / (memory divisor) = memory clock

... And the DDR2-800 memory (by definition, since it is Double Data Rate) actually uses a 400 MHz clock.

Therefore, to reach the 333 x 9 final overclocked speed, the following steps were taken:

- Set the FSB (HTT) speed to 333MHz
- Configure the HTT multipliers to 3x
- Raise HTT voltages to 1.25V
- Raise Vcore to 1.5V
- Set the memory speed to "DDR2-533"
- Set the DDR2 memory voltage to 2.2V (as specified for the modules)
- Set the memory timing to 4-4-4-12/2T (as 1T was not stable at that speed)

Thanks for the help but I will probably get more performace as is than doing all that.  Especialy since your lowering memory performance for only a 200MHz increase.  I think I will stick with my 3.0GHz stable and update my bios on a regular bases to see if that helps.  Thanks though
