Madness....

Hi,

I overclocked my pc as per the settings in my sig, it was prime stable for 15hrs +

Now I just realised my RAM wasn't running to the overclock so I went into the BIOS and noticed it had changed to run slower then what I found the max overclocking to be whilst testing...

As I have a DFI board I simply reloaded the overclocking bios and manually checked all settings were correct..Which they were, once I had reloaded the overclocking bios....

When I booted I couldnt even get into windows...Yet it primed stable for 15hrs+ I ran 2 instances of prime95 and it was working perfectly fine before..

Im thinking my Overclock is no longer stable? what do you think? How can it run for 3 - 4 weeks stable then stop overnight?

Please advise...

Thanks in advance..

Don't you love it when it does that! I take it you've tried a couple of resets to see if it's just a cold-boot issue?

Ovbiously there are several environmental factors that can affect your overclock - is the ambient temperature higher? Has your airflow changed? Is anything else in your rig different? Did you sacrifice the correct number of chickens in the server room by the last full moon? Any one of these things could make a difference (especially the last one )

Since you identified your memory as having been "at the wrong setting" I'd suggest giong back into the bios (reset it manually if you can't get in) and dropping the divider right down to take the RAM out of the equation and see if that works - remember our Mobo has Memtest built into the bios - always worth leaving it running for a couple of tests before trying to get into windows - confirms that your ram likes the overclock!

Otherwise you'll have to start again I'm afraid - drop the clock right back, work out what your RAM clocks to (memtest, memtest, memtest!), then your chip, and then the 2 together - painful I know, but if a little tinkering won't do it, you will have to start again - just too many variables!

EDIT: Just realised - it falls over getting into windows, which is actually a good thing, it means you're close! Run memtest and see if it errors, if it's clean, back off the overclock in 5Mhz jumps and prime when you get in - might save some pain

Didnt change anything , I just noticed when I rebooted the clock count was slower than it passed all tests at when I was overclocking...

No changes to airflow, or any of the possibilites you mentioned..

Thing that got me was when I put the RAM back to what it primed at I could not enter windows so the strangest thing was like for weeks on end its fine then suddenly it decided it didnt like it...lol...

Anyway I will drop CPU FSB and see if I can get into windows..

Thanks mate appreciate your time and advice..
