Q6600 G0 @ Default = Fail - Scooby snacks for someone to help me

I'd also do the BIOS update using the good old floppy disk in DOS method rather then the online in Windows method suggested above.
 
Why? It is still flashing the EPROM! If you use the floppy method and there is a problem you've killed the PC! With the windows method if there is a problem you can re-flash the EPROM as long as windows is not reset! It does exactly the same thing just safer!

ChrisB - you have exactly same as me (what memory you got?)

When you first started your pc did you leave everything AUTO and not up the memory and cpu volts? If so did you try running prime95 and did it error??????

What bios revision you running? What memory timings voltage you running?
 
Aye, that I did.
The timings on auto though.
Funnily vista installed even though the volts were low.
Once that was on I had a quick check on here and read about the volts, fixed them, then ran prime with everest monitoring the temps.
 
hmmmmmm maybe thats my problem then - im still running my memory at 1.8V (although running at stock timings 5 5 5 15)

It says in manual it should be 2.1 for 4 4 4 12 - but I never changed the timings therefore didnt change the volts :D
 
Yup, vdimm is probably the first thing to check if it's failing Prime at stock, purely because different DDR2 brands vary a fair bit in their voltage specifications. You probably don't need the *full* 2.1 for Prime stable @ stock, but you have to experiment:)
 
Okay tried upping my memory voltate to +0.2 and Prime95 failed after 80minutes again. GRRRRR!

I have now decided to do the following:-

I have updated the bios to F4 (seemed to go okay)
Reset to optimal settings
Changed the memory voltage to +0.3
Changed memory settings to 4 4 4 12
Changed cpu voltage to 1.3
Changed cpu/ram ratio to 2
C1E TM2 and EIST disabled
Changed bus speed to 300

So now my CPU is at 2700......

How does this sound?

I am currently running PRIME95 again (been running 20mins) - will post what happens.......

Thanks!!!!!!!!!
 
I would change memory voltage to +0.3 but leave memory settings to SPD or Auto, that way you remove the memory from the equation as the bios will use the safest settings. Then test, its no point testing your CPU overclock and your memory overclock at the same time.
 
eeeeeeeek........... if it fails I will do as commanded :P

Its still running fine at the moment fingers crossed!!!!!!!!!!!

I do need to run memory 1:1 with the cpu tho? It was 3:4 before or something
 
No you don't need to run it 1:1 with the CPU, Core2Quad and Duo doesn't really benefit that much from having the memory running synchronously with the CPU, not like the AMD64'd do. You get some benefit in benchmarks like Sandra but not really that much in the real world. That ratio is how you will overclock the memory. Its based on a ratio of the FSB to get the final memory speed.
