Just been reading this thread, I have the P5Q-E and an E8400 due to arrive on Monday, I have 4GB of this ram http://www.overclockers.co.uk/showp...ame=Corsair 2GB DDR2 XMS2-6400C4 TwinX (2x1GB) - will it limit my overclock? should I buy new stuff?..

It wont limit your overclock at 9.5 multi, you can get 4GHz and you ram will only be overclocked by 50MHz

I think I'll have a go at overclocking my Q6600 tomorrow.

I just have a quick question regarding the DRAM:FSB divider. ON my Previous rig (AMD 64) i had to set a divider for the memory so as the FSB was raised the memory was also raised. Reading this guide theres doesn't seem to be any mention of setting a divider for the ram.

Would i be right in thinking that you set the speed for the ram and the bios will put the correct divider on automatically?

I'm currently at 4.2Ghz 1.424 470*9 and my first core has done the blend test for nearly 8 hours now whilst my second failed at 1 hour 11 mins, any way to stabilize without putting more voltage in or voltage the only way? very annoying how one core can be way more stable than the other :mad:

Willhub, is that 1.424 actual, as read from CPU-Z, or 1.424 set in BIOS?

Mine is doing quite well with the Ultima 90. Still testing, though. I don't want to go over 1.4V.

1.424 actual from CPU-Z

I did memtest to test for errors, early in one test I got 1 errors and thats it..

My ram is only at 940 2.04V 5-5-5-15, stock is 1066 2.0-2.1v 5-5-5-15 O_o

Got the CPU to pass small FTT's at 4gig 1.34V but it fails the ****** blend :mad:

Aw man, that's not fair. How about returning it for RMA?

The settings in the OP gave me a Vista 64 registry error. I had to reinstall the OS to fix it. Anyone else had this problem? I am about to reinstall vista and overclock again... it's a bit of a long process to get the same fail again. Any advice?
