My 2500+ xp-m is running at 2.54Ghz @37c
Well I must be doing real well, As My 2500+ xp-m is running at 2.54Ghz @37c so far today (1.95vcore) and the Ram I'm using is OCZ PC4200EL 512Mb DC (2x256Mb) ram(2.90vdimm voltage), I have an sp-97 with a 92mm Tornado which helps, I may need to use AS2 under the northbridge to go faster though, Not bad for air cooling. And to think this cpu only cost Me $95.00 and I was able to sell My old 3000+ cpu on ebay for the same amount too, So in the end all I had to pay for was for the ebay and paypal fees for My old cpu.
Edit: Oh and I have a DFI NFII Lanparty Ultra B motherboard with the Stock Bios that I run this on, I have an SLK-948U mounting plate as the Original mounting plate could damage the DFI Ultra Infinity and the Ultra B that I have now, dust not withstanding that is and I have to clean out the hsf every month around here, As I have a Cat.
