Milo, Re: "Some PIV Performance Anamolies being reported." Tom's Hardware reported the same anomalies. Yes, Tom's 3GHz Pentium 4 used DDR, and the 2.6GHz version used RDRAM, but I didn't expect the 2.6GHz to beat the 3GHz by so much in so many tests. My theory is that overclocking the CPU so high with higher voltages, etc, is causing the thermal throttling to kick in, thus lowering performance. Like the author from your link, while overclocked at 2.4GHz, the processor outperformed itself when overclocked to 2.8GHz. No doubt he had to raise the voltage to get it to the latter frequency, which may have activated certain "hot spots" on the chip. I'd say that this may change the way that overclockers run their chips. It may be that default voltages have to be a requirement. Not that it matters too much for production level chips, though, since they will always run at speeds and voltages far below the throttling threshold. wbmw
