Prescott 2.8Ghz @ 4Ghz on Air, Again
Last response: in CPUs
This might be old news, but... <A HREF="http://www.vr-zone.com/?i=477" target="_new">These news</A> say that Prescotts can be clocked at 4Ghz on air. Apparently, ES samples review sites received may clock worse than actual retail Prescotts. These guys is not at all the first ones to say that prescott can be OCed to 4Ghz on air. From 2.8Ghz, this is a 43% overclock - not bad, eh?
Hopefully, with the improvements the D0 stepping brings along, Prescott might turn out to be a good choice for an OCer... It would be much better, though, if the damned thing had some sort of 64-bit support like x86-64... Come on, Intel, hurry up!![:eek:]( ":eek:")
Debug the damned thing quicker...

I really want to see someone benchmarking it under full load, cause I'm curious if and when clockthrotteling kicks in. Xbit labs showed a northwood started throtteling at 70°C. Prescott at stock speed reaches those temps, so overclocked ones would definately. I suspect throtteling kicks in later on Prescott, but when? its not much use having a 4 GHz overclock if throtteling gives you 3.2 GHz performance...

Wrong. It will still run at 4 GHz according to the BIOS and tools like CPU-ID, and there is no way that I am aware of to determine wether a cpu is throtteling or not, besides benchmarking it.Here is a quote <A HREF="http://www.xbitlabs.com/articles/cpu/display/p4-temp.ht..." target="_new"> from xbit labs:</A>
For example, we overclock a Pentium 4 2.2GHz to 2.8GHz, but don't improve the cooling. In this case the CPU temperature quickly gets above the critical value and Thermal Monitor unleashes Thermal Control Circuit: the CPU starts missing out clock cycles. As a result, the user will see during boot-up and in WCPUid-like programs that the CPU is at 2.8GHz, although the effective performance of the processor may be even lower than that of Pentium 4 2.2GHz.

OK, you were right, I was wrong. Sorry 'bout that... :frown:
(so there would be no way - really - to know if current prescotts are throttling at stock or not?...)

No that I'm aware off, besides benchmarking a watercooled setup against a stock cooler setup. Now, I don't think prescott throttles with a stock cooler under normal circumstances really, that would be absurd, but its quite possible once you start overclocking/overvolting or in less than optimal thermal/airflow circumstances. Soon enough someone will do an article and tell us at what temperature its starts throtteling though, then we'll know...

70c jebus! I thought my amd at 49c under intense load and warm room was a spaceheater. Just imagine 70c!
