You need to download CPU-Z 1.33.

In the "technology" window you'd either see 130nm (for Northwood) or 90nm (for Prescott. Then you'll know which oen you have.

Temps vary, Northwoods generally were faster and better than Prescott socket 478 and alro ran cooler tha. Northwood should see somewhere from 27-31c idle and 50c load with the stock cooler but Prescotts get really hot, I think 60-65c at full load and that's when a 3rd party cooler is needed.

One of the reasons why I avoided Socket 478 Prescotts, ran hot but the LGA 6xx Prescotts much better.

Hmph, you COULD say that since Northies run cooler and can take higher voltage.

Northwoods run cooler and there much faster because of there shorter stage process Northwoods have 21 and prescotts have 30.
post #8 of 31
The difference in Northwoods and Prescotts is that the Northwoods have a 20 stage pipeline compated to Prescott's 31 stage. @ 3.2ghz Northwood is faster than a 3.2ghz Prescott and the Prescotts start shining @ 3.8ghz and above..........

Which most Prescotts can overclock to, thanks to its 31 long pipelines they can achive those speeds either if you get a 3.0ghz or 3.2ghz Prescott, but chances of reaching those speeds (3.8ghz-4.0ghz) are more likely with an LGA due to the advantages of DDR2 high frequencies.

Heast-sink/fans play a big role too, unfortunately the 90nm Prescott LGA still run a little bit hot so a 3rd party HSF will definitely help. But not all HSF are created equal, I always thought that a Pure copper heat-sink/fan was the way to go but found out recently that the heat-pipe design HSF is way better. My Tuniq Tower 120 keeps my CPU @ 33c idle and 44c under full load, compared to my older HSF which did 40c idle and 55c loaded.

Got a Northy 2.4D to 3.15 on a Scythe Bat at 44°C load. I always try to keep the temp under 53°C. Sudden Northwood Death Syndrome is a bummer. But Prescotts run a bit warmer from what I understand.
