If you are looking to overclock the chip, in the range of say 4.0GHZ or higher, you will most likely see the Prescott start to be faster. In the future you may also see some advantages of the implementation of SSE3, but most likely not anytime soon. Right now the Prescott in it's current state is slow, extremely hot, and not worth the trouble.

They want to document how much heat it puts out, so they can get it banned for lack of energy conservation ?

thank you all for confirming that....

was wondering myself. every oc review i saw put the 3.0gb range processors at or below their northwood conterpart. that's enough reason to scrap it, without the overheating problem. price is good, but the cost of building around it is what's gonna break you.

1. While it is generally slower, there /are/ some benchmarks where it beats the Northwoods. If those apps are all you want use, then get one.
2. SSE3 support will probably speed it up a bit later on.
3. You want LGA755, in which case Northwood is a no go.

Other than that, no, not really. Northwoods seem pretty much superior.

I heard about the heat issues... my temps never go abve 55c
stock fan no case fan...only cpu and video fans running

I heard it was slower...in lifemapper I run 2 instances all the time, it rocks,virus scans,no problems games are smooth and fast.

I am running a 3.2E and an asus p4p800 - E deluxe,2 Raptors in raid 0,an ati 9700 pro,512 mb corsair xms pc 3700 ram.

I am happy with it...but my start up temps range from 34c to 39c depending on the temp in my room.
idle never goes above 44c (even after gaming)(remember this runs 2 (@ 50 % each) 100% cpu intensive tasks in the background 24/7)


ymmv

I would say it's a toss up. Get whichever one is cheaper.

There is also no valid reason not to buy one, as far as I can see. I remember several posters overclocking 2.8E's quite a lot with the stock HSF.

Since the Northwood is basically history, you might as well get a Prescott.

Or get an A64. :D

I just built one with 3.0E with the stock heatsink and fan. I'm aware that I might regret some day for not following community wisdom.

But, so far I haven't experienced much problems as I'm running at stock speed. However, the heat problem was really scary. Since my ABit IC7-G gave me temperature readings in the range of 58-73C. However, I attached a thermister to the heat sink, very close to the bottom. The readings from the thermister is usually 20C lower. I checked ABit forum and found the IC7-G mobo temp sensor reading is screwed up and usually 10C higher than actual number. It left me wonder how hot exactly the CPU was. Anandtech testing showed the load temperature of 3.2E as 50C. I was so dissapointed to see mine run at 10+C higher.

A more important question I'd like to ask is what's the temperature range for CPU to run reliably.

One off topic question about the case - Thermaltake Lanfire XAser III: I found all the four fans on the case are sucking in air and I didn't find a way to reverse any of them. Were they supposed to be like that? I think having two of them sucking in air and two of them blowing out air could really increase the air flow. Anyone has experience with that, please share.

While Abit boards to tend do read temps a bit high, your heatsink temp reading isn't really relevant.. you want the temp of the chip (or as close to it as possible) - not the hsf. And while Prescotts do seem to be ok at ~70c, they can easily run hotter, and will definitely do so if you OC. That can heat up a small room if you have it running for a bit.

i didn't mention that mine is overclocked to 3550 didn't i with a max load temp of 59c stock cooler...cpufan video fan ,nothing else?


maybe i just got lucky then?
