Well good luck!!!

You could be the start of the next big craze of ocing around these parts...


What mobo and cooling system will you be using???

yeah let us know how high you can overclock it
i'm curious about how far it will go on default voltage

good luck

I am also curious about which cooling solution you will be using since the Prescott runs as hot as a $2.00 pistol... :)

I'll be using water. Hopefully I can keep it to a light boil!!

Here is a thread with some 2.8E OC'ing action.... The guy quickly swapped over to his Vapochill after fry...err.. trying aircooling.. ;)

tell me how hot that overclocked prescott keeps you during these cold winter days. careful not to start a fire now :)

This cpu burst into flames setting Tibben, my 6 month old kitten, on fire. I have filed a complaint with PETA. Apparently, Intels side venture is Pride Dog food. Myself and the good people over at PETA believe the Prescott is designed to specifically kill felines.

I will keep Anandtech updated on this matter.

You ppl and your temp jokes are not really funny....

Many ppl for years with late series tbirds and even some palominos and such have seen reported temps in the 60's for load for some time....The prescott is not any warmer then that for temps. It is a warm chip but hardly will heat your room in winter...


I have my p4 down below running FH for 3 -1/2 weeks straight now with load temps in the 58-61c range the whole time. I have great case cooling as my temp is only 2c higher then room temp and yet the heat from the exhaust fans in the back is not that warm. My room is stays quite constant as the rest of the downstairs at around 73-75 (around 38-50f outside the last 3-4 weeks).

i have a 2.8E on the way for my other "work" rig and to be honest with you am worried reading what's going around the heat issue.

The reason that Tbirds and Palominos ran that hot isn't only because of heat dissipation; the ineffective retail cooler included by AMD also played a role. According to sandpile.org, the hottest AMD chip ever was the 1400mhz Tbird at 65 Watts maximum power.

The Prescott is in a different league. Here are some power dissipation numbers for a prescott vs northwood system, each @ 3.2ghz:

Link

Power dissipation, idle/load (entire system)

Northwood 3.2ghz - 125W/179W
Prescott 3.2ghz - 165W/248W

According to Intel, the 3.2ghz Prescott dissipates 11W more heat then the northwood, 103W vs 92W. Its obvious though that the Prescott is a much hotter chip. 40W more at idle, 69W more at load! That is a lot of heat, and yes, that will warm up your case and your room.

Well you always should be, but unless you are going to be overclocking or using a retail hsf I wouldn't doubt that it wont run stable and reliable at defualt......

The one site I saw test the retail hsf showed some terrible results, but since I don't think it was a boxed retail unit none of us really knows if Intel is going to package something better in there....So....Looks like mostly OEM chips and ppl use their own cooling solution....

I say need copper connection and a 80 to 92mm fan capable of at least 30-40cfm and upwards.....Also need good case cooling...



For OCing I am not impressed of yet and would not touch one with my Abit mobo.....I will wait to see if newer stepping arrive wit better results or if the socket 755 change will help curve some of the power leakage that is resulting in so much heat on this chip that too a .2v decrease in vcore.


I personally would not recommend one for ocing and since it appears they are slower then northwoods due to the pipeline stage increase I don't even see the reason to recommend one at stock with the current speeds...

Well i guess some ppl will kill me but i sold the P4 2.6C that will be replaced by the new 2.8E...

I hoped i could make at least mild ocing with the 2.8E but i guess i'll wait for an adequat cooling solution..or make another DIY watercooling setup.

another solution is to "sell" the intel system to my sis (she's into design stuff) and wait for a a64 939?
advice plz :)

Well..... (From This 2.8E OC'ing Article)

The IC7-MAX3 did do something that we have never seen before. If you have noticed, we have used square blocks of plastic foam to elevate our boards for years now while we are testing them. The IC7-MAX3 got so hot that it actually melted the plastic block into a liquid form.

The one thing that bothers me most that we have yet to see and will not be seeing for a while is the toll that will be taken on these motherboards by having to deal with all of this heat. It was not uncommon for us to see capacitors at 235F. That is certainly enough to burn you quite quickly. How are those capacitors and other motherboard components going to react to being baked for days at a time...or better yet, months at a time. I have a gut feeling that we are going to see a lot of Prescott related failures on the current motherboards that are in the market even if they are "Prescott Ready."

Initial impressions
It's HOT
Running at 3.5GHz 53C idle 62 load on WATER.
This is one hot cpu.
Runs great though

what voltage?? what thermal compound?? I'd tighten the nuts on the waterblock studs a little and see if the temps come down. I've had 6 -8C higher temps when I didn't put enough preload on the springs.

edit: I just noticed you are using a maze 4 block. you may want to consider a RBX or WhiteWater. Both of those blocks have the inlet right above the CPU die to dissipate heat better. Plumbing is a pain, but worth the lower temps.

Voltage is 1.4625
Compound is AS3
I'll try the springs but I think they are tight.

I have a second 2.8 coming tomorrow and supposedly a 3.2e around the 20th, I'll keep you guys informed.
