Got some Prescott

I`ve bought this CPU for ~30$.
http://images.people.overclockers.ru/56777.jpg
The man I bought it from said that it isn`t workable so I decided to make a brinket out of it. But before digging a hole in it I decided to test if it is really unworkable. :)
And, guess what, it`s not. Although it is able to start Windows, it is not benchable at default freq.
But, MAN, it is one overclockable CPU.
On stock volts it started Windows at 4275MHz. :eek:
On increased voltage - 4723MHz ! :eek: :eek:
But it`s not even the best thing about it.
IT HAS UNLOCKED MULTIPLIER ! :eek:

You know, I don`t want to do a brinket out of it anymore ...

Very nice CPU...

ill tell , nice, but its time to try some amd cpus :)

Need something other than CPU-Z shots to make this thread worth while.

Pi, 3d, pifast, ANYTHING... :)

I have tried to run SuperPi 4M at 3000MHz.
Both times the system freezed.
If it not capable of SuperPi it will not definetly run 3DMark or Prime.
It even needs at least two attempts to start Windows.

You'd better say those are suicide shots, then? Nice CPU :)

What a find! Nice clocking :)

Hey, bro, great found there.
Try to play with multiplers and voltages, maybe you'll get some stable freq.
Still funny, this chip can do 4.7Ghz SS, but cant bench even on stock.

Am I the only one here that doesn't know what a "brinket" is? :p:

No.

possibly similar to a trinket?

Anyway tbh just put it under something chilly, get a high SS then make it into a brinkiet or whatever else you got planned. If it can't even run windows without a fight then it is somewhat useless, surely?

Default volts aren't 1.1V for prescott. It's 1.35 I thought.

Can I buy it? :D

nice cpu:D

Holy :banana::banana::banana::banana:!
Amazing CPU
You should definitely play with voltage and clocks, maybe ypu get it stable.
This CPu must be the best DO ever.
What Cooling are you using @4,7Ghz?

Alba

Thats a dam nice chip!, I picked up a second hand 3.2 that will do 4.5 up on ss, i only planned on using it for a folding rig but now its my primary chip gaming chip until I buy the fx60. Nice find mate just shows that some of the older gear can still perform quite will especially at that price. Try and get up some benches though as im sure with a bit of tweaking you should be able to get it stable.

BTW theres a new word on the WIKI ;)

Brinket

As I can remember "brinket" is a thing that you attach for your carkey and carry it around.

Titan Siberia (air cooling)

Hurra ! I finally got is benchable !:)
But it is only benchable @ 2.3GHz :(
But I have added some the Dry Ice and the result is ....
http://images.people.overclockers.ru/56847.png
5371MHz (suicide shot)

System:
MB: ASUS P4C800-E Deluxe
RAM: HyperX3200 FSB:RAM=3:2
PowerSupply: Q-Tec 500W
OS: WinXP SP2

With special thanks to BiZaZ: who has kindly presented me with tube and dry ice

OMG, bro, you need to aware from this CLOWN power supply.
Nice results, and can you run SP2004?

Yeah definately bin that power supply.

BTW what memory you using?

It`s not really THAT bad. I measured it - it`s 411W. (not bad)

are your voltages stable i.e. the p4c is renowned for have a problem with core voltage droop under load or is it voltmodded e.g mine is set to run at 1.6volts but while under continuous load droops to 1.47volts and thats on a pc power & cooling 510W which is a damn good psu (cant be bothered to mod the board as it's usually folding)

It`s true. I set is BIOS 1.7125v and CPU-Z shows that is 1.664v
It`s a problem of a Prescott core: you set one voltage - cpu-z shows the other that is lower.

Its possible that this is part of the stability problem, i've been able to suicide up to over 4.6 but the minute any load is put on the processor the voltage droop on the core causes the machine to hang. In theory, with a droop mod, you could go higher and stay stable. Still a damn good result though.

I can buy a Sl7E4 for 130 Euro, but I am not sure if all Sl7E4 clock so good.
What do you think?
Because it is only a DO, and no EO...

Sry for my English
Alba

I`m not selling it.

Anyway aware from this PSU.

Yes, of course, I also don´t want to buy it, I only would like to know, if you oc freaks think that other SL7E4 overclock so damn good like this one!

Greetz

I don`t think that other SL7E4 will clock this good.

I'd get a new PSU. Q-Tec's or w/e are KNOWN to blow and take hardware with it. C'mon man....

Get an Enermax Noisetaker 420w or somethin for $65. Anything's better... or get a Tagan 2Force 480w. Similar innard's to the OCZ Powerstream 520... for $85 depending on where u buy it.

Sick Prescott you got there :O

Very nice CPU there ... my D0 can do around 3,9Ghz at stock volts on a SP-94 ... load temps are 45C max. But anyway ...

As all the others mentioned get a good quality PSU and do at least the droop mod on your P4C800. Believe me its worth it! ;)

I really feel bad for that CPU, an Extreme overclocking ES.

Who could destroy such CPU!

unlocked precott!!!??? amazing!

hey how did you get the unlocked multis my brother has the same chip and i dont know if its unlocked.

its deffinatly mislabeled, its a really messed up chip.

Engineering Sample

how do you end up with one of those? and will any sl7e4 by unlocked ?

I called the guy I bought it from and he said that he tried to some mod to the chip. He thought that he failed because CPU did not start (for him), so he decided to sell it.
Lucky me !!!

any idea what he tried to do, i got the chance t buy a cpu with the same stepping if not i can jack up my brothers 3.2ghz prescot and see whats going on.

Got some other Prescott.
Now it`s S478 E0 3.0GHz.
It is SuperPi stable @ 4.33GHz. 31.906s - http://www.xtremesystems.org/forums/...0&d=1140773927
Suicide shot: http://valid.x86-secret.com/show_oc?id=74239
All that was done with BOXed cooler + 120mm fan.

Gonna get me some DI... :)

had a 3.0GHz E0 myself...did 4.0GHz prime stable with a Thermalright SP94 cooler. Benched superpi on 4.2GHz. Really nice chips, these E0's:D

Does anybody over here have an idea why the theme about
INTEL PENTIUM4 PRESCOTT is located in AMD forum ?

Comedy! :slap:

That is very nice but wrong Forum.. Mods please move to Intel
