Some fun w/an unlocked 3.4e Prescott

[FelixDeCat]

Unlocked 3.40ghz ES 1mb Prescott, multipliers available are 14 through 17. Unfortunately this board wont run any higher than 285 fsb (MSI Neo2 i865) on any chip Ive tried on this board, regardless of cpu or vdimm voltage. Max stable fsb on any chip (from 2.4c up, etc) appears to be 280fsb.

Ok heres the chip

And heres a few results (Sandra):

(default settings and voltage, 17x200mhz) 800fsb

CPU Arithmetic Drystone: 10332
CPU Multimedia Benchmark: 26962
Memory Bandwidth: 4872 66% effeciency 400mhz data rate, no PAT

CPUz, all default settings - caught on a small downdraft

(overclocked settings, 1.50v, 14x280mhz) 1120fsb

CPU Arithmetic Drystone: 10675
CPU Multimedia Benchmark: 27763
Memory Bandwidth: 5883 84% effeciency 440mhz data rate, no PAT (a 1000+ increase!)

CPUz, overclocked

SP94 cooling, 92mm 3500rpm Thermaltake fan, Artic Silver.

How do you know it's unlocked?

I know nada about the "E" (Prescott?) P4's....except they run hot as hell, but are supposed to scale well.

What mobo/ram?

 

[FelixDeCat]

Some results available.

Ho_Lee_Crap! That's one fast CPU you've got there, my friend! What memory are you running?

Im :heart:'n it. And only $250!

Im running 2x512 Kingston HyperX 4000 in dual channel (1GB).

Can we please dispense with the idea that Prescotts run "hot as hell"?

They are only a little warmer than Northwoods.

He didn't even say what temps he was running and you're asking for us to dismiss the fact that most Prescotts run 10C + hotter in many instances!

Prescotts do run hot as hell. That is a fact. What is also a fact is that they still overclock well despite this fact.

Nonetheless, unless I got a 3.2/3.4ES like this, I'd stick with a Northwood. I don't need a 50% longer pipeline and more heat for my room, thank you .

 

[LTC8K6]

Like I said, they are only a little warmer than Northwoods. Nothing that a good HSF can't handle easily. Certainly not hot as hell, or anywhere near it.

Where is the evidence that they are "hot as hell"? Where is the evidence that most Prescotts run 10C+ hotter in many instances?

I have seen many posters here with excellent overclocks of Prescotts on air, so how hot can it really be?

I care not a whit which companies you choose to give your money to, btw.

yep.
you forgot to mention that Prescotts are slower, clock for clock too.

It was implied with the pipeline comment. But I do agree, clock for clock they are slower.

What do you mean - what company I choose to give my money to? You mean Intel or Intel? Yes, I'm biased against Intel's chips because I like Intel chips better...

 

[LTC8K6]

Hmmmmm....I thought there were one or two areas where Prescott was faster?

IIRC it is faster than NW for some media encoding.

Sure there are some reports. I never doubted that.

There are some reports that contradict that as well.

Show me one from a respective hardware site please?

 

[LTC8K6]

Well, one or two reports doesn't prove the idea that Prescotts are hot as hell, or that most Prescotts are more than 10 degrees C hotter than a Northwood.

I have agreed that they are hotter than Northwoods, but I just don't think it is the big deal that some posters are making of it.

I am basing my info on reports from posters here, and reports of overclocks on air. If they were really hot as hell, or way hotter than Northwoods, we'd have seen it with folks unable to cool the Prescotts or unable to overclock much on air, wouldn't we? Prescotts seem to overclock as good or better than Northwoods on air.

It could also be that the early stepping Prescotts were hotter than what people are purchasing now.

I am scared to imagine what happens to Prescott when we close the system case?

I find it difficult to accept an article with such a line in it. As if people with Prescotts wouldn't even be able to close their cases. We would surely know of this problem by now.

I suspect some sort of error. Perhaps not reading Prescott's diode correctly?

If Prescott is such a flamethrower, it just seems like we would have had all sorts of complaints by now.

Here is a line from the Legit Reviews article about Prescott temps:

To be blunt, and to the point, forget about overclocking or even running the Prescott in an un-air conditioned room with the heat sink that comes with the boxed retail version (unless Intel Improves it).

It just seems like this hasn't turned out to be true at all. Forget about even running it?

Okay......

My 3.2e runs quite a bit hotter than my 2.6c northwood. RIght now, its at 53.5c, and under full load it gets up to about 67c. The good news is that it doesn't get much hotter with its at 4Ghz.

 

[MichaelZ]

well prescotts were meant to run high frequencies, i wouldn't worry much about the temps too much if you got good cooling. nice buy.

 

[dennisjai215]

clock for clock northwood > prescotts 3.5ghz and under.. once u get a prescott to 3.6 area clock for clock they beat northwood and there was benchmarks for that but im too lazy to find them

I can attest to the "hotness" of the Prescott. I have a 2.8E OC'ed to 3.4GHZ and it warms the part of my room where my mid-tower is pretty quickly.

 

[LTC8K6]

Yes, but you did bother to run it.

 

[Gamingphreek]

Unlocked Intel processor huh. Well that is awesome luck. Now do this get some awesome cooling probably better than water so were talking like phase change and OC the hell out of that chip. It will be very interesting to see how high you can get an unlock Intel chip.

Nice buy!!!!

I Kinda agree...good case cooling and good CPU cooler and you'll be fine.
only thing that I love about the heat these things put off is, you won't hear Intel fanbois claiming they won't buy AMD cause they run too hot, that's for sure

 

[Zebo]

I don't understand.

You overclcoked from 3.4 to 4.0 or about 17%

But your CPU scores only went up an average of 3%???

You mem scores are in inline though....
