CRAZY!! 21x Prescott ???????!!!!!!!!!!!

[charlie]

Yup,
Newegg has ANOTHER CRAZY Prescott. It's the new 2.8A Prescott core, 533mHz FSB Retail CPU for $170.
With 21x MULTI
Hmmm.....
This could be an INCREDIBLE 1:1 CPU on phase change/DI/LN2
21 x 225=4725
21 x 250=5250

LOL!
Imagine LN2, 21 x 250, 1:1, 2-2-2-5, 5250mHz....GREAT Spi scores!!!! WR I'm sure...

Now for mortals, this cpu'd SUCK! 21 x 175-180 would be about it for Watercooling and about 210-220 on phase change.
What I'd REALLY like is a 2.8A Prescott ES chip with 14x-21x available!!! That'd be SWEEEETT.
Where's that spec code finder....?? maybe this is D0 stepping :D

[charlie]

no such luck, a C0, 89w CPU

[althes]

this will get interesting

[Shane5578]

the highest multi is 26 from a 2.6a

theres a risk it won't run 200fsb even with phasechange. lol:D

[craig588]

but the 2.6A isnt a prescott.

[Peen]

you would need 4.2ghz just to get 200fsb :eek:

Too bad at that speed they STILL wouldn't 3D worth a sh*t.

[Peen]

Kanavit! this is for you high multi!

on a side note, $125 for brand new retail 2.4A :slobber:

[charlie]

I would THINK about getting one, but after torture with DI I'd want to use it as a 24/7 CPU, unfortunately aircooled it would probably SUCK! Like 185fsb = 3885mHz although you could use the 3:4 memory divider to boost DDR speed to 247fsb.
OTOH, you could probably run crappy ch5 at 2-2-2-5 at like 180...

C

[Peen]

well, they are $170 bucks which is a rip off IMO. $125 for 2.4A seems much much better

2.4A - $125
2.8A - $170
2.8C - $179

im sure they will drop to maybe about 150?

would be interesting to see what it would to though! too bad its probly a C0 though :(

C

problem is you probly wouldnt get the boost because the CPU isnt running at that speed? not sure though

[afireinside]

Throw it in your every day water rig when your done with it... 200 fsb might be possible :p:

[charlie]

It would help :D remember the 845PE chipset, and running the OLD 2.53, 2.66 and 2.8 and 3.06's we'd all use the 4:5 or 3:4 dividers to boost DDR speeds and it HELPED. Same here... just not as much as running sync @ 260

[Tedinde]

ouch very hot.

I love my 28X 2.8 celeron for killing memory bandwidth. 3.6ghz in a single channel shuttle rig!!!

i think my current 2.8b is 21x too. no HT on the prescott, hmm.

[Peen]

would be a downgrade man. save the dough

[charlie]

Anyone speak Russian?
2.8A @ 3.6gHz on boxed cooler @ 1.41V
http://www.overclockers.ru/news/newsitem.shtml?category=1&id=1075142036

[charlie]

Just for reference sake, most 2.4A go about 3.3 or 3.4 on air with stock voltage....

That's good :D

[Kanavit]

i think the 2.4A prescott is better, since it has higher multiplyer 24x. Macci used this chip to set 3dmark03 record. but, the 2.8A prescott could be better overlocker possibly.

[charlie]

no, the 2.4A prescott is an 18x multiplier, 18 x 133 = 2394
if Macci had been using the 2.8A, he could have kept the DDR @ 1:1 at the same CPU speed.... very good for performance and would have netted better times :D

C

[Kanavit]

your right Charlie, i was thinking about the 2.4a northwood. the prescott 2.4a has 18x multi, so the 2.8a prescott should be better.

[Tedinde]

http://www.newegg.com/app/viewproduct.asp?description=19-116-178&DEPA=0

$125 is a killer price. a few refurbs there for $109, I ordered one. What the hell. It's make a nice Folder when im done messing with it.

I KNEW it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
With serious cooling this thing's the bomb!!! 24m SuperPi, that's just wrong...
Wooo Hoooooooooo!!
Evil, it is.... a $170 processor that is fit to be called "The world's FASTEST processor"

one more time! this time for the sake of ART!!!!

[enzoR]

LOL Charlie :D ;)

[JWB]

A shame they do not run 3d mark:( or else they would be top of orb even lowered to around 5ghz 3d stable maybe? So you getting one charlie?

[cpulloverclock]

I say LOL

[JWB]

Whats wrong with that? are the prescots slower at 3d mark? if so the extra 500mhz (around) they could run it at would make the difference up and more, plus he has an EE at 5326 also:D

http://www.vr-zone.com/ocdb/data.php?id=40&intel_or_amd=intel

[charlie]

Maybe Prescott's are not very good at 3D, but with 5ghz++ it couldn't be "bad". And yes, I ordered one last night....I will have it Tues.

C

[Kanavit]

is that the 1mb Super_PI? and isn't the japanese version is faster than the english version?

[sierra_bound]

This is memesama's website. Link (http://members.jcom.home.ne.jp/3233730401/index.htm). Ignore the picture on the front page. Just click on some of the items to the left.

I'm not aware of a faster Japanese version of SuperPi. I believe the original program was developed at the University of Tokyo back in the 1990's. There are a number of variants including of course PiFast. Pi programs (http://www.myownlittleworld.com/pi/otherpi.html)

[twiggy]

Hahahaha! charlie you crack me up.:hehe: Good luck with the new chip.:toast:

[charlie]

Great website... the boy is sick. Sick in a good way of course :D Kinda' like a Japanese version of Macci ;)
Two guys that have overclocked every/anything they've EVER owned! Wouldn't be surprised in his house that the light bulbs burn out after 1 week and the cat lived to be 2 yrs. old... the tv remote control changes channels at 25Hz, and the refrigerator needs daily de-icing :D

Bump for "THE WORLD'S FASTEST CPU"

wOOOOOOOOOOOOOOOOhOOOOOOOOOOOOOOO!!!!
Here in my house tommorrow!!!! Unfortunately on DI I'll be LUCKY to hit 5gHz!!!!

[cold_ice]

Nice
Hope we see some results soon
Maybe I'll go for a 2.8a too

apart from the complete overreacting, nice results :eek:

lets get cracking.

4009.3

26C Ambient, Air cooled and 56C BIOS

At only 1.5v
Need to rig up a writeable drive, be back later...

:D

evil, nasty thing. I love it.

im confused, doesnt Prescott varies its volts on the fly in windows n stuff? i want one of these, but my board locks you out of vcore adjustments :mad:

looks like intel has ironed out the thermal problems with new stepping. very nice , 4ghz on air and only 56c bios. can't wait to see some super_pi benches.

this is still C1 kanavit

[charlie]

The preview of a 4.2gHz Prescott?

21 x 200 = 4200

1:1, 2-2-2-5

[charlie]

And starting to build up a head of speed...

21 x 210 = 4410

1:1, 2-2-2-5

[gouda96]

If only it performed as good as a 4.2c in 3d apps :toast:

[craig588]

Have you moved on to dry ice, or are you pulling this on air?

[charlie]

Oh yeah....I'm on DI now...

12 x 219 = 4602

1:1, 2-2-2-5

[Kunaak]

anything more then screen shots yet?

[charlie]

Not yet...
Trying to find the ceiling first, doesn't look like I can take 5gHz with DI, though.... :(
After finding ceiling I'll run some Spi

C

[Kunaak]

how about hexus Pifast?

about time we got your name on that list ;)

[novagamer]

What was the max on air Charlie? j/w :) great chip!

[charlie]

I just can't get good benching results...my DI rig just doesn't cut it... I need to build a new one! Or get a Cascade :D

[charlie]

Pifast

[charlie]

And max for the night, :(

[charlie]

I still had fun, though :D
How could an evening of OC be bad??

[Kanavit]

Charlie, u just motivated me to get a prescott now.

[JWB]

Still nice results Charlie although would have liked to see that you could have gone higherm, but thats luck of the draw I guess and memesama does use LN2:rolleyes:

BTW Charlie where do you get your dry ice equipment from like the tube thingy etc?

Good luck for further benching.

jwb

[ctgilles]

Looks to be better and better Charlie :toast:
Pressies are fun :D
Too bad you couldn't take 5G with your CPU and DI :(

[charlie]

Now the problem is....
...if I keep this chip and stick it in my desktop water rig, it'll probably run 21 x 200 = 4200 but that performace will suck for a desktop rig, low mem b/w and no H/T. In fact probably be outperformed on the desktop by a 2.8C, or even 2.4C. Maybe eBay it or return to Newegg??

kinda wierd that they are making prescott in both 800 and 533 fsb models or is 400 fsb? im all confused??? so intel makes this prescott in diff models? i gues this one here has less fsb and no HT? but the core is still a prescott? damm this chip ocs great just too bad its castrated? so the 800 fsb version should oc just as good as the A series i take it?

thx perc.,

[Peen]

it does 4.2g on water? :slobber:

[charlie]

I'm SURE it will... it did 4009 EASY on AIR...

C

[Peen]

what did it do stock volts and stock cooling? i want one of these

[charlie]

I'll slap on the Intel Retail Boxed cooler and test for stability @ stock voltage later tonight :D before I put it under water.


C

[Peen]

cool :D

[gouda96]

Not as cool as DI though :D

[ctgilles]

Charlie, return it to NewEgg if you must. But remember the great times you had with it... *nostalgic* :D

[althes]

It was a great one night stand.

does overclocking make it better or worse? of course if your overclocking the clock speed is faster. overclocking your 2.4C to 3ghz plus would be faster lol. same with getting a 3.0E and overclocking it to like 3.6ghz

[charlie]

:thumbsup:

[IvanAndreevich]

Send it back :) Find a M0 which will do the same... that would be ownage.

So what was the MAX stable with water?

[charlie]

Today I'm priming at 1.43v, 3800mHz.... loaded at 54C

C

[IvanAndreevich]

charlie
So your initial approximation of 4.2 Ghz was not possible with watercooling?

[Tedinde]

I got a 2.4a prescott. It maxes out @ 3.6 on air. Not bad for the $109 I paid @ newegg.

I CAN get screenies and Sandra benchies at 4.2gHz on WC, but for 24/7 use, P95 approved, no :(

[IvanAndreevich]

charlie
Have you tried bumping vcore yet? What's the max you were able to get under Prime Small FFT's load with the 3.8 Ghz and stock vcore?

[charlie]

stock Vcore on the older P95, about 3750, maybe 3730...
