Well you should know, that the Prescott D0 has already been seen in Japan, and i'm very sure that chip they've used is the Prescott D0. They've done 4.0Ghz with aircooling stable, i guess they're probably on prometeia to reach 5.3 stably, i don't think they even need to use liquid nitrogen.

Remember Tom did the 5.25Ghz on a northwood.

It would nice the see benchmarks of toms northwood at 5.25 and a presscot at 5ghz to compare.

Oh yeah 40k

Prometeia GT took a Prescott C0 stepping up to 5GHz....D0 + Prommy GT could probably hit 5.5GHz if I had to guess. Then there is LN and dry ice for a 6GHz run. Considering a 2.8A (D0 Scotty) only runs at FSB 257 at 5.4GHz (as seen in the picture)...it could run in sync with the RAM at 6GHz for startling (albeit shortlived) performance.

I'm sure the Scotty would achieve at least parity due to its better scaling. THG's 5.25C was not stable enough to run benchies, however.

I hope the P4 at 5.4Ghz+ won't bottleneck the 6800ultra/X800XT at lower res in games.

I want to see Athlon64 FX57!! AMD at 3.0ghz by default!! JESUS that's gonna BE FAST!! Imagine what you could do with a little prommy.

I'd hope it doesn't bottleneck too much.....but you never know.

I think you meant an FX59 @ 3.0GHz....something we probably won't see this year (only a 2.6GHz A64 4000+ is on the roadmaps for this year (Q4), so I doubt a 3.0GHz FX is in line...maybe the 2.8GHz FX57). Anyway, we probably won't see any major clockspeed advances from AMD until Intel truly gets its act together (Q3 '05 at the soonest, IMO). Scotty D0 should go no further than 4.0GHz as retail, then we might get some FSB increases, but nothing impressive will come out of Intel for awhile now that Tejas was cancelled. And then we will finally see AMD kickup the A64 lines to their maxes (in the meantime they can rake in money from those in-the-know).

IIRC, only 3.1ish GHz is possible with an A64 CG stepping and a Prommy GT right now. Anyway, the 90nm San Diego will be VERY nice I am sure (having heard through an old news release that AMD's 90nm process is not experiencing a lot of leakage [not that Scotty is, excess heat is inherent in the design....a 90nm Northwood would have been nicer] and at the same clockspeed as its 130nm counterpart, has a little more than half the TPD [54W FX55s or something like that]).

Ergh, why can't San Diego, S939, PCI-EX and SATA II just come already....it's almost upgrade time for me!

The 90nm Winchester sounds very very promising, Winchester is the poor man's version, the athlon64 version, and the 90nm San Diego is the FX version, which I doubt if many of us can afford.

The FX chips seems very good at overclocking, with watercooling, i've seen the FX53 do 2880mhz, 240x12, very stable.

I really don't care about SATAII, since the harddrives these days haven't used up the bandwidth of PATA yet.

Interesting.... I'd like to see what a Prommy GT could do with a San Diego (granted that it OCs better than Winchester).

Do you really think command queing's gonna help? I do have command queing drives ready, but right now happy with its performance on raid0.

I noticed that. That's a $hitload of Vmem.

A quick run down

LN2 guys are breaching 5.5Ghz now

I am one of the top non-LN2 at 5.1Ghz

<A HREF="http://fugger.netfirms.com/51ghz.jpg" target="_new">http://fugger.netfirms.com/51ghz.jpg</A>

Im at -95c 1.66v with a c stepping prescott 3.2e ES

Not many people over 5Ghz yet.

Doing it with a prometia or vapo unit is unlikely. The chip con unit at cebit was not a stock unit but it did break 5Ghz.
