p4 2.533ghz now at $249 on pricewatch!!!

Nice system your building there Richdom
Pack date is refers to when the chip was packaged. It will be on a white sticker along with your product code, batch#, and fab (location of final assembly)

You should have no problems running that at 3Ghz. In fact with that memory you should be able to run the 3:4 divider and hit 426. Which will be an extremely fast machine.

If you've never built a system like this then I suggest taking it slowly. Put everything together, boot up and install your os at stock speed and make sure everything is working properly before you go o/cing.

I also recommend getting some artic silver3 if you already haven't and carefully take of the thermal pad that comes with the heatsink.

American Express..............don't buy tech gear without it.

60 day Best Value guarantee means if I find it cheaper ANYWHERE in the next 60 days they will give me the difference!

I buy with confidence from wherever b/c I know I have 60 days to find it for less and report back to AMEX.

Works great on tech stuff!

Everyone's shooting for 3Ghz but is this 2.53 chip gonna be able to run a fsb of 158?

I hope it's not gonna be like those 1.6As and 1.8A where you had to get one with a late pack date.

Thanks for the tips Dug!

I had considered the Artic Silver thing but heard that the p4s ran cool enough to handle it. I'd rather be safe than sorry so I will see if I can just add that to my order.

I'll report back with the pack date.

Well I have this all assembled and running.

My pack date on this P4 2.53ghz is 5/14/02.

It's all running stock speeds now until I work up the cojones to turn up the heat.

Sandra tells me the CPU temp is 25C/77F.

I AC3ed the CPU/heatsink. There is a fair amount of "guesswork" involved. I don't like guesswork. How think is .003mm anyway?!

I am truly uninformed when it comes to the benchmarking that all you folks seem to use. I'd like to run some tests and post results but don't exactly know where to start/go.

I ran something called the "CPU Multi-media Benchmark" in Sandra and got these results:

Integer iSSE2 10105 it/s
Floating-point isse2 12350 it/s

How am I doing? Is that ok?

Thanks

and the sis648 isnt looking like to great of an overclocker....

Hmmm.....where did you read/hear this?

I'm thinking of "jumping ship" over to Intel, particularly the 2.53 since the price has become reasonable. I'm interested in the SIS648 boards for a couple of reasons. One, the reviews I've read so far say the performance with ddr400 ram is on par with Rambus, albeit 800 but it also supports 8X agp that would go nicely with my future NV30.

I plan on o/c'ing for some benching but return to stock speeds for every day stuff.

Am I making a mistake here?

True DDR400 should be closer to PC1066, even PC2700 is on par with RAMBUS PC800.

i wouldn't concern myself too much with performance of chipsets right now, as intel is planning on releasing a dual channel ddr chip within the next 6 months or so (i think), so get a good chip, decent board, good ddr ram. once you go dual channel with ddr then your bandwidth should well exceed what the p4 can handle. really to equal 1066 rambus you'd just need dual channel pc2100 ddr. so with pc2700, you wind up with more bandwidth than the p4 can use (with it's 133 bus). of course you're gonna wind up ocing it, but in short, this is the point i wanna make:

you will not have to run your memory at extreme bus speeds to get extreme performance.

basically pc2100 ddr modules (yea the real cheapo ones even) will provide performance on par with (or higher than due to lower latency) current 1066 rambus. once intel (sis and via are already developing chips too) releases dual channel ddr chips, you're gonna see some mad performance and oc's with p4's.

imagine your current corsair xms3200 module supports a 200 mhz bus speed (thus 400mhz since ddr). say you could miraculously take your p4 chip up to 200 mhz fsb. in this situation you wind up with 800 mhz processor fsb (200xquad pumped), and also 800 mhz memory (200 x 2 channel x ddr). lets see, that provides you with 6.4 gb/s memory bandwidth and a processor that could use it. the future looks damn good
