Intel 850E compatible with 800mhz fsb??

Hi guys;
I got the upgrade bug. I feel the need to spend some money and move up a little in the pc world.
Here is what I have.............
asus P4T533-C 850E chipset
512mb of pc1066 ram
intel p4 2.4 533fsb
Two WD 80gb 8mb hdd
40X burner
ATI 9700pro

I am planing on building a new system but not untill I get back to Canada in six months. And even then I may wait a few more months to see whats happening with PCI-X the amd 64's and prescott and its successor.
Is my 850E chipset able to run a 800fsb cpu??? It is only a few dollers more then the 533fsb cpu's so I will get a 3ghz cpu if there will be no problem. My thinking behind this is, that if anything should ever happen with the rambus ram I got now, I could just jump into a 865 or 875 chipset mobo and ram. Rather then replace this outdated ram.

Feel free to share any idea's or suggestions
Thanks

    Part of the key to my answer (NO, it can run a Northwood but not an 800 FSb HT) is in the 533 numbering of board and the 5 as second digit in chipset number. It is a gen 8 processor, subgen 5 chipset, top end 533 MHz FSB--for real use of an 800 FSB CPU you need a subgen 6 or 7 chipset. AFAIK, the 800 FSb hyperthreads cannot run as always single pipe at all well, and a single pipe 800 FSB processor would be having to run at 533 or 400 FSB to let that board post.

    If you want ultimate, shift to an 875 chipset-- it will suport faster RAM better than the 865. BUT, the 865 will use older RAM than the 875 will so you might end up buying RAM if you go to an 875 chipset. If the 875 has the correct power control structure and you have a real robust PSU to support that board, an 875 board might run a Prescott, but that would need more detailed case by case looking up to tell you what would be very likely to do that. If the board is COMPLETELY built to Intel specs, an 875 chipset should run an early Prescott. Most are not built totally to Intel's specs, unfortunately. I would also expect different motherboard models that support Prescott better than any board now out except a few recent server boards to come onto market.

    For now, best Intel bet is an 875 chipset board for performance, an 865 for economy. Prefer an ICH5 or ICH5R south bridge(R suffix stands for RAID) in either case. Avoid an 865 paired with an ICH4, this is a poor combo, and have seen a few of those offered.

    In a word, no. The i850e cannot run anything higher than a 533MHz bus CPU.

    Sorry I wasnt very clear. It was early in the morning.

    The question I was asking was, can my board run a 800fsb cpu at a 533fsb. Would there be any problems running the P4C as a P4B?
    I see this as the cheapest upgrade I can make, a cpu upgrade that is. And like I said in the first post, the reason i want a p4C is that if anythging happened to my rambus ram I could get into a 865 or 875 chipset board. I am not ready to spend the money on a new board and memory right now, when I plan on building after my return to Canada. But at the same time I dont want to be stuck with buying a new board for a p4B is anything should happen to my rambus. I simply will not replace the rambus ram if anything should happen to it.
    Keep in mind I do have to pack all my parts and take them as carry on during the flight home. It all made it here safe but ya never know what will happen.

    They're trying to tell you no, unfortunately. For example, in an E7205 (GraniteBay) chipset board which supports 533fsb (133X4), a 2.8C (200 X 14) boots up at 133 X 14 = 1862 and most of them max out around 180ish fsb X 14 = 2520 for a woefully underclocked processor. 865/875 mobos support 400/533 cpu's but older mobos mostly dont support 800 cpu's. It may or may not even boot up. Hang onto your dough is my advice. Or, if you had a sale for your 2.4, 3.2's are way cheaper now.

    865 or 875 are the only 2 you would want to get.

    ok
    Thanks guys.
    if I can find a buyer for the 2.4 I might upgrade. But the odds of selling my 2.4 here in korea are slim to none.
    Hang onto my money looks like the best bet.
