Difference between 533FSB and 800FSB?

Sorry for posting such a noobie question to you all im no to good with computers yet. I just realised that iv ordered a p4 2.4 533fsb and not the 800fsb version is this going to make a huge difference to the performance of my computer.
Thanx

yes it will make a fair difference

the 2.4C 800fsb chips have hyperthreading the 2.4B 533fsb chips dont plus the extra bus speed helps quite a bit

id get it changed m8 if i were u

thanx mate i may well do that once i get the money lol i appreciate the responce : )

Make sure that your motherboard supports 200mhz FSB.

;) P4's use QDR FSB, so 100x4-400FSB, 133x4=533FSB & 200x4=800FSB. The P4 is VERY hungry for both memory and FSB bandwidth and as such really excels from things like Dual Channel DDR and fast FSB. Having the 800FSB CPUs gains you HT (as said) and that's a wonderful piece of technical wizardry which makes everything you do in Windows seem that little bit quicker, smoother and more responsive. It is over-hyped but well worth having. The 800FSB CPUs tend to o/c better than the 533FSB and the boost of 800FSB means a 2.6ghz(800) can often beat a 2.8ghz(533). ALl you do need is a mobo which can offer 800FSB and preferably some decent headroom for o/c'ing too. i865/875 are top picks.

the difference between 800Mhz & 533Mhz FSB
800 - 533 = 267Mhz is the diffference! or 50% faster FSB

Most importantly you need either an 865, 875, 848 or one of a few select 845 mobos rated at 800Mhz FSB operation.

Obviously the 865 & 875 are the way to go since they have dual channel memory and provide a nice boost in games & other memory intensive operations.

800Mhz CPU's have lower latencies due to higher FSB, have Hyper-Threading helps in multi-tasking, and are great in the 865/875 motherboards for great memory bandwidth.

Send it back and get it swapped for the 2.4C 800

©DinG© - i'd suggest posting what motherboard you've got some we can check to see which processor you should be using, it may be that swapping it for the p4c processor is not possible.

I wouldn't do anything till you confirm it will work in your system.

Thanks

hes bought a Asus P4C800 Deluxe

so yes the 533 would work in it but as already said he should return the 533fsb chip without opening it and get it changed ,if hes lucky the place he ordered from wont charge him anything otherwise he'll have to pay a £10ish restocking fee

doubt it's gonna be 50% faster than a 533FSB one but still quite a bit quicker and as mentioned before the 800FSB ones have HT which is always a nice bonus

Yeah - its well worth getting the 800FSB ...

Performance - a little more omph, HT - SETI or UD very useful, Overclocking ... just got a nice 2.66Ghz P4C - 3.32Ghz on stock cooling with the IC7 MAX3, with a little burning in it'll go further! Only volts up was the RAM to keep it at 5:4 rather than moving to 3:2!

The 800fsb version isn't a great deal faster than the 533s, i've found. The main difference being memory bandwidth (only really noticed in benchmarks to a point), as far as gaming is concerned theres very little difference. HT is a nice bonus though I must admit :)

;) If you want top perf and better future-proofing (as much as you can with Intel) the 800FSB mobos make the better deal, esp as you get HT and don't pay any extra for the 800FSB CPU. However the 533FSB ones are still very fast and they along with the mobos should be found for very good deals ... lovelly if you don't mind lacking the top perf offered by 800FSB. Of course AthlonXP makes even more sense in the price-perf while Athlon64 makes the most sense if you're hungry for the best perf ... but you're better waiting for Skt939 for that.

Thanx for the help people! : )

Also, there is a certain kind of a 2.4c (c=800FSB) Its model number is SL6Z3 and its baisically a p4EE that didnt make the cut. Its been underclocked to 2.4ghz and sold as such. These are retail CPUs not OEM. They commonly get up to 3.5-3.6Ghz on the RETAIL cooler!!!! If you are luck enough to get one of these then it will certainly be worth getting the 800fsb.
