in case there are some processor nazis who dont visit 'General hardware' 😉

Well if you have a board that is only 533fsb capable the best you can get is an 3.06ghz chip but it will have HT and this will help you nicely in some apps....The other thing would be is get a higher speed P4...Prescotts do better at some apps in encoding if they can take advantage of SSE3 codes...otherwise a northwood is cooler and possibly a tad faster clock to clock versus the prescot....

If you are ready for a system wide upgrade get a dual core setup either from X2 (higher priced but the fastest) or INtel (lower priced chips but slower in comparison.)...both of those choices will blow the doors off of anything that a current best speed single core can do....

Thanks Duvie ! I replied in the general hardware thread, and I was wrong on the cpu. How high an OC will a 3.06 do easily ?

I have seen them in the 3.3-3.4ghz range.....

my board is capable of 800fsb along with HT. I just didnt buy that high end cpu when i built it about 3 yrs ago cus i didnt need it. my current p4 is northwood (im pretty sure). so if im going to 3.0Ghz 880fsb w/ HT..i shoud get a northwood or prescott?

Whats SSE3? what does that give me...otherwise i would prefer the cooler, and tad faster northwood. i have a zalman 7000 cooler, so i hope it can handle the HT and higher temps of 3.0ghz.

the system wide upgrade is out of question for now.

I would get a 2.8c (reasonably priced now) and try for 3.4ghz (many can get there)......

The processors run pretty linear in this type of app so a 10% increase in speed will get yopu close to a 10% increase in performance.....

A 3.4 could give you a 17-18% gain in speed and possibly performance.....

Prescotts at lower speeds dont cut it compared to northwoods so you really need 3.2 or greater to get the benefit out of them....

SSE3 is new code written in the prescott not available in northwood.....Reviewers said this was placed in there to try to recoup some of the loss the prescott gave the P4 with its longer pipeline and thus latency penalty....


Zalmann 7000 should handle a 3ghz no problem...My stock HSF could....


Are you trying to oC your current cpu more???

my current cpu (2.4ghz) is OCed to about 2.9. I dont think i can overclock it more without getting a better ram (right now just 2 separate 512 sticks @ 333). mobo is cable of dual channel up to ram with 400 (PC3200).
Im really looking to get a new cpu, but they are running around 190, eh!! :\ (for the 3.0 ghz). the 2.8 is around 160. I might as well go to 3.0 and try to reach 4.0...i can, right?

Not likely....3.0ghz to 4.0ghz is no gaurantee even with water and no northwood will get that high...you will need 600 series P4s...You would also need an inexpensive one and with a low cpu speed unles syou can unlock multiplier it is going to be a high FSB and thus your ram will severely limit you....

how are you running a 800fsb chip now with 333fsb ram, and Oc'd to boot???

im running a 533fsb(marked) cpu on a 800fsb max capable mobo with 333 ram. The ram isnt OCed. Just the cpu is OCed to 200something fsb...i forgot what the exact reading was that gave me 2.9ghz speed on a stock 2.4ghz p4. anything im missing here?

i guess i will try to find a good deal on a 800fsb HT cpu and some 400 dual channel ram. I think if i can get those around $200-225..ill prolly buy it. right now..seems like its gonna cost 260-300. so the hunt begins.

HT will give you a nice boost on top of % increase in speed on top of 5-10% for dual channel ram and 400ddr.....Should be a nice boost for you....

I can tell you going from 2.4b@3.24ghz to 2.4c@3.5ghz was.....The 3.24ghz non HT in encoding was like my P4 at 2.8c....A 2.9 non HT chip would be less then a 2.8 northwood at stock easily!!

If you run TMPGenc you will and can see a 19-22% increase in performance from HT on alone...
