Comment:

I currently have a Pentium 4 HT with 3.0GHz (L2= 512KB, 800MHz FSB) Northwood.
I bought a Pentium 4 HT with 3.4GHz (L2 = 1MB, 800MHz FSB) Prescott.
I am going to replace the old 3.0GHz with the 3.4GHz, now I am aware that Prescott’s run faster because of the 1MB cache, but I have read that they get hotter. I have an all copper heat sink right now with an 80mm fan, is that adequate enough for 3.4GHz? Does anyone have or had a 3.4GHz Prescott before? How hot did it get?
Thank You,
Jesse

"I am aware that Prescott’s run faster because of the 1MB cache"
Actually, they don't.
"I have an all copper heat sink right now with an 80mm fan, is that adequate enough for 3.4GHz?"
Depends on how large the sink is. Just monitor your load temperature. If it climbs above 70C, you'll want to grab a better HSF.

I hope you got your new processor cheap, because if you didn't, then you just wasted your money. Because you aren't going to see any real performance over your older processor.

I agree with Cobra. You'll see little or no difference in performance.

I would have to agree,I would of left the processor and just max out the memory.
I don't think you will even notice a difference..

I have a 3.2Ghz Prescott and kinda wished the Northwood was still available when I bought it.
I was using an Zalman CNPS7000-CuAl but the temp went to 65-70 degrees celcius on load.
So, went watercooling with the Zalman Reserator 1 and now it's about 55 degrees celcius on load.

His RAM is at 4GB. That's kinda maxxed out to me.

Would the 1MB cache make much of a difference over the 512kb cache?
I know with new computers there are ones that have a 12MB L2 cache, like the Quad core.(Intel Core 2 Quad Processor)@ 2.83GHz.
I guess I am asking does the bigger cache make a difference?
One thing that confuses me is what would a 2.83GHz Quad core be equivlent to if it was a single core? Would I do 2.83x4?

If the P4 with it's NetBurst architecture was any good, Intel would have stuck with it. But they abandoned it completely & developed the Core architecture used in the Core 2 Duo & Core 2 Quad.
"One thing that confuses me is what would a 2.83GHz Quad core be equivlent to if it was a single core?"
It would still be a 2.83GHz CPU.
