OK, I have to upgrade my 1.8A and plan on buying a 2.8-3.4 P4 (depending on the price). SO I start reading about Prescott and people seems to be really scared of Prescott, becouse of the heat it can generate (at least the bigger ones, 3.2->) So I think, OK I buiy a nothwood instead and starts browsning the stores in sweden. But it seams that Murphy is visiting me BC its not that easy to fin a Northwood these days. I cant find a single shop that that can sell a Northwood 2.8 to me at once. So I wonder, Is Presott the only way now AND do I really need to be afraid of the heat it generates. I got a Abis MB and a Alpha heatsink. AND which is the best Prescott (If I dont need tio be afraid of them)? I have seen that the 2.8 generates less Watt, is that true? PLEASE! I would really need som professional advise on this one. I I do go with intel again, it seems thers only ONE WAY, and it is Prescott.

Dont be THAT worried. I used to live in sweden, and I know how it is with things in stock there :p (originally from sweden but have now moved to ireland). Datorbutiken.com has them instock i believe. otherwise i would think www.itbutikken.se has them. They're danish but they have really good prices and ship to sweden.

Anyways, with a good heatsink and fan you shouldnt need to worry, also it produces less wattage because of the lower clock. Once you start to overclock and bumping the voltage up it will produce as much heat as any other (insert amount of GHz in here) CPU.

Yes they run hotter, BUT they also use more vltage drain on the board, just read some threads here about that.
So if you do get a prescott, make sure you have a good power supply and a great heatsink.

Don't believe the hype.

They don't run that hot, and they aren't voltage hogs.

I'm running a 2.4 @ 3.24GHz on default VCore (1.4v), with my 350W Fortron PSU. Heatsink is a Zalman AlCu 3000 quiet cooler; it's idling at 40C and peaks around 55C (65F ambient).

Yanagi, I have checked ALL stores, and you have to trust me, NO ONE have them in stock now. OK, there are some that have he 2.8NW in stoch BUT they are much more expensive so then is the question, is it wort $35 extra to get a 2.8NW. i can get a 3.4NW at itbutikken for £164GBP which is a mighty good price according to me.
OK, I heard about voltage fluctuation, that its not as stable as NW but that seem really strange to me. I migt not be a CPU related problem.

Sooooo, what to do. To prescott or not to prescott? That is the question ;-)

i wouldnt keep a Prescott if it was given to me.

it hot, its slow, and at that point you aint gonna give a chit how far it can OC.
it will effect your motherboard, it will effect your vid card OC, and it will effect your room temp.

If your running a 2.4A, they aren't exactely the same as the E's.... so don't compare them.

So, what you guys are saying is that its worth some extra bucks to get a NW? Then, what NW is the one to get. I dont want to spend any extra on ne HQ RAMso I plan on running my matched Twinmos PC3200 in the system. SHould I aim for a 2.8 and go for high bus speed (and running the ram at 4/5) or a 3.4NW to get a high multiplier and rum RAM 1:1?

People also had an irrational fear of the Athlon when it first came out also because it supposedly ran too hot. This is no different. Yes it puts out a lot of heat, no it's not a problem 99% of the time.

How do they not compare? Both 90nm CPUs, 1MB L2, Prescott core, did I miss something?

HyperThreading, the 2.4 is produces less heat...

jpeyton, 2.4A is a 0.13, Prescott is 0.9.

I might pay that extra for a Prescott...... maybe. Hmmmm! thought I get any help here, not more confused.

I thought there was more than one 2.4A...the oldie 2.4/400 NW, and the the 2.4/533 prescott...also there's the 2.4B/533 NW, no?

"the oldie 2.4/400 NW" didn't have a letter designation, since there was no previous 2.4ghz P4.

2.4 = Northwood 400Mhz FSB
2.4b = Northwood 533Mhz FSB
2.4c = Northwood 800Mhz FSB
2.4a = Prescott 533Mhz FSB

ah, ok, thanks. I couldda sworn I saw some retailers listing it as a 2.4A when the 2.4B came out. (makes sense, right?)

Why not get an Athlon 64? Same, or better, performance, far less heat/power consumption and 64 bit capabilities to boot...

Anyway, here's an interesting article on the heat dissipation of A64's, Prescott and Northwood.

I'd avoid a prescott if at all possible. It's extremely obvious that it's designed for high clock speeds because mhz sells, and actual performance has taken a back seat, because few people ever bother to look at that.

If you really want Intel, go with a Northwood. At least that's a decent chip design.

All other issues aside, motherboard compatibility is more certain with the Northwoods. That's what I would pick if I were buying a P4.

If you need a new power supply, I recommend a sparkle, coolmax, or super flower, all with 12cm or 14cm side fan. My 2.8c was running hot in an old desktop case with poor air circulation, and the 12cm side fan reduced my temps by at least 5 degrees celcius. Get the single fan models only; the dual fan models are considerably noisier. The sparkle (fortron) is the best ps I've ever used. My new one is only 300 watts, but has 18 amps on the 12v rail, more than enough. I overclock my 2.8c to 3640, and it idles now at about 48-50 celcius, which isn't bad for this case with no fans except the power suppy.

OK, Ill go for the NW. You all convinced me, a little more expensive but more reliable in many aspects. A64 would be grate BUT then I have to get me another MB ALSO. I mainly work with picture and videoediting AND find Intel greate.
