yep, decided to carry this 478 2Ghz baby to the moon! Asus P4T-E, standard intel H/S. Anyone can give me some advice on what Heatsink to use? Dreming of hitting a 133MHz bus and 2.66Ghz, what are the chances ya figure?

I would say very good especially if you remove the IHS! After removal you will need to possibly make a shim. I made mine from over lapping clear packaging tape squares with the center cutout.

My S478 PIV 1.5 went to 133Mhz without seeming making any changes in stability and temp. CPU Full Load is 50C

The heatsink fan setup is just the basic bog-standard stock.

Whats the rest of your system like and how well does it perform, I'm actually quite disappointed with the P4, even with the overclock, maybe I'm doing something wrong somewhere...

i just got a radeon 8500 on it, i use the XP Dualie machine mostly these days, with a an Asus Geforce 3, the PIV is a test machine, might sell the processor and get a Northwood, dunno, waiting to see if its worth the bother..as for your machine, i'd say even with the Piv's short comings, it should be blazing fast, post your system specs and os setup and maybe we can give some advice

Tom's Hardware did a P4 overclocking test. they said voltage and cooling was VERY important. They say most 2.2Ghz will do 3Ghz, but require water cooling and 1.85v. Without water cooling the throttle protection would shut the system down as the temps went up.

He also said a distributor sent him a hand picked P4 that they had sorted to find (likely testing hundreds). This thing managed to hit 3Ghz with air cooling, but they said this was VERY rare. 3Ghz with water cooling and 1.85v was easy for most 2.2Ghz. He did have the radiator on his water cooling system outside his window so the system was running at 0'C.

He also stated that a DDR board was almost a must because the RDRAM could not take 133Mhz or more without dropping the speed to PC600 (indstead of the stock PC800) using a 3/4 multiplier. This was pretty hard on the performance, but the DDR memory could handle the higher speeds easily.

Now watch out which 2Ghz you get. Make sure it is the .13micron version with 512K L2 cache. If it is not you will likely not make it to 2.2Ghz. These are usually labelled as 2.0A or 2.2A for the new Northwood cores.

So a quick recap. DDR motherboard, good cooling, lots of voltage, a Northwood 2.0AGhz P4, and a bit of luck will give you 2.66Ghz without too much trouble (3Ghz if you go nuts).
