If you can find a couple of bolts with the correct thread beween 25 and 30mm long then the job should be very easy.

When mounting the heatsink, make sure the gap between each of the two aluminium brackets and the heat sink is equal, or the processor core wont be covered entirely by the copper in the heatsink. This isnt as easy as it sounds, since the power supply cables and speed setting jumpers tend to push the heatsink to one side, leading to a ofsett mounting of the heatsink and the core being coverd partly by aluminium.

The center center clip/bracket has to be fipped upside down, I removed the fan assembly to make this easier. The problem then, is that the center clip/bracket isn't designed to be used upside down. In correct orrientation the load is placed through the rounded \/ bottom edge of the _!\/!_ clip, so the relative tightness of the two fastening bolts is not too important. However once the clip is upside down the load of the bolts is taken in two places (each side of the heat sink instead of one place in the center of the heatsink.)

I counted carefully the number of turns on each bolt while tightening, to make sure they were both turned the same number of times. Once the heatsink began to grip the processor core, I made small twisting movements on the heatsink to see which side of the heatsink was gripping the core most. Then I made small adjustments on the bolts until the heatsink seemed to rotate about it's centre when twisting. Then I finished tightening with the same number of turns on each bolt.

Hope this helps.

guys you got to remember to put the white foam that is from the original fan because it helps to not crack the cpu

i have test my PM780es on P4P800se and CT modded

with bios 1008 1010 and 1011 , it s impossible for me to bench over 220 mhz ram 5-2-2-2 :/

i have vcore vdimm vdroop and vchip mod but no way :/

anyone has an idea ?

Hi guys

I just bought a Dothan 750 and Asus P4gpl-x mobo second hand. When it boots, it says cpu overheating. If you go into the bios itself it reads random temps like 124c then -124c then it shuts down.

The heatsink isn't warm yet it is touching (I cleaned off the paste on the heatsin k to make sure).

The previous user had it running ok.

I'm guessing after clearing the bios I need to re-do some settings to get it to work correctly first?

Cheers for any help :)

124c! OH! You should check your mounting system. Stock HS? The hs should be at least warm if CPU is 124c.

I put in a 2.4c which works ok, so I think it's the heatsink itself (?). I've ordered a Zalman flower heatsink which should do the trick ;)

Hi everyone,
I currently have a p-m 750@2.8GHz on 7700AlCu. I am kinda worried since temperatures are going too high (close to 60C). Do you think that switching to the SonicTower will be an improvement ? Any testimonials of users with previous experience, please?

which RAMs u use?

only 2x256 BH5 which can bench on p4gd1 at 276 and ever bench on nf3 amd at 282 @ 3.8 vdimm

a friend send me an eeprom of p4c

gonna try with it

what multiplier are you using?

i had similiar issues before my chip went south. but i think it is a common
issue with the 780es' chip (not the going south ;) bit).

i had the 780es running on a p4p800-se, still have the board though, and
it was / is running the 1009.003 bios iirc. to me that was the best bios for
the p4p800-se.

anyway. i could get the fsb up to 290, with asynchronous ram at 10x only.
one time i also had another 780es that would do a little less fsb-wise
using the same voltage / multiplier settings, but ended up somewhere
close by in terms of absolute speed. but both chips behaved very much
the same in this multiplier vs. fsb issue.
with the multiplier at 12x i could get a max of 243 mhz, and the higher i
would go with the multi, the lower the possible fsb would get. - and i had
not even maxed that chip yet.. was running ~1.5v, so plenty to go...
all those tests were done with the ram-divider set to 5:4, so at fsb 291
the mem was running 233-5-2-2-2, 2x512mb khx3200 (bh5) btw.
with my 760 running on the same board, i had my fsb up to 305, ram at
244-5-2-2-2 and went through am3 with it (the maximum was 313, 5:4,
250-5-2-2-2) - so the board wasn't and isn't the culprit.

also going to lower multipliers, like 9x, didn't help one bit. actually with
the 780es' it seemed to get worse fsb-wise. 10x was where i could
squeeze the most out of them. the 760 on the other hand loved the 9x,
as i could top out the fsb there... strange little fellas. maybe a regular
780 (retail) would do the trick as some suggested?

i test under casacde so i boot bios a 200 x 17

on windows all the coefs make me errors :/

do you have a link for the 1009 beta bios ?


the problem is that i want to bench 1:1 around 3700 :D

i'm sure i have all the 1009 bios files around (001, 002, 003, .. ). i'll check
once i get back from work and am awake again, but i'm positive i have
them. i'll pm you when i find it tomorrow afternoon - can't check from
here as my server is not accessible from the outside world :D..

3700 1:1 whoa 284x13 or 264x14... makes me wish i had a cascade at my
disposal.. :)

for the p4p800 se

ok sky and thx ibby :)

Is this also generally considered a good bios for the p4c800, or is it better to stick with the 1024.001?

a P4 2.4c must boot with all the bios on P4P800se ?
have found the pb :p

plain p4c or p4c800e-dlx?
anyway, i think there was another bios named 10001_023 (p4c e-dlx),
but i wouldn't know if that was any better than the 1021 or the one
i mentioned above. i never got hold of a p4c800.
also wasn't there a "special" p4c bios customized by tony? i think i do
remember something at the very back of my head. hm


and skirms... is that a default fsb100 part or 133. i don't know much
about the p4's, completely bypassed them, but maybe it's the same
issue as with the p4gd1 that would not like to be flashed / run with
a stock 100 cpu? (just guessing)

What is the best bios for p4p800se?

Anyone help, please :(

u'l probably ahve bad contact with the core,are arent using thermal paste


or maybe your voltage is to high?

Its the bell and whistles edition :) (p4c800e-dlx) Hmm Think theres a 1024 out now, will give tony a bell and see if he remember such a bios, would be good to have. Thanks for the info!

Voltage is close to 1.6V. How better is the Sonic Tower from the CNPS, will there be any significant improvement if I replace it ?

Just in the middle of fitting the huge Zalman flower copper heatsink to my Dothan 750.

It's a bit of a nightmare to fit.. similar fitting as the 7000 range but it sits a little too high atm so isn't getting very good contact - idles ~45c / load 70c+ lol. I'm having to force small pieces of foam between the bracket where it pushes onto the p4 heatsink adapter, so it pushes the new heatsink down a bit.

I'll post some pics when done. Currently running at ~2.3ghz

70C in full load at 2.3GHz ? I am at 63-65 at 2.8GHz. You really have a problem there.

is there anyway to mount a swiftech apogee water block on he ct-479? i mean even with zip ties or something... im highly considering changing out my system for the p4p800-se but only if i can mount my water system on it.
