FYI for the front page Stryg .. the P4P800-E supports Ct-479 with BIOS 1007 and the Beta BIOS 1008.001 has vcore change up to 1.6v ... too bad no multi change in BIOS yet .... :(

FYI for the front page Stryg .. the P4P800-E supports Ct-479 with BIOS 1007 and the Beta BIOS 1008.001 has vcore change up to 1.6v ... too bad no multi change in BIOS yet .... :(
I installed a 730 into my P4C800 Deluxe (non -E) today, and overclocked it to 250/11, 2.75GHz. Thought I'd post for someone to take a ook at and advise (am I doing it right?), and also incase it helps someone else.
BIOS: 10001.023 (the recommended bios for my board in the "how to & fixes thread), flashed using the older version of AFUDOS (to get around the BIOS mismatch error when flashing a "non-E" board with an "-E" BIOS, and with the following parameters: AFDOS /i<ROMNAME.ROM> /n /pbnc to avoid ending up (possibly) with a dead board.
CT479 Jumpers set to 533
BIOS:
Vcore: 1.5v (actual, Asusprobe)
Multiplier: 12 (lowered later in Windows to 11 with EIST)
FSB: 201 (raised later in Windows to 250 with Clockgen)
Turbo mode
PAT: Auto (875 Teak utility confirms it to be enabled)
2.5, 3, 3, 7
Very pleased so far - 27secs SuperPI, and 29000 in 3DMark2001! Haven't banched much else, but it feels a lot faster in games. :D
i cant really seem to get a 'good' contact on the cpu and hsf (zalman 7000) or not one i am happy with........
i am thinking of going with a xp-90, and just bending the brackets, has anyone tried it ?
Stigggeh,
Try to flip the brackets upside down.You might want to bend or add washers to shim the heatsink in place. Also ,see the first post in this thread on how to mount the Zalmans to the Dothan.
You wont find any air solution that easier to install than the 7x00Cu from Zalman.Quote:

yeah i have tried that, i also tried a metal spacer wedged in the middle, i may just be i need to get familiar with the temp sensors 38 idle and 50c load, my old p4 was always very low, so this seems more likely to be correct. i was expecting lower, i am just a little worried as the hs does not seem to get very warm. when the fan is off.
i will keep trying and report back if i manage any better results.
Can anyone help me with this?
My P4 system (in sig, but running at 3.8GHz) scored over 6000 in Sandra's memory bandwidth benchmark (FSB 255) whereas having upgraded to a Dothan at 250x11, 2.75GHz now my system only scores around 5000. The FSBs are almost the same and I'm using the same memory etc. Any ideas?
That sounds about right. It's going to be a little lower than a P4.
can somebody advise me wich dothan shoud i buy to get max oc over 2.7 ghz (740,750,760)
Hmm, the temp outside is dropping ( so inside to ) and my overclock is getting slightly better! Can't wait for winter :D
i've the same problem like you Stigggeh, i get idle 34-36°C and 51-53°C load on 1.51 Vcore and 2720mhz with the 7700cu.Quote:

the room temp is circa the same (around 27°C).
i turned the screws so hard on but i don't know what it can be because of the high temp.
but at least my result today :)

Remember:
Temps probes are not to be trusted! :)
I get almost 10 degress lower readings on P4GD1 than my former P4P800SE and P4C800-E Deluxe.

i am gonna try to fit an XP-120, heard they can kill dothans, i will be careful, i am going to try to use a method of bending the clips, the nylon washers and moving the clips on the XP120......... somehow i will get it to fit.
:toast:
My PM 740 boots into windows @ 2.9 GHZ now, and is 2.820 stable in games, prime and super pi with stock heatsink.Quote:

All currently air cooled on stock MB, stock heatsink with cheap ram.
Great bang for the buck!

you got soo high oc with no mods?
I have a Pentium M740 with a Asus P4C800 Deluxe but i can't change the multiplier with this mobo(only 13X),i use the latest betabios 1021D.004.
Anyone a idea how to change the multiplier with this mobo?
Max overclock with the stockcooler(ct-479) is at the moment 2750Mhz@1,45V,higher vcore doesn't give me a higher overclock so i don't know if it's my memory (i did the vdimmmod so vdimm is 3,15 but max freq is still 211Mhz,same as with 2,85V) or the temperature(with Pifast higher than 50 degrees)
I did try the P4C800-E bios but this didn't work ,it only boots once and than i have to reset the bios again.

unless you have a p4c800-e deluxe then you cannot change the multi permanently in the bios. You can flash the ED bios to the Deluxe & 'vanilla' p4c800's which willlet you change it once but as you found you lose all the changes after boot.
We need a bios from Asus for the deluxe & vanilla boards to match the one they did for the p4c800-e deluxe !
I can't highlight the multi,the ratio status is locked :(Quote:

setting up my newly arrived dothan rig tomorrow SOOO... use the thermal pad stuff on the ct-479 heatsink or scrape it off and use artic silver?
My temps dropped by 6-7 degrees when I replaced the original thermal pad with AS5. Go for it.
