With an 6800GT you can't. If I boot @ 200fsb and I raise fsb in windows, lock-up.Quote:

Bogi,
Awesome OC! What kind of cooling are you using? That is not water cooled would it? It can't be air!
Modded Mach 2 GT he says.
Bogi,
MEM enabled or auto? Turbo, standard or auto? What is ct-479 jumper setting?
I reckon you can get into 21s if you put some bh5s in there :) nice work though :P, my 740'll do 2.55GHz, but heat is the concern here, all my chips seem to run ALOT hotter than on my DFI 855...either way, they perform way better, maxing out at 31.7k in 01 with a stock x800xt
Very nice Bogi :)
Ok I just want to know which dothans are the best for oc
(over 2.8 ghz,730,740,750,760,770) on P4C800-E DELUXE on water cooling
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 :)

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.

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:

I've got a wierd problem when overclocking my 740 on my P4C800E-Dlx:
- I boot with a multi of 10 and the FSB at 250 MHz
- I use clockgen to increase the FSB
- I test with SuperPi for each step and it is good up to 265 MHz
- At 270 MHz I get an error during the SuperPi
- I lower the FSB to previuos settings and still get errors
- I get "Not convergent.." at the very start of the test even when lowering the FSB down to 100 MHz
What causes this? :(
Also I cannot boot from bios with a FSB above 250 MHz. Any sugestions there?
.
Edit: Also I cannot reboot after setting the FSB over 250 MHz with clockgen - I must shut down to be able to boot again.
try higher multi
Marlowe
This has been discussed before but since there are 49 pages of replies, here is a summary
After you get that error in SuperPI you must reboot to reset the processor.
When you reboot, Clockgen set the FSB in such a way that it is remembered by the BOIS... in effect rebooting at 10 x 265 instead of 10 x 250. In the PM, the voltages get set after the multi and FSB are set. That way people can use a much higher FSB in clockgen than boot FSB.
Hope this helps
Higher multi? Like 11? But when trying 270 MHz fsb that would give me like 2970 MHz, wich is a bit on the high side :P: I don't think changing the multi affects the SuperPi bug. I have found out, however, that closing the clockgen and/or cpuz progs might solve the SuperPi issue, so it is runable again. My normal setup is booting at 11x250 and increasing to 260 with clockgen after boot. I wish someone would fix just that in the bios..
Thanks for your post and that info! I didn't see it before after I had posted :)Quote:

But honestly, it doesn't make sense. Because there is just the 'FSB over 250 MHz' setting that doesn't boot, I can still boot at 2900 MHz with the FSB under 250 MHz, wich requires a lot more voltage than say 9x255 that doesn't boot.
give more voltage to rams
PS: Wich bios do you use
The RAM is not the problem, I've tested them at 280 MHz before on my prescott. (And I just rebooted and tried to set them on a divider just to be sure). I use the latest bios.. 23 something.
Marlowe
The cold boot sequence is a follows (from what I have read in these posts)
1) Muti changes get set
2) FSB chages get set
3) VCore get set.
So, on a cold boot of 10 x 250 gives 2500mhz which is do-able on default VCore.
When the system hangs, reboots or you reboot, option 1 and 2 are repeated but with the last saved value. I guess the BOIS writer never guessed these would be changed in windows.
1) Set mutli to 10
2) Set FSB to 275
oops, default VCore not enough for 2750 mhz ... therefore system hangs.
Turn off machine and do a cold reboot fixes it.
I have never heard of any one booting so high. Most can not even do 2900mhz using windows tool (myself included). The only people able to maintain >2900mhz are Phase Changers and 1 or 2 air/water cooled.Quote:
I can still boot at 2900 MHz with the FSB under 250 MHz,
If you can boot and maintain 2900mhz at a lower fsb, then be very happy with that. :) .
I personally boot at 10 x 201 then use a program call SetFSB in the startup to set the FSB to 275 which is what I run for every day use.
Hope this helps
There's a new 1010.001 BIOS for P4P800 SE--here . Has anyone tried it? If so, what's new?
thanks, will test shortlyQuote:

Okey! Could be good to know all that :) I understand the changes made in windows is saved and booted from when rebooting. Therefore by setting the FSB over 250 MHz in either bios or windows the same bios issue will kick in. Hopefully it's fixable :)Quote:

Will try to reflash now to see if it helps.
Edit: Didn't help. However this is a minor issue I will ignore and learn to live with anyways :p:
yet to see any boost from the new bios
Using Firefox, when I click the link, I get a download box, and the appropriate message. I tried it several times, and in one case it didn't work, so you might just try again. In any case, I think it's the Taiwan FTP site.Quote:

The Asus P4P800SE 1010 Bios is here:

It's in the US ftp
At least with the P4C800E Dlx yes. Voltage from 1,28 to 1,60 volts.Quote:

thanks all for the great ideas in this forum
drop the mulipler and up the FSB. In benching 10 x 280, I am at 25.5 sec for 1M PI. You should be closer to that. Try 10 x 270 (if you ram can handle it)
if i try to fash the P4C800E-DLX bios on P4C800 with bootblock trick? can i have the Multiplier change?
Dragon - yes, I flashed my P4c800DLX (non E) with the -E 023 BIOS using the bootblock trick and I have full vcore and multiplier adjustment of my Dothan.
