The P-Ms with 533 FSB clock better than the P-Ms with 400 FSB.
P4C800+adapter+Dothan at 2400MHz (12x200) seems to be equal to FX55 @ 2.6GHz (13x200) as far as 3DMark2001 SE goes ;)
32k w/ X800XTPE at default clocks.
This is really frustrating I'm helping pcboarder set up his 1.6ghz 533fsb Dothan, p4c800-e deluxe, ct479 adapter, ddr booster, and 2x 512mb mushkin bh5, and the damn thing just won't work. We've spent close to 20 hours on it, but it simply will not come out of locked mode. It stays stuck at 800mhz, 1.136v. Tried all manners of software unlocking, the multi is just l;ocked, same problem that kingping had. His solution does not work. I need this to work, it's pcboarders only pc.
To compound matters, it is not stable at 800mhz either. The mobo gives a voltage out of spec error and heres the weird part:
it is 100% superpi 1m stable, but cannot even start up any games, reboots if left idle for more than 2 minutes, hardlocks/reboots/BSOD's after about 5min on the internet with it.
Asus blames Intel, Intel blames Asus. Both companies reps suck.
What is going on? I need this to be fixed, and fast because of school.
Try reflashing with /n /pbnc switches?
Had the same problem yesterday when I started w/ the 1.6G Dothan and reflash fixed it.
a quick Mark03 run I made this morning @ 2.7G and easy 630/630 card clock:

Take a look at that GT1 :D
Its a monster! :hehe:
hey macci where did you get that adapter and what bios are you using? are there any multipliers and voltage options available in BIOS?
Got the adapter from our shop. Useing the latest BIOS 1021 (from ftp.asuscom.de). At the moment the BIOS doesn't give any Vcore or multiplier adjustement. Everything is adjustable from windows thou :)
I have reflashed the bios several times with the dothan in and a couple with the regular northwood but it just wont work. as comppro said it is stuck at 800 and i have no clue where its messed up. Asus says its the board and intel says its not the chip. I am going to hope to get a board from the rma dep and be able to get it in b4 i send the old one out b/c of having to write papers. I hope this will fix the probs.
EDIT: I tried volt mods and it still is stuck at the 1.185 volts.
Slightly oT, Macci does that mean that all boards listed on your site work well witht he ct-479?? ANy advantage going p4c800e-d compared to p4p800e-d on the dothan platform?? Any benefit to 875 vs. 865, or is it a wash like it was 2 yrs ago with p4?Quote:

Do yo have any links to the p4p800 bios 1021.003 asus are only showing 1021.002 in the beta section and on the ftp server.
This woould help me loads i could use my ddr booster on the p4p800 instead of the p4p800-vm i have been using.
Just in the process of modding a xp-90 hsf to fit with the ct-479 adapter.
Found it on ftp.asus.de server :banana:

:toast: Looks good macci! Is that copper heatsink a custom job?
I was thinking I could take a copper s478 heatsink made for 70mm fans and reduce the height of the fins. The ct-479 clips would work with it.
Soon, I hope to do some more Dothan overcloking myself. After less than stellar results with the Celeron-M 350, I picked up a P-M 730-533fsb and another asus adapter...

I have the p4p800 running with beta bios 1021.003 and a 1.6 400fsb dothan.
the bios shows the cpu as locked multi of 16 and no vcore options.
you can change fsb and when at 133 fsb can choose between ddr266 and ddr333 ddr can go upto 2.8v.
i am getting the same max fsb with the p4p800 as with the p4p800-vm anything over 170fsb and the system locks. memory was at 1:1 so no problems with that and i dropped the multi down to 10 so the cpu was only running at 1.7 ish must be the ct-479 stopping me going over 170 fsb or this dothan just cant handle the high fsb but is ok running at over 2.5ghz no problem with multi of 16. I will try upping the vcore with a u-wire mod see whats that gives me
I have a xp-90 modded to fit the p4 bracket with a ct-479 works very nice.
edit: i changed the jumpers on the ct-479 to 400fsb as the p4p800 didnt detect the 533fsb anyway and i can now go over the 170fsb.
I did the u_wire and the system crashed at 2.6 on teh cpu just like the p4p800-vm i think thats the limit of this 1.6 at 1.55v
it didnt go much over 170 only to 173. i have reached my limit with this vcore
163 fsb multi x16 vcore 1.568 ram at 218 2-2-2-5 turbo enabled 3.3v cpu 2616.
super pi time 28sec.
if i drop the multi down to 15 then the 173 fsb stops me getting higher.
Got the 730 1.6GHz chip up to 3GHz now w/ watercooling and 156W Peltier :)
http://www.akiba-pc.com/d16g/d16g_3006_id.gif
CPU-Z verified
also runs SuperPi 1M at that speed. 24sec (0.126 from 23sec zone =))
I'm sorry for not using the search function....
or for reading this whole thread, lol...
But could someone sum up the ct-479 process?
I mean what is this about "must boot at 200" and 750 and 760 and 770 cpu's can't boot at 200 on air, etc, etc...
Can someone give me the readers digest version on how to setup the dothan on the ct-479? THX!!!
C
Great results macci :toast:
Still stuck at 3189 for benches on DI :(..... and not a bit more.
for me, it wentQuote:

Well, remove the smashing adapter part (I wish that happened but its not mine so I can't) and you have mine and pcboarders experience.

I don't know about the "must boot at 200". Maybe to get pat on 865 boards?
I can say that I didn't have any problems with a Celeron-M / ct-479 / p4p800-se setup (although that cpu had only a 13x mult.). Trying 730 cpu this weekend.

How far can you push that C-M 350?Quote:

Hit a wall at 2.25 Ghz. That was at stock voltage with stock heatsink. Tried more voltage and a more powerful fan but no increase. I actually killed something (adapter or cpu) when I got above 1.6 Vcore. I'll find out what died this weekend. The cpu was an older (week 0414) C-M 350. There are newer J- model 350 and 360s out now. They dont seem to be any more expensive than the older models either.Quote:

p4p800 gives good fsb /memory options but multi is locked and no vid options.
if only i could add the vid and multi options to the p4p800 bios it would be perfect.
I found using cpumsr i can change the multi and vcore in windows so i can increase the vcore using a u-wire mod and then decrease the vcore using cpumsr.
still Cant get the fsb higher than 172 no matter what multi i use but as i cant change the multi in bios on the p4p800 i cant try setting it to 200fsb as macci said.
still at 2600 with memory turbo and 2225 timmings 3.3v the system is very quick.
@ Macci do you have a best pic of the vcore mod ? I think i will do it on my p4p800 VM
I dont understand what you are saying compaired to this:Quote:

Both reviews on P4P800SE.
i have a p4p800 with bios 1021.003 not p4p800-se
