I can't get my Dothan to boot with the P4GD1 :(
It does boot with a Celeron in it.
I've flashed to 1005.006 bios and the official P4GD1 105 bios and neither work.
I've tried two adapters, might be cpu? Well I don't know.

Also of note is that my PCI/AGP lock just fine no matter where I boot up. I just booted at 166 and clockgened up to 200 no problem. Also, I'm Priming 2400mhz @ 1.25vcore, so I seriously doubt that 2500mhz is a natural limit of this chip.
2500 @ 1.25vcore priming now. *Sigh* this chip would be a monster if I could get around this lockup @ 2.5
Edit: Flashed back to bios 1008 and my limit went from exactly 2500 to exactly 2400. This is getting quite irritating.
Seems to me that all these chips are very similar , does not matter if you have a 730 or a 770 it will hit the wall between 2500~2800 on air .Quote:

A lot of 2500Mhz PM are faster than some 2800 .....
Well, I'm not interested in the difference between a San Diego and a Dothan. I want a dothan that does 2700mhz+ for my own reasons (not beating san diegos at Spi).
I highly doubt it's a chip limit since It runs prime stable at 1.25vcore (significantly undervolted), and since it changes with different bios. Here's my experience so far...
1. Three different bios on p4p800se and two different bios on p4c800-e dlx. All hit a wall at 2520 or less.
2. Two different 730's. Both hit a wall @ 2520 with p4p800se and bios 1.009.004beta
3. Cooling makes no difference, voltage makes no difference, ram makes no difference, None of the bios settings I can find make a difference.
So my natural assumption would be that the ct479 has something to do with it... but I sold the first 730, and the buyer hit the same wall so if it is the ct479, it's a common issue with them.

How do i do that on a p4p800se? I'd assume set system speed to "standard" (instead of turbo/auto) and MEM to "auto" (Instead of enable).
Incidentally, for whatever reason, my p4p800se boots just fine with "performance mode" (as titled in cpu-z) enabled at any FSB.
That said, I've tried with all those options disabled and booting at 201+ FSB. I can't even get it to post above 211 fsb.
I just set performance mode to standard and boot at 201mhz and work my way up from there. I'm using the 1009.004 beta bios and this works for me. Memory divers aren't important at all.
With PAT enabled I can't go for example past 11*241 but if I disable PAT I can do 260*11 with my 2,86ghz Dothan, I have this 241 limit at all Dothans. Strange thing PAT also gives me limits at all other dividers and probably too if the chip runs at a higher fsb with the 13* multiplier but I need other cooling to test that.
I think you should use 865 tweaker and try out all timings. Have you done this already?
Edit: Correction. Bioses DO NOT change my overclock. What dropped my overclock 100mhz was changing the jumper on the ct-479 from 400fsb to 533fsb.
I'm starting to suspect the ct-479 more and more, and will probably replace mine.
Can you link me to 865 tweaker? I'll try it but honestly I highly doubt changing timings will effect anything. I'm running much much much looser than I've run on this board with 478 procs before.

Me too, it is very strange that PAT is limiting me at all dividers. This can hardly be a motherboard issue. I think the CT-479 has some bugs and we need a revision 2. I can't believe replacing the CT-479 will make much of a difference. This device is so simple that there can hardly be something not correct in the device. Maybe there are some bugs but this would effect every one and every device.Quote:

Guys, just to clear things up, if I get a "vanilla" P4C800, would it have the same o/cing options and performance as the P4C800 (-E) Deluxe (assuming that everything else works ok?). From Asus website, it seems that in chipset features these boards do not differ at all, but I recall somewhere people did not recommend the "vanilla" P4C800 (couldn't find that to confirm though)?
You won't have the MP option in Bios as P4P800SE & P4C800ED.Quote:

Since you prurchased a P-M740 it's not a problemo for you ;)
As i posted it at the dothan overclocking thread.. take off all the jumpers from the ct and youre oc will be much better.. mayb this is the problem solving with pat! will test it this evening.
Never imagined it would be so easy :woot:

still learning to use dothan power :stick: and on original ct-479 cooler :(

Never dreamed achieving less than 30s expending that much

now get that multi down and fsb up! :)
He might be at his limit with 169FSB and a 7x5 CPU.Quote:

you could still flash the p4c800e-d bios is a 'vanilla' p4c800, right? and have the MP option?Quote:

The MP option is bios depended. If your bios doesn't have the MP option, you can't change it. Basicly every board support changing MP.Quote:

What I've tried:
P4P800SE bios on a P4C800-> MP option works
P4C800ED bios on a ^^^^^-> MP option doesn't work at all.
As you can see even flashing a bios with MP-option doesn't always guarantee the ability of changing MP.
yes you can do this but you lose your onboard lan as the p4c800ED uses a different type than the vanilla p4c800. I tried the ED bios on my vanilla p4c800 to get the MP option but when I tried to save with the changed MP it just seemed to revert back to default of 12 so I flashed back.Quote:

I'm trying to hotflash my P4C800-E Deluxe bioschip on my P4GD1 motherboard and I'm getting ASF Signature not found when I try to flash with the P4C800-E Deluxe bios.
Do anyone got a clue what to do?
I use the /n /pbnc switches aslo.
Anyway, decided to skip the P4C800 (-E, whatever), and go straight to P4GD1 :D
