My run after revival mobo.
1.6 Dothan 400 fsb
P4gd1
2x256 Twinmos Bh5
stock cooler
change multi with > Eist
change fsb with > clockgen for Asus P5Gd1 or setfsb for P5gd1
cannt change mem ratio at bios, only 266 or 300 setings or auto
change v core in bios > yes
max fsb cca 150 fsb with clockgen , working on 16x144>2340 @1.35v *default
when i setup 10 x 200 system freeze
Any ideas for running at 200 fsb alias 400 ddr ?
thx
i use ASUS P4C800-E DELUXE (all mod=i also remove the mods but dont help)
corsair 512x2 pc4400
antec 550w (FOR VAPO AND ULTRA) +enermax 425 dual rail (FOR MOBO AND PLATIER)
200g sata
36giga raptor
i try 320ram in 200 fsb= dont work
temp=cpu= -28c!!
i can boot with 198 fsbx13 =2580mhz and then with eist to multi to 12x198 and then with clockegen i can 215x12=2580mhz!! i cant goo over that no even with 1.6 volt!!
i dont do the u-wire bicuse i can get 1.6 volt with the bios!!
thanks
it could be you have a poor cpu that wont overclock. you are able to run over 200fsb with multi if 12 so thats not the problem.
even though you have vcore of 1.6 in bios i bet it drops down to 1.55v like the p4c800-e deluxe i have next to me.
i am using the new 1022ed.003 bios on a pc4800-e deluxe and it is locked at x6 in the bios. Vcore works ok but the range is 1.5-1.6 and at 1.6v it runs at 1.568-1.55.
i have reset bios defaults / used the afudos that came with it with /pc as in the text file also used the older one i have with /n /pbnc but still locked at 6.
lucky eist or cpumsr can change it in windows.
i tried running at 6x250 with memory at 320 but it wont post with the stock cooler and vcore at 1.6.

my 730 did 2.94 ghz with much higher fsb ratings so my benches are suffering too!
any advise welcomed!
gordy! :rolleyes:
if i will do the vid4-vcc pin it will work?
also can some one give me agood photo hwo to do this mode to the cpu?
thanks
ok!
i do the u wire (1.55) and still have problems to over 2580 mhz!! why is that?
i see guys with this 740 dothan that go over 3400 mhz!
what i need to do to goo that to?
thanks :toast:
you REALLY need to study this better... no offense, but you ask questions like you haven't read the threads. 3400mHz is on LN2, a LOT colder than a Vapo.Quote:

who it can be that i cant rich 2600mhz? 200x13 in the bios?
edit:
my dothan steping is sl7sa!! this is good?
@charlie
wtg man nice to see you hit 3ghz with your new cpu :toast: :woot:
They have found quite annoying combinations of settings to put in the bioses at Asus, always one piece missing from the puzzle preventing overclocking. :) Maybe they are still testing something and trying to figure out if it is safe enough to allow overclocked usage. And when they see it's all safe they will release bioses with full options. :rolleyes:Quote:

I would understand it if he had temp problems, but temp does not seem to be the bottleneck here. Please correct me if I'm wrong.Quote:

Is vdrop a must on the P4c800 e DLX?
Temps doesnt make a wall like that.Quote:

I mean, find the max for the components.
Whats your mem max?
Whats your CPU max?
Whats your FSB max?
Do some methodically testing to rule out components. To me it sounds like either a bad CPU og tricky memory. OR simply a misunderstood way of getting some juice out of these Dothans...
I would pull off the vapo, work on getting above 200FSB on air with low multis (charlie managed to get a 3GHz clock though booting below 200FSB...)
Otherwise sell that multi 13 CPU and get a 730 (multi 12) instead.
maybe its your sata disc ye-3333
many thanks to STRYG and VANOVICH :)
can someone please post a "newbie" detailed explanation of the vcore mod and vdrop mod?
The 1008 bios is not multi unlocked either.Quote:

in that case, i gonna vmod it anyway
with 1.6 in bios+v-mod you don't need any more the pin mod...nice!
I have to say i am getting a little frustrated with the dothan.
I just finished doing the vcore/vmem and vdroop mods the a p4c800-e deluxe rev2.
setup a stormg4 water block and 2x thermochill 120.2 rads with mcp650 from the p4 i used to use.
the new geil pc4000 arrived today so i can run at 250fsb no problem
set bios to 1.6v 230fsb still have multi mocket at 6 but that is ok i can just set it in windows.
boot into windows ok as normal cpu-z confirms i am running at 1.64-1.62v
set fsb to 233 and the system just hangs so water cooling and 1.62v made no differnace i still cant get over 233 any more.
just trying with setting fsb to 166 in bios and ram at 200 see how far i can push that.
it could be the bios causing me problems with the 6x multi but i dont think so.
the only thing that's left for me is get the temps down with a water cooled pelt or somthing like that.
So, at this point wich board works better with Dothan CPU's. OC's better, is more stable, has better options and both multi and fsb can be changed...?
Any suggestions?
I did read the first post from top to bottom, but live experiences is what I need :D.
i have my old p4 2.8c running again @ 3569 with the new geil pc4000 at 255 2.5-3-3-8 2.95v
first super pi 1m againts my best dothantime at 11x233

next 3d01 with a 6800gt with stock settings
p4

and dothan
http://www.ljsnet.co.uk/3d01-2800.JPG
The p4 is so fast in windows everything responds instant when windows loads but the dothan is slower you can tell after running one after the other.
but the power of the dothan side is impresive ..most impresive
It's been said before, but I'll just reiterate...
You need a 730 or a 740 to run them on AIR the way they're meant to be run. I've tried for 2 days to get my 750 to load windows on AIR (even my Zalamn7700Cu) and it just ain't gonna happen. Once in Windows it'll run sPi 1M at about 2750 on AIR, but won't load windows at 2814 (201fsb)...
So just to remind peeps... 730 or 740!!!!!!
EDIT!! I did manage to get it booted/loaded on AIR, lol, but by resting the evap of the autocascade on the edge of the heatsink for 10 minutes and THEN flipping the switch, hehehe...

It seems even the 2600 that the 740 requires is a bit chancy. So the safest bet is the 730. And the 730 seems to overclock just as well as any other. Quite often people will buy higher rated chips to get the better binned pieces. But with these it doesn't seem to matter much.
yup...
Only bad thing about the 730 and 740 is if you're competitively benching with phase/DICE or LN2 and you wanna' run 250-260, 1:1...
The 12 and 13 multi's may leave you a bit short.
