hi lads.....
i have my dothan 730 running rock solid at 2.94ghz on water at 1.6vcore with asus adapter and a p4p800 se.
super pi in 26 secs...... :banana:

Yea, that is sweet...
Love to see the setup :D
looks like im haveing some trouble with my setup...
p4p800-se
p-m 730
512mb ddr400 kingston
im going to reflash the bios but after changeing out the p4 to the pm i only have options to 1.6v in bios and asus probe reports 1.58v in windows i can run 2.4ghz but going to click on startmenu and restart. i get blues screen even though superpi ran just fine as well as prime95. I have set in bios to boot the cpu @166fsb. i can do this with the voltage set @1.55v which reads 1.53v/1.51v-idle/load. I tried to u wire mod for 1.65 but when i check in bios it still says 1.6v and the lowest is now 1.475v. I have undone the uwire mod...
*edit*
seems having the hdd's with the adapter plugged in was the problem.
the 730 now boots into windows @ 2.4ghz @1.6v (bios) underload its 1.55v.
tortue test in prime95 fails @220fsb but its currently tortue testing @216fsb.
Is a better HSF (xp90) really going to make that big of a difference? load temps now are only 52-53c (stock asus cooler).
thanks guys!
The xp-90 will make a big differance my m730 at 2.8 never gets into the 40's with room temp of 22c.

m730 1.6 5ssfsb @ 233 fsb bios shows 1.53v but i do have vid4 ,1 and 0 u wire mods dont no if they are working but it should show 1.64v :confused:
xfx 6800 gt
super pi 1m best run but i cant do it again i can get 26.1

3d01 with 6800gt running at 400/1100
http://www.ljsnet.co.uk/3d01-2800oc.JPG
if i run at 410/1130 i can break 30k
this is going to be my new rig i am selling my p4 2.8c.
My ram is holding my back this is about it's limit at 2-2-2-5 but i am happy with this setup at the moment.
I do plan an removing the u-wire mods to see if it runs the same as i could not get ovet 230fsb on a p4p800-e this will go to 235 before the cpu locks up.
I did run it at 11x and ran the fsb upto 250 ish no problem but with memory at 200.
did you check the bios to see what options where there after the mod? i did the same thing with my 730 and the voltage options where still the same 1.6max in p4pse. cpuz still read the same voltages at idle and load. wish i could get past the 220fsb wall im at.. might be the kingston ddr400 cas3 doing it...Quote:

i then tried with p4p800-e bios 1007e.004 on the p4c800 and i can select from 1.5 to 16.v but when i select 1.6v it still shows 1.536 as the vcore.
I think i will remove the u-wire mods and test that. The strange thing is that i used to get the full range of vcore options from 0.7v upto 1.6v the first time i used the m730 but now only 1.5-1.6. I fixed this once by booting with a p4 chip and defaulting the bios and then putting the ct-479 back but this time it didnt work.
If all else fails i will do the vcore mod on the p4c800 to get to 1.62v as macci said this is the sweet spot for this chip.
as for your 220 fsb limit have you tried running your ram at 266 and the m730 at 200fsb this should eliminate any ram issues and allow you to find the true limit of the cpu. On a p4p800-e with 1.6v i could not get to 2.8 but it will on the p4c800 maybee the mods are actualy working.
One other thing to try is putting the ct-479 power connector on it's own dont share it with anything else thats what i have at the moment that could be whats given me that extra few mhz over the p4p800-e.

Its @225fsb prime95 2048k tortue test...but with the slower timings needed for the ram my superpi 1m time is the same as @ 2.6 with slighty tighter timings. i did what you said for ram @266 but cpuz and the clockgen still said ram was running @ddr400. Using clockgen to get 230fsb was an instant freeze in windows. Not sure if i need more volts or better cooling.
Got a Thermalright NB-1 northbridge HS/F for the P4C800E-Dlx, it's a noisy little bas&ard, hehehe...
Hopefully it'll help me OC a bit further!

Charlie , can i ask you for pic on this NB cooler i have the same one , but looks a little bit cheap , and very hardly to imagine how to mount it :)Quote:

after doing some low voltage testing... my 730 will do 2.4ghz with p4pse bios set to 1.325 and asusprobe reads 1.31v/1.29v idle/load. quit nice @ 38c load temps and its hot in tx.
hehehehe...730M does 2700mHz easy and performs equal to or better than FX55 @ 3ghz... at $140
And P4P800 can be had @ $50 and P4C800 can be found at $80...

I just removed the vid4 , 1 and 0 u-wires and set bios vcore to 1.6v. The bios still showed vcore of 1.536v in system monitor / cpu z and asus probe.
I set fsb to 230 in bios and booted to windows ok but it reset when i set the fsb to 233 with clockgen so i guess the u-wire mods are working but just not showed in the bios. is there anyway i can get an actual vcore reading with a multi meter on the p4c800 or ct-479.
edit: i put vid4 and vid2 u-wires in for 1.64 vcore bios showed 1.568 dropping down to 1.536 under load. i could run at 233 again but maxed out at 2825mhz same as before with vid4 , 1 and 0.
i would like to test just how much vcore it actualy has.

I don't know what caused it but no amount of reflashing and clearing the CMOS and swapping out the CPUs seems to do anything. Kinda annoying really.Quote:

this sounds like a bug with the bios... wth is asus so slow with bios updates now? they took away 1009B(p4p-se) and gave p4p-vm a new one... :slapass:Quote:
