hi guys, i have a p4p800-x and my system wont cold boot whenever i set the vcore to above the proc's default. I'm suspecting the crappy PSU (icute 450w), but need confirmation before i get a new psu as i'm almost outta $$$ already... so can anyone
confirm this? thanks

how bout other setting? jumper?
try borrow psu from ur friend and test it...

hey thanks for replying...
unfortunately all my friends are using worse PSU than what i have. Basically i have a celeron D 2.4@3.6 E0 stepping not prime stable unless i up the voltage to 1.475v (i know many E0 cel D does 3.6 at stock voltage, could it be my PSU?). At this voltage everything runs fine... but when i try to restart the com it wont start. A cold boot wouldnt happen either..

change ur psu...
previously i also using celeron d 2.4ghz, running fine at 3.6ghz @ default vcore..

there is a case where i use icute 450w psu, highest i can go @ default vcore is 200mhz
when i change to CM real power, i can go 211mhz...

borrow thread

I got a similar setup celeron d 2.4G and p4p800 dlx. my celly is running at 3.15G default voltage (175 mhz, DDR350). I can't get it above that no matter what voltage i pump in. what's the problem? someone plz help..

how bout mem divider?

yeah... make sure the mem divider is set to 1:1 (i.e 333) and not auto as the mobo assigns a 5/4 divider for auto.

it's actually 1:1 already - RAM at DDR350 only

mind list out ur spec?

pretty basic

Celeron D 320 (2.4Ghz)
Asus P4P800 Deluxe
2x512MB Twinmos SP (UTT CH-5) - does 2-2-2-11@240Mhz@3.3V on my old nf2 board
Antec 480W
SLK947U + 92mm Delta

how much u give for vdimm? i only know p4p800 deluxe got 2.85v...try set to the max...
abd did u lock the pci/agp bus?

yeah, only 2.85V. i know the Ch-5 requires a lot of voltage. but this is just DDR350 at SPD timings and it still wouldn't budge from 175Mhz. in fact i can even run on the most aggresive timings with turbo mode at DDR350. but at fsb 180mhz (ram at DDR360 SPD), the system won't even post.

have u guys update to the latest BIOS?...

just curious.. what do u mean by cold boot?

Cold boot is a situation where sometimes your system refuse to boot, eventhough your pc's stability is good. It may need a few times restart to make it turn on and post.

ahhh... ok..thansk for the info

Hmm you know I have this occasionally with my 2.4C on a P4P800-E Deluxe.
Sometimes, maybe once in 3 weeks, I will come home from work, turn on my PC and everything comes on, but no POST, nothing. THen I turn off, turn on again and its fine.

I always wondered why its so. I was thinking the mobo is slowly degrading from running at 250MHz FSB daily.
