its the mobo problem.last time i faced the same problem but now with my MSI mobo its doesnt fluctuate as much already.

welcome to the club and yeah booting up from sata hdd is much faster compared to pata.

of coz it will be faster in sata. transfer rate is higher ma. 133 vs 150. but for me i wont feel any big different. old man is a bit less sensitive to tiny things. wakaka

@Ryu00717
welcome to the club. Raymond will be off for few days, when he is back, you will see your name in the list.

@Pengster
seems that p4p800x is very not stable board when oc. i didnt blame her coz she is just a little mobo build for budget tight user.

Does anyone know the reason for this?

When I do stress testing using Prime95 Multithread Edition, with the Large FFT test on, one thread would always fail within 30 minutes where as the other thread would go on as though nothing happened.

My processor is stable, raising Vcore did not solve the problem, same goes for the memory, which is also stable. Now currently I'm trying to raise AGP voltage to test, but I hope someone here has this similar problem and share their views on it.

I also read that increasing AGP voltage might fry ATI cards, and I have changed the chips that regulate the voltage to a cheaper variant because I accidentally ripped one out before.

All the more for the card to burn.

wah ... the old thread still got reply aaa?? can ask nelza or the mod to close la .. quite confiusing ... anyway i've oredi loan sum fund from my bro to buy me strider 400w as he been to lowyat shopping his new AMD rig ...can't wait to plug it into my rig and play what ur guys playing ...

what do you think? old is gold ma...

seems sang_karim cant wait pushing cpu high high liao. wahaha...

@Colin
even stress with gromacs core and blend can pass but failed in Large in-place FFTs?? 1st time i know this, normally i stress with core and blend only. hmm......

yeah its not stable at all.(to me lah lol) now im currently at 145FSB with my MSI mobo.i couldnt even reach that with the previous P4P800x

Yo pals... Here i am! Having same problem as u do.. That happened to me when i go over 3.6Ghz. Gromacs stress i face no problem. But when go for Large in-place FFTs sure failed within 3mins. Seems like the procs can been stress and not the memory for my system. My vcore was set to 1.85v, vdimm 2.85v, vAGP 2.6v. Still having the same problem.

P/s: Btw colin, which priority are u running on? Mine was on 10. Full stress..

I run mine at 9.

I'm guessing it's a heat related problem. I'm gonna get my new fans soon, then I'll post back results.

Prescott with 1.85V also cannot pass ah?
You need to go water cooling adi

or probably you got 1 of the unlucky procs loh......can get high speeds but not able to stabilize it

My computer suddenly shut down by itself.. well...... not really shut down completely, the cpu LED is still on. Izzit my power supply problem? Check this out

Temperatures
Motherboard 37 �C (99 �F)
CPU 35 �C (95 �F)
Aux 45 �C (113 �F)
Seagate ST3160815A 39 �C (102 �F)

Cooling Fans
CPU 3125 RPM
Chassis 2637 RPM

Voltage Values
CPU Core 1.52 V
+2.5 V 2.61 V
+3.3 V 3.42 V
+5 V 5.19 V
+12 V 7.10 V <---- is this normal?
+5 V Standby 5.13 V
VBAT Battery 3.39 V

Aiyak.. Sorry! Typo error la.. It should be 1.55v.. By then.. See my new screen! My new result! Hehe.. Guess i found out what stopping me for go beyond 3.6Ghz liao.. Now running at 3.67Ghz! Near 3.7Ghz! Guess i didnt supply enough vAGP last time thus is makes me cant go beyond 3.6Ghz! Tried few time with 1.6v vAGP really makes my system reboot or hang after 30secs priming with priority 10 Orthos. Guess when hit high speed, the north bridge need more juice from PSU in order to maintain and stabilized the system. Seems like is not my D43 and TCCC ram fault. Blame the wrong part..



Setting as below:

Running at: 3.67Ghz @ FSB245*15
RAM ratio : 3:2 (Well.. havent try on run at 1:1 thou, but can archived 3.67Ghz with 3:2 count ok already for me. )
vcore: 1.5375v (lower down from 1.55v)
vdimm: 2.85v
vAGP: 1.8v (Taking rise with max up the vAGP and i got some surprise! )
Full load: 56-57'c (Kinda high for me.. Will try to adjust my cable management agian.. )
North Bridge: 42'c
GC: 58-60'c (Jumping up and down thou.. and i didnt OC the card yet!! ! Max vAGP really heat up my GC)

Result:

Satisfy with this result. 3.8Ghz on the way! Although prime for 2hrs only but it can last so long without restart really make me happy like picked gold at road side!

colin, if u're dare enough like me. Try max up ur vAGP and try prime agian. I bet this will be something good happened on ur rigs. See my result above..


Pals.. seems like ur 12v rails wasnt that stable. What PSU ur using at the moment?

12V running at 7+V is nor normal at all.

ever clear cmos?

might be reading error? Haha.. Try clear ur cmos and see hows the things go. Btw, what mobo are u using ac_N1?

+12V that low is really dangerous
All your drives will be in danger....

Currently using PowerLogic 450W 225W true power psu.

i tried clear cmos edi.... doesn,t help

Using shuttle AV49P mobo.

Guess time to find myself a new psu

hehe...u all are warm blood ppl....
i'm touch....
hehe
yeah
i'll be joining the big family.....

Added on September 3, 2007, 9:07 amno...i think the problem is ur cpu fans din work...
coz i have it b4, suddenly shutdown
then i check the cpu fan suddenly din work....
jz check it, and now i change it, no shutdown occur again...

wah .. at last can past 3.6GHz .. congrats bro vAGP : 1.8v ... will it fry ur gc if run for daily use?

Haha.. Hm.. Wanna change my gc cooling liao.. Getting a Zalman Fatality FS-V7 from a forumer here soon. mighyt COD this week. Btw, i havent tried with 1.7v vAGP yet.. Haha! 1.8v heat up my gc for around 7'c..

@flyon
congrates, you are the man! gogogo~

i think you can go beyond that la. go 3.8GHz!

btw, ever try 245 with 5:4?? for me, i use 3:2 to test out the max speed for my cpu only as 3:2 really suck.

Haha.. Duno yet.. Cos was running on 3:2 last night tats why can hit that speed and prime for 2hrs plus without problem lo.. Havent try 5:4 yet.. But i set the ratio back to 1:1 and the system can run without problem. Tonight wanna try prime it and see how. Will post some screenie agian.. Hehe! Btw, 1.8v vAGP really heat up my GC le.. idle can hit 58'c.. Waiting for the Zalman Fatality FS-V7 now..
