i using air zeon 450 watt psu. i know it is not branded but it is quiet and better than my aopen 300watt psu before. Normally it fluctuate 0.05+- for vcore. as for 12v it wont stay below 11.5v. I hate that my mobo always report higher than what i set for it in bios. like i set 1.45v it shows 1.52v in cpuz. it will drop to 1.45+- when i stress it but fluctuate as expected.

Pengster, your MSI mobo is more stable than current p4p800x? i wonder that all 865 mobo having this issue. sometime i have to stress the cpu the get the exact vcore reading. idle vcore reading is crazy high. i set at 1.5v it sometime can up to 1.6v in cpuz.

Last time i blame on cpuz reading is inaccurate but mbm5 return me almost the same result. but anyway, system is stable. Just i dont really feel nice as i know that fluctuate voltage is harmful to all components in pc.

i'm an MSI mobo user,i found out tht its hard to overclock and performance only so so.when it POST it sometimes stuck at MSI logo screen for sometimes and i need CTRL+ALT+DEL.same wif one of my fren.both of us were using MSI NEO2 865 PE.

i do agree tht ASUS mobo is good for overclocking during my experience wif my S370 Pentium3.even wif stock config,the mobo has already overclocked ur processor and RAM  by a small margin.thts y ppl say ASUS board has good performance. but then during the time i bought my P4 rig,only MSI has 8X AGP support mobo in my area.i'm was staying in Ipoh back then.thts y i bought MSI.

anyways, u guys think such device call "Auto Voltage Regulator" will help abt voltage fluctuations?

Good questions,i'm also looking for this answer.AVR can regulate the voltage first before sending in to our PSU.Stable voltage can let the PSU deliver better supplies to our deivces,but don't know is there anyone here using the AVR or not.

dont know yet, now downloading 3dmark03, 05. hmm... hope my cpu wont bottleneck it.
@k!nex
ops, i thought yours is 3ghz. if your 2.4C can get to 3ghz, then mine really far behind. haha....high fsb and HT helps alot. 

1:1 will be the best performance as ram and fsb are synchronized. even at lower clock it can outperform or on par with 5:4 setting on higher speed(ofcoz not too far the different like <200mhz). Really not bad for a pc2700 ram perform at 221. what is the chip anyway?

add vdimm may help to increase the stability. hows the cpu temp at that speed?

Hey, any of you are still using the stock HSF? Or a 3rd party ones?

Thanks for the warm welcome. Actually it can go beyond 2.8.

I've tried once, with looser memory timing and some voltage bumping, it can reach 3.4~3.5 no problem.

But since I'm using all stock cooling solution, 2.8 is good enough.

Well, a modified BIOS could increase overclockability on a motherboard by editing romsip tables, unlocking hidden options, etc. That was for the NForce2 series boards though.

I wouldn't mind an E6600 if it was free

The main thing of a modded BIOS is to unlock hidden options. Stability terms is depends on your overclock settings and skills

kabukawie : Most of the programs will fully utilise the 1mb cache of the prescott.yup its true that high FSB is better, but not much of a difference in Sandra benchmarks and SuperPI, those more towards raw clockspeeds. PCMark likes FSB as well as 3dmark

nice words from colinwong89. i will welcome free E6600 as well.
if you have the cash then there is no harm upgrade to c2d. but it seems the price will drop pretty soon when the new chip is out.
agreed. sandra likes raw clockspeed. 3dmark/pcmark loves high fsb and tight memory timings. But what i read from some old reviews that northwood and prescott with same 800fsb perform neck to neck at the same clock speed. Just the heat from prescott is 'superb'. Ofcoz, if proper cooling, mobo and ram is provided, prescott can  go beyond 4ghz where northwood hardly reach 4ghz due to its chip's limit.

yeah same here i m even willing 2 sell off my 4 mths old k800i just 2 pump more cash 4 major upgrades but at the same time i still not willing 2 depart the k800i wo so should i sell it off or not ah i wondering 4 days dy

wa....it seems that more 478 user shifting.

damn, my mobo doesnt support 7300gt. waste my $ only. when plugin, the system become not stable even oven stock. At 1st i suspect psu not enough juice, borrow a 500w true power psu still same. reinstall windows 3 times still same problem, tried 3 different forceware, change new ide cable, switch ide channel and tried boot from sata/ide, reinstall cpu, take out all pci card, flash bios etc. even i rma the 7300gt 1 to 1 still having the same prob. Haiz....wasted 2 weeks to troubleshoot.

when put my g3 in everything stable even with oced cpu. I really have phobia with new gc already.

yalo, maybe mobo is dying liao...   maybe last time the 9800pro spoiled have more or less leaving some bad effect to it. weird things is that the g3 i use is fine. not a sweat al all.   
what to do...use till its last drop finish lo.... i didnt see there is any cap that leak or gain fat. Maybe some tiny damage already on the mobo. As lng as it dont give me any prob, running on stock also will serve me well already.
mine more syok oso useless, my fsb not even pass 200. Unless i have a 800fsb cpu like C or E. i wont feel any huge performance different with few second 1m superPI in real performance. Dont really care already. just hope that it can last till next year at least. 

Those who are OC'ing your P4's whats your load temps?

I think before migrate to C2D ,we can still survive for another 3 years.

@pengster
What graphic card are you currently using with your P4?

@kabukiawie
Sleep in the dustbin? I smell a new motherboard coming up

Underclocking might save a lot of power and might make your processor last longer, but I always prefer to run my PC at max speed.
