[help] Cpu Speed Resets

when i boot up, i find that my cpu resets to the default 1250 mhz speed instead of the normal 2000+, 1.66 ghz speed. i need to go into the bios and retoggle the speed setting, then save again.

i don't think it's a battery problem because:

1. i just changed the battery a few weeks ago when it started happening and

2. the other bios settings are correct (i can tell because they're not set to defaults).

it only started happening recently (i.e. just a month now).

specs:

amd athlon xp 2000+, 1.66 ghz

abit nf7-s, bios 19

anything else, please ask.

i've also tried setting the speed manually and connecting the atx12 connector, but still no go. could it be a power issue?

relevant info:

antec 350w psu

mbm info:

core 0 = 1.55v

core 1 = 2.61v

+3.3 = 3.18v

+5.0 = 4.92v

+12.0 = 11.49v

-12.0 = -11.94

-5.0 = -5.15v

12v rail is within the 5% safety margin and i have no stability problems whatsoever. i might have to buy a new psu to resolve it, but i'd rather not, since the only problem i'm having is a resetting fsb (set to 100, not 133).

any other suggestions? thanks.

Mabie your bios is going bad or soemthing. One thing you might want to try is reflashing it. Are you shure a jumper isnt set over the reset plugs? Your voltages look fine, and i doubt that would be causing the problem, if anything you would be seing resets because of a drive or cpu failing or something. You didnt install any windows on the fly overclocking utilities did you?

haha, i just checked, and it's actually a 300w psu, not 350. don't know why i thought 350 all this time.

anyways, i'm not really too eager to flash it. i've never flashed before, and honestly, i haven't had any bios problems at all. everything is fine, except for the resetting fsb.

secondary maxtor drive is fine, and the primary seagate drive is new (if you remember my other thread about my loud drive), about a few months old.

i don't overclock at all, so i didn't install any of those utilities. if i were to overclock, i'd do it through the bios.

cpu could be failing, i suppose, but once i'm in windows with the correct clock speed, everything is fine.

Well don't flash it... I doubt that's the problem. You sure that the time/date isn't getting reset as well? Sounds like a battery problem eh.

that's one of the first things i checked. time/date (and all other settings) are correct, so i know it's not the battery.

some people on the abit forum were saying that the margins should be around 2%, so i might consider a new psu. my gf is trying to persuade me to pick up a mobile chip, so we'll see about that.

i'd like to find out more before i go around spending money, though.

Your GF is persuading you to get a mobile chip? Wow, she must know her stuff!

On the mobile chip note, I got a 2400+ -m, OC's so well, I'd recommend anybody to get one.

I have an Antec SmartBlue 350W, and I get 12.04V on my 12V rail and -12.68 on the - rail right now but I've seen the + do 11.75V sometimes in the past. That's never been a problem.

Could it be your DDR/FSB ratio thing is funky?

I have a NF7-S rev2 too, you should manually set your multiplier/FSB (there's an option in the BIOS called "Use custom settings" or something like that).

I seriously don't recommend you flashing the NF7-S because before this Abit I always used Giga-byte with dual-BIOS, it's all good if something messes up.

The day I got the NF7-S I tried to change settings in teh BIOS and while it was saving I cut the power, the thing just died. I had to ship it to California for RMA .

well, she did build her own computer. but i was telling her about the mobile chips for a while now, so she's trying to get me to get one (maybe to stop me from complaining).

anyways, the 12v rail looks fine to me, so i don't know if it's causing the problem.

ddr/fsb ratio is set to auto, and the cpu clock speed is set manually (user define).

i'm going to try disconnecting some items to see if it fixes the problem. my psu could be sagging, but i highly doubt it.

i am already convinced that youve got a good GF man

well, after years of complaining about her crappy gateway computer, i finally convinced her to consider building herself a shuttle. i helped her choose the parts, and over spring break, she put it together. she wouldn't even let me touch the parts because she wanted to do it herself.

anyways, i'll try some more tests, but i've had 2 successful boots (knock on wood). hopefully i can figure it out.

an update.

it worked fine for a while, no resets, but then i left my computer off for quite some time (about a day?) when i went to stay with a friend and the problem came back.

as soon as i got the problem, i went to check the health status and the voltages looked normal, so i don't think it's a power supply issue.

could it be the cpu?
