1Ghz athlon only running at 800?!?

hey,

My computer is not so new,
-asus A7V motherboard
-384mb 133mhz sdram
-1000Mhz Athlon thunderbird
-20gb quantum fireball
-asus v7700 gforce 2GTS 32mb

heres my problem, For the longest time i have been running the computer just fine with default settings, and everything was fine, till one day out of the blue the damn thing boots up at 800mhz... So i fiddled with the settings (which i know VERY well) and nothing would work... so i just left it for a while, because i didnt really care that much! But to my suprise a week later it started running at 1000mhz again all on its own with no tweaking! this was fine untill recently when it happened again... back to 800! so now im getting royally pissed ! Back a year ago or so i tried to overclock it because that was the big thing with these chips (still is by the looks of it!) and i did the old pencil on the chip trick and it more or less didnt do much.. i had a pretty unstable chip we will say... so i set all the motherboard switches back to defaults and left it to be! then about a year later is when all this stuff started happening!!! It's an underclocking mystery......

can anyone help me??

much appreciatted

Hmmm,

Stock
7.5*100=750

Is this your attempt to overclock?
8*100=800
8*133=1064 roughly 1000, although I thought the bios would recognize this as 1050 ?!

Check your FSB in the bios. Maybe it's just the battery on your motherboard that is dying and it's running your bios at defaults (100Mhz) when it's having problems.

ya thats probably all it is, the battery... seems like a possiblility.. ive only had the mobo for maybe 2 yrs or so though.. can it die that quickly?

- As for the lead on the chip, I erased it ages ago. so thats not the problem.

my system: athlon 1Ghz t-bird, 384mb 133mhz ram, asus A7V mobo, asus v7700 gforce 2 gts 32mb, 20gb quantum HD,mx400 sound, 17" monitor, altec speaker/sub.

Isn't there an option to on the A7V to set FSB by jumpers or go jumperless? Maybe the option jumper is making intermittent contact.

Ya its all set to jumperless, so it should use the chip's default setting multiplier of 10. the fsb is 100mhz thats what it's designed to run at. so 100x10= 1000Mhz default right? thats how its set up, and its been switching AUTOMATICALLY! like i havent touched it, and it booted up one day at 800mhz.. dust hmmmm.. maybe.. all good suggestions.. ill look into it..

thanks alot guys!

When its 800, check something like wcpuid and check the multipliers and stuff. That way it would be easier to find out whats being changed when it is from 1000 to 800, the multiplier or fsb.

OK, thanks. I didn't realize both versions of the A7V (with and without switchblocks) were sold at the same time. I do remember that the engineering samples that the reviewers first received had the switchblocks. I also remember that people were complaining that the switchblocks were absent on some boards and that there were DIY fixes for this.

I could be wrong but I also thought that the early A7V did not have the option for Multiplier and FSB adjustments in BIOS meaning jumper free operation was not for overclockers. I thought that true jumper free operation (including overclocking features) didn't appear until later revisions.

I do remember I chose the Abit KT7 over the Asus A7V because the KT7 was completely jumper free plus I didn't want to get stuck with one of the A7Vs without the switchblock.
