My CPU underclocked itself, HELP?

[Nerd]

I have a T-Bird 850, and I tried connecting the L1's and the L6's. It wouldn't boot. I erased the L6's and it booted.

Now when I set it back to the default settings it says my chip is a 800 T-Bird.

WTF happend?

Try redoing your L1's or erase them too and see if boots at 850 like its suppose to.

i'm not trying to insult your intelligence or call you a newb, but are you sure you have an 850? check the marking on your chip and make sure you do. and also reconnect your L1 bridges 🙂

 

[Nerd]

Yes, I'm sure. I've had this chip for a while now. It says 850 on the chip itself, and it also used to say 850 in BIOS.

what motherboard do you have... motherboards with the KT133 chipset have 'issues' u know?

 

[spoma]

what do the kt133 chipsets have problems with?

 

[Boonesmi]

L6's have to do with multiplier ratio, connecting them in part (along with l3 and l4) tells the cpu its an 11x multiplier. so closing all the L6's could cause problems

L7's increase core voltage

i had a 900tbird for awhile, when i was connecting the bridges for the first time it came up as 750 every damn time. i dont know what your bios allows you to do, but try setting the multiplier to 8.5 and fsb to 100 (my board has some option like auto detect, so set it manually) then see if it will read the correct speed. if that doesnt work, just clean the markings off and try again, you might just have a little overlap.

Here is a good guide to overclocking without BIOS support:
