Overclocking XP1600+

Hey again - its me :P

Yep - my Athlon XP1600+ is giving me problems - it works fine upto 1501 Mhz
(but only at 1.85v) on a 143Mhz FSB, but it will *not* go any higher. 145Mhz
Causes it to fail post, and i need to turn the system off, wait 20 minutes,
turn back on, and quickly change the FSB back to normal before attempting to
boot again.

The board in question is a Gigabyte GA-7VTXH w/KT266a

Cheers

I used to get 1750@140 from a Pal 1700 - so try raising the multiplier.

1501MHz? If it's a Palomino consider yourself lucky ;-) That's about all I
can squeeze out of my XP1600 on a SY-K7VTA Pro.

Erm - well its a Palomino core, and isnt it impossible to change the
multiplier? arent they locked? If it involves chopping the cpu around - i
dont really want to chance it.

No chopping, just a bit of sellotape, thermal grease and conductive paint
(apply with a razor blade).
It's quick and easy (if you use thermal goop not glue to pit fill).

Hrm - the question now is a) how? and b) where do i get the stuff from,
without the aid of a credit card (cant have one for the next 3 years) in
europe :P

Some overclockers have used conductive paint from a rear window defroster
repair kit. Also some craft and hobby shops carry metallic paint. The
plastic (Scotch) tape and non-conductive thermal grease should be pretty
easy to get locally. You could also try a needle using the small hole to
hold a small amount of the conductive paint. A verrry small needle :-)

I'm just too lazy to pull the motherboard for cpu surgery on my back up unit
which will be replaced when the new mobo arrives Wednesday. Like I said
1500MHz is about tops on an unmodified XP1600 Palomino.

The good news is if you mess up just clean everything off the cpu and try
again ;-)

Good luck,

FRH

The problem isn't the CPU, it's the PCI bus. I ran my 1600+ over 1800MHz
with 1.85v. Ran it 24/7 for months at 1733MHz. But I didn't jack up the
FSB (at least not too high), which jacks up the PCI and AGP buses.

Oh i know that - the problem is, that on the 7VTXH, you cant do anything
with the AGP or PCI bus clocks or ratios.....cant even change the DDR clock
either....
