The gpu however I took from 1.65 to 1.78. A handy improvement that got me from 460 to 475mhz. Still fine tuning it but either way I'm nearly 100mhz over stock.

It didnt make a massive improvement to 3dmark 2001 (16780) and I havent tried 2003 yet (takes forever)

Still it's not bad for a failed 9800pro.

Well, it depends on what numbers differ. What's most important is the chip model number. Many of the other numbers are for internal use, like batch and production numbers, revision, etc.

If you do not see a boost in memory voltage, try erasing the pencil marks and trying again. Don't put so much graphite in the first place and ensure the pencil marks extend to the pins.

weeehee, thx for the help did it yesterday went from 1.68v to 1.7v (i know not much to a diffrent but i didnt have more time) and i went from 470 to 480 so im aiming at 500+ with artic cooling vga silencer
edit:496 it locked up during nature test in 3dmark01 still no artifacts, 1.75v

Try 3DMark03 nature test too

ahh crap, ust detected the bad thing with this modd, i was going to increase the gpu voltage so i added some grafit and then i got lower v so wtf i thought and added more and more ust keeping going lower and lower so i removed it all and tryed again but with no luck, so later im going to do it the hard way, my birthday is in 8september and im going to buy a good soldering gun for the money

Hi

(sorry for digging up old threads)
I just found this article about voltage modifications on the 9800 Pro.

I would be interested in the other direction: undervolting the 9800 Pro.

@Max_87:
Would you have an idea for a similar wiring to enable undervolting only?

Max_87 · 31st Dec 2005, 09:24 PM

LoL! I have no idea

Why would you want to do so anyway?

Card gets too hot inside a compact barebone.

Hmm.. Why not add a case fan to exhaust the hot air?
