Hi all, first post in Overclockers.net, etc.

Alright, so I got a Gigabyte 8600GT a good... 2 years ago, but only really got into overclocking recentlyish, and now I figured that since my graphics card is ancient enough to warrant significant fiddling without causing a financial catastrophe, I want to try voltmodding it (with a pencil, flashing the bios seems to be a nightmare without a floppy drive), since I get up to 61C under full load for about an hour, but if I push up the memory clock anymore it ****s itself and dies. It's currently at 660/1512/460 (I looked in the bios and it seemed to have low memory latencies, which would account for the low memory clock)
So I've looked around on some of the 8600gt voltmodding guides, but I couldn't find anything related to mine - it's a 512mb GDDR2, and doesn't seem to like the other 8600's it's been grouped with, and likes to be different. I've uploaded a pic


*shazam*

And I was wondering if anyone could tell me where to pencil/measure exactly? I've got a multimeter and that, I just don't know where to put it

I got my 8600gt up to 860/950...in my gpu sig link.
Once I save up money for a newer card, I'm gonna go for broke with this thing !

Here's where I got my info from:

I pencil-modded mine to 1.65V core and like 2.1V memory if I remember correctly. Got it all the way up to 920MHz core, 2024MHz shader, 940MHz (1880MHz actual) memory, but that was an EVGA GDDR3 card. I had to use aftermarket cooling, though. Got a Coolermaster Coolviva Pro SE that kept it nice and cool. The gains were very nice, like 5500-ish 3DMark06 using a 2.8GHz Athlon X2 Brisbane at stock clocks, and just a hair over 8000 with the above overclock and the same processor.
