A1 and B1 revisions - 7600GS, may be old...but

...but if i can get 50% overclock on stock voltage and fan (which i have!) with no case fans (hoping to drill a 250mil slot in the side panel to get a 105cfm silent fan ), that would be worth it! i found a guide here: http://xtreview.com/review114.htm after a google search, and it gives a diagram that shows where to do the pencil mod...
my question is: could the resistor possibly be in a different place on my B1 (its an A1 in that review), or is that a purely gpu architecture/clocks revision (my palit 7600GS Sonic {which incidentally came in a normal 7600GS box, i had to look at the little sticker on the card!} has its mem at 50MHz higher at stock (hehe, and didn't it go further with the help of atitool )

sorry for the probably garbled thread, lol

thanks look forward to your responses.

EDIT: could the revision be agp/pci e? i don't think so but you never know... mine's an AGP, and you would think B1 would be the newer revision, so therefore B1 should be the pci e... meh idk!
