Title: Voodoo Rush mod from 6Mb to 8Mb - bigger is better
Post by Komponent on 14.04.13 at 16:44:09

Starting with one Yakumo Voodoo Rush, 6Mb of 4Mb FBI + 2Mb TMU, I got 926 points in 3DMark99Max.

Soldered piggyback style 4 chips of 512Kb for the TMU except for RAS pin, identified the command pin on the TMU chip (reverse engeneering as there is no databook available) and connected them with wire and resistor.
The card works perfectly using the extra RAM, with more than 100 extra 3DMark points.

Shame you didn't do a before / after texture quality comparison for games... :P

I'd bet it would be sharper now! ;)

nice

can you also build a 8MB TMU Memory 2themax/ Gainward/ Cardexpert rush?

nice indeed. would it be possible to do something similar with a v2, I wonder? maybe 4MB for the fbi and 8MB for each tmu?

FBI's on Voodoo2's already have 4MiB. Would be nice if they had 8MiB.

@all: Thanks for the props ;)
@paulpsomiadis: I did not pay much attention, but I did not notice any clear difference in quality.
@exxe: Can't say for sure, but I do have something different in mind; maybe someday I'll try it.
@ps47: Something similar for V2, I doubt. Though I plan to test another angle in due time, when I'll have some funds.

DIY guide:
Stack RAM chips ontop those 4 allocated to the TMU and solder each pin to the same below except pin 14. Connect pin 14 on all 4 piggybacked modules to pin 130 of the TMU through a 22-47 ohm resistor. I only had at hand 100 ohm ones and used those and had no problem.
