Re: ASUS V8420S Ti4200 Diagnostic help needed

Posted on 2019-10-23, 12:59

OK, not completely sure how to carry this out and insuring I am measuring on the right termination spot. Would it be easier to find a spot (if any) on the backside of the card that is connected to that trace also? You just have to poke through an insulating coating of the trace (solder mask) using …

On closer inspection, I noticed a scratch on the stock one, near the AGP interface, I checked for continuity and if there was a short. I could not detect one, but I can't measure where the connection terminates. Or rather I don't know where or how to measure if there is a solid connection. Press in …

one of the cards has a tiny square in the upper left corner that is corrupted It doesn't look like a typical, TMU memory related, texture corruption. What happens with the square when you set active only 1 TMU or disable texturing using environment variables? Post actual screenshots of the games. …

There was no exceptional temp. difference among good and bad DRAMs, unfortunately. DRAMs closer to the FBI and TMU were always hotter. Second bad DRAM was on bank0 (on TMU side) and it was semi good, which made it way harder to pinpoint, so after some testing and reasoning I've concluded that it …

Replaced the crossed out DRAM IC, but texturing errors still remain. There is at least one more bad DRAM somewhere around the affected TMU :dead: Original picture: bad dram.jpg DRAM IC is removed: no dram.jpg DRAM IC is replaced, ground textures are as it should be now: dram replaced.jpg After …

After almost 1.5 month due, the DRAM ICs finally arrived. Every chip came from a different batch, because none of the date code on them match, but parts are legit and working. Filename 1.jpg File size 820.92 KiB Views 983 views Filename 2.png File size 437.58 KiB Views 983 views

I'm fresh out of working Voodoo cards I'd try to make at least one functional voodoo from few non working units first, but before that I'd go with one of these: Riva 128 - period correct, but ugly looking DX6 3D games; Riva TNT - godsent compared with a R128 in terms of performance, period correct …

ASUS K7M is pretty solid but it has AGP compatibility issues like most other non Intel boards of the time. Voodoo3-5 or NV TNT2 are good choices. Those were stable at AGP 2x on my K7M. Geforces and Radeons will likely run at 1x and if I remember right are still not entirely stable. ^This. If you …
