The card is on enroute to me, made by STB, AGP card.
I have soldering skills so SMD repair, electronic test tools is not a issue. Due to my job, I have to deal with this daily repairing cell phones and tablets means I use hot air station and soldering irons.
I plan on replacing the dram IC as I have source to get new 6ns ICs but I could not find any 5ns SDRAM 1mbit x 16 bit 3.3V ICs 50 pin TSOP.
Received the video card and went to repair that thing, hopefully the big bucks not wasted on it.
Artifacting was scratched tracks in memory bus area.
Blank jailbars was bad memory chip somewhere, I replaced them with new micron 6ns sdram from USA selller on Ebay, instead of samsung, replaced three electrolytics with MLCC capacitors and the smashed tantalum for MLCC capacitors. All the MLCC capacitors were salvaged from junk video cards.
