well... here are the tips which is my guessing at best to GF4 with 8RDA+ (read the sticky in the epox mobo)
Your VisionTek GF4 Ti4600 is on the list. Two people fried it both version A and version B. Now VisionTek has gone under although the company brought visiontek said they will honor the warranty, however, they have few cards in stock. So if you want to RMA you need to wait for a long time.
I do not know 8RDA+ rev 1.1 will solve GF4 crisis for sure. I don't work for Epox although I like it very much. My 8RDA+ serves me great.
Standard Procedure installing your GF4.
1) Use a wrist band. ground yourself. touch the psu.
2) Install your RAM first before you install your GF4 (install the card last so prevent you from bending your gf4 when install RAM)
3) If you have a none GF4 card, boot the machine first and flash it with the latest official release bios.
4) Turn off the machine and install your GF4 and make sure you do not bend the card or rub off any small tiny capacitor (sp?).
5) If you need to swap your RAM or move it to a different slot, take out your GF4 card first.
