Drivers & Software

[scotchbrandtape]

I just bought a RX 6600 for an older system that I'm trying to squeeze a few more years of 1080p gaming out of. It all ran just fine with my (hopefully retired) HD7850, but with the RX 6600 installed I'm experiencing very significant visual glitches and bugs. They happen on the desktop without putting the GPU under any load at all. Running a stress test doesn't seem to effect anything (the glitches are the same, not better or worse).

System

Card: MSI RX 6600 MECH 2x 8G

Processor: i5-3570k

Motherboard: P8Z77-V LK

RAM: 16 gb DDR3, 1600 MHz (2x in 4gb DIMM, 1x in 8gb DIMM)

OS: Windows 10 Pro 64 bit

PSU: Cooler Master 720w

2 monitors, DVI and HDMI

The visual glitches don't happen when I'm running the card on stock windows drivers, they only start when I install AMD Adrenaline & drivers.

It's been basically a full day of troubleshooting, so I've already tried the following:

• Updated to most recent Motherboard BIOS
• Updated to most recent integrated graphics drivers (required physically removing the card)
• DDU clean wipe of drivers and fresh install (several)
• Reconfiguration of RAM DIMMs
• Complete windows clean install
• Changed out monitor cables and configurations

Because the artifacts only start happening when I install the AMD drivers, I'm convinced that it's a software issue. However, my motherboard does have some 'smart' overclocking features that I've never paid much attention to (with the HD7850 I was always GPU bottle-necked). I've tried to turn them off, but I'm not positive I've done everything correctly.

Any ideas?

Are you running any overclocks? Best thing would be to try and set the system to default and test again. Those glitches can be graphics memory corruption (output buffer issues), or an issue between main memory and the GPU. 

Assuming these problems are always present, have  you tried to install older version of the drivers at all? 

I noticed a strange configuration of your ram. Could be fine, but its worth a try. Normally you should only populate 2 slots or 4, not 3. Try removing one DIMM. Id simply remove the 2x 4 gb for now and see what happens.

Im having issues too with my setup, so i figured id post a thought or two on your thread. Good luck.

Thank you for the reply!

I completely agree the RAM configuration is odd. I've now tested it with a single DIMM, as well as the two 4gb DIMMS. I also installed a version of the drivers from January 2022. 

Unfortunately we're still having the issue. Is it possible there's a hardware issue with the card? I've just assumed that the drivers are the problem because it works with the standard windows drivers.
