AMD 6800XT Owners - Share your experiences!

Recommended Posts

I am on Intel 10-series and z490 chipset with this card, the MSI Trio version. 

Was plagued with black screen/green screen and hard-freeze issues when it first installed - BUT - seems there are still some underlying issues around DP and monitors with either drivers or the card. 




3 monitors

1  24" HD IPS, 24" 1 HD LED, 1 27" HD 144/165 Gaming 


The old 24" monitors are 60hz and only have DVI/HDMI no DP connections - so using DVI to HDMI cables - work flawlessly.

The newer MSI Gaming monitor is the G27C4 variant and offers 165hz @ DP or 144 @ HDMI.  


When I use a DP cable for 165hz on the gaming monitor it's super weird.  Windows doesn't remember positions when waking from monitor sleep and the identification of monitors does not match between Windows and Radeon drivers.  Refer to monitor setup below.  When using monitor #3 with DP, windows sets that as #1 - and numbers 1 and 2 become #2 and #3 respectively via Windows, where as Radeon does not identify the same monitors as the same.  If I use all-HDMI connections, Windows and Radeon drivers identify matching monitors.  I have tested with clean driver installs, with old driver sets (back to Nov release drivers for 6000 series only) and via Radeon updates.  Seems driver/DP related but dunno why.  I've read that the DP ports on this card are 1.4 release whereas the monitor I have is 1.2a and this could be an issue somehow.  I have only tried cables that are 1.2 and unknown versions purchased at local computer recycling center.  Ordered a 1.4 cable and is on the way, so will test when it arrives but I don't think it's cable related anyhow.


(Windows via all-HDMI setup)




Please share anything you've come across!  AMD or Intel platform.  Is anyone with AMD seeing better results due to native SAM implementation?  Anyone know how Re-BAR is supposed to work on Intel z490/590 chipsets with BIOS updates?


Aha. Disregard my smoke filled brain.  Enabled in BIOS right in PCIe section, cause, you know, READ dummy (note to self).
