No forgiveness needed, l got off very lightly with that one!Don't think the motherboard supports xfire so wouldn't worry about that just make sure you check in the bios the pcie slot is running at pcie4 or pcie5 so your GPU is running full speed.
You have a right to be paranoid with the problems you had but I did laugh about the pc going into sleep mode. ( Please forgive me )
When you get a chance post a pic of the infamous pc.
Just realised l havent checked the bios setting for the pcie mode but its been a busy few days, l did take a couple of snapshots of hwinfo after playing jedi something or other - not my type of game tbh but it was free and seemed to tax the system much more than dcs which is what l was after. If l read the info correctly the cpu boosted to 5.5 across all cores but at 1.465v.....gulp. The latest bios that isnt beta doesnt include the 1.3v soc limitation....
For the GPU is it the 'front end clock' that shows the GPU speed? Thanks.
Ive attached the pics and a couple of the system, the rgb is just white as its in the sitting room lol. Not sure about the cable management for the GPU power supply hehe.
