Hi all, I could really do with some help here.
I have an Asus A68HM Plus motherboard with an AMD A8 CPU.
When I bought the motherboard I added a R7 360 Graphics card and to start off with Crossfire worked as it should. I then updated Radeon Settings and it disbaled Crossfire. I looked into this and found out that possibly my RAM was to blame so I checked the Qualified Vendor List and bought 2 sticks of 8Gb Corsair Vengeance Pro which should run on this motherboard at 2400Mhz.
However, with all the timing settings done right in BIOS, if I change to DOCP mode (there is no XMP) and change the voltage to 1.65, the system won't boot and I keep getting a Windows error screen. The timings I've tried are 10-12-12-31 at 1.65v.
I built the PC about a month ago (on a tight budget) and saved up for the newer RAM and I've been pulling my hair out trying to figure out why Crossfire is disabled when it was first enabled and why Windows won't boot when I attempt to run the RAM at it's correct speed.
If anyone could help me with this I would very much appreciate it. Thanks.
