Here's what happened, I run heaven benchmark before the bios update 5115 for asus Prime x370 with 1700 r7 CPU, 16gb ram, my Graphics card is a RX 480 8gb ram 1288mhz. The update went smoothly no apparent problems at first then I run Heaven Benchmark again but this time it ran somewhat slower and instead of saying I have 8gb of video ram it said I only had 4gb. So I put the card in my other computer to check it out and it run just like it should with 8gb ram. Could the bios update have done this or did I foul up something? Is anyone else have this problem and if so do you know how to fix it? I'm still working on it but I'm running out of ideals on what the problem could be.
