Overclocking
When it came time to overclock the Asus Matrix R9 280X Platinum I really couldn’t wait. Everything about the card design is focused on its overclockability from its increased power plan, the TweakIt controls, and Asus’s GPU Tweak. The card started with a nice overclock right from the start both on its GPU and Memory so I knew I had my work cut out for me from the start. I started with a big jump from 1100 to 1200MHz on the GPU with good luck. My next pass was at 1300Mhz and as soon as I loaded my 3DMark 11 benchmark it hard crashed requiring a reboot. The same happened when I ran at 1250MHz. I settled on an overclock of 1225MHz but I will admit that I think there is a lot more left in the card if you get into voltage adjustments on the card. On the memory side of things, the reference speed was 6000MHz and the Platinum edition came with an overclock to 6400MHz already. I jumped right up to 7000MHz and passed without any issues. Next I attempted 7500MHz with worse luck. From there I worked my way up only to find out that a hefty overclock of 7400MHz was still possible without any voltage. Just to be sure of my results, I put them together and ran through a combined test as well without any problems at all.
