Just wanted to share some info on my overclock of my new R9 390 from Gigabyte. As most of you know, the Gigabyte R9 390's have locked voltages but I was pretty happy with the overclock regardless of it having a locked voltage. I bought this card already knowing of the locked voltages and opted for the G1 series of their R9 390's. Anyways, I wanted to post this before i go, I won't be around to reply back as i am going out of town but for anyone interested in what a Gigabyte R9 390 G1 Edition can do even with locked voltages here you go, although some of it has to do with a per card basis, its not guaranteed every card. Also Keep in mind, i could of went further but opted to stay here and not push it any further. In fact i only did this to see what the card could do, as right now i have no desire or reason to keep it overclocked, maybe down the road i might OC it to get a bit more performance out of it but for now..no reason other than to see what i could do. So i basically went as far as 1125mhz core/1625mhz memory with simply raising the Power Limit 10%, that's all. I left this run on GPU-Z's overclock testing for 30 minutes and played Battlefield 4, Crysis 3 and COD BOPs3 for a few hours non-stop switching between games during these few hours while keeping the card running with the OC. It's nice and stable and obviously could do a bit more but this is about as far as i feel i would want to go in the future.
