As I have basic knowledge on GPU OC I need some advice for my Gigabyte 970 G1 Rev 1.1. Drivers: 344.75 ASIC: 81.5% Just as a side-note I have PCI-E 2.0 (due to SB) if it matters +115 Core +300 memory 1. I see everyone reaching 500Mhz easily on memory. I get artifacts on both Furmark 18.104.22.168 & 3D Mark (Firestrike) whenever I go past 300MHz. I guess that's the max I can reach? Does voltage helps memory by any chance? 2. Another thing I don't understand is that while I have Boost clock@1444 it goes up to 1519MHz on Furmark. Am I missing something? 3. Also, I noticed in NBA 2k15 that the core clock jumps up and down (from 1200 to 1570). Is this normal when I have set it on 1293MHz and boost@1444? Thnx in advance for the feedback!
