Overclock question

tareyza · January 23, 2016

So I have a R9 380 4GB graphics card and I've managed to OC it to 1141 core, 1598 memory with a successful Unigine Valley benchmark. However, when I'm playing Rainbow Six Siege, I occaisonally (like once per every few hours) get a crash at MUCH lower settings. I've gone down to 1049 core and 1452 memory and for some reason I still get occaisonal crashes, usually in the transition between loading screens or when the game is first starting up. I have core voltage set to various amounts, currently at +100mV and forced constant voltage with +20% power limit to try and ensure stability, however it still occasionally crashes. (The 1141/1598 OC was done at just +60mV) Any reason why it is still crashing in RSS occaisonally? Thanks!

Have you check the temperature? If it goes up too high, it will crash.

btw, just because "It works" with benchmark program, it doesn't mean that it's going to work well with game. Maybe you may need to reduce the clock even further. if you reduce the clock back to stock's clock, and it's still crash, then it's a faulty card.

and btw, I don't think R9 380 is a good overclocking card, because AMD already push the clock up from 918 to 970 (from R9 285 upgrade) which reduced the overclocking headroom (closer to Tonga's limit). It's depend on pcb manufacture as well, some PCB is not really designed for overclocking.
