I won't claim to be fully stable as I haven't done long stress testing yet but it's able to pass shorter runs of TM5 at least. It surprisingly did not take that much voltage for 6400c30 but I can't stabilize c28 even at 1.55V. It does boot but it errors in TM5 within a minute or two no matter how much I bump up the voltage. I can boot 2200 and even 2233 FCLK but I saw some inconsistent performance in benchmarks so I went back to 2133. Latency isn't as low as I'd like but I am running on lvl 2 core tuning since it seemed to be a bit better in Superposition benchmarks which I assume translates better to actual game performance than AIDA64. Also have virtualization turned on as I do plan on using some virtual machines. Can only run GDM off on 6200. Any suggestions on further tuning?
