Same as mine that goes up to 2300...but to go that high, cooling should be made
in such way that metal plate covers not only GPU, but memory, too (and replacing
usually bad factory thermal paste with quality one)
However, 2100 should be easy to achieve
Also, important is to find sweet spot between voltage and temperature (voltage increase
improves stability, but only up to the point where increased heat starts to be a problem)
I bought it from a miner, so it came with some thermalpads and a good biosmod, but not all ICs are cooled (only 5/8) because the other three arent in the cooler contact area. I ordered some heatsinks at Aliexpress but it will take a little time to arrive (3 months. Yeah, Brazil's mail is poor).
About the memory strap: The board came to me with Matthev timing. I tried many timings (heavyarms, yours, some for anorak's) and the original one (matthev) was best (at least at 1900~2000 clocks). I did some changes/tests and for now I have it:
777000000000000022CC1C00CE615C41C0571016B30CD50900400700140514207A8900A00300000

Is there a way to improve "performance per clock" for Cryptonight? (considering that it couldn't run at 2000+)
Some don't clock as high as others do. I have couple of cards that don't go above 1950 without causing lots of memory errors and eventually crashing.
The core on these cards need higher voltage and the cooler isn't good on these cards either which makes it even worse for stability. Both cards are from same batch so it might be just that.
