Interesting fact: after modification timings Gigabyte HD7950 gives stable ~330H/s with 1% rejected. (1190/1470) - Pic 1

If increase mem frequency up to 1500, GPU gives ~361 H/s. But about 15% of rejected. In log file appears strings of buffer overflow. - Pic 2

What does this buffer overflow mean ? Obviously, hashrate indexes is not very accurate ?

No it doesn't. There is no way that a 7950 gives you that higher hash rate than a 280x AND a 7970..

Yes its possible with that crazy high engine core clock rate.

I seriously doubt it. Clock rate isn't going to magically disregard the narrow memory bandwidth, and make it run 100 h/s over a 7970.

What is a typical h/s rate for a single 7950 card?

240-250 h/s
