Re: Genoil's ZEC miner: AMD ZCash miner for Windows

Im using my 7950 shappire rig of 6 gpus getting a media of 16 hashes per gpu. is this good for this type of gpu??
Is there any ways of use 99% of my gpu usage, im stuck at around 85%?

Thanks for the help if u could. Grin

If the GPU is sat between 80~85% as your graph shows it suggests that they're memory bandwidth/latency limited. Most 7950/7970 will happily do atleast 1500MHz, start there. Failing that you probably want to use a custom BIOS with tighter timings, usually copying a memory strap from 1250/1375 to 1500 does the trick. When I used to have 7950s I was using tighter timings(The Stilt's) and memory clock was around 1700MHz. This provided excellent performance for scrypt and Eth type crypto.

Kind of slow mine does 20-25 sol/s with genoils miner 0.4.2 on stock settings

Now im moving on average 19.5 but reach 25 seems too much. I can only increase the memory clock from 1250 to 1575.

Btw thanks walrus. One more question u guys think genoil is the better miner right now? I have issues with all the miners but i dont know if there's a better option out there. Claymore is going to release his own zcash miner hope it works great.

You may find the best trade off of performance and stability is found with the memory clocked to 1500mhz exactly, not one mhz higher. This is because on stock cards, at 1501mhz+ you trigger a different memory strap and therefore it can be slower. For my modified cards I copied the strap for 1500mhz to all the higher straps, that way I never lost any performance going higher than 1500mhz.

IMO, currently Genoil's miner is hands down the best.
