First post in this forum, just to say good job Claymore on the 10.0 version, it seems to take really well the clock and voltage options now if paired with AMD GPUs and the blockchain driver.

I would like to ask Claymore 2 questions:

- I have probably have run into a little issue in regards to core voltage settings with the miner. I have one GPU that when set to non-rounded voltage values (as the GPU only recognizes 6.25mv steps, this means all the voltage values that arent x25mv, x50mv, x75mv and x00mv) it misheaves pretty quickly and has OCL thread hang just a minute after starting mining (DAG is already loaded and no EDC errors are shown. If I use rounded values, it seems to take them better and if a OCL thread hang happens, it happens after several hours and probably blamed to memory clock instability.

- As you know, the clock and voltage control API from AMD has a mechanism built in that in the end reduces performance very time you touch any core/mem voltage/clock values if they were changed AFTER the GPU entered, even if for just a little moment, in maximum core and memory Pstate. I have seen when doing the OC/UV settings with your miner that the settings I put are enforced just before the DAG loads, but still with soft monitoring the GPUs enter for a brief period in max clock/voltages before that, causing that any clock/volt setting enforced by the miner, if it happens to change an existing value (this doesnt happen at all if the GPU had these values since last reboot), it enters in this "reduced performance mode" and thus hashrate is lower than you should. Is there any chance that the voltage/clock options are enforced first of all, so this behaviour doesnt happen? Because every time I have a OCL thead/hang, I have to do 2 reboots, the first one automatic from the miner and the second one to have the clock/volt dialed in a first time so the next reboot the GPUs dont enter in this "lower performance mode". i know i could just bios flash all the OC/UV/fan settings, but im still at finding the best OC/UV settings for each gpu, and I would like to nail them via driver changes rather than BIOS modding yet.

All in all very satisfied with this new version.

Thanks in advance!

I'm running v10 and the overclocking and voltage control are pretty great features, but they need some more work.
I have a very strange problem. Most of the time, when I power on the rig and start Claymore, the cards appear to be clocked to the correct frequencies set in the .bat file, but they mine with the hashrate of stock clocks. I have to stop Claymore and start it again for the cards to mine properly. For example, at stock speeds (1265/1750mhz) they mine with 24mh and at 1100/2050 they mine with 29mh. On the first run, gpu-z shows 1100/2050 clocks but the cards mine at 24mh. When I restart Claymore, the cards are at 1100/2050 again but they mine with 29mh. Also, sometimes the voltages don't change accordingly, so every time I have to check the voltages with gpu-z, to see if everything is correct and this kinda blows the idea of having a fast way to restart a miner and have him up and running in no time. I know other people that have the same problems. Hope that this gets fixed soon, since this automatic overclocking from Claymore is an extremely helpful and easy way to overclock.
