I'm getting steady 30MH/s on each Fury X on stock clocks (1050/500). Claymore's can only get about 28MH.
A 390 at 1040Mhz gets 29Mh, with some overclocking I can surely can 32-33MH, but my cards warm up too much. Definitely the best miner out there.

The only issue I can spot is the CPU usage, which makes this miner basically worthless on weak CPUs. I couldn't run it on a single-core AMD CPU and a friend of mine had his rig crashing with a dual core Celeron installed. most mining rigs have very weak CPUs, and if this miner gets updated to support them, I am sure it will get much more traction.

Has it been determined that this issues running on systems with weak CPUs is real? Is there a fix coming? I am wondering if this is the problem I am having on my multi-gpu mining rigs. One GPU run at the right hash rate while the others run at half. No matter what I do with the settings I cannot resolve this issue. Both rigs have single core AMD CPUs. I would love to use sgminer with its RPC capabilities but I am not going to invest in bigger CPUs for it.

Thanks.

If you search Wolf0's post in this thread, you will find that he posted a fix for the CPU usage bug.

Here it is again for those that don't want to look back through the thread. I can confirm it no longer hogs the CPU on one core.

copy sgminer.exe from the zip to the existing install directory.

Thanks. I will give it a try.

UPDATE:

I tried this version and I get the same result. I have no idea what is causing this problem but I would love to hear any suggestions.

Thanks.

Update II:

I resolved the issue. It turns out rather than increasing the fan speed from the lowest speed in the fan range, the miner was decreasing the GPU speed when the temp reached the target temperature but only on 2 GPUs for some reason. I resolved the issue by turning off auto-fan and setting the fan speed high enough to ensure the GPUs stay under the target temp. When I get a chance to shut it down I will try to specify fan ranges explicitly for each GPU.

I removed the auto fan and use the MSI afterburner to many the fan speed, it is much better.
