Hello,

I just restarted some miners after long time.
I am using 5.5c on 580 8Gb since later versions gave me errors. They are all around 29/31 Mh, can I squeeze some more hashes ?

Also one 580 is a 4Gb, so I am mining ETC, but the Mhs is around 15 Mhs, I remember it suppose to be around 29.
There are the settings I am using:
-proto 2 -coin etc -cdm 0 -stales 0 -worker AMD5804G -gpus 1 -amd -acm -astats 1 -astats 1 -leaveoc -mi 14 -gt 40 -gser 2 -wdog 1 -tt 80 -tmax 80 -fanmin 70 -fanmax 85 -powlim -15 -cclock 1200 -mclock 2050 -cvddc 930 -mvddc 960 -log 0

Also -tmax 80 not working, it sets it to 84 default.

Am I missing something from when I was mining with version 3.0 ?

thx

Here are some tips from me:

-powlim -15 I would drop this. It does not work well with AMD cards Especially when using -cvddc and -mvddc
-cclock 1200 I would lower this in the range of 1100-1150. Change slowly down until hashrate starts to drop and go 1 step up.
-cvddc 930 I would lower this in the range of 850-900. Also, change slowly.
-mclock 2050 This should be fine to go up to 2150, but it depends on the memory brand and on the GPU brand.
-tt 80 -tmax 80 -tt number must be smaller than the -tmax. With setting lower core clock and lower voltages power use and temp should drop too. So you may set -tt 70 or 75.

Also using these commands should improve hashrates:

Code:

-mt <n>
VRAM timings (AMD under Windows only): 0 - default VBIOS values; 1
- faster timings; 2 - fastest timings. The default is 0. This is useful for mining with AMD cards without modding the VBIOS.
-vmr <n>
Memory refresh rate (0 to 100, default 0). For AMD cards you may
also use "-rxboost"
-rxboost <n>
Memory refresh rate on AMD cards (0 - default value, 1 - predefined
value that should work on most cards, 2 to 100 - increasingly
aggressive settings). If you want to fine tune the value, you may
run the miner with "-rxboost 1", write down the corresponding
"-vmr" values that are showed in the log file, and then use "-vmr"
instead with adjusted values.
