sgminer-4-1-0-windows

Sgminer 4.1.0 is another Scrypt GPU miner that is based off the latest cgminer version 3.7.2 that had support for Scrypt GPU mining as all of the later versions of the cgminer support only ASIC mining hardware for SHA-256 and Bitcoin. Sgminer 4.1.0 is very similar to cgminer 3.7.2, though there are some interface changes and also there are some extra features such as multiple experimental kernels to play with as well as some of the features found in the cgminer 3.7.3 kalroth edition such as xintensity and rawintensity modes besides the standard intensity mode form cgminer. If you are interested in trying out something different you might want to play with sgminer as it has some other useful features that are not available in the standard cgminer, the download link for the windows version is available below.

I get the same error with sgminer 4.1 as 3.7.2 & 3.7.3-kalroth, any ideas? Windows 7 Home Premium, new Radeon HD 5450 card:

Have you checked your video drivers, try reinstalling them if you are using the latest version.
Also check the settings in the config file, there is a mention of the lookup-gap in the error you are getting.
You can also try to lower thread-concurrency to 2096, and gpu-threads to 1, also smaller worksize to 128 for example. Have in mind that even if yo do manage to make the card work, the performance you will get will from this model will be very low.

Tried running this (jumped from cgminer 2.11.4) and seemed to get comparable hash rates and WU, but I killed it once I noticed f’n HW errors, which I’ve never seen with these settings in cgminer 2.11.4. I did use the exact same conf file from cgminer (didn’t change or use any of the additional settings in the sgminer conf yet), but admittedly that has scared me off sgminer for the time being until I feel in the mood for some from-scratch settings discovery…

sgminer is based on cgminer 3.7.2, so there are quite a few differences than what your old version may use in the config and that could be a reason for the miner to not function properly. Also note that sgminer tries to push the GPU to the maximum, so cards that are overclocked to their limit and working with cgminer may show problems when switching to sgminer.

If I were to start backing off the aggressiveness of some of my config, is there any possibility for improvement? If not I don’t see a point in upgrading now.

Not the aggressiveness, but you might want to check your clocks and try with them lowered a bit. Also try with a new config just adding your pool and worker data, not moving all of the using the settings from the old cgminer.

Oops, I meant aggressiveness in a generic way (not intensity). Oddly enough, I tried running it again and have been running for about a day with no HW errors. Dunno what happened before, maybe some bad clock setting which changed after a crash & was fixed…

I think what might be causing the hardware errors (seen a few more) are restarts of sgminer after I’ve underclocked a few cards, or when I underclock cards while it’s running. I guess the next step seems to be finding the parameters needed to have sgminer handle that instead of Afterburner (hopefully it can).
