Do note however that the developer of gominer has not released any prebuilt binaries and if you download that version you are trusting Riseman to provide a clean version.
Not saying he's necessarily untrustworthy but something to consider since this is crypto after all.
can i use this gominer mine with 0.5.2 beta gui, i mined for about 1 day nothing found.
Yes, but you must have at least 8.4 GH now to be able to find a block each day. You can also use the official miner since it's a little bit faster.
