One of my miners is a similar hash - hasn't found anything in ~48 hours either but it doesn't mean it's broken! It's hard to get accurate sampling in statistics from one node, I haven't found a pattern or even 'best machine' from my miners - the most blocks I have found are on my lowest hashrate! These things need time and stability to even out even mining for a few weeks isn't long enough IMO to settle into the rhythm




Or to find out market value to help with calculating mining cost/profit
