Hi all,
I am new to mining. Just started few weeks ago. I started off with experimenting with different voltage, gpu core speed, and memory speed and I managed to get 24-25 Mh/s. I went a step further and modded the bios by adjusting the memory timing and I think I started to see 28-29+ Mh/s. But when I reviewed the log files and plotted out the average Mh/s, it around 26.5 to 27.5 Mh/s.
I loaded them into an excel spreadsheet, grep the speed and counted the average. So I think that is pretty accurate.
Anyway, I like to share what I am seeing on my mining stats. I hope the community of miner can give me some enlightenment.

Sudden drops to as low as 20-23 MH/s. Inconsistent hash rates. I suspect something is wrong and I am out of idea on how to fix it.
My best stable watt/hash rate setting is 1150/2150 @ 900 mV and that yielded average 27 MH/s.
I thought the GPU was throttling due to insufficient power, so I raise core voltage 1.15V to eliminate the power factor but it didn't work. Is what I am getting a norm? It is driving me crazy. I am planning to buy more GPU but I don't want to commit until I resolve it. Can someone help?
