For a good week+ I was able to get 620 kh per 7950 and nothing less then 250 kh on the 7850.
Well, as a stupid rookie, I played around with some script settings , seeing what I could do with it and at the same time, learn about it hands on. After enough fumbling my original script isn't as optimal anymore (at least I can only assume it is my original script.. Anyway. that 620/250 average as gone down to 560/230 average. Maybe having 1 card hitting a low 600 for a few seconds at a time, and then right back down into the mid 500's. I didn't change any pools, and it did this before and after the recently difficulty change.
Bottom line, If anyone could help me with a script to maybe get back to my originality hash rates, I'd be forever greatfull. Especially because I know this rig is capable of this, as Ive seen it first hand.
I am a newbie, as If that hasn't been clear thus far
I have above average computer knowledge overall, but mining is very new to me, specifically, scripting.
To make the specs of the rigs as detailed as possible, I included a DxDiag file. (both rigs suffer from this, and both have identical hardware)
Anyone who can help, or even attempt to give me advice. I greatly appreciate it!
I know specifics play a big part in scripts. I didn't want to flood the thread with too much of the DxDiag file, as its very long. I used my noob knowledge to pick and choose what I thought would be the key features.
I have 3 x Sapphire 7950 and 1 x Sapphire 7850 per rig, and an amazing 1300 watt power supply.
Sorry for the lack of info. It's very late and I was debating posting in detail in the morning, or give it a shot with the info I've got before I crash. Figured it could maybe generate a reply or two, either way I'll grab the boxes of all my gear and get specific information on each hardware piece. Down to the model number if need be.
EDIT: It appears upon confirmation from the gentleman who created me the script, that the version I had was in fact the correct version. He's doing some checking now to be 100% sure that's true, but if by chance it isn't the script, what else could it be? Not sure if this is a factor, but I keep my rigs very well temp controlled. 60 - 61 at best on a GPU here and Mid - High 50's is a general average.

<--- Yes, I know the date isn't current. one of my rigs is, one isn't. Both are suffering the same issue, so I figured that wouldn't matter
