Hmm, glad that it worked for you guys. I tried that both with lasys and the "14.6fixed" miners, didn't see an increase on my 7950s though.
I think that it might be a problem with win8.1 and the 14.4 drivers because I noticed that I actually lost about . 1Mh per card after "upgrading" from win8 to 8.1 and running 14.4 modded driver (I have six cards) and lazys miner like I had been.
I'm running Windows 7 with the 14.4 v3 mod drivers, lasybear's miner (sgminer_x11x13mod_03_06_2014.zip), and Pencha's BIN file.
I have 6 GPUs per machine and get 3.7 m/hash per card @ 1080/1500.
How much are you getting currently?
I'm seeing about 2.89 Mh/s per 7950 card (sapphire hd7950 non-reference) running win8.1, 14.4 modded driver, and lasy x11 miner. (Was seeing ~2.99 with win8 before I "upgraded".) I put the .bin file in my miner folder and didn't really change anything though, so I tried a different miner with the new .bin and still saw about 2.89per card. I wonder if the lasy x11/x13 build is better than the x11 one. I might have to run it to see, but I'm thinking that either one handles x11 the same.
What's your WSize and TC set at? Per the name of the bin, you need to be set at 256 and 8192 respectively for it to work with that bin.
Interesting, I will give that a shot. Worksize was set at 256 but TC was 23,xxx , and then I deleted TC because I didn't think that it was necessary with these x11 miners. I'll try out what you are saying a little later though.
If you delete the bin, the kernel will just generate a new bin file from your own setup... it'll be named something like x11modTahitiglg2tc23000w256l4.bin based on the settings you just gave, but it won't be optimized like the dropbox linked one is. The numbers in the name correspond to matched settings with your current config.
Try again with TC of 8192 and the dropbox provided bin file.
Ok, changing the TC in my config to match that of which that was specified in the .bin seemed to help out a lot.
I would not have known to do that about matching the TC numbers, thanks man.
Now I'm seeing around ~3.7 Mh/s per card. I just kicked it off, so the hashrate may taper off a little. No HW errors, and we'll see what the WU settles at in a few hours.
Win 8.1, six Sapphire hd7950 non-reference, amd 14.4 modded drivers, lasybear x11 miner, Penchas .bin.
My mem and engine clocks are running where I set them to in my config.
The cards are running a couple of degrees hotter, but still cool and much cooler than mining scrypt & N.
I'll plug in my amp meter to see the rigs total draw a little later. It was ~ 8 amps before.
I may have to test out a couple other miners, I think there is one that is supposed to kick out some more hashrate.
Here is my config that I am currently using, for better or for worse. I spent some time dialing in the clocks.
