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.
Update: After about 2.5 hours of hashing at increased rates last night, I shut down to plug in my amp meter and restarted the rig. When I restarted it, I noticed that I was only hashing at about 3.2 Mh/s per card instead of the 3.7 that I had just been seeing. So I restarted the miner from within itself and it hashed for about 10 minutes back at 3.7 Mh/s per card, and then the screen started flickering and sgminer shut down and I lost video.
Rig would re-set if I hit reset, miner would auto-start through my .bat file in startup and I would see 3.7Mh/s per card, but the flicker/black screen scenario would repeat itself after about 10 minutes and I would have to reset. I tried and went back to not using the custom .bin file, and reloaded my old config, but always the same scenario after about 10 minutes. Tried a bunch of things such as removing and reloading 14.4 and modded .inf files, same scenario. One time I got a message that I had unplugged an audio device, which was not true, but got me to thinking, so I deactivated the amd hdmi audio drivers after remembering that moving to win 8.1 caused me to reload amd 14.4 and I forgot to shut them off, but still no joy. Just did a system restore to right after loading 8.1, and I reloaded 14.4 + modded drivers, and it just crashed again after about 15 minutes.
I did discover that even with the 20% increase in hashrate, my power consumption only increased to 8.5A which is nice, but I might be heading towards a F & R since 8.1 is already pissing me off on its own for numerous reasons, but idk what the fuck I did to cause the miner (?) gpu driver (?) OS(?) instability.
