Low Hash Rate After Gaming

[JackBits]

When I go back to the desktop after gaming and start cgminer, I get really low hash rates in the single digits (usually get well over 350k for scrypt). If I reboot, all returns to normal. Of course its a pain to have to reboot to switch from gaming to mining, so I'd rather not have to do this. Seems like the video card is not being restored after the games are shut down. I tried the GPU restart in cgminer, but it didn't help. Anyone know what might be causing the issue or have this happen?

Here are system details:
Games this happens with: Stalker Pripyat, Call of Juarez, Battlefield 3, maybe others
Video Card: XFX 7850 Double D 1GB
Drivers:13.1 Catalyst
Windows 7 Ultimate, DX 11
CPU: E8400 @ 3GHz
RAM: 3GB (Max MB will run reliably)
MB: Gigabyte P35-DS3L
cgminer 2.11.4

You're lucky--I have to switch ati drivers when I go from mining to gaming (medal of honor won't run with the latest drivers, and cgminer won't run without them).

It's the same issue as I have here. The miner ends up being loaded in "dynamic memory" and mines really slowly. You can see this in GPU-Z. Haven't found a fix yet.

Thanks for the replies. Seems like its an issue then between cgminer and windows/drivers.

hi, i have the same problem with a Sapphire hd 7850, i mine Litecoin at 360-370 kh/s but if i close cgminer and restart it, i get 20-30 kh/s
i also have to reboot to recover normal hashrate.

is there a fix or something to do to solve this problem? thanks

I understand you... I have exactly the same problem and the only thing I can do is to restart system...

Hey guys, I have three years of mining experience and I can't stress enough that mining is always significantly easier in linux, whether it's CPU, GPU, FPGA, or ASIC!

Try to start with lower intensity after gaming. works for me

i have found that playing a video or running the copperlark miner for a minute, and then start cgminer again will fix the hashrate for me quickly.  just try running something simple that will make use of your card and it should go back to normal.  not very tech but it works for me

13.1  is not a good driver always have a problem when using this version.

Try to close all your browsers and Skype after your gaming session, happened to me twice, the first time I had to reboot but the second time, I tried something: closing Chrome and Skype helped.

What is your bat file looking like?

If you are using powertune and go from gaming to mining or from mining even back to mining it can get messed up and reduce hash rate by a hundred or more Kh/s.

- tip to play video doesn't work 
- dont have chrome or skype installed 
- dont use bat.file, i use .conf file, tried command line >>same 

In fact after restart of cgminer, gpu and mem are at stock 2d values , it is like cgminer can not read or load the config file

Thanks 

But... one question... may I set that process into a bat file?

Yes... but correct me if I'm wrong.. this is for a running program and what I want is to disable the graphic card and after enable again and put both actions in one batch file... may I do this with taskkill command?

Nah, I misunderstood.  If the solution was to kill the process in task manager then you can use the command line I posted.  Else you can use a tool that will save the command line args, like this one:
