BitCoin Mining problems (GPU connection/cummunication problems)

[WobbleBoop]

I am posting this here since I am a newbie and therefore unable to post this in the hardware section.
My GPUs are working at a normal rate though I randomly see them having connection problems and they're not generating any BitCoins...
(This is in Slush's Pool and the GPUs are two AMD HD Radeon 6770s)

and here's the console: http://gyazo.com/c63f64663f7477c5252b3aa0994f7597

I have found that downgrading the Graphics driver (I am on 13.11v9.1) and deinstalling the newer OpenGL versions fixed problems similar to this for other people, though I like to play games (such as BF4) on this desktop too and downgrading to ~11.11 would influence the performance in games too much for me, I think. I am okay with downgrading to 13.9, but I'm not sure if that'll fix the problem. Are there any other ways of fixing this problem (with keeping the driver version above 13.8 )?

I'd like to hear from you, and thanks for any upcoming suggestions/answers!

you might want to update the setting. pool settings changed a while ago

stratum.bitcoin.cz
port 3333

[WobbleBoop]

Well, first of all: I don't know how to change the adress in GUIMiner...
Second: I don't think the adress is the problem since my CPU is working without connection problems (I think)...

[RW02]

to change it. instead of selecting slushs pool select other

fill out host as stratum.bitcoin.cz
fill out port 3333
the other settings are the same

also in "flags" stick "-v" this improves the hash rate on amd card

also you have the bugged version of guiminer you need the later one from december https://bitcointalk.org/?topic=3878.0

thanks, my Mhash/s went from 130 up to 170! but I still have the same problem :C

2012-12-03, so: yes

[WobbleBoop]

Do you know a solution to this? (Also I have found that "-v -w128 -f0 AGGRESSION=12 FASTLOOP=false" I think works best as flag)

[RW02]

i think you need to downgrade the drivers. the last set i tried and tested is 13.1 youll have to get them from filehippo.com

type in the seach AMD drivers or AMD drivers 64bit click the drivers and on the right there should be a list of previous drivers click 13.1 and the download on the right

uninstall all current drivers restart computer install 13.1 restart and mining should work

[WobbleBoop]

Well thank you, I'll try. Have you tried every higher version than that? And thank you a lot for helping me I will tell you whenever I'm done, will be tomorrow probably, since I have other stuff to do

[RW02]

sorry nope not tried any later versions. i might boot up one of the old gpu miners but i know nothing from 13.2 to 13.6 works. i spennt weeks trying but just got error and crashes. if you get stuck pm me and ill get back to you as soon as im back online. or just update the thread.

and im happy to help

[WobbleBoop]

Thank you very much, so I can assume you had this problem too? I'll be trying versions out this week, thanks again

EDIT: https://bitcointalk.org/index.php?topic=189101.msg2334100#msg2334100 <- maybe that works, I'll be offline for now too

9/10 times the drivers will downgrade easily and work. if down grade causes a problem there is a tool that removers all traces of amd software much easier than safe mode.

yes i had similar problems but they do vary from package to package 12.8 is guaranteed to work but 13.1 has over 90% success rate and will help with games much more

im trying to keep it a nice balance for you between mining and gaming
installung 13.1 is the best option for now unless you want to try all the old versions of amd drivers (takes me about 30 mines to run a basic test on each driver pack)

[WobbleBoop]

Thanks, I'm installing 13.1 right now.

[WobbleBoop]

13.1 does not work for me... I keep getting a message at the end of the Installation to view the log, the log says, at error messages: "Error: Installation Failed"
Well that sucks...
installing 12.8...

well there probably all going to fail
uninstall all AMD drivers then run this tool
http://downloads.guru3d.com/downloadget.php?id=1275&file=4&evp=7b9d6ae343b65b8df84cc27ec59796f5

this removes anything left over by AMD
Restart and run 13.1 install again and all should work

[WobbleBoop]

Nope I found the problem, even with the "Driver Fusion" thingy there were still 'leftovers' of newer drivers...
Ended up using "Windows Install Cleaner" and it worked... Now using 12.8 because I was too lazy to test 13.1 after it... I will though, later...

Huge thanks for helping me, though can I ask you another favor? (Sorry I've only been mining for like 2 days so I'm quite a n00b):
can you explain  this to me?

The finished and (accepted) shares were even untill around an hour ago (It's 2 hours ago that it started working at all), now I see that the number between the () are way less... Is this really bad? And if so how do I avoid it? (I am using Slush's Pool and both GPU's (2x Sapphire HD 6770s) are using the flags: "-v -w128 -f0"), they both use the same 7 out of 8 cores of my cpu...

[WobbleBoop]

Is there a way to get rid of that if that's bad?
