Hey all, So I can mine BTC fine, but I want to mine LTC....but I always crash. I have tried using multiple configurations in guiminer scrypt, reaper, and CGminer. I have a sapphire 7950. It came clocked like this: GPU Clock: 925 Memory Clock: 1250 VDDC: 1250 This card is in a PCI 2.0 X16 express slot I have 8GB of Ram. My best success is using the high usage in setting in Guiminer-scrypt....sometimes I can up to 3 hours before it crashes, at about 530khash/sec. I am using the 13.4 Catalyst Drivers and I think the 2.8 SDK Whenever I try to reinstall the SDK I get a failure....not sure if that is because I upgraded to 13.4 catalyst. Any ideas? I never go over 75 celcius and my PSU is 730W If I run CGminer...my comp crashes If I run guiminer scrypt I get stuck on compiling kernal and if I try reaper I get this: http://anonymouse.org/cgi-bin/anon-www.cgi/http://img90.imageshack.us/img90/8959/reaperfail.png

Slight update....I wiped all my drivers and went to reinstall catalyst 13.4 and I got an error when I installed SDK 2.8
AMD APP SDK SamplesFinal Status: Fail Version of Item: 2.8.1016.5 Size: 130 Mbytes
EDIT: Wouldn't let me install the SDK samples because there was an old folder in my documents. I deleted that and now it installed. Still having my issues.
I guess my real question is, should I uninstall my drivers and go to an older version? If so which catalyst and sdk drivers are people using successfully?

Hmmmmm Try the following, use cgminer: First delete your .conf file in the cgminer folder (back it up somewhere else if you want) Open cmd, type: setx GPU_MAX_ALLOC_PERCENT 100 Then press return and close cmd. Then open a fresh cmd, CD to your cgminer folder and then input the following: cgminer --scrypt -o yourpool -u yourusername -p yourpassword -s 2 --expiry 1 --queue 0 --thread-concurrency 8192 -I 13 -w 256 -g 2 Press return and let me know what happens

update: Hashrate keeps dropping to about 120 then climbs up to 300ish and then up and downThe only conf file I have is an example.conf Also I wasn't sure what you meant by "CD" to cgminer and type that stuff. So I made a new Batch file with what you said...not sure if that gives the same effect. Anyway it is running...hasn't crashed yet http://anonymouse.org/cgi-bin/anon-www.cgi/http://img32.imageshack.us/img32/9035/newtestk.png

I have the exact problem as reported in this thread (except I have a 6850) but the solution doesn't work for me. Any other ideas?

Try using drivers 12.8 Avoid the new ones

I had problems with 13.4...wouldn't start up and would just crash. Reverted back to 13.1 and everything works fine. Try an older driver

I tried a whole bunch of drivers and a whole bunch of miners, and nothing ever worked on my machine (brand new install of W7). I finally gave up. I had the same problem though, they'd all just crash with a ".exe stopped working" message.

Then open a fresh cmd, CD to your cgminer folder and then input the following: cgminer --scrypt -o yourpool -u yourusername -p yourpassword -s 2 --expiry 1 --queue 0 --thread-concurrency 8192 -I 13 -w 256 -g 2 Press return and let me know what happens Did you do the above ? It's an important step.

Yes, those were the exact steps I followed. Like the OP I also only had example.conf. The "setx GPU_MAX_ALLOC_PERCENT 100" command returned okay. cgminer just crashes when I try to use it with --scrypt.

Just realized CD means change directory... I get Pool 0 slow/down ....so I will try again with a different mining server Hmmmmm Try the following, use cgminer: First delete your .conf file in the cgminer folder (back it up somewhere else if you want) Open cmd, type: setx GPU_MAX_ALLOC_PERCENT 100 Then press return and close cmd. Then open a fresh cmd, CD to your cgminer folder and then input the following: cgminer --scrypt -o yourpool -u yourusername -p yourpassword -s 2 --expiry 1 --queue 0 --thread-concurrency 8192 -I 13 -w 256 -g 2 Press return and let me know what happens

13.1 is verified good Not for me. cgminer wouldn't even start Also lots of members are getting solid results (including myself) with 12.8 seems that it is the best option right now

Seems that the several installs / removals corrupted something. Do a fresh install of Windows and go for 12.8 straight away

After following the above method this what I got.... http://img401.imageshack.us/img401/2623/testnewnew.png? I'll let this run and see if it crashes after a while. I should also note the low hashrate...but I'll play with that later if this works. Would the setting max gpu be required every time?

If it's crashing it's probably down to thread concurrency - Have a look for the thread concurrency others have been using for your card. Yeah that low hashrate is a bit strange. Play around with your GPU clock speeds, set it even lower, then keep going up and hashrate should increase, then suddenly decrease. When it decrease just keep backing up 1Mhz at a time and you should find the sweet spot. You should also decrease your core voltage, try 1100mV, it will get temps down (i know they are already low, but they will go up when your hashrate increases). Setting max gpu is needed everytime you restart your PC, but not every time you restart cgminer. Also make sure the page file thingy has been set correctly on your PC - i was having loads of problems till i realised it was set to 0 - so i changed it to the max permitable of my main HDD and all was good Edit - also try varying the value of -s --expiry --thread-concurrency, see if that helps. You could also try higher intensities but i don't think that will be the issue. Don't forget though, if you go for a high intesnity, you will probably need to use -g 1 rather than 2

I had several issues when trying to mine with the 13.xx series. Do yourself a favor, waste less than an hour reinstall the damn thing and go straight for 12.8. That's what I would do.
