Topic: Mining with 6850 ok but my 5850 crashes cgminer (Read 1620 times)
installed the 2.8 drivers and it's back up and running. i'm now getting 322 out of my 5850 at I 18
Ok now I'm stuffed. Uninstalling the drivers and putting 12.8 on has messed things up completely. Installing 13.5 does not help either.
Help.
Help.
After installing 12.8 drivers i get the following from GPU-Z
---------------------------
GPU-Z
---------------------------
ATI OpenCL driver bug detected, skipping OpenCL detection.
Uninstall the AMD Stream SDK / OpenCL driver to re-enable this functionality.
---------------------------
OK
---------------------------
any ideas?
I have the AMD-APP-SDK-v2.5-Windows-641.exe should i instal this as well?

My screen is back now at a resolution of 640 x 400. Hmm nice
After installing the 12.8 drivers do I need to install anything else to get the open cl working?

Tried it without the installer and it messed up. Now trying the uninstall utility but my screens are no longer working. Time to reboot.
And try a reinstall of the 12.8 drivers

Make sure you use Catalyst Un-install Utility to remove all stuff.
Good luck!
Good luck!
is it overheat?
try to start in a good ventilation
It's only running at 62 C Adding this has made my 6850 go up a couple of degrees though but I expected that when it sits above the 5850 try to start in a good ventilation
no joy with those settings. still getting hardware errors. It may be time to downgrade my drivers
That was my thinking, I thought this card could do a lot better.
If i put the intensity above 12 it just gets a hardware error.
I'm thinking about removing the 13.5 drivers and putting on the 12.8 drivers
Is it as simple as uninstalling the 13.5 drivers re-booting and then putting on the 12.8 drivers.
I've seen a lot of issues re-installing the drivers.
Afterburner only allows me to clock this GPU to 775 MHz It's running at 765MHz with a mem clock of 1050 MHz
I'll give your settings a go

Thank you.
That's work a treat. Now just need to try and increase the 5850 to above 250kh/s may have to play with core MHz and see if anything's been messed with it.
Looking at CPU z it looks like the 5850 is using hardly any ram compared to my 6850
I thought scrypt was memory intensive
5850 should be running at least 350khash/sThat's work a treat. Now just need to try and increase the 5850 to above 250kh/s may have to play with core MHz and see if anything's been messed with it.

I got the same card and running with these parameters: thread_concurrency 5824 -I 19 -worksize 256, and I'm getting 400khash/s (overclocked)
From my experience, 12.8 is best for scrypt mining.

an asic would be great but there's such a long waiting list it's not going to be worth it.
If you know of a good place to get one i would.
Mining litecoins is more profitable for me.

ok just tried 3.1.1 and it's running but CGMiner displays a hardware error on the 5850 card and display invalid nonce.
i've put the 13.5 drivers on and it made no difference
i've set the intensity to 11 and that seems to work i can up it to 12 but no more than that.
My 6850 could run at 18 ok
My 5850 gets me 255kh/s and my 6850 gets me 127kh/s
I was getting 215kh/s out of my 6850 on it's own.
any way to set individual settings for the intensity?

Just add --intensity 18,12
Same thing with all the other values if you have more then one card you have to put in different values for each card especially when you got different versions.
i run my 5870s and 6950s on the 12.8 drivers without issues.

Thank you both. I'll try 3.1.1 and if it fails ill try the 13.5 beta drivers.
Do I have to uninstall the other drivers before putting on the beta ones.

13.4 are bugged. Install 13.5 beta, or oldest 13.1/13.3 beta.
Try cgminer 3.1.1
