Miners Not Detecting HD 5870 Super OC

[c4n10]

Hello everyone,

I recently upgraded to a Gigabyte HD 5870 Super OC and for some reason none of my miners are detecting the card.


I am on Windows XP with the latest version of SDK and CCC download from AMD's homepage. Windows picks the card up just fine but none of my miners will detect the card.

If it helps, in CGMiner the output I get is:

Code:

C:\Documents and Settings\HP_Administrator.YOUR-4DACD0EA75.000\Desktop\cgminer-2
.7.5-win32\cgminer-2.7.5-win32>cgminer --scrypt -o http://lc.ozco.in:9332/ -u c4
n10.3 -p ******* -D -T --verbose --intensity 16 --worksize 128 --shaders 1600

 [2012-10-02 04:54:05] Started cgminer 2.7.5
 [2012-10-02 04:54:05] Error -1001: clGetPlatformsIDs failed (no OpenCL SDK inst
alled?)
 [2012-10-02 04:54:05] clDevicesNum returned error, no GPUs usable

All devices disabled, cannot mine!

Any help is greatly appreciated!!!

I think the newer amd drivers have opencl included, try reinstalling the graphics driver.
Was it working earlier with another ati card? The error indicates it can't detect opencl.

I am using the most current drivers, sdk and CCC available from AMD.

The miners did work before with another card but it was an nvidia card, my geforce 9600 gt oc.

Oh ok,

I run linux so don't know much about windows, but a google search turns up some bad news for you:

It seems amd/ati has dropped opencl support for windows xp in newer drivers/sdk...
You could try an older version (11.12 or 11.4 seems to work, they write in the forums),

Or you need to upgrade to win7 or something or install BAMT on an usbstick.

I see... What search terms did you use because I searched google, here on the forums and the AMD website and never saw those threads, lol...

I will try the older drivers then, thanks!

Ok,

Now, the miners detect my card and work fine for bitcoin mining but scrypt still isn't working.

My cgminer output is stuck here:



Any ideas?

You need to change OSs as scrypt mining requires the SDK 2.6 or newer to work. Or you can do the financially in your best interest thing and mine BTC with that card until LTC is more profitable.

I think I searched "windows xp opencl" first, found something about that it was dropped in newer drivers.
So I searched for "windows xp dropped opencl" and then found the forum links.
