None of the GPU miners find my GPU

[Eliovp]

I've been searching for days now, and haven't found a solution for this problem.

I've got a windows machine here, with a GTX680

I've done a clean install of the graphic drivers, tried with multiple versions..
I've installed the cuda toolkit.

First i've tried to run cgminer which gave me this error:

Started cgminer 3.6.6
Error -1001: clGetPlatformsIDs failed (no OpenCL SDK installed?)
clDevicesNum returned error, no GPUs usable
All devices disabled, cannot mine!


Next try was the cudaminer, again an error:

Unable to query CUDA driver version! Is an nVidia driver installed?


Last try was the bfgminer which gave me this one.

NO DEVICES FOUND: Press 'M' and '+' to add



In other words, it's like my gnu is playing hide and seek.. which is working on my nerves..

I really hope someone can help me out here!
I would "Greatly" appreciate!

Did you install latest Nvidia driver?

With 314.22 I had same issue.. then got latest one, and voila!

Thx for the reply.

Yup, got the latest ones.. even tried older ones.. nothing works

Weird.. I have 332.21 drivers, and cudaminer works fine (on 560Ti).

Same one here..

Only thing I could suggest, if all other options are correct - is to try to remove drivers from safe-mode, with some utility like Drive Sweeper, or similar (google: nvidia driver remove), and try to reinstall it.

I should have mentioned that in my first post.. already tried that..

The only thing i can think of, is that it has something to do with Windows 8..

And i know.. i would go to 7 if i could.. but that's not an option..

But thx anyway!

same here with my r9 280x msi card, it only finds it when monitor is attached to the card and bios setting is on automatic for vga primary display all under win7 maybe better with win8 or linux ? I would like to have monitor on mb internal gpu and r9 280x no monitor and mining only, how to set this up to make it work?

You either need a dummy plug to fool windows into thinking the graphics card is hooked to a monitor or edit registry:

I'm mining with on Windows my two 5850's and didn't ever thought about need to use the dummy plugs, it isn't needed!
You just need to disable ULPS - this mechanism disables the second card without monitor/workload. Here's how to do it:

Go to registry and disable Ulps:

 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Cl ass\{4D36E968-E325-11CE-BFC1-08002BE10318}]

 and change "EnableUlps" to 0 under the 0000 and 0001 or 0003 keys.

I'd try here:

If you can't get cudaMiner to work then I don't know what will...

[qosmio]

there is no EnableUlps in my registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Cl ass\{4D36E968-E325-11CE-BFC1-08002BE10318}
please help
edit:...ok found it with search registry it was in 0001

disable Ulps did not help but dummy plug on vga out did
