Oh, how could I have forget this? If the nVidia driver detects a non-nVidia driver, it does disable some functions, like PhysX, maybe it's disabling OpenCL to! To resolve that problem, you should visit this site:

Topic: [cgminer help] Not detecting all my GPUs (Read 15699 times)
Thanks for the comments.
I understand the AMD cards are going to perform much better than the nVidia card - that's what I added them
. But since the 460 is already in my system I'd like to put it to use anyway.
I tried using both the poclbm and phatk kernels but cgminer still only sees the two AMD cards. Even if I just tell cgminer to list the cards and exit it only reports two cards:
C:\BitCoin\cgminer-1.6.2-win32>cgminer -ndevs
2 GPU devices detected
Any other suggestions for how I might get cgminer to use my 460 card are appreciated.
What happens if you run cgminer with the 2x5770s working normally and then run in another window a 2nd "cgminer -ndevs" after the first is running?I understand the AMD cards are going to perform much better than the nVidia card - that's what I added them

Just a guess, but that's basically what TeaL was saying and I'm wondering if it can't get at the 2x5770s if it will then see the 460?
(no idea just a suggestion to try)

Not to be a dick, but it's only really worth mining with the ATI cards. Additionally, you should be able to point a different instance of CG miner (or any other miner) at a specific GPU.
Your wrong, usually you need 1 instance of CGMiner.I know, I was providing an alternate method to use all of his GPUs, even if a single instance of CG miner cannot detect all of them. He should be able to see if the 460 is detected by running poclbm.py with no additional parameters. If it was still failing to see all of them and he was using Linux I'd try setting export DISPLAY=:0

I'm beginning to suspect the issue is the different OpenCL implementations between AMD and nVidia, I suspect either my operating system or cgminer can only use one OpenCL implementation at a time so it's only able to use one brand of GPU at a time. Anyone know if this is true or not?
I'm a newbie so I can only post here. Could someone please cross post a reference to this help request in the cgminer thread? Thanks.

I'm using cgminer on a Windows 7 x64 system and so far so good. I started out with two NVIDA cards, a 260 and a 460, and cgminer would recognize and use both card with no problem. I recently pulled out the 260 and installed two HD 5770s. I now have 1x460 + 2x5770 installed in my system.
After adding the new card cgminer no longer detects the 460 card, just the two 5770s. Is this a bug in cgminer or do I need to do something to get it to recognize the 460 card?
Thanks in advance.
