Re: CGMINER GPU bitforce overclock monitor fanspeed RPC in C linux/windows/osx 2.2.0
2 gpus. 5770 and internal 4250 (set as primary). And no problems with this setup and v2.1.2. Driver installed in XP is 11.12 and 2.5 sdk, nothing else.
Okay so what's happening here is that the ATI display library is finding both GPUs but opencl is only finding one GPU... Now look at this post:
I just had an annoying multi-hour debugging session, trying to figure out why cgminer thinks there's only one GPU in my (Debian Testing) system.
$ aticonfig --list-ad
* 0. 06:00.0 ATI Radeon HD 5800 Series
1. 07:00.0 ATI Radeon HD 5800 Series
2. 08:00.0 ATI Radeon HD 5450
Turns out that AMD is being stupid. Again.
OpenCL 1.1 AMD-APP-SDK-v2.4 (595.10) (don't remember where I downloaded it from): library works.
OpenCL 1.2 AMD-APP (831.4) (available from http://developer.amd.com/sdks/AMDAPPSDK/Pages/default.aspx ) does NOT see more than one GPU.
You can extract the build number etc. from the library with
$ strings -a /pth/to/the/library.so | grep "^OpenCL.*AMD-APP"

Yes I realise that's a linux report but it could be related.
Next, download this bleeding edge build http://ck.kolivas.org/apps/cgminer/temp/cgminer.exe
and try this command:
cgminer.exe --ndevs
