 Installed ati-stream-sdk-v2.1-vista-win7-64.exe, but phoenix 1.7.4 won't work.  ???
 Have this in command promt:
 File "phoenix.py", line 124, in <module>
 File "Miner.pyc", line 128, in start
 File "phoenix.py", line 112, in makeKernel
 File "kernels\poclbm\__init__.py", line 22, in <module>
   import pyopencl as cl
 File "zipextimporter.pyc", line 82, in load_module
 File "pyopencl\__init__.pyc", line 3, in <module>
 File "zipextimporter.pyc", line 98, in load_module
ImportError: MemoryLoadLibrary failed loading pyopencl\_cl.pyd

 Just tried 2.1 on WinXP and its working just fine. Probably installer issue with 7 x64.

For some reason, I had the same problem with sdk 2.1 on win7. The way I solved it? I installed a different version of SDK alongside it (2.4-2.6). For whatever reason, 2.1 is installed in a program files directory while 2.4-2.6 install in the windows\system32 and windows\SysWOW64 directory; could be possible the miners are looking in the windows dir for OpenCL GPGPU applications and if it finds it there, it'll query what devices/platforms are available. I know GUIMiner refused to even find 2.1 until I did this. I now have 2.1 + 2.6 on my gaming pc and 2.1 + 2.5 on my other miners.

 Thanks, I'll try it asap. But 2.4-2.6 SDK's should overwrite 2.1 version, no? 2.1 install opencl.dll in windows directory, but other dll's aren't installed (they hang in program files (x86)).

Maybe you misunderstand. ATI Stream (2.1) installs, by default, into "C:\Program Files (x86)\ATI Stream", and includes its own OpenCL 1.0. AMD APP 2.4-2.6, however, installs it's software + OpenCL 1.1 dll's into C:\Windows\System32 and C:\Windows\SysWOW64 (contrary to what it appears, the 64-bit version installs into System32 and 32-bit installs into SysWOW64). Having both installed will not interfere with differing OpenCL versions or anything.

TL;DR: They are 100% seperate and safe to install together. They do not overwrite each other.

Ok, installed both 2.1 and 2.4. ATI Stream platform (2.1) doesn't work, APP platform (2.4) has the same cpu bug. Thanks for the try anyway.

Works fine for me, unless you have 6xxx series cards, then it -requires- 2.4+ sdk.

 I have 5770 and use phoenix 1.7.4 with phatk2 kernel. By running it with 2.1 I have command prompt window opened for a few seconds (use cmd files), then its shutting down without any message. However by using poclbm its saying about error in kernel.

 Hey, but you still have cpu usage bug. One core is still used, or maybe these apps consume so much. Anyway, I have zero cpu usage on XP with 10.6/2.4/2.1:

 And always 25% load (one core fully loaded) on 4-core cpu in Win7 64, no matter what drivers/sdk I use. I have same bug on XP if 2.5 sdk and 10.7-11.11 drivers used. Cpu usage should be at zero.

Nope, no CPU bug. The CPU is only running at 800MHz, and I have 6 instances of gpu-z polling for gpu data + speedfan + VNC active. You can see 4 phoenix running and they all use 0% CPU
