1) Message boards : Number crunching : what level CAT driver should I use to get MW to run on 4870 (Message 61349) Posted 7 Mar 2014 by Venz Post: Btw where did GPU-Z warn you about the bug? It is the first screen to show, before the standard main screen. Also - Restarted system no problem. Finished PG Sieve no problem, (pending) System running normal It's busy eating galaxy chunks right now. (MW) They must not be very filling, it sure is eating alot of them 4870 is saying mmmmmmm....., :)

Uninstall the AMD STREam SDK................. end quote I removed AMD app sdk through CAT program in add remove programs then installed AMD app sdk 2.7 name - AMD-APP-SDK-v2.7-Windows-641 Same problem in gpu-z and boinc put the above "quote" into search engine lead me to this website http://mrlithium.blogspot.com/2013/03/opencl-hassles-ati-opencl-driver-bug.html It had the following fix Quoting from Mrlithium's blog THE FIX: 1. Uninstall any AMD Stream SDK you have right now. 2. Delete amdocl.dll and opencl.dll from C:\windows\system32 and C:\windows\Syswow64. 3. Reinstall the AMD Stream SDK you have. Does not matter which one (I think) 4. Check to make sure the amdocl.dll and opencl.dll files you just deleted have not come back. 5. Check in C:\Program Files (x86)\AMD APP\bin\x86 and C:\Program Files (x86)\AMD APP\bin\x86_64 to make sure the files are there in that location instead. This is where they should be. 6. Try using GPU-z to see if there is a tickmark next to OpenCL. If there is, all should be well, and you can continue to use Reaper/CGminer/GUIMiner to mine bitcoins/litecoins/etc. Or any OpenCL program for that matter. 7. For some reason I had to delete the kernel files that reaper/cgminer had generated such as litecoin-reaperv13.Cayman-256-5760-2.bin but I am not sure that this was due to OpenCL because I tried unlocking my Radeon 6950 GPU to a 6970 (and succeeded, link here) So it may have just been that the number of shaders or something was wrong. End quote from Mrlithium's blog I only did step 2 alone. **** Have not restarted computer yet. Shut down boinc Restarted boinc it then showed opencl 1.0 support for 4870 in the start up log. It seems I now also have opencl cpu support version 2.0 sse2 now, I don't recall seeing that before I think that happened from the developer amd app sdk 2.7 install Able to run opencl in MW Able to run opencl in Seti Astropulse opencl 1.00 Able to run opencl primegrid opencl that is so far....... None of which could be ran before Running CAT 13.9 with developer SDK 2.7 gpu-z running with opencl checked. Thanks has to go to Mr.Lithium's blog and the efforts of trying to make some coin. Why those drivers stopped things, and how they got there I don't know (maybe from previous graphics card, from igp before that, from previous driver installs, from original win7, don't know). I now know that step 2 alone has worked for my scenario. Everything so far seems to be running normal, will inform if things change. Venz out

Downloaded driver 13.9 - running right now and does not work MW WUs. driver package ver = 8.97.100.11-130429a-158498C-ATI Bought 4870 online with no base drivers supplied.
