Let us use this thread to discuss problems, features, speed, RAM-requirements and what-ever comes to mind when crunching DC-projects using computers with Win 8. :colbert: I have today downloaded and installed Win 8 Pro on one of my crunchers. I am using the latest BOINC-version (7.0.28, 64-bit) and running WCG, Einstein@home, LHC, Seti and Collatz. The computer is an i7-860 running @ 3.4 GHz on an ASUS-mobo (forget which ... ), 6 GByte of RAM and two Radeon 7850 GPUs. A standard 1.5TB HDD and DVD-RW. As of the last 3 hours no problems at all; all WUs have gone through well and I have the impression that the crunching time for each WU is not so much different.
