There were several ways we were able to determine stability. 1. restart the system several times and see if it posted correctly and without kicking on the watch dog. 2. Memtest host programs over an extended period of time 3. Load windows cleanly without corruption errors. 4. Run burn in with applications such as Intel CPU Diag tool and Sisoft Sandra for an extended period of time without BSOD's. 5. Run Premiere or Cubase with test projects including encoding without errors for a long period of time without errors. One of the major benefits the Cuda based applications such as Premiere CS5/6 and Pro Audio applications with low latency Asio drivers is the intensive load on the ram. The ram is constantly buffered to and updated besides the usual read write operations. This often finds issues with latency timings on the ram because if the read, write, erase, and refresh timings are off, then you are going to have corruption and application crashes. With audio the data corruption comes across as distorted audio from the audio engine. You can also duplicate some of this by Overclocking the CPU some to see if the stability remains with certain applications because the CPU handles the memory management. We were able to detect errors consistently and without failure with these methods especially the latency timing compatibility issues. The biggest challenge the new Memory controller CPU architecture brought to the table is syncing the host controller to the modules across a bus effected by heat, signal attenuation, and Voltage regulation. This requires the controller and the board to re-detect memory timings every time the board boots up from a non-powered or powered state along with maintaining voltage levels with a very fine margin of fluctuation. The Board manufacturers have to adjust that detection based on modules in the market and considering the scope of modules, that is no small challenge. Now add to that Quad channel and changes/version differences in the host controllers ie Memory controllers and you have the current problems you see today in the memory compatibility. Eric ADK
