Taking up the memory issue raised in other threads, I have reported on this forum that I have had system freezes using all versions of TI and a few whilst not using TI. On the advice given in these other threads, I have just carried out a memory test using the Microsoft Windiag utility on my DDR 400 PC3200 400Mz CAS 2.5-3-3-7 512Mb mem stick. I did approx 10 passes and on each pass a failure ocurred on WMATS+ test. I decided reset my memory in bios from auto to manual and I changed the CAS to 3-3-3-7 and re-ran the test. This time all tests passed OK on 10 passes. My conclusion is that my memory stick is not up to spec. Also, I have noticed that an increase of ambient temperature, causes the system freezes to increase in frequency, so I think it is likely that a out of spec memory, set to auto timing configuration in bios, is a recipe for problems with TI, especially if this is coupled with an under cooled PC!
