you shouldn't blame system sellers for chipset manufacturers' faults.
this is what you can do:
1. set the DRAM timings to conservative setting in the bios
2. insert ONE module
3. boot memtest86+ (http://www.memtest.org/
) and test the memory
4. repeat 3. and 4. as long as there are untested modules
5. report back with the results
If you email me include [WIMSBIOS] in the subject.
