> CPU: 2x Intel Xeon 5100 2GHz > Board: Intel S5000 chipset > RAID5: 3ware 9550SXU-4LP It appears you did not encounter this problem? http://www.3ware.com/kb/article.aspx?id=14932 With regard to the stability issues I raised in the other thread, the korean portal that did should have been in a position to provide proper power supplies and cooling or maybe not. I guess it is safe to say that Woodcrest + FB-DIMM = hot. You may therefore want to go with the board that Joshua is using since he has not encountered stability problems. It does have 64-bit PCI-X slots for your 3ware card.
