The Chinese server-wannabee manufacturers products just can't handle the load that these modules puts on the system. They are very much aware of it, but their tech support never admits that it's their crappy motherboard designs that causes the stability problems, instead the come up with all sorts of strange excuses and finally closes all support requests with: "not able to reproduce here - no fault" /Martin
