First step passed, I reduced to one 512MB DIMM and a full buildworld with parallel qt build passed. I'll try overnight with the other DIMM to exclude single DIMM failures. But still, I have some more possibilities then, slot1/2 is defect, DIMM 1 does not like co'op with DIMM 2, ECC vs. non ECC (one is marked with ECC support, the other isn't). Will take some hours to find out. Thanks, Andreas
