Ran memtst+ for 6 hours on the two 4GiB sticks. It found two problems. Tst Pass Fail Addr Location Good Bad Err Count 5 3 0002A453310 676.3MB ffffffe7 fffffff7 00000010 1 5 3 0002E4532f0 740.3MB ffffffe7 fffffff7 00000010 2 At least it's GSkill memory with lifetime warranty. Could this single bit error somehow correlate with the address in RCX?
