Memory problems -- memtest86 gives anomalous results

hi SF gurus,

i have a homebuilt computer, ASUS P6T6 mobo with 6x2 GB of RAM, Intel Core i7 CPU. i ran memtest86+ 4.20 and observed the following: although all 6 2 GB memory sticks are seen and listed on the memtest screen, it says i only have 8 GB of total memory. yet, when the tests were run, instead of going up to 12 GB, or stopping at 8 GB, it tests up to 9216 MB and then goes on to the next test, in every case. no errors were reported, but does this indicate there actually *is* a memory problem? also, given that no errors were reported up to 8 (actually 9) GB, can i assume that the problem is in sticks 4 or 5 (or the corresponding slots on the motherboard)?

thanks in advance for any thoughts.

Definitely worth investigating. A simple solution would be testing the RAM modules one at a time instead of all together.

If each one passes without errors, then take one and test it in each slot successively.

Then test two together, then (let's say) four and then all six, each time keeping an eye on the reported amount of memory and the actual amount tested. Does the issue return?
