I thought this would be the best place to ask concerning my worries. I ran Memtest86, the newest version, on my rather recently acquired system. I have 2x256 DDR400 Ram by twinmos, running in dual channel mode.

I got 175 errors in Test5, which has the following description:

Test 5 [Block move, 64 moves, cached]
This test stresses memory by using block move (movsl) instructions
and is based on Robert Redelmeier's burnBX test. Memory is initialized
with shifting patterns that are inverted every 8 bytes. Then 4MB blocks
of memory are moved around using the movsl instruction. After the moves
are completed the data patterns are checked. Because the data is checked
only after the memory moves are completed it is not possible to know
where the error occurred. The addresses reported are only for where the
bad pattern was found. Since the moves are constrained to a 8MB segment
of memory the failing address will always be lest than 8MB away from the
reported address. Errors from this test are not used to calculate
BadRAM patterns.

I haven't noticed any problems using my system despite these errors, but would this be a reason to exchange my RAM for new modules? Or are this type of error common, even with working RAM modules?

Thanks!
