TWIN2X2048-8500C5D Issue (1 of 2 sticks is bad)

"A" = Good Stick

"B" = Bad Stick

 

I think one of two memory sticks is bad after I ran memory test with memtest 1.70. I tried putting "B" stick in all different slots for each test unfortunately it's still failed. "A" stick is good after 2 passed test in all different slots.

 

After 2 test:

"A" (Single Channel) @ 1066 MHz

5-5-5-15 = PASSED - 4042 MB/s

5-5-6-15 = PASSED - 4042 MB/s

5-7-7-24 (SPD) = PASSED - 3905 MB/s

 

"B" (Single Channel) @ 1066 MHz

5-5-5-15 = FAILED - 4042 MB/s

5-5-6-15 = PASSED - 4042 MB/s

5-7-7-24 (SPD) = PASSED - 3905 MB/s

 

"A" & "B" (Dual Channel) @ 1066 MHz

5-5-5-15 = FAILED - 5328 MB/s

5-5-6-15 = PASSED - 5328 MB/s

5-7-7-24 (SPD) = PASSED - 5101 MB/s

 

5-5-5-15 and 5-5-6-15 are similar speed but 5-5-6-15 isn't acceptable.
