I just bought 4 new sticks of RAM tonight. After a kernel panic I ran Rember to test the sticks and see if they were causing a problem. It immediately came up with 2 problems. Does anyone know what it means? Should I return the RAM ASAP? Stuck Address: FAILURE: possible bad address line at offset 0x1d9ac488 Solid Bits: FAILURE: 0xfffffffff != oxfffffffd at offset 0x0e8c0170 Everything else came up "ok." If one or more of the sticks is bad, is there a way to tell which one from this info, or must I run the rest on 1 stick at a time to find out? Also, is there a way, besides Apple Hardware Test, to find out if maybe the problem is with a RAM slot, and not with the stick? Thanks for all you help.
