I can with single modules, but not with 2.. I don't know what to do... thanks for all of the comments/suggestions ----- Original Message ----- From: "John Bradford" To: "Brien" Cc: "John Bradford" ; Sent: Wednesday, April 16, 2003 3:28 PM Subject: Re: my dual channel DDR 400 RAM won't work on any linux distro > > I've now tried running the following configurations > > [snip] > > > and all of them have the same problem: black screen after kernel loads > > they all do seem to test with errors when ran with another module, but they > > also DO NOT test as errors when they're alone > > OK...
