'Tis grand to mix Ram and ram speeds as long all all DIMMS either match or
exceed FSB and also as long as they are BOTH either non-ECC or ECC.
Could one be registered and the other unregged? you will see this by a
missing middle Mem module denoting unregistered Ram...
What mobo is it? If it is an 815e chipset board, then you will have problems
with 4x4 4x8 or 4x16 double-sided DIMMS..
Last resort also would be to try the system with just one DIMM in at a time
to rule out that the new DIMM is not gone the way of the Duck..

Subject: [ILUG] bad memory..
In recently bought an extra 128Mb SD-RAM (133Mhz) to add to the 128Mb
(100Mhz) I already have. However, the system is now unstable and does
everything from locking up to completely rebooting itself. I have tried
fiddling with the BIOS settings to set the RAM speed to 100Mhz. This did
no good. Without the RAM the system is ok and never crashes. Any
solutions? Is it ok to mix RAM speeds? Or is the new RAM i bought from a
kernel 2.4., redhat 7.1
