Won't take any memory, what is up??????

[rik]

Also from the Dell website:

NOTE: Only 100-MHz DIMMs are supported. The system can include both ECC and non-ECC memory; however, to support ECC, all installed DIMMs must be ECC-capable. ECC DIMMs have an odd number of memory chips on the module and non-ECC DIMMs have an even number of chips.

This is from the users guides on that particular system. It can be found here:
