I have a Poweredge 1900 server that uses a PERC 5/i card with its original cache memory module :256-MB DDRII 400MHz ECC-registered DIMM with x16 DRAM components.
Now, the memory module is removable and looks like a standard module. I would like to switch it for a higher density module, say, 512 MB or 1 GB.
After a few searches, I found the following information : Installing unsupported memory causes the system to hang at POST. You have to buy x8 or x16 Memory Modules (for the PERC 5/i).
After harassing a Dell rep for 2 weeks, they came up with the following suggestion :
Now, I have no idea if these are x8 or x16 memory modules. Are they? Also, is there a difference between ECC-Registered and what they are proposing to me?
Thank you for your help.
