Not all cards have a removable DIMM. Obviously the ones with the integrated chips will need the entire card replaced: [IMAGE] [IMAGE] 
I have a T410 poweredge server with a PERC 6/i adapter.  I just replaced the Perc battery and noticed in Open Management Console that error 2320 is showing (once).  Prior to it, error 2319 showed twice.  Error 2320 reads: "Single-bit ECC error. The controller DIMM is critically degraded.: Controller 0 (PERC 6/i Adapter)" The recommended action is to replace the PERC DIMM....I looked in the hardware guide and searched online, I do not even see a DIMM on this controller...the PERC 6/e looks like it has a DIMM but not the 6/i.  I popped open another T410 we have that has the same PERC adapter, and there is no DIMM that I can see on the PERC card.  Also, there are no warnings showing in OMC, just the error recorded... can someone point me to where I would find this DIMM to replace?  A tutorial or replacement guide would be great...the hardware guide doesn't even mention PERC dimm's for this controller.  Is there really an imminent data corruption threat from this?  From what I've read single ECC errors usually correct themselves and are not that big of a deal.  
Replace DIMM on Perc 6/i controller?
