Greetings.

So the typical reasons why a whole channel will not show/recognize dimms are:

• Unsupported DIMMs (are the PIDs listed in memory section from https://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-c-series-rack-servers/c220m3-sff-specsheet.pdf)
• Not adhering to memory population rules
  • When single- and dual-rank DIMMs are populated for 2DPC, always populate the dual-rank
    DIMM in the blue DIMM slot and the single-rank DIMM in the black DIMM slot
  • Larger capacity DIMMs go in lower numbered slot (i.e. D1 larger capacity DIMM.  Smaller DIMM in slot D2) if mixing sizes.
• Is server running up to date FIrmware

Hi Kirk

thanks for ur reply

H1/H2 DIMMs are recognized but D1/D2 Nope , i used the same RAM model

[Kirk J]

If you swap H1/H2 with D1/D2 do you get the same results?

I did it bro before i post here ,it works well

[Kirk J]

So it seems to be more of a slot issue, D1,D2 not recognising anything.  Does SEL log show any alerts/errors for those slots?
