My T610 has 2x Dell supplied Nanya NT4GC72B8PB0NL-CG sticks which are 4GB dual rank DDR3 RDIMM's capable of running at 133MHz CL-9 timing. These RDIMM's were installed into my T610 by Dell and occupied slots A2 & A3. Only one CPU was installed by Dell, an e5605. The BIOS Memory Mode was set to "Advanced ECC". All this worked without issue of fuss.
I have since aquired 6 Hynix HMT151R7TFR4C-H9 sticks which are 4GB dual rank DDR3 RDIMM's capable of running at 1333Mhz with CL-9 timing. And like a Bull at a gate, i simply removed theDell RDIMMS and slot blanks and installed the Samsung RDIMM's.
Doing this resulted in Configuration warnings and MEMTEST lane failure errors (associated with slots A1 & A4) and as a result i could only see 16GB of RAM. Changing BIOS Memory Mode from "Advanced ECC" to "Optimised Mode" removed the Configuration warnings but i still got MEMTEST failures.
So, i then removed the A1 & A4 RDIMMS and changed BIOS Memory Mode back to "Advanced ECC" and all was well with the server. No POST errors and running Server Configurator Hardware diagnostics Memory (EvLog, Stress, Integ1, Integ2, XMATS32, WCMATS, WCHch, Scan) tests showed that all these tests passed.
Feeling that these 4x Samsung RDIMM's were OK, I changed BIOS Memory Mode to "Optimised mode" and moved these RDIMM's from slots A2, A5, A3 & A6 to slots A1, A4, A2 & A5 (leaving the 2 slots clostest to the CPU free). Unfortunately i got MEMTEST errors and could only see 8GB or RAM.
As a result i don't think the memory is at fault but i'm not sure what is the best way to verify the memory is indeed 100% OK?
How can i further fault find and isolate the issue to the motherboard or processor (remembering i only have one CPU installed)?
Could i install all RDIMMS into A2, A5, A3, A6, B2, B5, B3 & B6 with BIOS set to "Advanced ECC" even though i only have one CPU? No, see this post.
Lastly, how can i get rid of the following messages during POST?
Message PR1: Replaced parts detected... replacement action(s) will not be performed.
Message PR11: Parts Replacement license is not present... replacement action(s) will not be performed.
I undestand that this "Parts Replacement license" is associated with the IDRAC6 and requres a Dell branded uSD card (which i do not have) to be installed into the IDRAC-enterprise (which is installed) for it to be "licensed". Consumer uSD card costs $5 but no doubt cost $50 for the Dell branded uSD card!
