Question :

I'm upgrading a PowerEdge T310 to its maximum allowed memory of 32 GB.the compatibility information in the manual lists the following :

Your system supports DDR3 registered DIMMs (RDIMMs) or unbuffered ECC DIMMs (UDIMMs).Single and dual-rank DIMMs can be 1067 - or 1333 -MHz, and quad-rank DIMMs can be 800 - or 1067 -MHz.your system supports single-channel mode and dual-channel mode.the system contains a total of six memory sockets.UDIMM supports single-rank and dual-rank DIMMs.only RDIMM supports quad-rank DIMMs.the maximum memory that is supported on your system varies according to the types and sizes of memory modules being used :

The system is currently fitted with 4x PC3L-10600 (unbuffered, non-ECC) modules of 4GB each.

If i read this information correctly, i should be able to upgrade this with 4x PC3L-10600R modules of 8GB each, maxing out the available memory and giving me the benefits of ECC.

The memory new i purchased, reading directly from the label on the sticks, is" 8GB 2RX4 PC3L-10600R-9-10-E1"(Hynix HMT31GR7BFR4A )

After installing the new memory, the system will not POST, and the front LEDs have diagnostic lights 1 and 4 lit.i installed the new sticks into the exact same slots (channels A and B, slots 1 and 2 ) as the previous memory.

Returning the original memory leads to a normal boot.

I need to know if i've somehow purchased the wrong memory by misreading the information, or if my new memory is faulty somehow (I'd expect a later error, rather than an outright boot failure in this case).


Answer 1 :

Take a look at the technical data sheet for your memory.

Specifically, the HMT31GR7BFR4A you have is dual -rank, not quad -rank.

Your system probably does not support dual-ranked 8 GB for 32 GB total (assuming your manual is correct, as it's a bit different from this technical guidebook ).you'd want HMT31GR7BFR8A, which is quad-ranked 8 GB.

Also note from the technical guidebook :

T310 supports x8 (data width) and does not support x4 and x16 DRAM on RDIMM

You're attempting to install 2 Rx4.HMT31GR7BFR8A is 4 Rx8 so i'd expect it to satisfy these requirements.

Of course, other manufacturers (e.g.Samsung) also make RDIMMs in that configuration.


Answer 2 :

Diagnostic lights 1 and 4 means system board failure.either you have the incorrect RAM, A bad ram stick or a bad system board.i looked at the firmware updates and none address an issue with ram.


Answer 3 :

The manual excerpt you provided statesSingle-rank and dual-rank RDIMMs of sizes 2-GB, 4-GB and 8-GB are supported for a total of up to 24 GB.

Your modules are 8GB dual-rank RDIMMS, and exceed the 24GB maximum as per the manual.try with 3 modules.
