I'm upgrading a PowerEdge T310 to its maximum allowed memory of 32GB. 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:
• Single-rank and dual-rank RDIMMs of sizes 2-GB, 4-GB and 8-GB are supported for a total of up to 24 GB.
• Quad-rank RDIMMs are supported for a total of up to 32 GB.
• 1-GB and 2-GB UDIMMs are supported for a total of up to 8 GB.
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).
