HP Proliant ML110 G6 Server Maximum Memory Configuration – 32GB

One of the most frequently reported drawbacks to using the ML110 G6 Xeon Processor X3430 based servers in a lab environment is the limited amount of memory supported.  HP states “Up to 8GB of memory is available with the removal of the standard 2GB of memory and the optional installation of 4x 2GB PC3-10600 un-buffered ECC DDR3 SDRAM DIMM Memory kits” in their support document HP ProLiant ML110 G6 Server – Configuring Memory.  However, the Intel Xeon Processor X3430 specifications indicate that the CPU maximum memory size (dependent on memory type) is 32GB and the Intel 3420 chipset used by the motherboard also supports 32GB.  It has been widely reported that 16GB works successfully, in fact I have successfully installed 16GB using two of Crucial’s 8GB (4GBx2) memory kits in one of my ML110 G6 Servers, and four Kingston KTH-PL313E/4G modules in another.  But could 32GB work?  Well, I am happy to report that after upgrading my systems I am successfully using 32GB with four Kingston KVR1333D3E9S/8G modules in one of my ML110 G6 servers and four Kingston KTH-PL313E/8G in another.  Important: Kingston KTH-PL313 memory is NOT the same as KTH-PL313E, the later is ECC, Unbuffered/NON-REGISTERED.  Regardless of the brand of memory you purchase it MUST BE Dual Ranked, ECC, Unbuffered/NON-REGISTERED. The Proliant ML110 G6 does not appear to support registered DIMMs. If you prefer to stick with OEM equipment, the correct HP Part Number is 647909-B21.

  1. Hello, Tnx for clearing this up!. I recently got the ML110 G6 and I want to put 32GB of RAM in it, but I can’t figure one thing out. You say it needs unbuffered/NON-REGISTRED ram modules. Is unbuffered and NON-REGISTRED the same thing? So for example: Is unbuffered DIMM the same as UDIMM?

    Tnx. Maarten

    1. Maarten. I’m by no means a memory expert. I outlined the DIMMs that are supported in the article. I wouldn’t deviate from using the ones that I had tested unless the company you purchase them from has a generous return policy. These DIMMs are expensive enough that you generally don’t want to make a mistake by accidentally selecting incompatible memory to save a few dollars. Save time instead.

  2. Everything that I read, says that the ML110 G6 allows for a maximum of 16GB of RAM. The article that you linked also mentions to “Use only HP supported PC3-10600E UDIMM in 1, 2, or 4GB capacities”. But you say it allows for up to 32GB of RAM, which would mean that you are using 8GB modules.. Does this mean that I have to upgrade my chipset in order to increase the maximum RAM capacity?

    1. The chipset of the motherboard in the ML110 G6 supports 32GB, my guess is that HP only offered 16GB so that the ML110 G6 would not compete with other ProLiant offerings at the time. I provided the exact memory modules that work to get you to 32GB.

  3. I know that it is an old thread, but……..
    I have an ML110/G6, and wanted to try the 32GB option. To play it sage, I bought a pair of the Kingston KVR1333D3E9S/8G and a pair of the Kingston KTH-PL313E/8G. The intention was to use whichever one worked and get another pair of same.

    Well, neither one worked in any combination. System only reads up to 2GB (2048M System RAM) and freezes.

    BIOS version is 027 (09/06/2010)
    HP Features Version: 1.08.00
    CPU: Intel Core i3 540 @ 3.07GHz

    I’m thinking of getting the actual HP RAM (Part No. 647909-B21 – HP Compatible 8GB PC3-10600 DDR3-1333 2Rx8 1.35v ECC UDIMM) but the experiment is becoming quite costly.

    Maybe I’ll just stick with 4x4GB – HP 4GB PC3-10600 DDR3-1333 2Rx8 ECC UDIMM (HP PN# 500672-B21) or the Kingston KTH-PL313E/4G 4GB sticks.

    Any suggestions on the actual HP 8GP part – can anyone confirm whether they work for sure?

    Thanks.
