Comments:
  • 23/10/2017 - Thanks to our customer Tony Wong for confirming that this system can take 8GB EUDIMM modules and not just the 4GB modules as per original HP specs.
  • Also confirmed via this post on the HP Forum.
  • DDR3-1333 modules automatically clock down to 1066MHz and 800MHz depending on which Intel Xeon model is used and the number of modules installed.
  • If 4GB is installed, the recognized memory may be reduced to 3.5GB or less (depending on system configuration and memory allocation).
  • Maximum configurations require a 64-bit operating system.
  • Please refer to the system manual for proper installation of DIMMs for Single, Dual, and Triple Channel configurations.
  • Intel Xeon 3500 Series processors support up to 3 channel of DDR3 memory.
  • At least 1 DIMM must be installed into each channel for full performance
