The Samsung M396B4G73DB0-YF8M1 is a 32GB DDR3 memory module for IBM Power 770 and 780 servers. It is a custom 276-pin DIMM, called a CDIMM, and it runs at 1066 MT/s. It does not fit standard Dell, HP, or Lenovo servers.

Reading M396B4G73DB0-YF8M1

  • M396: Samsung's standard registered DIMMs start with M393 and load-reduced ones with M386. The 96 marks a different, IBM-style module.
  • B: DDR3 memory.
  • 4G7: a 4G by 72-bit layout, which is 32GB with ECC.
  • 3: x8 memory chips.
  • D: D-die, Samsung's fifth-generation DRAM die.
  • B: flip-chip package.
  • YF8: DDR3-1066 at CL7, rated for 1.35V.
  • M1: an extra suffix seen on these IBM builds.

This build and the BH0 build

Feature M396B4G73DB0-YF8M1 (this module) M396B4G73BH0-YF8M1
DRAM die D-die, 5th generation B-die, 3rd generation
Package Flip chip Standard FBGA
Capacity 32GB 32GB
Speed code YF8 (DDR3-1066, CL7) YF8 (DDR3-1066, CL7)

Both are 32GB IBM Power memory with the same speed code. Only the DRAM die and the package differ. When you replace a module, match the part number on the ones already installed.

Where it fits

IBM's Power 770 and Power 780 servers use 276-pin DDR3 DIMMs, and each DIMM has its own memory buffer. Each processor card has 16 DIMM slots running at 1066 MHz. IBM sold the 32GB size in sets of four: feature 5602 on POWER7 and EM42 on POWER7+. Four modules make 128GB. Sixteen make 512GB.

IBM sells this memory as Capacity Upgrade on Demand, so check your server's activations and IBM's feature list before you plan an upgrade.

Why some listings disagree

Some sellers show 1333MHz, CL9, and 1.5V for this module. Those numbers do not match Samsung's YF8 code or IBM's documents, which both point to 1066MHz. At 1066 MT/s the module moves 8.5 GB/s.

Quick answers

Is it the same as the BH0 module?

No. The part numbers differ, and so do the DRAM die and package. They do the same job in the same IBM servers.

Does it work in a standard server?

No. The 276-pin connector is an IBM Power design, and standard boards use 240 pins for DDR3.
