The Samsung M396B4G73BH0-YF8M1 is a 32GB DDR3 memory module for IBM Power 770 and 780 servers. Sellers list it as IBM part 41T8258. It is a custom 276-pin DIMM, called a CDIMM, and it runs at 1066 MT/s.

CDIMM or standard DIMM?

Feature Standard server DIMM This IBM CDIMM
Pins 240 for DDR3 276
Buffering Register chip on the module A memory buffer for each DIMM
Fits Dell, HP, Lenovo, and other x86 servers IBM Power servers

A standard DDR3 module can't seat in a Power 770 slot, and this module can't seat in an x86 board. Check the label and your system's feature list before you plan a swap.

The numbers sellers use

Sellers list this Samsung module under IBM part 41T8258 and tie it to memory feature 5602 on the Power 770. IBM sold feature 5602 as four 32GB DIMMs at 1066 MHz, which is 128GB. The Power 770 and 780 have 16 DIMM slots on each processor card, so sixteen of these modules make 512GB.

Reading the YF8 code

Samsung's speed code YF8 means DDR3-1066 at CL7, with a 1.35V rating. The B in BH0 marks B-die, Samsung's third-generation DRAM die, in a standard package. The DB0 build uses D-die in a flip-chip package instead. Size and speed are the same.

Quick answers

Will it work in a Dell or HP server?

No. It is built for IBM Power systems only.

Is it for POWER8?

No. Sellers list POWER8 CDIMMs at 1600MHz under other numbers, such as IBM 00LP736. This module runs at 1066MHz.

Is the 1333MHz in some listings right?

No. IBM's documents and Samsung's code both say 1066MHz.

Is it the same as the DB0 module?

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

What does CUoD mean?

Capacity Upgrade on Demand. IBM sells the memory as capacity you switch on with activations, so check your server's activations first.
