DVM26R2T4/32G is a registered 4Gx72 memory
module, which conforms to JEDEC's DDR4-2666,
PC4-2666 standard. The assembly is Dual-Rank.
Each rank is comprised of eighteen 2Gbx4 DDR4­2666 SDRAMs.

One EEPROM is used for Serial Presence Detect
and a combination register/PLL, with Address and
Command Parity, is also used.

Both output driver strength and input termination
impedance are programmable to maintain signal
integrity on the I/O signals in a Fly-by topology.

A thermal sensor accurately monitors the DIMM
module and can prevent exceeding the maximum
operating temperature of 95C.

Notes

Tolerances on all dimensions
except where otherwise
indicated are .13 (.005).
