ATP A4B32QB4BNRCSE
32GB DDR4-2400 REGISTERED ECC DIMM
DESCRIPTION
The ATP A4B32QB4BNRCSE is a high performance 32GB DDR4-2400 Registered ECC SDRAM memory
module. It is organized as 4096M x 72 in a 288-pin Dual-In-Line Memory Module (DIMM) package. The
module utilizes thirty-six 2048Mx4 DDR4 SDRAMs in FBGA package. The module consists of a 512-byte
serial EEPROM, which contains the module configuration information.
