Kvr29S21D8/32 D4 Nb 32Gb 2933
Description
This document describes ValueRAM's KVR29S21D8/32 is a 4G x
64-bit (32GB) DDR4-2933 CL21 SDRAM (Synchronous DRAM),
2Rx8, non-ECC, memory module, based on sixteen 2G x 8-bit
FBGA components. The SPD is programmed to JEDEC standard
latency DDR4-2933 timing of 21-21-21 at 1.2V. This 260-pin DIMM
uses gold contact fingers. The electrical and mechanical
specifications are as follows:
