Memory Module Speci cations KVR21R15D8/8 8GB 2Rx8 1G x 72-Bit PC4-2133 CL15 Registered w/Parity 288-Pin DIMM DESCRIPTION SPECIFICATIONS ValueRAM s KVR21R15D8/8 is a 1G x 72-bit (8GB) DDR4-2133 CL(IDD) 15 cycles CL15 SDRAM (Synchronous DRAM) registered w/ parity, 2Rx8, Row Cycle Time (tRCmin) 47.05ns(min.) ECC, memory module, based on eighteen 512M x 8-bit FBGA 260ns(min.) Refresh to Active/Refresh components. The SPD is programmed to JEDEC standard Command Time 1x mode (tRFCmin) latency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pin Row Active Time (tRASmin) 33.00ns(min.) DIMM uses gold contact fingers. The electrical and mechanical Maximum Operating Power TBD W* specifications are as follows: UL Rating 94 V - 0 o o Operating Temperature 0 C to +85 C o o Storage Temperature -55 C to +100 C FEATURES *Power will vary depending on the SDRAM used. Power Supply: VDD=1.2V (1.14V to 1.26V) VDDQ = 1.2V (1.14V to 1.26V) VPP - 2.5V (2.375V to 2.75V) VDDSPD=2.25V to 2.75V Functionality and operations comply with the DDR4 SDRAM datasheet 16 internal banks Bank Grouping is applied, and CAS to CAS latency (tCCD L, tCCD S) for the banks in the same or different bank group accesses are available Data transfer rates: PC4-2133, PC4-1866, PC4-1600 Bi-Directional Differential Data Strobe 8 bit pre-fetch Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop) Supports ECC error correction and detection On-Die Termination (ODT) Temperature sensor with integrated SPD This product is in compliance with the RoHS directive. Per DRAM Addressability is supported Internal Vref DQ level generation is available Write CRC is supported at all speed grades CA parity (Command/Address Parity) mode is supported Continued >> kingston.com Document No. VALUERAM1470-001.A00 04/27/15 Page 1MODULE DIMENSIONS Front Back kingston.com Document No. VALUERAM1470-001.A00 Page 2
