Overview:

ValueRAM's KVR21R15S8/4I is a 512M x 72-bit (4GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM) registered w/parity, 1Rx8, ECC, Intel Compatibility Tested, memory module, based on nine 512M x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2133 timing of 15-15-15 at 1.2V. Each 288-pin DIMM uses gold contact fingers.

Features:

• 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

Compatible Systems:

• Intel - S2600CW Server
• Intel - S2600KP Server
• Intel - S2600TP Server
• Intel - S2600WT Server
