Kingston ValueRAM 8GB PC4-2133 DDR4 Non-ECC CL15 SODIMM 260-pin 1Rx8 Laptop Memory ( Item#: C3994-8 )

ValueRAM's 1G x 64-bit (8GB) DDR4-2133 CL15 SDRAM (Synchronous DRAM), 1Rx8, non-ECC, memory module, based on eight 1G x 8-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR4-2133 timing of 15-15-15 at 1.2V. This 260-pin SODIMM uses gold contact fingers.

Features:
Nominal and dynamic on-die termination (ODT) for data, strobe, and mask signals.
Low-power auto self refresh (LPASR).
Data bus inversion (DBI) for data bus.
On-die VREFDQ generation and calibration.
On-board I2 serial presence-detect (SPD) EEPROM.
High speed DDR4, PC4-2133, 1.2V operating voltage.

About Capacity:
Hard disk/flash memory vendors are using decimal arithmetic: 1MB=1000KB, 1G=1000MB calculated, but the operating system is using binary arithmetic: 1MB=1024KB, 1GB=1024MB. So there are some differences between display capacity and nominal capacity of hard disk/flash memory products. However, this is allowed to exist. Please do not doubt his authenticity.
8G=approximately 7.5GB, 16GB=approximately 14GB, 32GB=approximately 29GB, 40GB=approximately 37GB, 60GB=approximately 55GB, 80GB=approximately 74GB, 120GB=approximately 111GB, 160GB=approximately 149GB, 250GB=approximately 232GB, 320GB=approximately 298GB, 500GB=approximately 465GB, 640GB=approximately 595GB, 1TB=approximately 930GB
