Feature: 1. Nominal and dynamic on-die termination (ODT) for data, strobe, and mask signals. 2. Low-power auto self refresh (LPASR). 3. Data bus inversion (DBI) for data bus. 4. Fixed burst chop (BC) of 4 and burst length (BL) of 8 via the mode register set (MRS). 5. High speed DDR4-2400, 1.2V operating voltage. Specification: HyperX HX424C15FB/8 is a 1G x 64-bit (8GB) DDR4-2400 CL15 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 1G x 8-bit FBGA components per module. Each module supports for Intel Extreme Memory Profiles (for Intel XMP) 2.0. Each module has been tested to run at DDR4-2400 at a low latency timing of 15-15-15 at 1.2V. 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. Fixed burst chop (BC) of 4 and burst length (BL) of 8 via the mode register set (MRS). High speed DDR4-2400, 1.2V operating voltage.

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 Package List: 1 * DDR4 Package List: 1 * DDR4
