Product Description & Reviews
Specification: Brand: KKmoon Model: KVR21N15S8/4 Speed: DDR4 2133 Storage Capacity: 4G,8G,16G (Optional) Type: 288-pin SDRAM Bandwidth: PC4-2133 Rank: Single-rank Power Supply: VDD=1.2V Typical PCB: Height 1.23" (31.25mm) CL(IDD): 15 cycles Row Cycle Time (tRCmin): 46.5ns(min.) Refresh to Active/Refresh: 260ns(min.) Row Active Time (tRASmin): 32ns(min.) Maximum Operating Power: TBD W* UL Rating: 94 V - 0 Operating Temperature: 0℃ to +85℃ Storage Temperature：-55℃~+100℃ Item weight: 17.8g / 0.62oz Item size: 13.3 * 3.1 * 0.1cm / 5.23 * 1.22 * 0.03in (L * W * H) Package weight: 26.6g / 0.94oz Package size: 14 * 4.5 * 1cm / 5.51 * 1.77 * 0.39in (L * W * H)Package List: 1 * Memory module 1 * User manual (English and Chinese)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
