KF440C19RBA/8 8GB 1G x 64-Bit DDR4-4000 CL19 288-Pin DIMM Continued >> FEATURES FURY KF440C19RBA/8 is a 1G x 64-bit (8GB) DDR4-4000 CL19 SDRAM (Synchronous DRAM) 1Rx8. memory module. based on eight 1G x 8-bit FBGA components per module. Each module kit supports Intel® Extreme Memory Profiles (Intel® XMP) 2.0. Each module has been tested to run at DDR4-4000 at a low latency timing of 19-23-23 at 1.35V. The SPDs are programmed to JEDEC standard latency DDR4-2400 timing of 17-17-17 at 1.2V. Each 288-pin DIMM uses gold contact fingers. The JEDEC standard electrical and mechanical specifications are as follows: CL(IDD) Row Cycle Time (tRCmin) Refresh to Active/Refresh Command Time (tRFCmin) Row Active Time (tRASmin) UL Rating Operating Temperature Storage Temperature 17 cycles 45.75ns(min.) 350ns(min.) 32ns(min.) 94 V - 0 0o C to +70o C -40o C to +85o C FACTORY TIMING PARAMETERS • Default (JEDEC): DDR4-2400 CL17-17-17 @1.2V • XMP Profile #1: DDR4-4000 CL19-23-23 @1.35V • XMP Profile #2: DDR4-3600 CL17-21-21 @1.35V • Power Supply: VDD = 1.2V Typical • VDDQ = 1.2V Typical • VPP = 2.5V Typical • VDDSPD = 2.2V to 3.6V • On-Die termination (ODT) • 16 internal banks; 4 groups of 4 banks each • Bi-Directional Differential Data Strobe • 8 bit pre-fetch • Burst Length (BL) switch on-the-fly BL8 or BC4(Burst Chop) • Height 1.66” (42.2mm). w/heatsink Document No. 4810094A 07/08/21 Page 1 https://www.kingston.com/dataSheets/KF440C19RBA_8.pdf
