KF426C16BB/4 4GB 512M x 64-Bit DDR4-2666 CL16 288-Pin DIMM Continued >> FEATURES FURY KF426C16BB/4 is a 512M x 64-bit (4GB) DDR4-2666 CL16 SDRAM (Synchronous DRAM) 1Rx8, memory module, based on eight 512M 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 DDR4-2666 at a low latency timing of 16-18-18 at 1.2V. Additional timing parameters are shown in the Plug-N-Play (PnP) Timing Parameters section below. 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 16 cycles 45.75ns(min.) 260ns(min.) 29.25ns(min.) 94 V - 0 0o C to +85o C -55o C to +100o C FACTORY TIMING PARAMETERS • Default (Plug N Play): DDR4-2666 CL16-18-18 @ 1.2V • XMP Profile #1: DDR4-2666 CL16-18-18 @ 1.2V • 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 1.34” (34mm), w/heatsink Document No. 4809910A 06/22/21 Page 1
