Description
This document describes ValueRAM's 1G x 64-bit (8GB) DDR4-2400 CL17 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 DDR4-2400 timing of 17-17-17 at 1.2V. This 260-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
| CL(IDD) | 17 cycles |
| Row Cycle Time(tRCmin) | 45.75ns(min.) |
| Refresh to Active/Refresh Command Time (tRFCmin) | 350ns(min.) |
| Row Active Time(tRASmin) | 32ns(min.) |
| Maximum Operating Power | TBD W* |
| UL Rating | 94 V-0 |
| Operating Temperature | 0° C to +85° C |
| Storage Temperature | -55° C to +100° C |
