Description
Kingston 64GB DDR5-6400MT/s ECC Reg CL52 RDIMM 2R Server Memory For AMD Threadripper 7000, 9000 Series KSM64R52BD4-64HA
Kingston's KSM64R52BD4-64MD is a 8G x 80-bit (64GB) DDR5-6400 CL52 SDRAM (Synchronous DRAM), 2Rx4, ECC, memory module, based on forty 4G x 4-bit FBGA components. The SPD is programmed to JEDEC standard latency DDR5-6400 timing of 52-52-52 at 1.1V. Each 288-pin DIMM uses gold contact fingers. The electrical and mechanical specifications are as follows:
Features
- Power Supply: VDD = 1.1V Typical
- VDDQ = 1.1V Typical
- VPP = 1.8V Typical
- VDDSPD = 1.8V to 2.0V
- On-Die ECC
- x80 ECC (x40, 2 independent I/O sub channels)
- 32 internal banks
- Hard/Soft Post Package Repair
- Sideband access with I3C/I2C
- PCB: Height 1.23" (31.25mm)
- RoHS Compliant and Halogen-Free
RAM speeds were traditionally listed in MHz (e.g. DDR4 3200MHz or DDR5 6000MHz). Today, the industry standard is MT/s (megatransfers per second), so you'll now see speeds shown as DDR4 3200MT/s or DDR5 6000MT/s.
What does MT/s mean?
MT/s measures the number of data transfers a memory module can perform each second, making it a more accurate way to express RAM performance.
In practice, a module labelled 3200MHz is the same speed as 3200MT/s - only the terminology has changed.
