Their JEDEC (#8) is rated 2400, as reported by CPU-Z, if I didn't misunderstand what you called "slowest JEDEC". Following is the relevant section from CPU-Z: DIMM # 1 SMBus address 0x50 Memory type DDR4 Module format UDIMM ..... Size 8192 MBytes Max bandwidth DDR4-3200 (1600 MHz) Max JEDEC DDR4-2400 (1200 MHz) .... Nominal Voltage 1.20 Volts ....
