Hello,
we have workstations of type Z440 with the current bios from August 2018.
In all machines so far 2 RAM bars with each 8GB and a speed of 2.133 Mhz are installed.
Now we want to upgrade the main memory of the machines and have bought the following additional memory:
Kingston KVR24E17S8 / 8 ValueRAM Server Memory (8GB, 2400MHz, DDR4 ECC CL17 DIMM)
According to the operating instructions memory with 2133 and 2,400 MHz can be installed.
Excerpt from the manual:
Memory Type Supported: DDR4, RDIMM (Registered), ECC: 4GB, 8GB, 16GB and 32GB
Memory Speed Supported: 1600MT / s, 1866MT / s, 2133MT / s, and 2400MT / s
Memory Configuration (Supported): Only ECC DIMMs are supported.
These requirements are actually met by the new memories.
If we now install the 4 bars of RAM in the DIM 1,3,6 and 8 slots and start the workstation, the LED will flash and the LED indicator will beep 5 times in total. This is repeated over and over until we turn off the power.
Does anyone know if something needs to be set here or why the RAM is not running?
Are the new memory not compatible?
Must we change anything in the BIOS?
The following pictures shows the original ant the new Ram.
Original 8GB 1Rx4 PC4-2133P-RC0-11
New 8GB 1Rx8 PC4-2400T-ED1-11
The different is 2133P to 2400T. Is this critical?
