Fully compatible replacement for Kingston DDR 3 Server Memory Model KVR16R11D4/16I

Five years ago I purchased Kingston server RAM with the following specs:

Kingston ValueRAM 16GB 240-Pin DDR3 SDRAM ECC Registered DDR3 1600 Server Memory (Intel Validated ) Model KVR16R11D4/16I

I understand that this RAM is no longer being made and it is now becoming increasingly difficult to find this RAM.

What model of Kingston RAM has replaced this model of memory and will be fully compatible within an Intel S2600cp server system board that already contains 8 sticks of this RAM?

I need to purchase 8 more sticks of this RAM that will be used on the same Intel S2600cp server system board and I need to make sure that both types of RAM are fully compatible and work without any problems for a Server 2016 Data Center OS that will be running on this server system board.
