Capacity and compatibility

This kit provides 64GB of DDR4 memory in four 16GB DIMMs rated at 2666MHz with CL19 timings. It is validated for ASUS RS100-E10-PI2, RS300-E10-PS4 and RS300-E10-RS4 servers and listed as compatible with Biostar TUF B450-PLUS GAMING, TUF B450-PRO GAMING and BCM BC370Q motherboards.

Platform checks before purchase

Confirm that your motherboard has four 288-pin DDR4 slots and supports non-ECC unbuffered modules running at 1.2V. The system maximum capacity is 128GB across four sockets, so this kit fills all slots on a four-socket board. A 64-bit operating system is required to address more than 4GB of memory.

Build and daily use

Modules use major-brand chipsets in a 2Rx8 configuration without heat spreaders, keeping the profile low for tight server chassis. Unbuffered DIMMs install directly into standard 288-pin slots; all memory will run at the speed of the slowest installed module or CPU capability, so matching pairs are recommended for best performance.

Questions about this item

What is included in the box and is anything else needed for installation?

The box contains four 16 GB DDR4 DIMM modules totalling 64 GB. No extra parts are required; install them into the server's 288-pin DDR4 slots.

Which kit capacity should I choose for the RS100-E10-PI2 server?

The RS100-E10-PI2 supports a maximum of 128 GB across four sockets, so this 64 GB (4×16 GB) kit fills half the capacity and leaves room for future expansion.

What does the 2666 MHz rating mean once the memory is installed in the server?

The modules will run at up to 2666 MHz (PC4-21300) with CL19 timing at 1.2 V, provided the processor and motherboard support that speed; otherwise they operate at the highest mutually supported frequency.
