8GB DDR4 Kit for Supermicro Servers

This two-module kit delivers 8GB of DDR4-2133 memory in a 2x4GB configuration. It is built specifically for Supermicro 5019S-L, X11SSL-F, X11SSH-F and X11SSZ-QF systems. The unbuffered, non-ECC DIMMs suit administrators upgrading compatible Supermicro platforms that accept standard UDIMMs.

64GB System Limit and Speed Behaviour

The supported platforms cap total memory at 64GB across four sockets, so this kit occupies half the available slots. Faster modules will automatically clock down to 2133, 1866 or 1600MHz depending on the processor and population, ensuring stable operation without manual tuning.

Matched Pair for Dual-Channel Operation

The package supplies two identical 4GB sticks tested together, enabling dual-channel bandwidth on the supported boards. Installing matched pairs avoids timing mismatches that can occur when mixing x4 and x8 modules within the same bank, a restriction noted for these platforms.

Questions about this item

Will these 2133 MHz DDR4 modules run correctly with my existing 1600 MHz or 1866 MHz DDR4 DIMMs in the Supermicro X11SSL-F?

Faster memory clocks down to the optimal speed and voltage for the processor and module count installed, so the 2133 MHz kit will operate at the lower speed of any slower DIMMs already present.

How can I confirm the 8 GB kit is recognised at 2133 MHz with CL15 timing after installation?

Check the BIOS memory information or an OS tool such as dmidecode; it should report 8 GB total, 2133 MT/s data rate and 15-15-15 CAS latency for each 4 GB module.

Does the package contain only the two 4 GB DIMMs or are any cables or brackets included?

The box includes exactly two 288-pin DDR4 UDIMM sticks; no cables, brackets or additional hardware are supplied.
