System-Specific DDR3 Kit for Supermicro

This 4 GB kit contains two unbuffered 2 GB DDR3-1066 DIMMs tested for Supermicro C7X58, X8SAX, X8ST3-F and X8STE motherboards. Each module runs at 1.5 V with CL7 7-7-7 timings and uses a 2Rx8 organisation. The 240-pin form factor fits the six DIMM slots on these boards.

Capacity and headroom for legacy servers

The pair delivers 4 GB total, suitable for light virtualization, file serving or workstation duties on the supported platforms. Dual-channel operation requires paired installation; triple-channel mode needs three identical modules. Maximum platform capacity is 24 GB across six sockets, so this kit leaves room for further matched pairs.

Upgrade path from smaller DDR3 sets

It replaces single 2 GB sticks or mismatched pairs that force single-channel mode. The jump is worth it when the board reports less than 3.5 GB usable under a 64-bit OS or when dual-channel bandwidth is needed for memory-bound workloads. Buyers needing ECC, registered modules or capacities above 24 GB cannot use this kit.

Questions about this item

Will these 240-pin DDR3 1066 CL7 modules work in the same Supermicro X8SAX board that currently runs 1333 MHz sticks?

The kit is validated for the X8SAX at 1066 MHz; the board also accepts 1333 MHz modules, so mixing speeds will force all channels to run at 1066 MHz.

How can I confirm the kit is running in dual-channel mode after installing the pair in my X8ST3-F?

Install one stick in each channel pair, then check the BIOS memory summary or CPU-Z — it should show 4 GB total at 1066 MHz with dual-channel active.

Does the package include only the two 2 GB DIMMs, or are heat spreaders and any tools supplied?

The box contains the two 240-pin DDR3 DIMMs only; no heat spreaders, screws or installation tools are included.
