Compatible Supermicro Server Memory

This 8 GB kit contains two 4 GB DDR3 1066 SO-DIMM modules built for Supermicro C7X58, X8SAX, X8ST3-F and X8STE motherboards. The unbuffered, non-ECC sticks run at 1.5 V with CL7 timings and use major-brand chipsets under the Computer Memory Solutions guarantee.

Suited for matched-pair upgrades

The modules must be installed in pairs to enable dual-channel operation on the supported boards. Builders who need ECC error correction, registered DIMMs, higher speeds or larger single-module capacities should look at a different specification.

204-pin DDR3 1066 SO-DIMM form factor

Each stick is a 204-pin SO-DIMM rated at PC3-8500 with 2Rx8 organisation. This physical and electrical interface is the single specification that determines whether the kit will fit and function in the target Supermicro systems.

Questions about this item

Should I pick the 2x4GB kit or a single 8GB stick for my Supermicro board?

The kit contains two 4GB modules that must be installed in pairs for dual-channel operation on the C7X58, X8SAX, X8ST3-F or X8STE boards.

What does the 1066 MHz speed actually deliver in my system?

The modules run at 1066 MHz (PC3 8500) with CL7 timing and 1.5 V, providing the rated bandwidth when the motherboard supports that frequency.

Will the 204-pin SO-DIMM fit the 240-pin slots on my X8SAX?

No, this kit uses 204-pin DDR3 SO-DIMMs, while the listed Supermicro boards require 240-pin DIMMs, so they are physically incompatible.
