32GB DDR3 kit for ASRock Z68 boards

This 32GB kit contains four 8GB DDR3 1600 modules built for ASRock Z68 Pro3-M, Z68 Pro3 Gen3 and Z68 Extreme7 Gen3 motherboards. Each stick is unbuffered, non-ECC and runs at 1.5V with CL11 timings. The 240-pin DIMMs fill all four memory slots on these platforms.

Upgrade from lower-capacity DDR3 sets

Replacing a 2x4GB or 2x8GB kit with this 4x8GB configuration doubles or quadruples total memory without changing voltage or speed. The jump is worthwhile when workloads exceed the previous limit and the board’s four slots are free. No higher-density DDR3 modules are supported on these chipsets.

DDR3 1600 ceiling on Z68 platform

The Z68 memory controller tops out at DDR3 1600, so faster DDR3 modules will downclock to this speed. Four ranks per channel can limit overclocking headroom and may require relaxed timings. Builders needing more than 32GB or faster transfer rates must change platform.

Questions about this item

Will the 240-pin DDR3 modules fit the four memory slots on my Asrock Z68 Pro3-M board?

Yes, the kit provides four 240-pin DDR3 DIMMs that match the board's four slots and 32 GB maximum capacity.

What BIOS setting should I check after installing the 1600 MHz CL11 sticks so they run at the rated speed?

Enable the XMP or DOCP profile in the BIOS; otherwise the modules will default to a lower JEDEC frequency.

Do the unbuffered non-ECC sticks need any periodic cleaning or firmware updates during their service life?

No routine cleaning or firmware updates are required; the modules are covered by a limited lifetime warranty for exchange if a fault appears.
