Compatible DDR3 Kit for ASRock 970 and B85 Boards

This 8 GB kit contains two 4 GB DDR3 modules built to run at 1600 MHz with CL11 timings. It is validated for ASRock 970 Pro2, B85 Pro4, B85iCafe4 and B85M Pro4 motherboards. The unbuffered non-ECC DIMMs install directly into standard 240-pin slots. Builders upgrading those specific platforms can add capacity without compatibility guesswork.

Steady Operation at 1.5 V Without Heat Spreaders

The modules operate at the standard 1.5 V DDR3 voltage and carry no heat spreaders, keeping the profile low for tight CPU cooler clearance. Under sustained workloads the chips run at their rated 11-11-11 timings without active cooling. Systems that load all four slots up to the board maximum of 32 GB will see consistent throughput because each stick uses a single 1Rx8 rank.

Low-Profile 240-Pin DIMMs for Everyday Builds

Each stick uses a standard 240-pin DDR3 edge connector and omits a heat spreader, so it fits beneath most tower coolers and in compact chassis. The two-module kit populates a pair of slots for dual-channel bandwidth on supported boards. Buyers needing ECC error correction or registered buffering for server-grade stability should look elsewhere, as this kit provides neither.

Questions about this item

How much power do these 1.5 V DDR3 modules draw when the system runs all day?

Each stick operates at the standard 1.5 V DDR3 voltage, so total power draw stays within normal DDR3 limits for an 8 GB kit.

What motherboard slot type must I already have for this 240-pin kit to fit?

You need a board with four 240-pin DDR3 DIMM sockets, such as the ASRock 970 Pro2, B85 Pro4, B85iCafe4 or B85M Pro4.

Can I keep my existing DDR3 sticks and add this 2 x 4 GB kit without mixing speeds?

Yes, the CL11 1600 MHz modules will run at the speed of the slowest installed DDR3 memory, so older sticks stay compatible.
