16GB DDR3 Kit for ASRock 990FX

This 16GB kit contains two 8GB unbuffered DIMMs rated at 1333MHz with CL9 timings. It is built for ASRock 990FX Extreme9 and Extreme4 motherboards that accept non‑ECC DDR3 memory.

Check your board slots and limits

The motherboard supports a maximum of 64GB across four 240‑pin slots. Verify how many slots are free and whether the BIOS is current enough to recognise 8GB modules before ordering.

Plain green PCB with standard gold fingers

No heat spreader is fitted, so modules sit low under tall coolers. The 1.5V operation matches the board’s default DDR3 voltage, and the 240‑pin edge connector keys only one way into each slot.
