  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Timing11-11-11
  • Voltage1.5V
  • 8 GB total capacity in a 2 × 4 GB kit
  • DDR3 1600 MHz speed rated at PC3 12800
  • CL11 latency with 11-11-11 timings at 1.5 V
  • Guaranteed compatibility with ASRock 970 Extreme 3 and Extreme 4 boards
  • Unbuffered non-ECC 240-pin DIMMs using major brand chips

Targeted upgrade kit

This 8 GB kit contains two 4 GB DDR3-1600 modules built to match ASRock 970 Extreme 3 and 970 Extreme4 motherboards. Each stick runs at 1.5 V with CL11 11-11-11 timings and uses unbuffered non-ECC 240-pin DIMMs. The dual-channel pair suits owners of those boards who need a straightforward capacity increase.

Compatibility assurance

Computer Memory Solutions validates every module against the listed ASRock models so the kit installs without manual voltage or timing changes. The pack includes only the two memory sticks; no extra cables, brackets or software are supplied. Builders who want RGB lighting, heat spreaders or ECC error correction will not find those features here.

Everyday fit

Standard-height 240-pin DIMMs slot directly into the four DDR3 sockets on the target boards, leaving clearance for most CPU coolers. Major-brand chips and a limited lifetime warranty from the manufacturer back long-term reliability. Systems that require registered memory, higher frequencies than 1600 MHz or capacities beyond 64 GB total are not supported by this kit.

Questions about this item

Will the 240-pin DDR3 modules need any replacement over time?

The kit contains two unbuffered non-ECC DIMMs rated for 1.5 V with a limited lifetime warranty from the manufacturer, so no scheduled replacement is required.

What speed ceiling appears first when the memory runs continuously at DDR3-1600 CL11?

The modules operate at 1600 MHz with 11-11-11 timings at 1.5 V; sustained loads stay within that rated frequency and voltage envelope.

How much heat or noise do the two 4 GB sticks produce during all-day use?

Without heat spreaders the DIMMs rely on case airflow, draw only 1.5 V each, and have no moving parts, so they add negligible heat and zero noise.
