About this kit
- 1. Strict testing: In order to avoid disputes between the two parties, check the specifications of the device before purchasing. For example, computer motherboard model / CPU / RAM model/RAM slot/RAM frequency/maximum compatible memory capacity.
- 2. Memory Speed=PC4-21300 (2666MHz), ECC Type=Non-ECC, Form Factor=DIMM, Pin Count=288 Pins, Voltage=1.2V, Rank and Configuration=1Rx8 or 2Rx8, Timings=CL-19.
- 3. Fast heat dissipation: Adopting aluminium alloy heat sink to increase heat dissipation and prevent static electricity, which is more friendly to motherboard/CPU.
- 4. 2666MHz RAM can downclock to 2133MHz or 2400MHz if your computer system specification only supports 2133MHz or 2400MHz.
- 5. Please contact our service staff if you have any questions, we will sort it out within 24 hours. Thanks for choosing us. Wish a happy shopping experience.
