  • Unbuffered non-ECC design fits standard desktop motherboards

Kit contents and target build

This kit supplies eight gigabytes of DDR4 desktop memory in two matched four gigabyte modules. It is intended for standard desktop boards that accept unbuffered non ECC DIMMs at the DDR4 3200 data rate. Builders who need higher capacity or registered ECC modules should choose a different kit.

Speed grade and timing

The modules run at DDR4 3200 which corresponds to PC4 25600 bandwidth. CAS latency is specified at CL22. This timing figure is the key parameter to match against the motherboard qualified vendor list for guaranteed operation.

Thermal behaviour under load

Operating voltage is 1.2 volts which keeps heat output modest during extended workloads. The unbuffered design does not add register delay so sustained throughput remains stable as long as the system provides adequate airflow over the DIMM slots.

Questions about this item

What does the 3200 speed rating mean once the kit is installed?

The modules run at DDR4 3200 (PC4 25600) data rate with CL22 latency at 1.2 V, giving the system that peak transfer bandwidth when the memory controller supports it.

Which interface standard do these DIMMs use and what does it limit?

They use the DDR4 interface, which caps the maximum data rate at 3200 MT/s and the voltage at 1.2 V for this kit.

What physical slot and clearance do the sticks need?

Each stick is a standard unbuffered DDR4 DIMM that fits a desktop DDR4 slot; the low-profile height clears most CPU coolers.
