4GB DDR4 2133 Desktop Module

This 4GB DDR4 2133 CL15 DIMM is built as a compatible replacement for G.Skill F4-2133C15D-8GVR kits. It runs at 2133 MHz with standard 1.20 V operation. The unbuffered non-ECC design fits typical consumer desktop boards. A-Tech tests every module before it ships.

Suits Single-Slot Upgrades

The single 4GB stick works well for a basic capacity bump on a board with a free 288-pin slot. Users needing dual-channel bandwidth or 8GB and up should look at a matched kit instead. Systems that require registered or ECC memory cannot use this module.

CL15 CAS Latency at 2133 MHz

The CL15 timing at 2133 MHz sets the access speed for this module. If your platform demands tighter latency or a higher data rate this part will not meet that requirement. Verify the motherboard qualification list before ordering.

Questions about this item

Should I pick the 4GB single module or look for a larger kit?

This listing is a single 4GB DDR4 2133 CL15 DIMM. Add one module if your board has a free slot and you only need a small capacity boost; choose a matched kit of two or more modules if you want dual-channel bandwidth or a higher total capacity.

What does the 2133 MHz rating actually deliver in my desktop?

The module runs at 2133 MHz with CL15 latency at the standard 1.20 V. In a real system it will operate at the highest speed your motherboard and CPU memory controller both support, which may be 2133 MHz or a lower JEDEC frequency if the platform cannot run that fast.

Will the 288-pin DDR4 DIMM fit my motherboard's memory slots?

Yes — the stick uses the standard 288-pin DDR4 DIMM form factor (PC4-17000) and is unbuffered non-ECC, so it fits any desktop board with DDR4 slots that accept 1.20 V UDIMMs.
