Dell CFT66-RFB is an 8 GB memory module for adding RAM to a compatible computer or server. It is a single 8 GB DIMM, so the capacity comes on one module rather than a kit of separate sticks.
The module uses DDR4 Registered (buffered) memory in a 288-pin DIMM format and runs at 2400 MHz with a rated voltage of 1.2 V. Its single-rank design and Error Correction Code (ECC) support are confirmed for this specific part. EET lists its condition as used or refurbished.
