8GB DDR4 2133MHz Module

This 8GB DDR4 module runs at 2133MHz with a CL15 latency and 1.20V operation. It is an unbuffered, non-ECC DIMM built with major brand chips for desktop systems. The 288-pin design fits standard DDR4 slots on compatible AMD and Intel platforms.

PC4-17000 Standard Limits

The DDR4 2133 standard (PC4-17000) sets the tested frequency at 2133 MT/s with a CL15 timing at 1.20V. Systems that only support lower DDR4 speeds will downclock this module automatically. Mixed populations with faster or slower modules will run at the lowest common speed and loosest timings.

Simple DIMM Installation

Installation requires aligning the notch on the 288-pin module with the slot key and pressing firmly until the retention clips engage. Common issues include the module not seating fully on one side, mixing non-ECC with ECC memory, or exceeding the motherboard's maximum supported capacity per slot.

Questions about this item

Will this 288-pin DDR4 module fit in my desktop motherboard?

This is a standard 288-pin DDR4 DIMM. It fits any desktop board with a DDR4 slot that accepts unbuffered non-ECC memory at 1.2 V.

My system specifies PC4-17000 speed. Does this match?

Yes. The module runs at 2133 MHz, which is the PC4-17000 data rate. It will operate at that speed or downclock if your board only supports a lower DDR4 frequency.

Is this the correct replacement for the Lenovo 4X70G88313 part?

The supplier lists it as a compatible equivalent for the IBM-Lenovo 4X70G88313 module, matching the 8 GB capacity, DDR4 2133 speed, and 1.2 V unbuffered specification.
