8GB DDR4 ECC SODIMM for server laptops

This 8GB DDR4 2400MHz ECC SODIMM module uses major-brand chips and runs at the standard 1.2V voltage. It is built as an unbuffered 260-pin SO-DIMM with a CL17 latency profile. The stick is tested for reliability in server and workstation systems.

Suits technicians upgrading Lenovo workstations

The module matches the IBM-Lenovo 4X70Q27988 part number and supports both AMD and Intel platforms that accept DDR4 ECC SODIMMs. Buyers whose systems require registered DIMMs or non-ECC memory should look at something else. Compatibility must be verified against the host system specifications before purchase.

ECC unbuffered operation decides fit

Error-correcting code with unbuffered signalling is the single specification that determines whether this part works in a given slot. Systems wired for registered ECC or for non-ECC memory will not accept this module.

商品問答

Should I choose the 8GB DDR4 2400 ECC SODIMM or a different capacity for my upgrade?

This module provides 8GB in a single 260-pin DDR4 SO-DIMM. Select it when your system has an open slot and the maximum supported capacity per slot is 8GB or higher.

What does the 2400MHz rating mean once the module is installed in a laptop or server?

The memory will run at DDR4 2400 (PC4-19200) with CL17 latency at 1.2V, delivering the rated bandwidth provided the platform supports that speed and ECC unbuffered operation.

Is the 260-pin DDR4 SO-DIMM interface compatible with standard laptop slots and what does it limit?

Yes, it fits any DDR4 260-pin SO-DIMM socket. The interface caps transfer rate to PC4-19200 and requires the host to support ECC unbuffered modules for error correction to function.
