4GB DDR4 2400MHz Desktop Module

This A-Tech module provides 4GB of DDR4 memory at 2400MHz with a CL17 latency and standard 1.2V operation. It uses a 288-pin DIMM form factor and is built with major brand chips. The unbuffered, non-ECC design suits standard desktop motherboards. It is listed as a compatible equivalent for the IBM-Lenovo 4X70M60571 part number.

Suits Basic Desktop Upgrades

This single 4GB stick works well for restoring a system to its original specification or adding modest capacity to an office PC. It is not intended for high-performance workloads, multi-channel tuning, or builds requiring ECC or registered memory. Users needing greater bandwidth or larger total capacity should consider higher-density kits or faster speed grades instead.

Speed Decides Compatibility

The tested frequency of 2400MHz (PC4-19200) is the critical figure that determines whether this module matches your motherboard and processor memory controller. Verify that your platform supports DDR4-2400 before purchasing, as installing a different speed grade can prevent boot or force a lower clock.

Questions about this item

What type of DIMM slot must my desktop motherboard have for this 288-pin DDR4 module?

The module uses a standard 288-pin DDR4 DIMM form factor, so the motherboard must provide a matching DDR4 DIMM slot.

Can I install this CL17 2400MHz stick alongside slower DDR4 modules already in my system?

Yes, it will run at the speed and latency of the slowest installed module, so mixing with slower DDR4 DIMMs is supported.

How can I confirm the RAM is operating at the rated 2400MHz frequency after installation?

Check the memory frequency in your system BIOS or a tool like CPU-Z; it should report 2400MHz for this module.
