8GB DDR3 1866MHz Desktop Module

This A-Tech module provides 8GB of DDR3 memory at 1866MHz with PC3-14900 rating. It uses a 240-pin DIMM form factor and operates at the standard 1.50V voltage. The unbuffered, non-ECC design suits standard desktop motherboards.

Ideal for DDR3 system upgrades

Owners of desktops that accept DDR3 1866MHz UDIMMs can use this to add capacity or replace a failed stick. It also serves as a direct replacement for the listed Samsung part numbers. Systems requiring ECC, registered modules, or a different DDR generation cannot use this memory.

1866MHz DDR3 speed rating

The tested 1866MHz frequency and PC3-14900 designation determine whether the module matches the motherboard's supported memory standard. Verify the platform documentation for this exact speed before purchase.

Questions about this item

Will this 8 GB DDR3 1866 MHz DIMM fit a desktop motherboard that uses 240-pin slots?

Yes, the module is a standard 240-pin DDR3 DIMM and will physically fit any desktop board with DDR3 slots.

Does the module require a specific voltage setting in the BIOS?

It operates at the standard 1.5 V for DDR3, so most boards will configure it automatically without manual adjustment.

Can I use this stick alongside my existing Samsung M378B1G73DB0-CMA module?

The product is listed as a compatible replacement for that Samsung part number, so it should work in the same system.
