A-Tech 4GB DDR3 1066MHz Desktop Module

This A-Tech module provides 4GB of DDR3 memory rated at 1066MHz (PC3-8500). It uses a 240-pin UDIMM form factor and operates at 1.5V with CL7 timing. The single stick is built with major-brand chips and tested for compatibility with a wide range of desktop platforms from vendors such as Dell, HP, Lenovo and ASUS.

Suits DDR3 desktops needing a single 4GB stick

The module fits non-ECC, unbuffered DDR3 desktop slots and works with both AMD and Intel systems that support the PC3-8500 speed grade. It is not intended for laptops, servers requiring registered or ECC memory, or platforms that do not accept standard 240-pin UDIMMs.

Key spec: 240-pin DDR3 1066MHz non-ECC UDIMM

The 240-pin DDR3 interface at 1066MHz with non-ECC, unbuffered operation is the single specification that determines whether this module will work in a given motherboard. Verify that the target system accepts PC3-8500 UDIMMs at 1.5V before purchasing.

Questions about this item

Does my desktop need a 240-pin DDR3 slot to install this module?

Yes, this is a 240-pin DDR3 DIMM that requires a matching desktop motherboard slot.

Can I add this 1066 MHz stick to an existing 1066 MHz DDR3 module?

Yes, both modules will run at the shared 1066 MHz speed and 7 timing if the motherboard supports the same voltage.

How do I confirm the system is using the rated 1066 MHz speed after installation?

Check the memory frequency in BIOS or a system information tool; it should show 1066 MHz with CL7 timing.
