Manufacturer description

The A-Tech 2GB DDR PC3200 kit is a simple memory upgrade for an older desktop or a retro PC build. You get two 1GB modules in the standard 184-pin DIMM form factor, both rated at 400MHz. If your motherboard takes first-generation DDR, this pair fills two slots with a matched 2GB total. That is a practical amount for a Windows XP-era machine or an older workstation you want to keep running. The modules come as a two-piece kit, so you get two identical sticks instead of mixing whatever spares are in the parts bin. That matters on boards that run in dual-channel mode.

Frequently Asked Questions

Will this A-Tech kit work in my computer?

It works only in desktops with 184-pin DDR (DDR1) DIMM slots that support PC3200/400MHz memory and 1GB modules. Check your motherboard or system manual for supported memory type, speed and the largest module size per slot.

How much memory is in the kit?

The kit has 2GB total: two 1GB DDR PC3200 desktop modules, each a 184-pin DIMM rated at 400MHz.

Can I use these modules in a laptop?

No. These are full-size 184-pin desktop DIMMs. Laptops use smaller SO-DIMM modules, which are physically different and not interchangeable.

Will DDR PC3200 fit in a DDR2 or DDR3 motherboard?

No. DDR, DDR2 and DDR3 modules have different pin counts and notch positions, so this 184-pin DDR kit only fits boards built for first-generation DDR memory.

What warranty and support come with this memory?

A-Tech lists a lifetime warranty and toll-free technical support for this kit. Check the product listing or A-Tech directly for the full warranty terms and how to file a claim.
