DDR 333 / 400 Desktop Memory Upgrade

DDR1 1GB 400MHZ DIMM

What is DDR Desktop Memory?

Double Data Rate Dual In-line Memory Modules are known as DDR-DIMM, DDR DIMM, or most popularly just plain DDR. Double Data Rate interfaces provide two data transfers per differential clock. Unbuffered Dual In-line Memory Modules don't feature address lines and control line buffering, so they cost quite a bit less. However, they may be system-loading limited and are thus generally restricted in the number that can be fitted onto one system. You will find that most unbuffered Dual In-lined Desktop Memory Modules these days can only be installed on one motherboard to a maximum of 4 x 1GB. An interesting and largely unknown aspect of unbuffered DDR Dual In-line Desktop Memory Modulesis that they are able to operate one clock cycle faster than Fully Buffered-Dual In-line Memory Modules.

What is the need of desktop memory upgrade?

A memory upgrade is usually a cost-effective alternative to replacing an older computer. Most often, the computer will slow down in most of its tasks when the memory modules present inside has become insufficient to run current programs. This may be exhibited as slow switching between programs, slow opening and closing of programs and lock-ups on certain programs. If these symptoms are present in the desktop, then it’s time to do a desktop memory upgrade. Performing a memory upgrade your desktop memory modules is one of the most cost effective ways of increasing its performance.

To address the DDR memory upgrade segment, Strontium has the DDR 333 / 400 memory modules for desktops. These memory modules are ideal for users who are looking to do a memory upgrade to their existing desktops with DDR memory, to a higher density and superior performance DDR memory module.

Why Strontium DDR Desktop Memory Upgrade?

All Strontium DDR desktop memory modules are 100% tested to ensure compliance with stringent quality standards and compatibility with all motherboards, making them good choice for your memory upgrade.
