Get your PC upgrade from Memory Deal ! Upto 4GB per RAM module ...

So you are ready to take the 4GB RAM memory plunge... 4096MB is great! Your PC or Mac computer, notebook or server will run faster then ever. There are a few things to consider before you buy and upgrade to 4GB. What speed do you need, ddr or ddr2? Do you upgrade in pairs? Will your computer even see the total RAM of 4GB? Some notebooks only see a total of 3GB so be sure your computer system can use the extra upgrade to "4 GB of RAM."

OSX MacBook Pro notebooks can utilize the 4GB memory capacity.

Find out if your PC is running 32bit or 64bit version of Windows.... Watch the video here on this page by: Pirillo.com

If you are running a desktop, laptop or notebook PC and need 2GB modules please see the 2GB ram memory upgrade page . Or you can see below as we list 4gb kits.

Servers....... load them up!

There are three types of memory found in the 4gb memory module capacity.

Fully Buffered DIMM modules usually have heat-sheild some call them heat-sink or heatspreaders. FBDIMM modules use an advanced memory buffer (AMB) to maintain signal integrity and improve error detection. This high-performance DDR2 4GB FB-DIMM memory module is well suited to server applications because it virtually eliminates traditional stub-bus density/speed limitations. ECC error handling and correction increases data reliability. This is the newest memory module type to offer single modules that are as large as 4gb.

*Keep it simple and look for the heatspreader. Fat ones for MacPro and thin ones for everything else.

Servers use these 4GB DDR2 RDIMM upgrades and because of their huge need for memory. Ram for these IT backbones shows the need for 4gb and even larger modules as common. DDR2 Registered DIMM or RDIMM memory modules isolate the command, address, and clock signals, which reduces system loading and allows a greater number of modules on a given system. RDIMM memory also include ECC error handling and correction, increasing data reliability.

DDR (1) ECC Registered DIMM modules or RDIMM also isolate the command, address, and clock signals, which reduces system loading and allows a greater number of modules on a given system. RDIMM RAM also includes ECC error handling and correction, increasing data reliability using DDR SDRAM chips. 4GB DDR (1) ECC Registered memory modules are becoming scarce on the open market. These DDR 4gb ECC Registered were the first generation of ram to achieve the single "4 gb of memory" per single stick, in speeds of PC2100 DDR-266, PC2700 DDR-333 and more recently PC3200 DDR-400.
