Fine DDR2 modules, no problem here
on February 17, 2012
My set works great, passes Memtest86+ test, no problem.
As this is 240-pin DDR2 SDRAM memory, chances are, you are buying it for an older computer. If this computer runs a 32-bit operating system, it is very likely the operating system can only use up to 4 GB of memory total, - though some, such as Enterprise editions of Windows Server with Physical Address Extension (PAE) can use more. As such, you may want to just completely replace memory sticks in the computer with these, instead of installing them in addition to the old ones.
The paragraph above does not apply to 64-bit operating systems; those can use heaps more memory.
These memory modules are PC2-6400 (utilizing DDR2-800 chips). You can use them instead of slower modules no problem.
For example, if your computer needs PC2-5300/5400 (DDR2-667), PC2-4200/4300 (DDR2-533), or PC2-3200 (DDR2-400) you can use these instead, just fine.
The Voltage is standard for DDR2, 1.8V. It is with newer DDR3 you have to worry about different voltages; not with these.
Note that these are non-ECC, non-registered, and non-buffered modules, meant for desktop computers. If you are buying memory for a server or a Xeon workstation, check if it calls for ECC memory, then these will not work.
Also, these will not work in most notebooks. And do not try to put them in computers that need even older DDR or newer DDR3 memory.
