240 Pin DDR3 PC3-10600 1333MHz
 

Hi,

I want to upgrade my RAM for my Acer Aspire desktop M3400. Accoring to the Mr.Memory website, I need:
240 Pin DDR3 PC3-10600 1333MHz x 4

Just before I actually buy some RAM, I would love to know if I have any other options?

For example another site has 240 Pin DDR3 PC3-10664 1333MHz modules. So are they better?

Or does anyone recommend something like this:

I dont know the difference and if they are compatible or not.

Hi abourke

Acer Aspire M3400 Desktop Computer
PC3-10666 DDR3-1333 240pin SDRAM DIMM RAM
Min 1GB
Max 8GB (4x banks of 2GB modules)

Advice (where possible)
.fill the module banks as pairs with modules of the same specification
(and if possible manufacturer)
.using mixed modules (1GB/2GB) across the modules should work ok;
but the order of the size of the modules across the banks may impact
system performance.

General advice
.Branded memory modules (though generally more expensive than unbranded (generic) memory modules) are tested to meet a specification for both suitability and longevity. In other words, the manufacturer is standing behind their product based on a published product specification.
.Generic modules, other other hand, can represent very good value for money, but
may be manufactured to a lower (but working) specification. Sometimes the actual module manufacturer is unknown because the modules are manufactured and branded for a client company for resale, and hence their actual specification and reliability for a particular purpose are largely unknown, other than they will "generically" work to the basic specification. The modules are designed to work across a range of motherboards based on the basic memory timing requirements
.Check the computer manufacturer's: documentation, specifications, www site for any information about restrictions/complications associated with memory upgrades
.Check the specifications for the modules to ensure that they match the system
.Try and buy multiple modules at the same time branded by the same manufacturer
.beware of the warranty terms

***if in any doubt, contact a PC shop that you trust to perform the works; if you encounter problems, then you can take it up with them

If you want to test the memory installed in a system, I suggest that you download a copy of MemTest86 from the 'net

Hope that assists
