I had originally ordered 3 of the Jdata DDR3 1333 ram (which actually cost much more)her on Overstoack. Installed them and I had one module bad right off the bat. Returned it and when I installed the replacement, one of the other modules failed.

call Kingston 4 help --they were very helpful -so I got the one !! thanks

Kingston's ValueRAM range rules the roost when it comes to no-frills budget memory, and the KVR1333D3N9K2/8G kit is a perfect example. For less than £80, you get a pair of 4GB modules of DDR3 RAM, rated at 1,333MHz.

Made from the highest quality components, ValueRAM ® memory modules for notebooks are designed to improve the reliability and performance laptops, collected by the users. Over time, increased speed and reliability allows to further increase efficiency in the overall decline in the cost of purchasing...

All good - received the wrong product the first time round though.

The three year old motherboard's manual stated that RAM sticks of 1, 2, or 4 GB size could be used. There was no mention (pro or con) of using 8 GB sticks (like these) in this motherboard, so I was a little nervous about trying these.

As with Kingston products, plug them in, and they work; I used two of these sticks, in order to increase the computer's RAM (from 6 GB to 16 GB) in a late model home-assembled computer that was being changed from XP Pro to Windows 7 64 bit Pro system

None at all
