choice of RAM

[yrocka]

Help! I decided to increase the RAM on my computer from 4 GB to 8GB. I bought two DDR 3 memory  to 4GB 1333 MHz does not work. Bought 2 by 4GB 1066 MHz does not work ...

Tell me what kind of RAM is suitable for my device?
Before that, there were two DDR 3 memory units, 2 GB 1333 MHz each, and everything worked.

Crucial says the following RAM at lower voltage (cooler) should work on your machine

You need 2 pieces.

Thank you for the information provided, but it didn't help me! I saw this specification and was guided by it when choosing a new RAM. I tried PC3-8500, PC3-10600, PC3-12800 with 1.5V, none of them worked. I tried the specified memory from different manufacturers, it did not help. Voltage memory 1.35 did not try as it is not specified in the specification of my equipment. Now I have a memory of 2 x 2 GB with a voltage of 1.5 and everything works, but I want 2 x 4 GB. what can you tell me about this?

Hello! today I tried the memory that Crucial recommends, it doesn't work either! Please clarify the possible reasons and recommend RAM for purchase!
