Memory upgrade for z580

I have ideapad z580 with 4GB memory. I have used cpu-z to collect the info about the memory and it shows DRAM frequency as 798,3 MHz. I have no idea what is the actual speed of the memory. Is it 800MHz?? I am planning to buy another 4GB memory. Want to know what frequency module and which brand to buy so as to avoid comapatibilty issues???

Re: Memory upgrade for z580

hi satyr,

 

Welcome to Lenovo Community Forums!

 

If you're using CPUZ under the SPD tab it may say 800 Mhz for your RAM

and Given that it is a Double Data Rate the Reading of CPUZ should be Multiplied by 2

so the Actual Speed your RAM has is 1600 Mhz. 

 

This link may give you info about certain Configuration and maximum offered components by Lenovo

Techincally it's 1600MT/s mr. Support Specialist.
DDR3-1600, PC3-12800    800 MHz   1600 MT/s

Re: Memory upgrade for z580

You can buy DDR3-1600 sticks. If you have 1x4GB installed you can buy another 4GB one for a total of 8GB memory, or another 8GB for 12GB of memory. You can even buy 2x8GB sticks for a total of 16GB of RAM. You probably won't need that much.

Remember to buy DDR3-1600 (different name DDR3-PC12800, but this is the same thing). There is also DDR3L, but this is NOT the right one for your computer.

Refer to this:
