Re: RAM Compatiability

hi bhupeshjawade,


As per this pdf data sheet, the Lenovo Z580 can accommodate up to:


8GB max; PC3-12800 1600MHz DDR3*, non-parity,
dual-channel capable, two 204-pin SO-DIMM sockets


Depending on your processor, the 1600Mhz speed may downclock if the memory controller on the CPU only supports a lower clock speed (i.e. If you have a i3-2370M CPU and you use a 4GB DDR3 1600Mhz RAM,  it will downclock to 1333Mhz)


For the brand, you can use Crucial, Kingston, Patriot, GSkill, or Corsair.

Re: RAM Compatiability

I recently bought Z580.  (I5, 6 GB RAM and 1TB harddisk)


It should be having two DIMM slots as per the specifications. But i am not able to two slots in BIOS when i checked.


I could only see total physical memory as 6GB in BIOS. If it has two slots, it should show wht RAM installed in which slot.  correct ??? Please advise here.


Please confirm it it has two slots available. Because, i need upgrade it to 8GB.

Hi suffice,


I don't have a Z580 to check physically, but the on-line BIOS simulator only shows total memory, not individual slots.


6GB of RAM in your machine implies two slots with 4GB and 2GB sticks installed.  You can double-check your specific model in the ipbook:


Instructions on locating and replacing RAM are in the Hardware Maintenance Manual:
