Welcome to the Forums.
From page 26 of the HMM, the Z500 can take up to:
Standard Memory • DDR3-1600/1333MHz SODIMM × 2 (max 16 GB)
A 12GB (8GB+4GB) upgrade is also feasible but if the machine came with 4GB (2GBx2), I would go for an 8GB(4GBx2) or 16GB (8GBx2) depending on your needs and workload.

Thanks for ur reply...
but my machine comes with two slots 4GB and 2GB
I would prefer to go for 8GB and 4GB...Is there any performance issue for
(8GBx2) or 8GBx4GB) is more compatible to my device
Please suggest, then i can go ahead by updating this
There is nothing wrong with your scheme. You're right the performance will be affected since the memory modules now will be operating in single channel instead of dual channel. So to be sure of having optimum performance for your upgrade use 2 x 8 GB ram modules or 2 x 4 GB modules. Here is a very good video explaining about the advantage.
