Are These Two Rams Compatible With Each Other?

I am trying to make an old lenovo r500 laptop to be usefull at least for surfing the net which has a 2GB ram stick in it called Ramaxel 2GB 2rx8 pc3-8500s-777 HF. So i assume those 777 numbering is for its Cl value. The closest ram i can buy right now to pair with it is a Hynix 2GB 2rx8 pc3-8500s-7-10-F2. So can these two be paired without a problem or i need the exact same ram to go for?

It should work as long as they run at the same speeds/timings, but I wouldn't recommend it. You would be better to just get a new kit with 2x 2gb sticks. Also I found this on the website: 

Quote
Memory
  • PC3-8500 1066MHz DDR3, non-parity, dual-channel capable
  • Two 204-pin SO-DIMM sockets;
    • The use of 1066 MHz SO DIMM memory is recommended for this system.
  • 1GB or 2GB standard memory
  • Supports maximum memory up to 4GB
  • Recommended for memory expansion are 1 GB, and 2 GB PC3-8500 DDR3 1066MHz SO DIMM
  • Intel Turbo Memory 2GB
    Note: Only 64-bit operating systems support more than 3GB of system memory (RAM).

They should work together if the timings are compatible. What are the chips itself have printed on both of these sodimms? Do both have the same timings on your laptop?

Ramaxel is in my laptop and 'elpida' written on the chips. Other one is appearently hynix chips.  

 

''They should work together if the timings are compatible'' Yes what i am asking is this.

Does your laptop allow to alter the timings?

 

You do NOT plan on buying 2gb sodimm, don't you?
