This is two 512MB sticks of DDR 400MHZ CL2 I dont know if this is compatible with macs. The memory has two LED displays that go on top of the RAM sticks. The software that comes with them is for PC only. The software you can put custom words etc.. on the RAM LED Displays. I had this installed in my pc the only reason that I am selling it is because I upgraded to more amount of RAM. 100 dollars for these. Shipping shouldnt cost much since this is a lightweight item.
Thanks,
Chris
