Corsair 8000ul question

[mkbr]

Hello!!! I have a pair of corsair 8000ul(512x2) and I want to add more 1gb. Can I use a pair of corsair 8500? The timmings are different, but the fsb is equal, or i must have to use another pair of 8000ul? I glad your support.
Thanks

Yes, you can use just about anything. The system will automatically run *all* memory at the speed of the slowest installed module.
