Memory Question

[zoliky]

Hi,
I have an EP35-DS3L - the maximum supported memory for this motherboard is 8GB DDR2.
I have 2x2GB Memory - KINGMAX KLDE88F-B8KU5.

I would like to buy another pair 2x2GB but the model is different. Something like: KLDE88-B8KB2
Is this a problem for OS X?

For example:
Memory Slot 1 (yellow): KLDE88F-B8KU5
Memory Slot 2 (yellow): KLDE88F-B8KU5

Memory Slot 1 (red): KLDE88F-B8KB2
Memory Slot 2 (red): KLDE88F-B8KB2

Please help me! I would be grateful for any answer!
