DDR3 Memory Compatibility Question

[jeffyboy]

I have asked this question around and keep getting conflicting answers. I need to try to find some compatible memory for the sticks I already have. I am currently running G.Skill Model F3-10666CL9D-4GBPK on a ASUS M4A78T-E Motherboard with a AMD PH II X4 965 CPU. Since that memory type (F3-10666CL9D-4GBPK) is no longer available what would you suggest I can use to add an additional 4GB (for 8GB total)?

Would the F3-10666CL9D-4GBNQ work even though the voltage is 1.5v where the 4GBPK is 1.65v?

Yes, you can try the NQ sticks. If it is not compatible, we can swap your PK for new NQ sticks.

Thank you

Thanks but for the cost I went ahead and bought some new modules (F3-12800CL9D-4GBRL)
