will these two sticks work together?

[ElementBilly]

I currently have 6g of ddr3 1333 ram from Samsung at 9/9/9/24 in triple channel. My brother recently upgraded his ram and gave me two 1g sticks that mach exactly with my ram as they both came from our old alienware systems. The only 1g 1333 ram stick I can find that matches up close is at 7/7/7/24 at1.65v. Will these two sticks work together?
