Memory Upgrade Question...Mix Matching?

[skylinegtrv98]

I have recently completed my first build, and everything is going well, but I was thinking about picking up another 2gb of memory for my system... here are my specs...

GIGABYTE GA-MA78GM-S2H AM2+/AM2 AMD 780G HDMI Micro ATX AMD Motherboard - Retail

AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor Model ADX6000CZBOX - Retail

A-DATA 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model ADQVE1A16K - Retail

I bought that ram because I was able to get a good combo deal when purchasing from the egg....anyways I know my board can support DDR2 1066 ram, and I was wondering if it would be worth it to get a second set of 2 gb DDR2 1066 ram to make a total of 4gb, or if I would be able to run it like that, or would I have to stick with the DDR2 800...Oh and I am running Vista 32bit so I know that I am limited to a total of 4gb right...Thanks in advance

All four sticks have to run at the same speed. Therefore, there is no point in purchasing DDR2 1066 since it will run at 800.
