using DDR2 800mhz and DDR2 667mhz will give same performance in gaming

[jason29]

Hi, i have 2 GB 1 stick of transcend DDR2 800 and 1 stick of dynate which is 1 GB DDR2 667. I wanted to ask that if i use both ram, will it give me more performance in gaming, windows stuff, for future long run as 3 GB ram will run at 667mhz speed rather 800mhz Or it is better to use only 2 GB stick of transcend as it is 800 mhz.
Also will it affect that 1 ram is transcend and other is dyante, as dynate is consider bad as compare to transcend so mixing up them is bad idea?

Thanks

I think that placing a 1GB DDR2 667 with a 2GB DDR2 800 one won't give you a performance boost in gaming/apps. But getting a 2GB DDR2 800 will give you a performance boost (not much though since many apps/games run fine with 4GB). And as you already know that if you place the DDR2 800 with DDR2 667 then it will be backward compatible which wont output much.
