Well i ordered this http://www.newegg.com/Product/Product.aspx?Item=N82E16820227267 as hyperx were out of stock. These have the same timings as my current ones (so it'll be mixed). And if it doesnt work as swingman says i'll just use 4 gigs (using only 2 slots) instead of current 2 gigs.
Thanks for the help. Here is my board btw, http://www.newegg.com/Product/Product.aspx?Item=N82E16813131225R ,asus p5k-e . Had no problems so far, except it takes about 15 seconds to start actually booting (posting) after you press the power button. It just sits there for 15 seconds without posting anything.
