I know this sounds like a stupid question, but I am still an "amateur" on compatibility issues and have a lot to learn in general. I am building a new computer (on signature and profile) and I have DDR2 533 PC2 4200 Ram and was wondering if it was compatible with the ASUS M2NPV-VM nForce 430 Motherboard (http://www.newegg.com/Product/Product.asp?Item=N82E16813131014). Also note that I got the open box version for $39.99 or something close to that, and it had no reviews at the time). Although I have noticed that some people have had some memory issues with the mobo (as well as cpu issues too). It should be at my house by tomorrow (Newegg is FAST!).
