asus MemOK!

[lorenzo.afw]

i am unsure on how exactly to use theMemok! button on my asus p8z68-v lx as the LED is not behaving as described in the manual. I have installed ram that is noted as compatible on the manufacturer website and the asus qualified vendors list however i cannot enter my OS. Please could you help me by tellng me in more detail how to use the Memok! button. The ram i have installe is: Crucial  4GB (2x2GB) PC3 - 10600,  CL=9, unbuffered, Non-ECC, DDR3 1333MHz, 1.5V or 1.35V (?), 256meg x 64MB.

Eh? You have the 2x2GB set and then a 256MB stick?

Your RAM is compatible with your motherboard; it should work fine... What I would do:

Try testing each stick of RAM in every single RAM slot and see if it boots.
Disconnect power from the PSU, wait for a minute or so and move the CMOS jumper into "reset" position, then move it back.

This is how the MemOK! button is supposed to work:
