For warranty service, the receipt or a copy of your invoice marked with the 
date of purchase is required. By calling your vendor or going to our RMA 
website (http://www.asrock.com/support/index.asp?cat=RMA) you may 
obtain a Returned Merchandise Authorization (RMA) number.
The RMA number should be displayed on the outside of the shipping 
carton which is mailed prepaid or hand-carried when you return the 
motherboard to the manufacturer. Shipping and handling charges will be 
applied for all orders that must be mailed when service is complete.

This warranty does not cover damages incurred in shipping or from failure 
due to alteration, misuse, abuse or improper maintenance of products.

Contact your distributor first for any product related problems during the 
warranty period.
