Try replacing the CMOS battery.  There is no telling how long this new mobo was sitting on the shelf before you got it.  Usually a bad checksum error can be fixed by replacing the battery.

Clear CMOS and replace battery as noted above. Battery is a CR2032.

What CPU is installed? Is it compatible with motherboard and BIOS revision?

Problem could be a faulty BIOS as well. Provided CPU is compatible and if clearing CMOS/changing battery do not work, next step is to flash BIOS.

Replaced the battery, went to bios and change the clock and date settings.  Rebooted now it says CMOS Checksum Bad/Over-Clocking Failed!!!/Press F1 to Run SETUP.

Press F1 to enter the BIOS, reset the BIOS settings to default, and save & exit.  That should remove the problem.

The CMOS Checksum Bad Error is an error that occurs when the CMOS values are incorrect. Usually to guard your Bios software, your CMOS memory stores a specific value, each time you boot up your computer this value which is a number is checked against the stored value in the CMOS memory. If these two values are different, it causes an error message. If these values are the same, the computer proceeds as normal.

Each computer usually deals with the CMOS Checksum Bad Error differently. Some computers will warn the end user and continue to boot up using settings in the CMOS, other computers might warn the end user and then use the default settings in the BIOS as the correct settings and carry on with a normal boot or reboot. Usually, within the error message it will state which strategy your computer has employed.

There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:

1 - CMOS Battery not functioning properly
2 - Your BIOS has been updated (either by you or possibly a virus)
3 - The computer was shut down improperly (e.g. shutting off the computer's power without first shutting down the computer (MS Windows requires you to shut down your computer before shutting off the power).

A faulty BIOS. Try flashing BIOS.

Copy of code in BIOS does not match saved checksum value when BIOS code is loaded into memory on bootup -- hence error.
