    Slots 2&4 is a good idea to try. However bear in mind that if you ever intend to buy more RAM, you could encounter the same problems again.

    With the keyboard problem... is it a USB or PS2 keyboard? Do you have a PS2 one you could try to see if that will work? I have had a similar issue in the past with my old system (totally different brand of board etc). Sometimes the keyboard would not allow me to enter the BIOS or navigate the boot menue. After a successful boot and then powering off, the keyboard would then work fine. This happened intermittently until I scrapped the USB keyboard and bought a PS2 one.


    ****EDIT****

    There's no danger using 2&4, you will be fine in that regard.
    The keyboard problem is what I first encountered on a bare bones start-up (RAM, Video card, keyboard, monitor). It would work...and then stop working. That's when I cleared CMOS...cleared CMOS again...and flashed the BIOS. Keyboard had been working fine since I moved the RAM and tweaked the BIOS (per many helpful suggestions on this board and another).

    Thanks!

    Default Problem solved!!

    Hi all,

    I just want everybody to know that with the help of this forum and motherboards.org, I fixed this. It was a bad memory controller. RAM slots 1&3 would not work. However, RAM slots 2&4 did, and I was able to achieve a stable system with Windows XP.

    However, having a bad memory controller kind of made me a little nervous, so...I RMA'd the board to Newegg. I got a new board within 10 days, and hooked it up. I still had to do all the BIOS adjustments that were suggested here, but the RAM passed memtest in slots 1&3, and everything is working fine.

    I am off to build my new system...and Intel Core i5 with the Gigabyte GA-P55-UD3R board. Yeah!!!

    Thanks everybody for helping me on this.

    Hello,

    I have a GA-EP45-UD3P motherboard and have similar problems! It starts up fine, but when I go into any menu option (meaning the keyboard worked fine to get to the menu choices), the USB keyboard and mouse no longer work. I.e., I try to change boot order so I boot from CDROM first, but can not use arrow keys. Or, I try to change my boot option (I have 2 hard drives, 1 with Vista and 1 with Windows 7), but can not change the selection.

    Any ideas? I have an Antek 650W power supply, 8 GB (2GB) each of DDR memory.

    Thanks in advance.

    Have you loaded optimized defaults, do that first if you have not yet.
    Do you have a PS/2 keyboard you can use or a USB to PS/2 converter?
    USB Keyboard/Mouse support in BIOS Advanced Settings may need to be enabled for a USB keyboard to work.

    Hello all,

    I called Gigabyte tech support (great tech support) and I needed to hit del key to go into Bios Setup and select "Integrated pPeripherals" and enable the USB keyboard. By default the option was disabled. After that all was fine.
