How to over come all the problems associated with this motherboard?I have the latest bio and still the ps2 keyboard port does not work, the onboard backpanel usb do not work,i mean the usb provides elecricity to the externl harddrive but than the computer says error installing device.while the front ports work well when the same hardrive connected .using win xp pro sp2 x64

Are all the drivers installed?
Is there any yellow exclamation mark in device mgr?

yes all the drivers are installed

Clear cmos, load bios defaults, make sure USB is enabled.

i tried all of that still doesnt work , do u think reloading or repairing the os might help?

and dude i wanted to ask what is the meaning of dimm per channel i am not sure what speed ram to buy for this motherboard i want 8 gb but can u guide me with the speed please thanks

Yup, format & do a clean install of os.

The board is s*** hot.

There are 4 memory slots. They can be all installed for up to 8GB. Speeds must be 1066 or slower. My guess is there is some limitation to memory config. i.e. With 4 slots filled, the speed will be 800mhz to be prime stable.

Or click QVL download on that page. This list is the ram tested to be ok with the board by ASUS. You'll be guarranteed that the ram will work in this board.

thanks for answering dude since u are a genius at this work i want to ask you one more question.how do u know at what speed is the hyper terminal working i mean i have a phenom 9850 pro and u know the mother bord so please tell me how to speed up or even view hyper terminal .i have istalled sisoft sandra

Don't know what you mean by that. I think you meant to say Hypertransport (HTT) which is the same as FSB for Intel.

200Mhz HTT x 12.5 multiplier = 2.5Ghz



To overclock Phenom, up the HTT/FSB frequency from 200 to anything. Most would up this by 30mhz and do memtest (google) until it fails memtest, then they would back down to previous setting. Other settings may have to be changed. i.e. cpu, nb & hypertransport (HTT) voltage.



It's very time consuming. The Phenom overclockers prefer AMD Overdrive for Windows that lets you overclock the pc in Windows. You can do the same as above by changing the parameters. It can lock up. I think you can get up to 300mhz overclock out of your setup.

Use orthosx2 to stress test your overclocks. 8 hours would be considered stable. If it crashes or freezes up, back down your overclock or up the voltages a notch.

I don't have all the answers to o/c'ing Phenom. It takes time. You have to try it out yourself. If you need more help on this:
