Usb 2.0 problem

Hello. I have some problems with my ASUS A8N-SLI Premium... If I turn off USB2.0 Support on the BIOS, pendrives and external hard disks work well but in low speed. But if I turn on USB2.0 Support, then my Windows XP with SP2 don't recognize them. I need some help! Thank you!

Re: usb 2.0 problem

The cd that came with the A8N Sli Premium motherboard does not contains USB 2.0 Driver but instead has a note saying that the drivers are in Windows Service Pack 2

Re: usb 2.0 problem

If you do turn off USB 2.0, you may have two options, "Full Speed" and "HiSpeed". Make sure you use "Full Speed", as it's faster than "HiSpeed". But the real answer is that you need to install the USB driver for your motherboard. If it came with a CD, insert the CD and read the instructions on installing drivers from it; otherwise, check Asus's website under the Support/Downloads section.

ASUS A8N-SLI memory issues

imondeau, do you still have you're manual for the ASUS A8N-SLI Premium? Please turn to page 2-12 & 2-13.
Need the manual? Click the link below & download it.
The QVL; Qualified Venders List, shows all the tested memory for this board. Edge memory is not supported. This is why the Edge memory only runs by it's self. Once you add the corsair memory they clash because they are not compatible working together in this Asus board. Both sets of memory could work in another board. (Maybe)! What is also needed is if the corsair & edge DIMMs are SS = Single sided or DS = Double sided. How many chips on the corsair? How many chips on the Edge?
They must have the same total chips each each DIMM.

Edge does not sell memory compatible for the
Asus A8N-SLI Premium.
See this for you're self. Click on this link:

Asus A8N sli Premium - sli problems

I went through your bios manual three times & did not come across a setting that gives you the option as you listed above.
What I did come across & triple checked your Manual Pg. 2-28 section 14. Asus EZ selector card connector (144-pin SLI_CON.
When using two PCIE SLI cards make sure the card is seated correctly & set for Dual Video Cards. (extreamly important).
Pg. 4-34, section 4.4.9 SLI mode Recommend kepping to Auto. Than the Bios detects the setting of theSLI selector card.
Refering to the sentance above the manual recommends all settings be set to Auto. Your Bios will do the rest. If for unknown reason you no longer have your manual you can download it from Asus. You'll need to fill in the 3 windows under, Please Select the Product.
