From the Asus support site.

If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as:

- System BIOS (including motherboard, add-on cards, etc..)
- Motherboards resources
- Memory mapped I/O
- configuration for AGP/PCI-Ex/PCI
- Other memory allocations for PCI devices

Different onboard devices and different add-on cards (devices) will result of different total memory size.
e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses.

On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices.

This limitation applies to most chipsets & Microsoft Windows 32-bit version operating systems.

If you install Windows 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met: 1. The memory controller which supports memory swap functionality is used. Chipsets later than Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture support memory swap function. 2. Windows 64-bit OS which can address more than 4GB memory.

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.
http://support.asus.com/download/download.aspx?modelname=A8N-SLI%20Premium&SLanguage=en-us
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:

Your memory should be in slots A-1 & B-1
You Asus board uses the Award bios. The link posted below will tell you what your beeps are saying.

In your case do as I suggested above. I have two working
A8N-SLI Deluxe boards & the memory works fine in A-1 & B-1 slots.

Good luck & best wishes!

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.
