Asus A8N SLI RAID showing both drives as "degraded"

Windows bootet normally after i chose normal mode, but the message in BIOS still displays and every time i reboot, windows asks again which mode to boot. (as if i had not shut down properly)

Re: Asus A8N SLI RAID showing both drives as "degraded"

This problem usually occurs if: 1) The computer never finished booting 2) A sticky button on you keyboard (F8 or Control Key for win98) 3) Less Memory for windows xp and ME. Try checking if all the memories as well fixed on the board and are being read. 4) Corrupt system files. 5) Incorrect bios configuration (Try changing the bios settings to optimum performance of fail safe to confirm that. All the best.

Problem adding Additional Ram to my Asus A8N SLI DELUXE system

Just because BIOS is recognizing the RAM doesn't necessarily mean it is usable. Also, ASUS recommends that you have the same amount of RAM in each bank. Another point they make is that your motherboard does not support double-sided DIMM chips.

I would refer to the manual for their specific instructions on proper RAM configuration:

If you are concerned that the memory stick might be bad, swap it out with one of your older ones, and see if your system boots and performs as it should. If not, then you know it is bad. My guess is that if you populate the memory slots with 4 gb, the system will recognize and make all of it available to you.

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.

What causes ASUS A8N SLI Deluxe chipset fan and RAID failure

Don't bother with another ASUS chipset fan...
just get hold of a Zalman ZM-NB47J Northbridge Cooler. :thumbsup:

i've been running one of these for a month or so because my chipset fan started to rattle, and make more noise than usual crying2.gif

i haven't had any trouble with passive cooling, maximum motherboard temp is 39C.
i run all my drives on the nvidia controller, and it's overclocked a bit too.

plus you'll enjoy the silence :thumbsup:
