Basic Features: Asus A8N32-SLI Deluxe
Yes, this is an Asus board, and not a DFI or Abit. The feature set and adjustments are extremely broad compared to any board. The names of the options are sometimes a little different and the adjustment ranges are often set up differently, but everything that an enthusiast needs to get the most from the Asus A8N32-SLI is here.
This Asus provides memory voltage all the way to 3.2V, among the best that we have ever seen from a tier 1 board maker. This should be an adequate range for any memory on the market other than the disappearing VX and Redline high-voltage modules from OCZ and Mushkin. While nothing on the market really comes close to the DFI memory voltage range to 4V, adjustments to 3.2V are more than adequate for current 2 GB modules and any other current DDR RAM.
Memory adjustments are the broadest that we have seen on an Asus board. The ranges are not always as extensive as a DFI or ATI Reference board, but the assortment of control options is just as wide as you will find on any production board.
We know of no other current AMD motherboard with HTT adjustments to 1600. However, don't get too excited by this. We quickly found that the HTT settings above 1000 don't work and the board freezes when they are selected. When we asked Asus about these expanded settings, they told us that they were included for a future enhancement of the AMD on-processor memory controller, which may or may not happen based on the latest information that they have received. The settings above 1000 don't work with current processors, even with the E6 memory controller.
CAS 1.5 is an option in the BIOS, but Asus tells us that it is really a feature for extracting the best performance from DDR333 memory. Sure enough, we couldn't get it to work with DDR400. However, it worked fine with DDR400 memory at DDR333 - providing an interesting option for extreme overclocking.

The Techreport writes about overclocking with AMD Cool'n'Quiet here:They highlight two important bios options:
and with regards to memory overclocking:
Does this board have these options in bios?
As Techreport writes:
I must say I agree.

Can we get some official info on these questions?They're high on my list of features. I was all set to go with the DFI until I saw this review. These features may win me over if the ASUS has them too.

It looks like official reply is not going to happen. does anyone know if the Asus A8N SLI;Delux;Premium has this in later bios? If so I would bet this one has it aswell.Capt Caveman - Monday, November 7, 2005 - link
The latest bios for the Asus A8N-Sli Premium came out yesterday and no, it does not have this feature so I doubt the A8N32-Sli Deluxe will have this feature. Not very many overclocker's use CNQ, so I don't think there's a huge demand for this feature unfortunately.WobbleWobble - Friday, November 4, 2005 - link
I wonder if it's better than the DFI because of the PEG mode Asus implements on its motherboards, which overclocks the videocard.Wesley Fink - Friday, November 4, 2005 - link
And I disabled "PEG link" mode for our review. Asus has settings in PEG for Auto, Normal, Fast, Faster, and Disabled. We set "Disabled" because we know this trick. Asus suggests using "Faster" for review tests. On the positive side you have that additional performance waiting to be tapped.We also turn off the overclocks that are enabled when many boards arrive for review. That's the first thing we check.

Really nice to see such diligence!Capt Caveman - Friday, November 4, 2005 - link

Also, if you're running SLI with 2 dual-slot video cards, where are you supposed to put a sound card, or any PCI card? It seems like the only slot available will be, if it's possible at all, the one above the 2nd video card. Not sure how anyone's gonna be able to use any PCI card with SLI.
