nForce4 SLI Motherboards: Premium Performance at a Bargain Price

ASUS A8N-SLI Premium: Features
Asus has engineered a very effective cooling system that utilizes a small heat sink attached to a heat pipe that comes in direct contact with the nForce4-SLI chipset. This system then transfers the heat to a finned heat sink that also cools the MOSFETs. The whole system is fanless, but relies on the exhaust air generated by the CPU heat sink fan to cool the finned heat sink. We would recommend that a fan be placed on or near this heat sink when water or phase change cooling systems are utilized.
The Silicon Image 3114R SATA II RAID (red) ports are located to the left of the CK8-04 chipset and above the nForce4 SATA II ports. The SATA II ports feature the old attachment design that could create connection issues.
The nForce4 USB connectors, IEEE1394a connector, Com1 serial port, and System Panel connector are located along the left edge of the board. The CMOS reset is a traditional jumper design located between the battery and Super I/O chipset that proved to be inconvenient at times.
However, in between the two x16 PCI Express slots are the two PCI-E slots. This configuration could potentially render the PCI-E x1 slot useless when utilizing the first x16 PCI Express slot. The amount of space in-between the two PCI-E x16 slots is excellent and allows for a two-slot or third party video card cooling solution to be utilized. The first PCI slot next to the second PCI-E x16 slot will be rendered useless when utilizing a two-slot video card cooling solution.
The finned heat sink, which cools the MOSFETs and is part of the heat pipe system, is visible along with the 4-pin 12V molex connector next to the PCI-E x16 slot. The molex connector is required when utilizing two video cards in SLI operation.
Asus places the four-pin 12V auxiliary power connector at the top of the CPU socket area, but out of the way of most aftermarket cooling solutions.

Off to peruse your Intel articles.DAPUNISHER - Wednesday, January 4, 2006 - link
I enjoyed your review, your 1st for AT? but for a moment, I though I was reading a retro review from AT. I liked it better when AT eschewed 3D synthetics, and chose to bench the latest, greatest titles. Even D3 and FarCry seem long in the tooth IMHO. Many do still play FarCry, but most use all the new tweaks.Perhaps there is logic to the methodolgy that I'm missing? TIA for any illuminating reply, and I look forward to your future reviews here :-)

Hi,Actually, I have been covering the Intel reviews for the past few months. We are in the process of a transition over to the newer benchmarks. The last Intel article with those benchmarks can be found here-
http://www.anandtech.com/mb/showdoc.aspx?i=2631&am...">http://www.anandtech.com/mb/showdoc.aspx?i=2631&am...
The ability to go back and test all of the boards shown with the new benchmarks and driver sets was not possible. However, the next roundup should include newer benchmarks along with results from these three boards. Also, while FarCry and SC3 are "getting" long in the tooth they are both based on engines that can still stress a system by increasing the settings. They both offer a fairly good mix of cpu and gpu limited testing. The difference between D3 and Q4 is minimal except for SMP support now. We are also looking at providing repeatable and meaningful benchmarks for the RTS/SIM crowd without resorting to FRAPs. We plan on increasing the audio, power consumption, and disk RAID subject matter within the review process. You should see this process evolve over the next couple of months.

I got the original ASUS A8N-SLI Premium with a AMD X2 3800+ and found the stability very less than satisfactory with any bios less than 1007. However over clocking has been mediocre, at the standard multiplier (10X) I can raise the FSB to 254, from 200, providing a reasonable over clock, anything higher than this I seem to be hitting the wall. The voltage options are a real disappointment only letting me raze them to 1.45v. However I get no difference when overlooking when my voltage is 1.4 to 1.45, (except for my core temp), with the old bios I could raze the v-core to 1.5 and run the FSB at 260 very happily (the system did sometimes crash every 32 hours or so), I did not test it any further then before upgrading to 1007.When upgrading from the bios 1005 to 1007 I found that it would not post after the update, after much delay and many tests and try's I found that my very low timings T1-2-2-2-5-2 for the ram stopped it from booting. I gained control of it from putting in a stick of very old pc2100 ram and re-set the bios timings to automatic.
With your review I found it disappointing that you did not test the Silicone Ice raid controller, I have been wondering witch one I should run my hard drive on.

We will be including RAID results in future articles. There have been some issues with repeatable results utilizing a variety of benchmarks and of course drive configurations.
I would run the native nF4 RAID setup over the SI3114 in this case (assuming RAID0). However, if it were the SI3132 chipset on the board I would probably call it a toss up at this time.

Why would you bother to include a bunch of performance charts where the difference between the leading and the trailing boards is less than 5%?Don't you have enough important info to put in your articles instead of fillers?
Gary Key - Wednesday, January 4, 2006 - link
Thank you for the comments. I think the purpose of the article was to show that performance between a $100 board and that of boards costing up to $250 (A8N32) is basically the same at stock speeds. The differences in pricing will usually (not all of the time) buy additional features and greater performance via stable overclocking.
What would you like to see in our articles that we are not providing?

It may be worth noting that in the 1011.001 BIOS, the maximum vcore drops to 1.500V with dual core processors. :)Gary Key - Wednesday, January 4, 2006 - link
We did not have an opportunity to finalize testing with the dual cores for the articles but this issue has been brought to Asus's attention. Thanks!yacoub - Tuesday, January 3, 2006 - link
Wtf is up with the BlueGears card?? Is that simply a driver issue or not? It's such an excellent audio solution it's beyond shocking to see it perform even WORSE than onboard sound solutions when it comes to cpu usage. wtf indeed! Generally simply being a peripheral PCI device sound solution means it should be well BELOW the usage of onboard sound. Now I'm worried about purchasing their new card coming out this month (X-Plosion - onboard DTS in addition to onboard DDL like the X-Mystique has).Please update us when you receive the new drivers and figure out why the cpu usage of this card during gaming is so atrocious. Thanks.
