2. A Closer Look
The A8N32-SLI Deluxe, as with most of the latest ASUS Deluxe motherboards, is manufactured on a black Printed Circuit Board (PCB). The interface connections are laid out so as to make them easily accessible and the colour coding helps in identifying them.



Below is the 939 socket for the AMD64 CPU.

The STACK COOL 2 logo located on the underside of the board, indicates that the A8N32-SLI Deluxe has a fan-less, zero-noise cooling solution, providing effective heat transfer away from critical components.





The A8N32-SLI Deluxe, is equipped with two PCI Express x16 slots, used primarily for nVidia graphics cards, and three PCI slots. The two PCI Express x16 slots are colour coded. In SLI mode, the user should always remember that the primary graphics card must be installed in the blue PCI-E slot. The secondary card (black slot), is used only for graphics acceleration. Both slots remain at 16X even in SLI mode.

The memory module slots are also colour coded. Simply install two memory modules of the same memory size in the same coloured slots, to enable Dual Channel's symmetry mode support, or use two memory modules of different memory sizes for asymmetric mode.

The primary IDE connector is located on the edge of the board.

Below are the four SATA connectors for installing HDDs or CD/DVDs.

This connector is for a Serial ATA signal cable. It supports a Serial ATA HDD drive that you can combine with an external Serial ATA 3 Gb/s device to configure a RAID 0 or RAID 1 set through the onboard Silicon Image SATA RAID controller.

There are also additional USB and Firewire IEEE 1394 connections on the motherboard:


There are also some extra connectors for the serial COM or GAME/MIDI ports.

4. 3DMark2005
With 3DMark05, Futuremark continues the tradition in its benchmarking software by providing a state-of-the-art Microsoft ® DirectX ® 9 3D performance benchmark.
3DMark05 is an all new 3DMark version making the most of Microsoft's DirectX
9. The previous version 3DMark03, did a nice introduction into this level
of technology. However
3DMark03 used DirectX 9 specific features in a limited manner, because fully
supporting hardware was rare at the time of its launch. In contrast, 3DMark05
requires DirectX 9 hardware with full support for at least Shader Model 2,
and takes shader usage to never before seen levels.
Just like its predecessors, 3DMark05's point system is set so that at the
moment of release, the high-end VGA cards available in stores can only score
around 5000 3DMarks, whereas the worst card that meets the programs requirements
yields a score of 1000.
Game Test 1 -Return to Proxycon
Being the sequel to the "Battle of Proxycon"
from 3DMark03, in "Return to Proxycon" we're once again set in space
and the battle continues as space pirates invade a cargo ship in order to
take control of its valuable cargo.
This test, tries to simulate a future first-person shooter game with all the high details that entails. The dynamic shadows, high-detailed environment and advanced lighting techniques ensure that under normal circumstances, no recent card can run it with decent frame rates.
Game Test 2 - Firefly Forest
A forest gets filled with magic fireflies in the night. The moon is nearly full, illuminating the forest with a bluish faint light. The magic fireflies have flickering bright green lights that playfully move around the forest.
This scene is a nice example of a smaller scale outdoor scene with rich vegetation. Immediate visibility is not so far, and there is a skybox surrounding the whole scene.
A large number of trees with their branches swinging separately, and dense vegetation being dynamically distributed according to the camera movements, make this test the most demanding of the three.
Game Test 3 - Canyon Flight
A Jules Verne type airship flies through a canyon guarded
by a dangerous sea monster. The airmen defend their ship using heavy cannons,
but these seem to have no effect on the huge sea monster. Finally the crew
manages a narrow escape using the "last resort" afterburners of
the airship.
This scene is fairly complex with large areas of water
reflecting the high canyon walls. The water actually is one of the key points
of interest in this scene. The water not only does realistic looking reflections
and refractions, it has a depth fog, making the sea monster swimming under
the airship actually look deep down in the water. The air in this scene also
uses a volumetric fog, making distant cliffs of the canyon really look far
away.

In GT1 and GT2, the Asus A8N32 motherboard reports lower framerates than the ABIT, while in GT3 it produced higher framerate.
Final Score
3DMarks on 3DMark05 are now calculated by the following formula:
(Game Test 1 * Game Test 2 * Game Test 3)^0.33 * 250
This is basically the geometric mean of the total frames in each
game multiplied by 250. This means that all game tests are now equal.

A slightly better 3DMark05 score is achieved by the ABIT AN8 32X in comparison to the ASUS A8N32 SLI Deluxe motherboard.
5. 3DMark2003
3D Mark is a widely used and accepted benchmark that stresses the DirectX performance of a VGA card. A very strong point of 3DMark is that it's VGA card measuring is does not require any CPU power. So the resulting fps are a good reference a VGA card's rendering performance. For testing the performance of each card we used the 4 game benchmarks 3DMark has.
3Dmark03 also includes sound and CPU tests as well as some other feature tests.
- Game Test 1 - Wings of Fury (DX7)

This test is a combat flight simulator written for older hardware (DirectX 7). Particles are used a lot in this test - smoke and vapor trails, flak and gunfire, and explosions are produced using point sprites and quads.
- Game Test 2 - Battle of Proxycon (DX8)

This test is a simulation of first person shooter game types. 1.1 and 1.4 Vertex shaders are widely used since all character models are skinned using vertex shaders.This makes this test a good vertex shader comparison for VGA cards.
- Game Test 3 - Trolls' Lair (DX8)

This test should be the favorite of all RPG lovers. It is a cut scene of a female warrior facing two malicious trolls. Again the same vertex and pixel processing is used as in game test 2.
This test also uses post-processing effects, such as Depth of Field and Bloom effects which are widely used in today's game cut scene sequences.
- Game Test 4 - Mother Nature (DX9)

Mother nature represents the level of effects and realism that are possible using 2.0 vertex and pixel shaders, plus some other features that DirectX 9 offers.

Once again, no significant differences were reported between the two mobos. However, the framerates were generally higher with the ABIT.
- 3DMark Official score
If you test your machine with 3DMark, you can post the results at 3DMark's online result browser. For more information visit futuremark.com.

And again, higher score from the ABIT motherboard, with the ASUS close behind.
6. Codecreatures
CodeCreatures is a synthetic 3D benchmark that is a good reference for VGA performance comparison. This is a high-end 3D benchmark that also requires DirectX 8 hardware, making a good tool for measuring the potential of DirectX 8 game performance.
The Codecreatures benchmark is written with Microsoft's DirectX 8.1 API and incorporates the use of Vertex and PixelShaders popular on next generation 3D accelerators.

The benchmark plays a photo-realistic nature scene and calculates the performance of the graphics adapter by measuring the fps that it can display at 1024x768, 1280x1024 and 1600x1200 resolutions.

Similar framerates from both the A8N32 SLI and AN8 32X motherboards in the CodeCreatures benchmark.
-Codecreatures number
The codecreatures number is the resulting score of the total
benchmarking process and is basically the geometric mean of the three frame
rates multiplied by 100.

Higher overall score for the ABIT motherboard.
7. Aquamark - 3DMark01
Since the majority of today's applications and games are compatible with DirectX 9, the need of benchmark applications that use DX 9 has been brought up. The benchmark uses the 3D engine (Krass engine) of the Aquanox game.
Aquamark Triscore
The Aquamark Triscore comprises 3 values: the overall system performance, the performance of the graphics system and the CPU performance. Keep in mind that this is not the total result of the tests, but the result of the whole benchmark process including all 9 chapters.

The ABIT 32X once again reported better results.
3DMark 2001
3DMark 2001 is the predecessor to 3DMark03. It's mainly a directx8.1 benchmark and the score depends a lot on the CPU power of your computer. However for reference use only we decided it'd be best to just leave it in our benchmark list so you can compare the next generation cards with the possibly outdated you have at home.

And again, ABIT has a higher overall score.
8. Half Life 2
Half life 2 is without doubt the most anticipated PC game of all times.
Characters - Advanced facial animation system delivers the most sophisticated in-game characters ever seen. With 40 distinct facial "muscles," human characters convey the full array of human emotion, and respond to the player with fluidity and intelligence.
Physics - From pebbles to water to 2-ton trucks respond as expected, as they obey the laws of mass, friction, gravity, and buoyancy.
Graphics
- Source's shader-based renderer, like the one used at Pixar to create movies
such as Toy Story® and Monster's, Inc.®, creates the most beautiful
and realistic environments ever seen in a video game.
AI - Neither friends nor enemies charge blindly into the fray. They can assess threats, navigate tricky terrain, and fashion weapons from whatever is at hand.
To measure performance, we used the Video Stress Test (VST) that is available in the CounterStrike:Source beta available through Steam. We set all the details to the highest level and each time changed the resolution from 800x600 up to 1600x1200.


The Half Life 2 Video Stress Test confirms the results we saw in the foregoing benchmarks. Here, in all cases, with or without the AA and AF, the ABIT motherboard produced higher framerates.
9. Quake 4
In a desperate war for Earth's survival, against an unrelenting alien enemy, the only way to defeat them is to become one of them. Armed with advanced weaponry and vehicles and aided by an elite squad of marines, you take the battle to the heart of the Strogg home planet and become Earth's only hope for victory.
Quake 4 is a First Person Shooter developed by Ravensoft, based on the Doom 3 engine, and the graphics and gameplay certainly reflect that fact. For those who really hated the one-way corridors of Doom 3, new outdoor areas have been added to the game. The feeling however, still remains the same as these areas are quite small-scale, contrary to what other games have to offer.
- Benchmark Settings

As Quake 4 includes no default benchmark, we decided to go with another publicly available demo to measure performance. What we chose is a demo from HWSpirit, which involves a small outdoor scene followed by a long indoor combat. As preloading the stage once again failed miserably and the average framerate varied a lot, we ran it twice every time we restarted the game and measured only the second run.

The resolutions we used are 800x600, 1024x768, 1280x1024 and 1600x1200. We measured performance with and without Anti-aliasing.


In Quake4, the differences between the mobos aren't significant with AA and AF enabled. However, when we disabled AA and AF, the ABIT motherboard produced noticeably higher framerates than the ASUS.

10. F.E.A.R.
You aren't a soldier. You are a weapon. A paramilitary force infiltrates a multi billion dollar aerospace compound taking hostages, but issuing no demands.
The government responds by sending in its best special operations teams, only to have them obliterated. Live footage of the massacre is cut short by an unexpected wave of destruction that leaves military leaders stunned and in disbelief.
First Encounter Assault Recon (F.E.A.R.) is one of the new-generation FPS. The graphics are really stunning, the plot behind the whole shooting successfully keeps it interesting and even the A.I. seems to work out well.
F.E.A.R. offers a lot to the First Person Shooter world. The graphics are very clear with excellent textures, great new effects that will stress your graphics card and ragdoll physics that are waiting to be exploited as you progress through the game.
- Benchmark Settings
F.E.A.R. allows you test the video settings on a mini-benchmark involving a lot of weapon firing, explosions and several other effects. After the benchmark is run, you're presented with a screen showing your minimum, average and maximum framerates and also percentages of how often the framerate was below 25fps, between 25 and 40, and finally above 40. For this presentation, we're just sticking to the minimum and average framerates.

The resolutions we used were 800x600, 1024x768, 1280x960 and 1600x1200. We measured performance at high and highest details.



With High Settings in F.E.A.R., the ASUS motherboard performed better than its ABIT counterpart, producing higher average and minimum fps, except for 800x600 resolution.



With the Maximum settings enabled, the ASUS motherboards clears up its position, producing significantly higher minimum and average fps.

11. Need For Speed - Most Wanted
Wake up to the smell of burnt asphalt as the thrill of illicit street racing permeates the air.
Combining illicit street racing and tuner customization with the intensity of strategic police pursuit that surpasses any Hollywood-style chase scene, Need for Speed Most Wanted will be on every gamer's 'must-have' list this holiday season. Out-race rivals, evade cops and exploit hundreds of miles of open road as gamers make their way up the Blacklist.
To become the most wanted racer, players must build up their street cred and Rap Sheet with gripping, white knuckle, head-to-head races with the top drivers on the streets, as well as pull daring, evasive moves to out-run and out-fox the cops that patrol the open road. Players can manage their heat or utilize a number of strategic tactics to keep the cops off their tails as they leave their rivals behind to suck their exhaust fumes.

- Benchmark Settings
NFS Most Wanted includes no default benchmark. To measure the card's performance, we've chosen to record the framerate at the start of a circuit race with end-game cars. The starting point tends to be one of the most graphically demanding parts because of the smoke coming from spinning wheels added to the rest of the game's visual effects. If a card can pass this step with an acceptable framerate it is guaranteed that it will face no problem with the rest of the game.

The resolutions we used are 800x600, 1024x768, 1280x1024 and 1600x1200. We measured performance at the lowest and highest possible settings.


The ABIT motherboard once again takes the lead, but the differences between the two is not significant.

12. Performance Test v5.0
The suite of the PassMark Performance Test contains a number of suites with different tests to measure different aspects of a computer system.
The "PassMark rating" is a weighted average of all the other test results and gives a single overall indication of the computers performance. The bigger the number, the faster the computer. The "PassMark rating" can only be calculated if the results from all other tests are available. The value is calculated as follows.

According to the PassMark Performance test, the ABIT AN8 32X motherboard is a better overall performer than the ASUS A8N32.
13. PCMark04 - 05
PCMark04 and 05 are application-based benchmarks and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark05 to be a smaller installation as well as to report very accurate results. As far as possible, PCMark05 uses public domain applications whose source code can be freely examined by any user.

Both PCMark04 and PCMark05 include 5 categorized suites for benchmarking your computer. These include System, CPU, Graphics, Memory and a Hard Disk Drive benchmark. In our case, we selected the system test suite which integrates tests included in the other categories.


Both PC Mark04 and 05 awarded a higher score to the ABIT AN8 32X motherboard. The same PC components seem to perform better on this NForce4 SLI 16X based motherboard.
14. Overclocking
You can increase your Asus A8N32-SLI Deluxe motherboard's system performance with the AiBooster utility, bundled in the software package. The default FSB for the AMD64 3500+ is 2200Mhz.


The maximum overclocking speed we managed to achieve was 2700MHz with the FSB running at 299MHz. We tried this both with AiBooster and through the BIOS. At higher speeds, we saw the blue screen of death, or the system failed to boot.

Utilities



ASUS Update is a very helpful utility which helps locate the appropriate firmware revision for the motherboard and then flashes it automatically.

We highly recommend that you download the new BIOS manually from the internet first, and then proceed with the flash procedure.
18. PC Probe II
We highly recommend you install this software. It will provide you with helpful information about your system.
ASUS has upgraded its PC Probe utility, providing a more impressive layout.

If something isn't within specs or isn't working properly, the right panel lights up red.


Voltage, temperatures and fan speeds are some of the parameters you can monitor.





You can also monitor the HD and RAM conditions as well as CPU Usage.



19. AiBooster
AIBooster is a convenient utility to help overclock your system. There is no need to delve into the BIOS with this utility, although we believe that the BIOS is still the safest way to go.

You can select from pre-defined overclocking profiles, the same as those available in the BIOS.

Or you can manually adjust the settings by changing the CPU or Memory Voltage as well as the FSB speed.

After any changes, you'll have to restart your system. You'll be informed with the appropriate message.

20. Conclusion
The A8N32-SLI Deluxe is certainly going to be on most gamers list of preferred motherboards. Dual X16 PCI-Express SLI support, high games performance and a full retail package with all required cables, manuals, drivers, applications and extra fans make this a very attractive package. Taking a closer look at the the black colored PCB, you will notice that it is of quality construction, incorporating the Stack Cool 2 technology for transferring generated heat away from critical components. The board is also equipped with dual Gigabit LAN, HD-AUDIO, SATA RAID, Dual Channel, N.O.S., which are just some from the long list of features for this motherboard. The only thing that is missing is on-board WiFi and IDE RAID.

When we compared the performance of the A8N32-SLI Deluxe against the ABIT AN8 32X, we saw slightly better performance from the ABIT. In games for example, the difference between the two was in most case no more than a few frames, while in most of the benchmarks, the ABIT motherboard was consistently awarded higher overall scores. Nevertheless, the difference between them isn't significant.
At the time of this review, the A8N32-SLI Deluxe cost US$197 from newegg.com, placing it among the more expensive boards. However, we think it is worth every last cent.
Pros:
- Dual X16 SLI support
- Good Retail Package
- Very Good performance
- Quiet operation
- Monitor utility from within Windows
- Q-Fan and AI NOS features
- Excellent overclocking capabilities
Cons:
Like to be fixed
- A lower price would be welcome
