The Asus P5N32-SLI Deluxe is a member of the ALife product family and, as such, is a fully-featured flagship board targeted towards the PC gamer. The board ships with an extensive accessory package along with several dynamic overclocking features such as AI NOSTM (Non-delay dynamic Overclocking System), AI Overclocking (intelligent CPU frequency tuner with preset profiles), ASUS PEG Link (automatic performance tuning for single/dual graphics cards), ASUS CPU Lock Free (BIOS setting to unlock select multiplier locked CPUs), and the ASUS Ai Booster Utility Precision Tweaker software that allows control over certain system settings within Windows. The board also features the exclusive 8-Phase power design, Copper Heat Pipe technology for cooling the chipsets, Stack Cool 2 design to dissipate heat to the opposite side of the motherboard, and an external SATA II port on the back I/O panel.

The BIOS options are extensive on the P5N32-SLI Deluxe, with memory voltage to 2.4V, and an extensive range of chipset, bus, and vCore voltage adjustments. Memory ratios are handled like other nForce4 SLI Intel Edition boards in that the number of memory dividers is so numerous that you can simply enter a target memory clock and the BIOS will select the appropriate memory divider to produce a setting as near as possible to the requested value. The board fully supports manual memory timing adjustments or allows for an Auto setting that will set the memory to the SPD settings. This Auto setting will adjust the memory timing settings automatically when the system is overclocked. You have the ability to set the system clock mode to Auto (sync the fsb and memory to their rated standard), Linked (sync the fsb and memory proportionally as you increase the front side bus), or Manual (allows independent adjustment of the fsb and memory).

The new revision of the nForce4 SLI x16 Intel Edition Chipset fully supports all dual core Pentium D processors. We confirmed that the board worked properly at stock and over clocked settings with an Intel 820 processor and an 840 processor, and there were no problems with the board recognizing the two cores and four logical processors that are created with the Hyperthreading feature on the 840 EE processor.

    It is an awesome board.

    Thank you for the comments about the sound tests. We will be expanding this test suite greatly in the coming weeks. If you think BF2 has a hit, wait until you see the F.E.A.R. scores with sound effects at maximum. ;->
    However, in order to be consistent we will be testing the latest driver sets for each audio implementation along with adding an X-FI into the mix. The audio drivers within the latest NVIDIA 6.82 platform set are more game friendly than the RealTek versions but you give up some functionality and features for it.

    Gary - don't know if you will see this or not, but it would be interesting to see how the X-Fi series Creative card compares to the BlueGears X-Mystique, which is a highly rated ~$90 audio card available from NewEgg among other sites that has an excellent featureset (of course it lacks the latest EAX that Creative keeps for themselves so they have a reason to sell their wares to gamers, but it has more Dolby-related 5.1 features than the X-Fi series).

    Would be neat to see those two cards compared in "% usage" of CPU during gaming.

    Good Day,

    I have bought several cards the past few weeks including this one and the Chaintech AV-710. I intend to greatly expand the scope of audio testing on the board reviews due to the advances in on-board quality/drivers or the lack of in the nF4 area. I have a hard time understanding why most board manufacturers are shying away from C-Media as their on-board solutions always worked/sounded better than the RealTek AC97 counterparts. In the HD audio area it is a toss up in my opinion but I prefer the SigmaTel codec's on the Intel boards at this time including Intel's software packages. Hopefully I will be able to have the full audio section available in a couple of weeks. The next article series will have a little more information but is not representative of where we will be going in the future.

    I appreciate the comments and suggestions. I welcome anyone to email me if you have concerns or suggestions about our information. Obviously we have a format to adhere to and cannot test every possible hardware/software solution but I am always open to suggestions. :-)

    Oh and dual true-16x PCI-E slots and the passive cooling are both incredibly desireable features. When the AMD version of the board comes out I'll be all over it provided it reviews as well as this one did. Reply
  • Leper Messiah - Thursday, October 27, 2005 - link

    If the AMD version works as well as this one does for intel's, I've got my new mobo picked out. Heat pipe cooling+ 8 phase power= The win! 840EE's at 4.2 might actually give an overclocked X2 a run for its money! :gasp; Reply

    840EE's at 4.2
    Except that EE's will run MUCH hotter than X2's. This isn't a big deal if you have your own nuclear reactor.

    It was not that bad on this board (a very good description from you), idle temps at 37c, 4.1GHz at 46c according to the bios readings. I believe they were very close as I had a duplicate setup with the MSI P4N in it and you could feel the difference with your hands near the case. We will have thermal tests in the near future.
  • Karaktu - Thursday, October 27, 2005 - link

    One thing I would REALLY like to see added to review articles is the total power consumption of the test setup, both at stock and overclocked settings. There are a couple of power supplies (Coolermaster, Thermaltake) that include attached wattage displays for convenience.

    This would be useful for a number of reasons, not the least of which would be an idea of how much it's going to cost you to run such a rig. ;)

  • Gary Key - Thursday, October 27, 2005 - link

    Hi Joe,

    We have discussed this and it is nice to see a request for it. :-) Hopefully, once I have the test equipment setup then we can include these results in selected articles. You will find this information in the some of the CPU reviews already. We will also start checking thermal readings when a manufacturer introduces new technology onto the board. Asus did this with the eight-phase design and it certainly helped the thermal conditions on the board and with the CPU. This was based on a more subjective review of numbers generated from the bios and monitoring programs (along with overclocking results) which is okay for a high level discussion but is not detailed enough for absolute objective statements.

    Thank you.

    I find it very hard to believe that this is an 8 phase vreg. Simply counting the inductors indicates that it's only a 5 phase. Can you post the VR controller part number so I can see the datasheet?
