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.

    I just wanted to say that I REALLY appreciate the wonderful combination of a person who is a very, very good writer and technologist. This extremely rare combination makes him one of the best technical writers I've come across in the past 20 years.

    It's not too hard to find people who are technically competent but very hard to find someone who can communicate well and knows what the hell they're talking about (ask anyone who has been to college). Quite frankly, he sets a standard that I think all AnandTech writers (ok... all technical writers) should strive to eventually achieve. This level of expertise typically takes years of practice to acquire even among the talented. Can't wait for his next article.

    To quote the first post..."Mixing philosophy, classical literature and computer hardware reviews? Gotta love it."

    I greatly appreciate the comments. This was my third article and hopefully I improve with each one although you have now placed a great deal of pressure on me. ;->
    The next article series will be a multiple board review. I am learning how to convey several different messages in a very condensed form. It will be different than this last article so I would appreciate comments, good or bad. I try my best to listen to the readers and follow up on suggestions.
    I have two very good editors in Wes and Karen so it really is a team effort at AnandTech. I still have a great deal to learn and in fact will be taking a composition course this winter to improve my skills.
  • Kensei - Thursday, November 03, 2005 - link

    You are welcome. I don't think you need a composition course so I'd be interested in hearing how much you learned once it's over. Hopefully I'm wrong, but you may be disappointed by the course. If this is a college course, you may find that people in English departments don't quite get technical writing. It's different (although not totally different) than writing good short stories.

    Keep up the good work and I look forward to your future articles.

    So let me get this straight... In "theory" i can run my 820 at a 250fsb or 4.0, with a ddr700 rating?? And the board will recognize both the cores?? I'm tempted to get this board, but after having the previous one from ASUS, i'm scared to death, it was a HORRIBLE overclocker, max i could get was 230fsb, and lousey mem performance.... But if you say this board is different, i may try one.... Reply

    Email me please and I can forward some testing results to you along with additional information. Reply

    Please check your USB/Firewire/Ethernet throughput graphs for their use of MB (MegaByte) vs Mb (Megabit).

    Nice board :)

    I have corrected the charts. Thank you for noticing the issue. Sometimes you view something so much that you miss the obvious. :) Reply

    I read that you thought most would fit - "an excellent amount of room for alternative cooling solutions". Im wondering more specifically if the Scythe Ninja will fit with/without the optional fans. BTW did you test them, the fans? Wondering how much noise they make and if they work well. Reply
  • Gary Key - Friday, October 28, 2005 - link

    I do not have the Ninja although I know where to get one for a test. :) I received the optional fans a couple of days ago from Asus (tried to get them before publishing but it did not work out). I will try them this weekend and respond to your questions. They are designed to be used with watercooling or phase change setups. The stock Intel 840EE cooler (upgraded from other Pentium D units) provided enough air flow in the area to keep the MOFSETs cool. The aftermarket coolers I used provided more than enough air flow and fit great within the CPU area. Let me know if you need a listing of these heatsinks. Reply

    That's a freakin' awesome (if expensive) board!

    Btw THANK YOU THANK YOU THANK YOU for finally showing just how greatly sound enabled impacts the framerates on boards with on-board audio. Amazing that 17-19% of your CPU's power can be sapped by a stupid audio chip, especially when that turns into ~15fps drop in some games. Ugh.
