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.

    Why would ANYONE spend the coin to buy an Intel based SLI system when you can buy an AMD system for the same price that will out-perform the Intel system and be upgradable for years???

    The only reason I can see for anyone buying any Intel product at this time is if they are stuck with an Intel system already and they desire to upgrade to a faster chip if they can find one to fit whatever socket Mobo they have. Otherwise I see no logical reason whatsoever for even considering an obsolete, under-performing Intel product.

    You ask the wrong question. Why would anyone buy a SLI/CrossFire system at all. Reply

    You ask the wrong question.
    He can ask any question he wants. There are no wrong questions.

    Because one can. :)

    I only afraid on the future upgradeability on this board because according to ASUS Support FAQ (as this news has not been revealed on the Internet), this board does not support future Pentium 4 that based on 65nm technology, namely Cedar Mill (Single core replacing Prescott) and Presler (Dual core replacing Smithfield)

    So how is testing done the Presler sample processor cause I thought Anand got holding of 1 Presler sample...Pls double check at the following :">

    As Presler start hitting OEM already....we need more info on this issue???

    As Presler start hitting OEM already....we need more info on this issue???

    The initial information I have from Asus this weekend is the board will support the 65nm CPU range with a bios update and the CPU steppings must be B1 or above.
  • Gary Key - Thursday, October 27, 2005 - link


    I had already asked for public clarification about this issue from Asus after visiting the website last week. I believe the entire FAQ has not been properly updated as it still states the Pentium 820 will only work in single core mode which is no longer the case with this chipset revision. We have not had an issue testing the Presler or Cedar Mill CPUs with current board designs from different suppliers.

    I will respond once I have further information.

    Thank you.

    How's the clearance on the right-most PCIe x1 slot? It looks like a card put in there would be perilously close to the northbridge heatsink. Reply
  • Gary Key - Thursday, October 27, 2005 - link


    The D-Link DGE-560T PCIe network adaptor card fit fine and it is the longest card I tried in the x1 slot. I would agree if a card had several logic chips placed in the right area on the back of the board then clearance could be an issue with the heatsink. However, the few peripheral PCIe cards that I have fit fine.

    I wouldn't have minded seeing the difference between bridged SLI and bridgeless SLI on both SLI Dual x16 and SLI Dual x8 motherboards.

    My gut feeling is that nVidia is going to be phasing out the bridge in the near future, if they can get the same performance without it using the PCIe bus.

    "ASUS CPU Lock Free (BIOS setting to unlock multiplier locked CPUs)"

    Does this mean that all multipliers (up and down) are available again?
