Overclock with ASUS P5N32-SLI Deluxe Motherboard

The new revision of the nForce4 SLI x16 Intel Edition Chipset fully supports all dual core Pentium D processors. 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.

The Asus P5N32-SLI Deluxe 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 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).
