The Gigabyte 8N SLI Quad Royal is a member of the Royal product family and, as such, is a fully featured flagship board targeted for the PC gamer, enthusiast, or general office workstation user. The board will ship with an extensive accessory package along with several features such as C.I.A. 2 (CPU Intelligent Accelerator 2), M.I.B. 2 (Memory Intelligent Booster 2), EasyTune 5, and several board enhancements including upgraded components such as capacitors and power transistors.

The BIOS options are extensive on the 8N SLI Quad, with memory voltage to 2.4V, and a full 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 Optimal setting that will set the memory to the SPD settings. This Optimal setting will adjust the memory timing settings automatically when the system is overclocked. You have the ability to set the system clock mode to Optimal (sync the fsb and memory to their rated standard), Linked (sync the fsb and memory proportionally as you increase the front side bus), or Expert (allows independent adjustment of the fsb and memory).

The new revision of the nForce4 SLI 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 and 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.
