Overclocking the Shuttle XPC SG33G50 / BIOS

Overclocking Results:
Stock Max. OC
Motherboard Speed: 333 MHz

440 MHz

If you're new to Overclocking and not sure what to do, check out these two excellent Guides for some pointers:
Overclocking the CPU and Memory
Overclocking the Videocard

When it comes to overclocking, Intel is on the ball. Its P35 Express is the best overclocking chipset available and its upcoming X38 Express is slated to be even better. Even Intel's mainstream and entry level chipsets are kicking a lot of butt, so we have some high hopes for the Shuttle XPC SG33G50 and its G33 Express chipset.

The small form factor system will be equipped with an Intel Core 2 Duo E6750 processor and 2GB of Corsair's Twin2X2048-6400C4 memory.

The memory was first set to run at DDR2-667 MHz mode, but the CPU clock multiplier was left at 8x because there are no CPU clock multiplier options in the BIOS. Starting at 333 MHz FSB, the Shuttle XPC SG33G50 motherboard clock speed was overclocked in 5 MHz increments. The computer easily passed the 400 MHz mark without breaking a sweat, all current generation Intel motherboards hit that level easily.

At 420 MHz FSB the Shuttle XPC SG33G50 system started to show some signs of instability, so the Northbridge voltage was increased to 1.3V and CPU to 0.25V above stock. That solved our issues and we continued to push the PC further. The Shuttle XPC SG33G50 hit a maximum speed of 440 MHz FSB, and that was that.

Oh well. In any case, an overclock of 440 MHz still isn't too bad speed considering the Shuttle XPC SG33G50 is a SFF PC first and overclocking platform second.

Inside the Shuttle XPC BIOS:

The Shuttle XPC SG33G50 has the usual memory timing options we've become accustomed to; memory operating frequency, CAS Latency, RAS to CAS Delay, RAS Precharge, etc. It also allows you to adjust your onboard frame buffer - the larger you make that though the more memory the system memory it takes over. ;-)

The Shuttle XPC SG33G50 motherboard frequency can be increased to 600 MHz FSB. The maximum CPU voltage is 0.5V above stock, while DDR2 memory goes as high as 2.575V, FSB voltage to 1.35V, Northbridge to 1.4V and the Southbridge Set voltage to 1.65V and 1.2V respectively. The Shuttle XPC SG33G50 lacks CPU clock multiplier adjustments. Without those, you will not be able to overclock as high as with a full sized motherboard, but then again that is not be a big selling feature for this type of computer.
