Within the BIOS of the Shuttle XPC SD11G5 there are a
decent number of memory adjustment options, and onboard video configurations.
Memory specific options include CAS latency, RAS to CAS, RAS precharge and
memory frequency.
Users can also adjust onboard video features,
choose between onboard or PCI Express videocards (but not at the same time),
memory size and video out mode (digital or analog).
In the Frequency Control section the FSB can
be adjusted between 133-165 MHz, in 1 MHz increments. There are no other
features for overclocking. Under the PC Health Status portion of the BIOS, users
can select between smart fan, noise
control-ultra, noise control-low, noise control-mid, or noise control-full. We
recommend leaving it at the default setting; 'smart fan.'

experts tip: bios settings and noise levels |
|
if you know where to look on the shuttle.com website you can find an
acoustic test report for the xpc sd11g5 small form factor pc. because the
fan settings within the bios use general terminology to describe quiet vs.
ultra quiet options, it's hard to know what level of noise to expect with
each option. Here's the breakdown in Decibels as it relates to each choice
under the 'Advanced CPU Fan Setting' tab:
- Smart Fan: 24.5 dBA
- Noise Control-Ultra: 23.5 dBA
- Noise Control-Low: 23.9 dBA
- Noise Control-Mid: 29.4 dBA
- Noise Control-Full: 43.8 dBA
The acoustic test procedure
Shuttle applied measures noise levels from a 50cm distance away from the
XPC SD11G5 according to ISO 7779 standards. |

Bearing in mind that the Shuttle XPC SD11G5 is engineered for quiet
operation, the BIOS options that anyone interested in overclocking would need
are rather limited.
The only way to overclock the XPC SD11G5 is to increase the motherboard FSB
up from a stock speed of 133 MHz (the FSB is 133 MHz, the bus speed of the
processor is 533 MHz). The Intel Pentium M 740 processor has a default clock
speed of 1.73 GHz and it uses a 13x multiplier. There are no voltage options in
the BIOS, so overclocking the Pentium M 740 and Shuttle XPC SD11G5 will be a
little challenging.
Starting at 133 MHz, the FSB was increased in 2-3 MHz intervals all the way
up to 155 MHz before stability began to be an issue... And that was as far we
were able to overclock. Pentium M processors can overclock in certain situations
very well, but that is really not the point of the Shuttle XPc SD11G5.
The Shuttle XPC SD11G5 and its Pentium M 740 takes on desktop motherboards
equipped with the Pentium D 840 next... Can a mobile chip take the heat?
