BIOS
Some of the card's inner workings can be revealed by taking a look at the BIOS.
We used GPU-Z to extract the board's BIOS and Radeon
BIOS Editor to examine its contents.

Clock settings. Boot/3D setting in red, idle in green, UVD in yellow.

Clock speeds of 725/1000MHz in 3D, 157/300MHz idle, and 400/900MHz when UVD
is at work were confirmed using GPU-Z.

The stock fan's speed rises steeply, running at 22% until the core temperature
reaches 55°C and increasing linearly until 102°C when it reaches its
maximum speed.
MP3 SOUND RECORDINGS
These recordings were made with a high
resolution, lab quality, digital recording system inside SPCR's
own 11 dBA ambient anechoic chamber, then converted to LAME 128kbps
encoded MP3s. We've listened long and hard to ensure there is no audible degradation
from the original WAV files to these MP3s. They represent a quick snapshot of
what we heard during the review.
These recordings are intended to give you an idea of how the product sounds
in actual use — one meter is a reasonable typical distance between a computer
or computer component and your ear. The recording contains stretches of ambient
noise that you can use to judge the relative loudness of the subject. Be aware
that very quiet subjects may not be audible — if we couldn't hear it from
one meter, chances are we couldn't record it either!
The recording starts with 5~10 seconds of room ambiance, followed by 5~10 seconds
of the VGA test system without a video card installed, and then the actual product's
noise at various levels. For the most realistic results, set the volume
so that the starting ambient level is just barely audible, then don't change
the volume setting again.
