The Cell Menu is the key page for all of the performance tweaks
for the chipset, CPU and memory. If your CPU is unlocked, as would
be the case with AMD's Black Edition chips, you can edit the ratio.
The manual doesn't make mention of it, but with the BIOS we've
flashed on to the board during the test process, there is now
an option to enable the TLB fix we mentioned earlier.

MSI's D.O.T.3 has 3 steps to overclock the CPU and
PCIE. Depending on CPU load, the system will dynamically overclock
itself. The settings are not terribly aggressive, thus keeping
the system stable, but you can still manually overclock or use
AMD's Overdrive utility. The Overdrive tool included on the Vista
driver CD did not work with our system and we had to download
a newer one, but the XP version MSI includes works fine.

The Advanced DRAM Configuration page allows the user to make
memory adjustments which will vary depending on the quality of
the memory being used. By default, the timings are set to automatic,
but setting them to manual will allow the various options shown
above.

The User Settings page is quite handy for those
of you who like to live on the edge. When overclocking, nothing
is really more frustrating than having to redo all your BIOS settings
whenever the CMOS is reset. You can store profiles here and after
a BIOS reset, you can reload your settings by coming to this page,
provided you save some valid settings. You'll still need to configure
the time and date, but everything else will load according to
your last save.
Test Setup
The MSI K9A2 Platinum AMD 790FX Motherboard will
be equipped with an AMD X2 5000+ for legacy testing, as well as
the AMD Phenom 9600 Black. A Seagate Barracuda 1TB will handle
the storage duties and a GeForce 8800GTX running ForceWare Release
169 for our video needs. Windows Vista Ultimate is the OS of choice,
fully patched up to the time of testing. 2 x 1024MB of Corsair's
DDR2 Dominator was set to 800MHz, configured in Dual Channel mode
for testing.
The comparison motherboards will be a MSI's AMD
690G based board and Foxconn's Nvidia 590 SLI based board. Both
boards were equipped with the same hardware, though limited to
the X2 5000+. All processors were ran at stock speed.
The software used is as follows:
PiFast
- A
good indicator of CPU/Motherboard performance is PiFast
version 4.2, by Xavier Gourdon. We used a computation of 10000000
digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory.
Note that lower scores are better, and times are in seconds.
CDex
Audio Conversion Wav to MP3 - CDex v170b2 was used
to convert a 440.5MB Wav file to a 320kbs MP3. Times
are in minutes:seconds, and lower is better.
TMPGEnc
2.54 - We used an Animatrix file, titled The
Second Renaissance Part 1, and a WAV created from VirtualDub.
The movie was then converted it into a DVD compliant MPEG-2 file
with a bitrate of 5000. Times are in minutes:seconds, and lower
is better.
DVD
Shrink - We ripped the War of the Worlds bonus feature off
the disk at 100% and compressed the file from the hard drive to
70%. Times are in minutes:seconds, and lower is better.
Photoshop
CS2 Driver Heaven Test - Photoshop is perhaps the defacto
standard when it comes to photo editing tools. Given that it is
so popular, we incorporated DriverHeaven's latest test into our
review process. Lower scores are better, and times are in seconds.
Enemy Territory: Quake Wars @ 640x480 and Crysis
@ 800x600 at LQ Settings - While higher resolutions tax the
video card, lower resolutions rely on CPU and subsystem speed.
Higher scores are better. We used Guru3D's Crysis benchmark tool
and the Checkpoint
timedemo for ETQW.
All benchmarks will be run a total of three times with the average
scores being displayed. Any system tweaks and ram timings were
configured to the best possible for each platform. Despite the
slight differences between the motherboards, we matched the tweaks
as close as possible. The drivers otherwise were identical.
PiFast

The 790FX board surpasses the 690G by a slight margin
and is barely edged out by the 590 SLI.
CDeX

The MSI K9A2 is the fastest board here by a couple
seconds using the X2 5000+. It's even faster than the 9600 Black.
