		| The GeForceFX 5900XT GPU has basically been equipped 
with some slower memory, and priced it at about half of what a regular 
GeForceFX 5900 goes for. 87% Rating:

MSI FX5900XT-VTD128 |  |  |  
 Overclocking ResultsMSI uses the "TOP Tech" cooling solution on the 
FX5900XT-VTD128 which is supposed to keep the NV35 GPU up to eight degrees 
cooler than the reference cooling solution, all the while producing just 26dB worth 
of noise. While cannot confirm temperatures, we did notice the card was 
nearly silent in the 3D benchmarks. The only 
way we could hear the videocard was if we put our ear right next to fan, and even 
then it was very faint. One thing I noticed was, the FX5900XT-VTD128 did not 
have native hardware monitoring within the Forceware 53.03 drivers, too bad it's 
a very handy feature. 
 Unlike the GeForceFX 5700 Ultra class videocards which 
use DDR2 memory, the FX5900XT-VTD128 uses more affordable Samsung DDR RAM 
modules (eight 128Mbit 2.8ns, marked K4D263238E-GC2A). The memory is actually 
the same as that found on most ATi Radeon 9600/9700/9800 based 
videocards. Those of 
you who use dual monitors will be happy to hear that there is a DVI to analog 
converter included in the FX5900XT-VTD128's package. We were a bit surprised to 
see that the S-Video and Composite cables were not included. MSI are usually 
very good at including all the necessities, and I'm sure this is just a one off. 
Their website says those cables should be 
included. Next the overclocking results! Overclocking the Card 
     When we first started 
to play with the MSI FX5900XT-VTD128 we found the core was clocked at 400 MHz, 
which is the same speed as the regular GeForceFX 5900!
 Starting 
at 400 MHz, I immediately increased the core speed to 450 MHz which is the 
default clock of the GeForceFX 5900 Ultra. Not surprisingly, the FX5900XT-VTD128 
had no problem with that. Next we pushed it to 475 MHz, or stock speed for the 
GeForceFX 5950 Ultra....  Again 
this little 
red card didn't have a problem hitting that mark, not bad at all! After we 
raised the core speed a few MHz at a time, we finally maxed it out at a very 
respectable speed of 504 MHz!  Memory 
Overclocking Next up 
was the memory. The memory was already clocked at its theoretical max speed 
(1000 MHz / 2.8ns x 2 =   714 MHz). I was pretty sure the memory would be 
good to 760-780 MHz, after all that's what most ATi Radeon 9700/9800 Pro memory 
mixes out at. Fortunately for us, the memory was up to our overclocking 
challenge. Starting 
at 700 MHz we slowly raised the memory frequency in 5 MHz intervals. Amazingly 
the card didn't let up, and we ended up hitting a nice high of 809 MHz! I think 
heat may have been limiting our overclocking as the Samsung DDR BGA memory was 
measured at approx 57 degrees Celsius with an Omega OS643E-LS Infrared digital 
thermometer.  I'm happy 
to say that both the core and memory played nicely together, and as you'll see 
in the upcoming benchmarks the FX5900XT-VTD128 running at 504 MHz and 809 MHz 
respectfully really does improve performance!

 |  |  benchmarks and 3dmark03 we've 
been a supporter of FutureMark since the days of 3DMark99, but for the time 
being we have stopped including 3DMark03 in Videocard benchmark suite. It has 
become clear that recent events have cast so much doubt in the legitimacy of 
3DMark03 results that it no longer serves much reference value to our readers. 
We are aware of FutureMark's Approved Drivers list, but they can be somewhat 
limiting if newer WHQL drivers are available on the web. If the situation 
changes we will re-evaluate our position, and reintroduce the benchmark as 
decided. If you have any questions or concerns, please contact us by e-mail or speak your mind in the 
PCstats forums.
