Memory
performance
A
well known thorn in VIA’s side is the poor memory
performance of the 133A (& earlier) chipsets. As it turns
out it seems that a lot of this can now be attributed to
unoptimized settings for memory.
This
first shot is from my system with the BIOS setting for memory
set to By SPD & with System/SDRAM
frequency ratio set to 1/1 (SDRAM runs at the same
bus speed as the system is, in this case 100Mhz).
As
you can see, memory performance is pretty damned good compared
to what it used to be in VIA based motherboards, e.g. below is
a shot from my Abit VT6X4 using the same default settings.
Next,
I tweaked memory settings as recommended in 3D
Alpha’s VIA 133A memory tweaking guide. Here’s the
memory benchmarks run with SiSoft Sandra once these new
settings were applied.
Overall
memory performance is quite excellent with this motherboard,
only lagging behind BX memory bandwidth by less than 10% -
& that’s with using the default memory settings
for the P3V4X.
CPU
& Multimedia benchmarks
Below
are the results of the CPU & Multimedia benchmarks offered
by SiSoft Sandra.
The
results are slightly (10% or so) behind that of the Intel PIII
500, although seeing as I’m running on a PIII 450 these
results seem accurate. Nothing bad, nor interesting to note
about these results really – They are about right for a
Pentium 3 450.
