usual, I tested its overclockability in 2 aspects – AGP
bus-speed and Core/Mem clock settings. Firstly, I am pleased to report that the GeForce Pro
handled my overclocked 82.6MHz AGP bus-speed just fine, as
its SDRAM version. So
the switch to DDR has not affected its AGP resilience in
the card I received was extremely overclockable. I really couldn’t believe how high I could clock
this thing up to… Now
if only all cards could be this resilient!! Just check out
the table below and you’ll see what I mean…
about 1 second into Q3Demo benchmarking
Q3Demo*, but hung in D3D benchmarking
all Q3Demo and D3D benchmarks
after several seconds during Q3Demo benchmarking
Do note that Q3Demo used is the latest rev (i.e. Based on
Q3Test 1.09 build); Also 1 cycle means a complete range of
benchmarks for different resolutions and colour depths.
that I had to use Powerstrip to change the mem settings
beyond 330, as the Creative overclocking utility sets that
as its memory speed limit.
can testify that 145/355 exhibits good stability, having put
it through 4 to 5 hrs straight of continuous benchmarking
without lock-ups. This
includes running it through 3D Exerciser, the strenuous
Dagoth Moor Zoological Gardens benchmark, etc. It was strange that at a mem speed of 365, I managed
to run a complete set of Q3Demo OpenGL benchmarks just fine,
but D3D benchmarks would fail consistently. Nevertheless, it seems that 145/355 is the sweet spot
for my setup.
as a comparison, my previous SDRAM 3D Blaster GeForce could
only make it up to a 140 core stable setting.
Hence, as the GeForce chips are typically similar, I
was probably fortunate enough to receive a top of the line
retail sample. But
practically, I think one can generally expect a stable
setting ranging from 130 to 150 core speed for the Pro.
addition to the DDR memory overclocking experience during my
tests, I was also privileged to test yet another DDR GeForce
sample during a recent Sitex '99 computer exhibition at Creative’s
booth about 1-2 weeks back (held in Singapore, Suntec City). Then,
I also cranked the DDR mem setting all the way up to 330
(max allowable on the Creative overclocking utility
slide-bar and ran 15 mins worth of Q3Demo benchmarks without
any lockups). Hence,
I am confident that the Infineon DDR SGRAM can expectedly
achieve between 330 – 360 stable mem speeds.
Groovy! But how does that
translate to actual gaming performance!!??
