The MSI NX8800GTX-T2D768E-HD videocard
is pretty darn quick in its own right, without anyone messing around with
it. That doesn't mean PCSTATS is going to spare this flagship videocard from
the overclocking tests.
We'll be starting today's overclocking tests
with the nVidia 'G80' GPU first. It is clocked at a default speed
of 576 MHz, and that frequency will be increased in 5 MHz increments.
Using RivaTuner, the GeForce 8800GTX core turned out to
be a pretty good overclocker and easily cracked 600 MHz. Shortly thereafter
we passed 610, 620 and 630 MHz without any trouble. nVIDIA may not want
videocard manufacturers to factory overclock the G80, but that doesn't mean it
doesn't overclock well!
The MSI NX8800GTX-T2D768E-HD hit a top speed of 665 MHz
before RivaTuner stared to complain about it not passing the internal test. If
we disabled the internal test, the core could probably go higher but with stock
cooling, I didn't want to push too hard. There are reports online that the
G80 scales well with watercooling, TEC or phase change cooling solutions.... but
unfortunately none of those types of cooling were available at the time of this
Next up was the 768MB of Samsung GDDR3 memory.
This videocard memory is clocked at 1800 MHz by default, or 1.8GHz.
We were a bit more aggressive when it came to overclocking the videocard's memory,
and took it in 20 MHz strides.
past we have seen Samsung GDDR3 memory overclock well this way, so we were
anticipating some really fast results this time.
The MSI NX8800GTX-T2D768E-HD's memory didn't disappoint.
We broke through 1900 MHz in no time, and closed in on 2000MHz just as fast. The
2 GHz plateau came and went, as did the 2100 MHz barrier!
A few moments later, we reached the end of the game,
with the memory at its maximum speed of 2132 MHz. RivaTuner started to complain
about failing the internal driver test, so we didn't try for anything
One of the interesting results of all of this
overclocking was that it didn't actually improve the benchmark results of the
MSI NX8800GTX-T2D768E-HD videocard all around... However, as you saw from the
power draw tests, overclocking does have a noticeable impact on total system
Aside from reaching for 3DMark records the
NX8800GTX-T2D768E-HD is fast enough for hardcore gamers at its stock speeds,
even those of you who play 1600x1200+ with AA/AF. It's hard to believe, but
overclocking really isn't all that necessary with this GPU.
The details of how the MSI NX8800GTX-T2D768E-HD test
system was configured for benchmarking; the specific hardware, software drivers,
operating system and benchmark versions are indicated below. In the second
column are the general specs for the reference platforms this nVIDIA GeForce
8800GTX based videocard is to be compared against. Please take a moment to look
