NX7800GTX-VT2D512E Geforce 7800GTX videocard is already one wickedly fast
piece of hardware, but PCSTATS would be remiss if we didn't attempt to overclock it now wouldn't we? Our experiences with GeForce 7800GTX 256MB models were bittersweet because the stock cooling solutions didn't really further the cause, so we're holing the cards close at hand this time around...
The GeForce 7800GTX core on the MSI NX7800GTX-VT2D512E is already clocked 120 MHz faster than 'stock', so head room is going to be tight. The core clock speed was increased in 2-3 MHz intervals until it passed the 600 MHz mark.
Good so far.
Continuing past 618 MHz proved to be totally futile. The MSI NX7800GTX-VT2D512E would start to throttle back, which was surprising since core temperatures apparently remained below 60 degrees Celsius.
Next up was the 512MB of GDDR3 memory which is clocked at 1700 MHz! Increasing that speed in 10 MHz intervals allowed us to move up a 100MHz pretty uneventfully. The GDDR3 craped out right at 1819 MHz though, with visual artifacts appearing if pushed a single megahertz further.
Considering how the previous GeForce 7800GTX 266MB videocards overclocked, it's refreshing to see the MSI NX7800GTX-VT2D512E do so well! End score: 618MHz GPU, 1819MHz memory.
