GamePC heeft een review neer gemikt van de standaard Guillemot 3D Prophet met Single Data Rate SDRAM op 120/166MHz. De reviewer nam de moeite om wat heen en weer te pielen met de core en memory clock van de kaart en kwam tot een bevredigende 150/200MHz:
Just for fun, we decided to test how overclocking friendly the GeForce actually is. TNT-2 based boards were pretty much the least overclocking friendly out of the 3rd generation boards (overclocking as in the AGP bus, not the actual core and memory speeds). You couldn't really push your system's front side bus speed over 112 MHz without your TNT2 locking up, whereas 3Dfx products could last up to 140 MHz without a hitch. Good news is, the GeForce is much, much more stable with higher bus speeds and higher AGP clocks. With our 600B testbed, we were able to push the front side bus to a blazing 150 MHz, which in turn shoves the AGP clock to 100 MHz (1/3 over it's intended speed), and we experienced no problems. While we would have loved to tried further, the BE6 only allows up to 150 MHz FSB, and our PC-133 SDRAM couldn't likely handle much more.
On to core and memory overclocking, which was quite successful with Guillemot's Xentor card. We can gladly say, the tradition goes on with the Prophet. In our Pentium III 600B testbed, we were able to up the speeds from 120/166 core/memory to a nicer 145/190, without any extra cooling! During each clock speed 5 MHz markup, we ran a Quake3 Demo loop and 3DMark 99 Max to ensure reliability. At 150/195, the card simply gave up, than we decided to give it a little wakeup call by slapping our good friend The Card Cooler on it. With the extra cooling, we were able to clock it up to 150/200 core/memory, at completely stable levels. After 150/205, the card gave us visual artifacts and crashed quite often. Still, a 30 MHz clock speed jump is nothing to scoff at, it even raised our Quake3 HQ benchmarks up a nice 13 FPS. Of course, every board is different and your results may vary.
