Velocity Micro Raptor 64 DualX review: Velocity Micro Raptor 64 DualX

As a result of its high-end configuration, the Velocity Micro Raptor 64 DualX turned in some impressive numbers on our application and gaming performance tests. Its score of 188.1 frames per second (fps) on our Doom 3 1,024x768 tests was second only to that of the Falcon Mach V system, which scored a record-breaking 205.1fps. The Velocity system also placed second behind the Mach V on SysMark 2004, with its 289 trailing the Falcon's 306. The performance differences seem to be linked to the graphics driver software. The Velocity Micro came to us with Nvidia's 81.95 version of its GeForce drivers, the Falcon with the newer 81.97 version. Nvidia has since released its 81.98 drivers, which may boost either system even further. As always, we recommend you update your drivers regularly.

Now we come to the interesting part.

Given that the Velocity Micro Raptor 64 DualX and the Falcon Northwest Mach V are essentially the same system (with minor variations in clock speeds and hard drive configuration), we were surprised that the performance numbers were so different. We were also surprised that the Falcon PC crashed during our 1,600x1,200-resolution Doom 3 test.

Our investigation led us to simply play the game on each system, and to our surprise, neither system was able to play with 8X antialiasing turned on for more than 30 seconds before a complete system shutdown. We put it to both Velocity Micro and Falcon Northwest, and also to AMD and Nvidia, to help us find the cause. AMD replicated the problem and pinned it to the power supply.

To check AMD's theory, we pulled one of the GeForce cards out of each system and played Doom 3 again and found no instability, even with the antialiasing jacked to 16X. That indicates to us that the graphics cards were drawing more power on those high-detail settings than the 600-watt power supply in each system could handle (an EnerMax PSU in the Velocity Micro, a SilverStone in the Falcon Northwest). Velocity responded by sending the system back to us with a 1-kilowatt supply installed (it also added the $440 1kW supply to its online Raptor 64 DualX configurator during the course of this review). That cleared up the Velocity's crashing issues, even with the system overclocked. Falcon Northwest did a little digging of its own and came back to us with a report from SilverStone, noting it saw the same crashes, and that this was likely due to the distribution of power through out the system, rather than the total wattage.

By moving to the 1kW power supply, Velocity solves the issue with brute force. That's one way to do it. The other method is to dial down the antialiasing. Antialiasing set at 8X kills your gaming frame rate with little to no recognizable visual improvement, so that's not the biggest loss. The responsibility lies with both system makers to make sure their configurations work. Still, we're surprised that Nvidia's SLI Certification program didn't catch this issue ahead of time, since both of the power supplies in question are SLI-approved. We've been told that Nvidia and the power supply vendors are working on the issue, and we hope they resolve it soon.
