Unreal Tournament 2003 is the sequel to 1999's multiple 'Game of the Year' award winner. It uses the very latest Unreal Engine technology - where graphics, sound and game play are taken beyond the bleeding edge. Unreal Tournament 2003 employs the use of Vertex as well as Pixel Shaders and it's recommended that you use a DirectX 8 videocard to get the most out of the game.

The UT2003 overclocked numbers are closer than I thought they would be, since UT2003 likes its bandwidth. As usual, the OCZ PC4000 Gold Dual Channel VX performed on par with the other modules at stock speeds.

Overclocking does give a healthy performance increase to some of the individual time demos in UT2004, showing that extra memory bandwidth does have something to offer to gamers.

Doom 3	Source: id Software

Doom 3 is the most advanced game to date. it takes advantage of the latest videocard technology and pushes the processing power of the CPU to its absolute limit. At its highest setting, Ultra quality, texture sizes pass the 500MB mark which means even tomorrow's videocards will have a hard time running everything. The frame rates in the game itself are locked at 60 fps so anything above that point is wasted. Each test is run three times with the third run being recorded.

Doom 3 shows a very nice performance boost due to overclocking. When viewing this benchmark, please keep in mind that only the memory is running faster than it's supposed to and everything else is at stock speeds, including the CPU!

Maximum DDR Overclocking Tests

Conclusions on this VX-level DDR

In the world of high-end memory there are a lot of competitors for the crown and OCZ is near the top of that list. With OCZ producing memory like the PC4000 Gold Dual Channel VX, other enthusiast memory manufacturers have responded in turn. Now, you can find similar memory pretty much everywhere from everyone.

At stock speeds, the 512MB modules of OCZ PC4000 Gold Dual Channel VX performed on par with other PC3200 DDR DIMMs we've tested recently. You really can't complain about the performance of an AMD Athlon64 4000+ teamed up with a fast videocard and good memory.

Of course the OCZ PC4000 Gold Dual Channel VX's strong suit is overclocking, and boy did it kick butt. With 2-2-2-5 memory timings and a voltage of 3.5V, the memory hit an amazing 268 MHz! Loosening up the timings didn't allow us much better performance inspite of the increased speeds to 283MHz FSB.... but we also didn't try too hard since tight timings are so important for performance.

While the benchmark results were only moderately better, please keep in mind that everything else in the system was kept at pretty much stock speed. That additional 8 fps in Doom 3 and 1000MB/s bandwidth in SiSoft Sandra was all due to the excellent overclock from the memory.

With a retail price of $256 CDN ($204 US), the OCZ PC4000 Gold Dual Channel VX memory kit is an absolute steal (at least compared to what we're use to seeing for high-end memory). If you're an enthusiast itching to have the fastest system on the block, it's a pretty good bet that this set of OCZ can help you build a speed demon.
