I ran several runs of Unreal Tournament 2003 and tallied up the results. Is it really a surprise that the XtremeDDR shows amazing performance increases?

Using [H]ard|ocp's benchmarking script for UT2K3 I ran a series of benchmarks at the CPU setting. The CPU Test will allow the variation in system performance show without any help from the video card. With that said... there seems to be a 10FPS gap between the top scores of the TwinMOS and the XtremeDDR

Another popular tool for benchmarking is Return to Castle Wolfenstein. I did the same here, all tests are run at 640x480 (fastest setting in the presets for the video settings menu)

Well, if 10 frames per second gap in UT2K3 is good, then 20 in RTCW is better

Need I say more? This memory, in the right motherboard is some of the most stable around. For gamers good RAM is a must, and if you plan on overclocking then you need to invest in memory that will handle the bus speeds you want without having to sacrifice timing performance.

The 3DVelocity 'Dual Conclusions Concept' Explained:
After discussing this concept with users as well as companies and vendors we work with, 3DVelocity have decided that where necessary we shall aim to introduce our 'Dual Conclusions Concept' to sum up our thoughts and impressions on the hardware we review. As the needs of the more experienced users and enthusiasts have increased, it has become more difficult to factor in all the aspects that such a user would find important, while also being fair to products that may lack these high end "bonus" capabilities but which still represent a very good buy for the more traditional and more prevalent mainstream user. The two catergories we've used are:

The Mainstream User ~
The mainstream user is likely to put price, stock performance, value for money, reliability and/or warranty terms ahead of the need for hardware that operates beyond its design specifications. The mainstream user may be a PC novice or may be an experienced user, however their needs are clearly very different to those of the enthusiast, in that they want to buy products that operate efficiently and reliably within their advertised parameters.

The Enthusiast ~
The enthusiast cares about all the things that the mainstream user cares about but is more likely to accept a weakness in one or more of these things in exchange for some measure of performance or functionality beyond its design brief. For example, a high priced motherboard may be tolerated in exchange for unusually high levels of overclocking ability or alternatively an unusually large heat sink with a very poor fixing mechanism may be considered acceptable if it offers significantly superior cooling in return.

Conclusion:

For the Mainstream user:

Any system, from a desktop workstation to a full blown gaming rig can only benefit from quality memory . Of course this level of performance is only validated in a motherboard that can do it justice. If your motherboard has a FSB of 266MHz or less, then this performance of memory is overkill, save your cash unless you plan on upgrading soon. If you have a current board and are looking to improve performance, then by all means invest in quality RAM, it does a world of good.

For the Enthusiast:

I don't need to explain the benefits of quality RAM modules to the enthusiasts out there, you know what i'm talking about... Timings like I've reached with this memory are not a dime a dozen, and it takes a special breed of chip to run this fast. I ran into very few problems along the way, and probably could go higher by dropping the multiplier, but I wanted stability all the way (and I don't think that the results I got are half-bad) If you are looking to fill slots in anything above a KT333, then I highly reccomend XtremeDDR.

One word of warning: XtremeDDR is of a performance that is not compatible with all motherboards. In some isntances I have heard negative comment about this memory, and to be honest the first Zenith board I had gave me a lot of trouble with these modules (it was a launch sample that was the initial rev and it had a few minor issues), but after a motherboard RMA (for other reasons) the latest rev proves that this is very high quality stuff. So before you run out and order a stick or two, check their website and look at the approved motherboards list.
