2-3% Improvement
While bandwidth is still very important to the Intel Pentium 4, it's not as important as it once was in the i845PE days of single channel memory controllers. Thanks to the i865PE/i875P's dual channel memory controller things are much brighter. On average, the system with the memory running at 400 MHz (5:4 memory divider enabled) with aggressive memory timings performed 2-3% faster than the system using high speed memory with loose timings.

While that may not seem like a lot to most people, it can make a world of a difference to the enthusiast, especially if you're gunning for that high score in a clan match where every FPS counts.

It seems as if all the large memory manufacturers/suppliers are afraid to lose face by not pumping out high speed memory modules with lax memory timings just so they can list them in their product lines. Many enthusiasts I know, tend to favour slower memory which allows them to run aggressive timings however.

One might say that the benchmarks we used were stacked against memory that uses conservative timings, but if you think about it, games and simple 2D applications are the programs that most consumers run where speedy performance really is important. That's why we ran the benchmarks we did; office environments with their servers or workstation PC are more interested in stability, and overclocking has an element of risk involved for both hardware and software.

Athlon64 based systems seem to act a lot like the 800 MHz FSB Pentium 4 processors in regard to their memory bandwidth and timings when overclocked. However, before conclusions can be drawn in this field, more research has to be done before....

If you're in the market for new memory for your Pentium 4 system and you're only thinking about gaming performance, then you're best bet is to get DDR which is rated to run aggressive timings. Some examples include Mushkin's PC3500 Level II which is rated to run 2-2-2-5 at 217 MHz FSB or Corair's TwinX-3200LL which are rated for 2-2-2-5 at 200 MHz.

If you're a newbie/novice overclocker and would prefer to buy something that takes a little less work while still producing good numbers on your Pentium 4 system, then by all means get some of the high speed DIMM's that are available on the market. They're not quite as fast as the low latency modules as we've shown, but they're much easier to set up. Now for AMD systems, because the AthlonXP cannot hit as high speeds as the Pentium 4 in general, it is always best to pair an AMD processor with nice low latency memory for the best results.

hoffe das regt diskussionen an
