Real-world gains from tightly-timed DDR?

I'm building a workstation to run ANSYS and CATIA, professional CPU and memory intensive applications (inly on a 16-proc Itanium does ANSYS reach it's software limits). So, I considering buying HyperX DDR400 memory (Athlon X2 is the processor). But mow much real world performance difference is there between say kingston Value RAm and HyperX? Here are the timings:

Valueram 1GB module: 3-3-3-7-2

HyperX 1GB module: 2.5-3-3-7-1

if you don't know how ANSYS responds to memory bandwidth, then I can tell you that it is somewhat like Video-editing software WRT the computer hardware - processor and memory intensive. ANSYS recommended specs are:
at least 2GB of RAM
10k rpm raid-0 HDD setup for page file.

So, what are the general gains from tightly-timed RAM vs. normal RAM in Video-editing, media format conversion, etc...........?

Real world performance for A64, **gaming wise**, is VERY VERY slim. W/ tighter timings I'm talking 2-5 FPS gain.

Here's a semi-good link that you can do some basing from: http://www.ocforums.com/showthread.php?t=352040&highlight=truth


But considering the timings you've listed w/ those two RAM sticks, I'm betting performance gains will be tiny
