Solidworks Performance Question

[jwarnke]

I have a PC with Windows XP 64 on it and solidworks x64 2008. My pc has 4gb ram in it and when I run a benchmark, it takes about 180 seconds total(I/O about 55 sec.). If I keep everything the same, but use 8gb ram the benchmark runs the exact time. My I/O, CPU, GPU are all virtually identical to 4gb test. Why isn't it making a difference?

windows is recognizing i have 8GB as well.

If the test involves less than 4GB of RAM, installing more will not help.

It probably won't help, but try setting the Virtual Memory to the recommended minimum, or even zero.

x64 bit OS's are not for system speed, they are for increased memory allocation.

SolidWorks is CPU bound, if you want more speed you want to get a faster CPU.

CPU = speed
x64 = more memory allocation

In what situation would 8gb help then? Multiple program running similtaniously? Or would it help at all?

Rendering, FEA, large assemblies. Anything that casues your system to hit the limits of the 32 bit 4 gig limit.

Your system is slow because you have a slow CPU. AMD's have been way behind the performance curve for a couple years now. A fast Core 2 Duo in the 3 Ghz plus range will improve your speed.

You do not have a problem with memory. It is in the choice of CPU.
