Memory limitation on 32bit ?

[Joachim Damm]

Hi,
I have a question.
I used PerformanceTest 7.0 (32bit) on a Windows 2003 R2 Enterprise Edition Server with 20 GB of RAM (using PAE) on a Virtual platform.
Because the memory mark is quite low, I do some investigations on the platform and found, that 32 bit PerformanceTest is only using 4 GB of RAM.
Since the memory mark is in direct correlation to the amount of RAM, the measured values are plausible.
My question: Is there a possibility to use more than 4 GB of RAM in the PT7.0 32bit ? or any other version to check Windows Enterprise Editions with more than 4 GB RAM ?

Yes, the 32bit results will be lower than the 64bit results. Both the CPU results and the memory benchmarks.

There is no reason to use 32bit for anything any more. With 20GB of RAM you are nuts to use 32bit. PAE doesn't solve the 4GB problem (in fact technically it is a 2GB problem), because 99% of applications are not PAE enabled, and even those that are PAE enabled are inefficient compared to 64bit.
