With my 32 bit O.S. (XP sp3), there is a small issue detecting the available memory.
I have 4 Gb onboard, total memory is 3.4 Gb and available memory is 2.74 Gb (windows task manager).
IntelBurnTest detects correctly the 2.74 Gb of free memory but if I use this value or anything higher than 2.1 Gb, the program exits with the error: "Linpack32.exe not enough memory".
If I want to test completely my 2.74 Gb of available memory, I have to start 2 istances of IntelBurnTest and put 2100 Mb on one and 600 Mb on other or any figure which sum is less than 2.74 Gb.

Is it a limitation of the 32 bit O.S. or what?
