As you know, WinXP is limited in its use of RAM to 3GB. One of the advantages of the 64 bit version of WinXP is that it allows the use of RAM up to 8GB. If one installs MT4 in the 64 bit version of WinXP in goes into X86, which is, presumably the "WOW64" emulator that runs 32 bit architecture programs.

Question: Does anyone know if, when MT4 is running under the 64 bit XP will MT4 utilise any additional RAM memory in excess of 3GB? In other words, is using the 64 bit version of XP to run MT4 a wasted effort?

Thanks in advance,
