Windows 7: Usable RAM question

25 Jun 2013   #1

Windows 7 Ultimate 32-bit
Usable RAM question

Hi everyone,

I have 2 OS on my laptop - Windows 7 Home Premium 64-bit and Windows 7 Ultimate 32-bit. The 64-bit version shows 3.5 GB of usable RAM out of the installed 4, but the 32-bit - only 2.3 out of 4. Interestingly though, the Windows experience index is 3.5 for the 64-bit OS (lowest value is for the CPU speed), but for the 32-bit version, it is 4.6, where the CPU speed is actually 5.6. My question is, can it be that the 32-bit OS reserved some of the RAM to bring these numbers up? If my guess is incorrect, can someone please explain what can be the cause of this, and if there is any way to bring the usable memory amount up in the 32-bit version.

Any help is very much appreciated = )

Type Resource Monitor into Start Search box, click on the Hardware tab to view how much RAM is apportioned to hardware from each OS.

I'd then watch the Task Manager Performance tab to observe how RAM is being used in both OS's. You can drill deeper into the processes using RAM with a program like Process Monitor which is described in Step 7 of Troubleshooting Steps for Windows 7
