Maybe I do, and maybe I don't...

I've been using this computer for a few months. A Dell Dimension 4600, Windows 7 32-bit Ultimate, 3 HDDs (Maxtor 80GB, WD 80GB, Seagate Baracuda 40GB), Intel P4 HT 3.06 Ghz, 1.5 GB RAM, Nvidia Sparkle GeForce 9500 GT 1GB DDR2

When I installed Windows 7, I accidentally inserted the 64-bit DVD and didn't notice my mistake until it told me that my system is incompatible and that I need 32-bit OS.

Installing the 32-bit version of Windows 7 was no problem and I've been using it fine; however, a few minutes ago I noticed something odd.

I did a DriverMax scan to see what updates are available and attached is a screenshot of part of the DriverMax results. The results indicate that I have a Dual Core Processor but that it's only 32-bit/x86 architecture. Is that accurate? Or am I reading this information wrong?

If this is accurate, I need to figure out how to install the 64-bit OS, upgrade my ram to the 4GB (max supported by this mobo) and utilize the full capacity of my system.

Thanks

The Pentium 4 is a single core CPU that has Hyper Threading which makes it look like it has dual cores but it really doesn't.

killerx525 posted while I was looking up info, but yes, Family 15 Model 2 is a Northwood 32-bit CPU with Hyperthreading. You'll only have OS access to typically 3.25GB (but can be less) out of 4GB of RAM, but this is still going to be up to double what the system currently has available. Even if the CPU had 64 bit support, the motherboard might not be able to utilize it. Mainboards with a maximum capacity of 4GB usually cannot translate the upper 1GB of physical RAM into the address space above 4GB where it needs to be in order for a 64 bit OS to access it, so the OS still only sees the smaller amount.
