Windows 7 – 2.92GB Usable Memory
July 30, 2012 / by Marco / Categories : Hardware, Technology
I thought I’d give my PC a bit of a boost today buy purchasing an additional 4GB DDR3 memory, which will bring the total memory to 8GB. So after removing the case and plugging in the new Kensington 4GB DDR 1333Mhz memory module in the motherboard slot I had all smiles on my face. I was very confident that my PC would run much faster after the install.
So after powering the PC on, I had a message from the BIOS that the amount of memory had changed. Thanks for picking that up BIOS – it meant that I installed it correctly. After loading Windows, I thought that I’d better check to make sure the Operating System also picked up the memory change. So I went into Computer Properties to check the amount of memory – it showed 8GB. Hurray… that was my initial thought. But then I decided to also check the task manager to see how much memory it picked up and it was 2985MB. It was one of those “WHAT THE!” moments.
That’s not right, I thought to myself. Actually it was more like “%@^&%^$”. I decided to do a bit of reading to figure out what was going on. After some researching, I found out something that that was quite interesting. Out of all the years I’ve been in IT industry I didn’t know that Windows 7 32-bit can only use 2.92GB of memory. So I went back to my Computer Properties to check if this was correct:
Yep – the OS showed that 2.92GB was only usable. As a result, I need to upgrade my operating system to 64-bit. Damn you OS!
Now it’s time for me to buy Windows 7 64-bit and reinstall all my apps. This will be fun!
