• Upgrading RAM
    4 replies, posted
Hey everyone! I've been planning for ages to upgrade my RAM because it is low for the things im lately doing. I render videos with sony vegas and that takes up alot of RAM etc. I already have insert new RAM "sticks" but they don't seem to appear. Now if I am right do I require to have 64 bits to be able to get a higher RAM? And I have read to have 64 bits your CPU needs to be compatible with 64 bits system. Would mine work with it? I very much appreciate the help I can get from you! OS: Windows 7 Ultimate 32 bits CPU: Intel I7 860 2.80Ghz Current RAM: 4,00 GB (2,96 available) Graphics: Gigabyte Geforce 660 Ti Kindest Regards.
You need a 64-bit OS to take advantage of 4GB of RAM and higher. A 32-bit OS will only recognise 3.2GB of RAM, if I recall correctly. Your processor is fine, but you need to upgrade your operating system.

I would think we are at the point we have no need for 32bit OS anymore, I rarely ever see a PC with less than 4GB of ram nowadays...

Your processor is fine, but you need to upgrade your operating system.[/QUOTE] A 32 bit OS can recognize 4 GB of RAM. The reason that Windows reports less is because devices eat into the 32 bit memory map. If you have a video card with 512 MB of VRAM, your available system memory will be 3.5 GB. But more than the GPU eat into the memory map, so less than that is usable. But in actuality, 32 bit Windows can utilize more than 4 GB of RAM by using PAE (up to 64 GB) but Microsoft has a dumbshit licensing scheme where they license the amount of memory you're allowed to use. There is a way to patch the kernel on Windows XP, Vista and 7 to remove the memory limit, but it's a pain to do and doesn't always work. The only limitation of PAE is that while the system can address up to 64 GB of RAM, each process can only use up to 4 GB of RAM; But it's still better than having truncated memory. Server versions of Windows and Linux can properly use PAE to address more than 4 GB of RAM in 32 bit mode, but they still have the 4 GB limit per process.
