If you’re planning on getting a new Windows 10 Pro PC, make sure to get the 64-bit version because it can support up to a whopping 2 TB of RAM.

When Microsoft launched Windows 10 over the summer, there were still some unknowns about it. One piece of information that was missing was the memory limits for the new version of the OS. Previously, Windows 8 had increased its memory limits to 512 GBs from Windows 7’s 192 GB for the 64-bit premium business editions, Pro and Enterprise. Windows 10 makes an even bigger jump, with Pro and Enterprise now hitting the 2 TB ceiling. Because of the memory address space limitations for 32-bit Windows 10; that remains at 4 GBs. Windows 10 Home 64-bit remains unchanged at 128 GBs of RAM.

The memory limits between client and server are starting to compete; leaving an awkward gap with some editions in the Windows Server 2012 family-like Foundation and Essentials at 64 GB. High-end editions such as Standard and Datacenter have a memory limit of 4 TB. It is not known if the next revision of Windows Server currently in development will up its limit. With companies such as Samsung now releasing 128 GB DDR4 memory chips, it’s not hard to see client systems, most likely powerhouse gaming machines and workstations with 1 or 2 TB configurations soon.
