I have googled the crap out of this and found nothing.
Are they going to raise it to 32GB or are they going to keep it at 16GB?
Thanks

That probably depends on which version you have.

For example, Windows 7 Professional and Ultimate can use up to 192GB of RAM. Only the Home version is limited to 16GB.

Windows 8 Standard supports up to 128GB of RAM. The Pro and Enterprise versions support up to 512GB.

He mentioned Home in his post, so that's probably where we should focus.

I'm betting a bit that it will be at least the Win 8 standard amount if not more. I have the option of buying a Win 7 home or pro license when I put together my current machine last month, knowing Win 10 was coming for free. I have 32GB of memory, but since I don't use or need any of the features of pro versions I went with the Win 7 home version in the hopes that on Win 10's release I will have full memory access. If Win 10 is a step back on memory limits from 8 Microsoft will have some explaining to do.

What an arbitrary feature to gimp, anyway.

It was actually one of the few useful features they could gimp and get away with it. Most of the other technical differences between Home and Pro/Enterprise (and Ultimate in Vista/7) are things that are pretty much irrelevant to home users. But the memory limit differences were used as specific a selling point, despite the fact that most home users at that time weren't utilizing more than 8GB of memory anyway (with many doing fine with 4GB).

I think I saw a posting on one of the Microsoft forums a while back confirming that Win10 x64 will continue to have the same limits as Win8/8.1 (i.e. 128GB for Standard, 512GB for Pro/Enterprise), while 32-bit Win10 x86 will continue to gimp along with a 4GB limit.

There may also be limits based on the CPU or the Motherboard. Most motherboards at the present time are limited to about 16-32 based on specific chipsets and implementation of RAM slots and Memory controllers.

There is a point that manufacturers may be purposely limiting users to get them to buy a more expensive motherboard with higher RAM capacity.

Honestly, it's not even a bullet point worth mentioning anymore.

If you're going to put more than 128GB of RAM in a home PC, you're more than likely using it for some sort of professional-grade application (3d modeling, video editing) and can more than afford to use a professional version of the OS seeing as how you easily just dumped over $1000 on RAM.

You're also think of it from a consumer perspective, think about it from the other side. If they *didn't* limit the memory capacity and restrict the ability to join a domain, as a business buying a fleet of workstation class PCs why *wouldn't* I just buy them all with the Home version? A $50 difference over 1000 PCs is $50,000 saved.

32-bit Win10 x86 will continue to gimp along with a 4GB limit.
I'm surprised they're even releasing a 32 bit Win10. Do they even manufacture processors that don't support x64 anymore?

How much RAM does each edition of Windows 10 support?

Edition


Amount
Windows 10 Home 32 bit 4 GBs
Windows 10 Home 64 bit 128 GBs
Windows 10 Pro 32 bit 4 GBs
Windows 10 Pro 64 bit 512 GBs
Windows 10 Enterprise/Education 32 bit 4 GBs
Windows 10 Enterprise/Education 64 bit 512 GBs

You mean I can't install Hyper-V on Windows 10 Home?? This is BS :colbert:

32bit Windows 10 for tablets obviously (most don't even have a 64bit capable BIOS).

Even later revisions of Atom-based processors are 64-bit. There's absolutely no technical reason modern tablets running Windows 10 would *have to* be 32 bit.

Well no technical reason, but stupid product managers, or they get the 32-bit chips for cheaper vs the 64-bit

for example bulk order of 5000 32 bit chips is $5 per chip
bulk order of 5000 64 bit chips is $15 per chip


Wonder if the IoT version of Win10 is going to be limited to 32-bit or will it be 64-bit as well.
That I could see a reason for still having 32-bit

True. But there is a slight advantage in power consumption and, more importantly, a lower memory footprint and better utilization of the often limited memory and HDD (or rather eMMC) capacity in tablets.

I have two windows tablets both with Z3735 and Z3770 which are clearly 64bit yet runs 32bit Windows 8, Ubuntu has a BIOS workaround to installing a 64bit Linux through a 32bit BIOS on many of these tablets.

It's quite dumb if you ask me.

They don't even have 128 bit processors yet!

There's no way around that. With 32-bit addressing, your limit is 4GB plain and simple. The fix is... 64-bit.
And no need for a very long time. 64-bit allows for 16 exabytes of RAM. Long time before we get there.

Well to be honest even before the hypothetical 128-bit processors, it would be nice if we can get stuff to work better with multi-core cpus.

Possibly. The apps that I would like to use the processing power of multiple cores (video editing) have that capability, and the games I play are only limited by the video card I have. So maybe you could tell us (or me anyway) what else you need to take advantage of more than one core? Anything that I felt was slow in the past has been pretty well taken care of with my SSD.

Memory-wise, I have never felt limited since going 64-bit. I suspect the high limits for 10 are due to the fact that they don't want to have to mess with that aspect for a good, long while.

Actually, it isn't so plain or so simple. The 4GB memory limit on 32 bit Windows is not actually a technical constraint, but rather an artificial limit based upon a business choice made by Microsoft. 32 bit Windows 7 (and even back to Windows Vista) contained code to allow use of memory above 4GB. Microsoft just chose not to license 32 bit users to be able to use that code. Probably to protect 32 bit users from poorly written drivers with issues handling memory access above 4GB.

You can actually patch the OS kernel to use PAE to access over 4GB (there was an old thread in the OS forums where somebody actually provided a kernel patch that worked to do this by throwing Windows into Test Mode). I ran it on a couple of Vista and early Win7 boxes with no problems for almost a year. However, due to driver issues, it may not reliably work on every system configuration.

Well, PAE is a different story and from a business standpoint I don't expect Microsoft to throw in and support an Enterprise level code to increase the memory limit on home machines. It's a stop gap measure that should just die.

It is effectively dead since there is no more 32-bit Windows Server OS and it's not enabled for the client OS.

The new limit is now going to be the artificial caps Intel puts on desktop SKUs to force people to buy Xeons.

On the Windows side it is. I believe Ubuntu still supports it, but how many 32-bit CPUs are still floating around out there? The only one I have left is a P4 3.0C from 11 years ago.
