Maximum Windows 7 memory allowed?

[sLiDeR]

Hi all,

Just wondered if ya knew what the Maximum Windows 7 memory is allowed?

I know XP & Vista is 4gig.

Only in 32 bit, 64 will will allow you allot more

This will tell you exactly what you need to know - [ame=http://en.wikipedia.org/wiki/Windows_7_editions]Windows 7 editions - Wikipedia, the free encyclopedia[/ame]

The same applies for both XP and Vista - the 64bit versions will allow a lot more - it's not to do with which windows you use, but the type of computer you buy them for. If you buy retail windows (vista or 7) you get both 32 and 64bit.

It is basically a combination between what the Operating System will allow ( dependant on if it has or uses PAE - physical address extension )

And also on the hardware - because if you only have 2 memory slots then you are limited to the maximum amount that the motherboard will support so if the motherboard will only support 1gb per memory slot then thats 2gb in total ( obviously if it supports 4gb per memory slot then that will be 8 gb in total )

W7 32-bit will be 4Gb, when it comes to the 64-bit editions, the amount of memory that the OS can handle will depend on what W7 edition you have.

Windows 7 64-bit Memory:

* Starter: 8GB
* Home Basic: 8GB
* Home Premium: 16GB
* Professional: 192GB
* Enterprise: 192GB
* Ultimate: 192GB

Unless im missing something ( not an impossible occurance ) but I have not seen a computer with 192gb of RAM

The technology is here today!

The Dell Precision T7500 has 12 RAM slots which can take upto 16GB each

12 x 16 = 192GB

These would be artificial limits set by M$. The AMD64 architecture has a 52bit address space which is 450Tb. A full 64bit address space is 16.8 million Tb

See limitations here...

So where would you get a hold of 16gb memory modules as I have only seen crucial do up to 4gb per memory module ( 2 * 4gb memory modules ) which is an 8gb kit

One of our clients is running a SQL box with 64Gb of RAM.

That's pretty cool

Both HP and Dell have server boxes that support 256GB of RAM I am guessing that IBM and Sun must do as well.

I've never tried or looked into, never had a need, but I've seen quite a number of people on the internet proclaiming that by replacing certain files in Vista with files from Server 2008 (32bit supports more RAM than Desktop) that you can get Vista to address more than 4GB of RAM.

I assume if that's possible, the same would apply to Win7 and 2008 R2 files?

[mac_shinobi]

ive never looked into it either but looking on the buy it now page of that Dell T7500 they dont offer an option to get 192 gb of ram so not sure how you meant to do it ( ignoring the amount of money it will cost obviously )

I can upgrade to 32gb and thats more then enough for me
