OT, Weird RAM question?

I recently acquired a HP M7750N PC from Fry's Electronics because:
1. it was on sale CHEAP
2. it was on sale cheaper than trying to upgrade my old box

So far, I'm VERY pleased with it, I formatted the HD to remove
crapware, installed Vista Ultimate 64 bit and all is well but...

On the HP site it says:

Windows Vista comes in a variety of editions. All versions of Vista
have a minimum memory requirement of 512 MB (1 GB to take advantage of
certain premium features, such as Aero graphics). The maximum amount of
memory depends on the edition used:

Edition of Windows Vista Maximum addressable memory
Any 32-bit version of Vista editions Approximately 3.3 GBs
Home Basic 64-bit 8 GBs
Home Premium 64-bit 16 GBs
Business 64-bit 128 GBs
Ultimate 64-bit 128 GBs

My particular PC can only support 4 GBs of RAM but is it REALLY
possible to have 128 GBs, assuming that anyone could afford to buy that
much? Does anyone make a motherboard that could support that much RAM?

Last question, if anyone did have that much RAM would it really make
any difference at all for most applications? To me it seems like
overkill except for the person that has to have bragging rights....

Re: OT, Weird RAM question?

64-bit versions are limited by the software to 128GB.
I think it is mostly a standardization "thing." There's a lot of room to
grow.
The address bus on most 64-bit machines are 48-bit meaning it could address
2^48 addresses (a lot more.) But, I think there is some other hardware limit
that puts it at about 18 TB.

Most of us are limited by the budget to much less than that! ;-)

None of it makes any sense at all...

Why is Home Premium 64 bit limited to 16 GB but Business and Office 64
bit can have 128GB? It doesn't seem logical, why go to the trouble of
restricting one version and not another?

In reality, most motherboards won't take more than 16GB and many won't
go over 4 GB so it's a moot point but I'm still trying to see some
logic in it and failing. <sigh>

Re: OT, Weird RAM question?

Business editions are limited to 128 GB because that's what XP x64
supported.

Can you actually buy a mobo that supports 128 GB of RAM? Probably, though I
don't know of one off the top of my head. Certainly I can buy one that has
dual procs and 64 GB of RAM. (Tyan)

Who would use it? Ah, someone running really BIG CAD or other graphics
programs. Someone doing large rendering or emulations. IOW, a legitimate
workstation use where really large amounts of RAM are used and appropriate.

Why less on other editions? Marketing and market segmentation. No technical
reason at all.

And by the time the next version of Windows comes out, I expect my base
desktop machines to be running 16 GB. And my servers 4x that, at least.

Re: OT, Weird RAM question?

What would it look like? (Just in case you thought no one would ever use
that much.)
http://onlinearch.blogspot.com/2007/07/ever-wondered-what-128gb-of-ram-looks.html

Actual limits for Windows: (It's up to 2TB on some versions)
http://msdn2.microsoft.com/en-us/library/aa366778.aspx

A different article indicates it may be a limitation of NTFS.
http://technet2.microsoft.com/windo...f6a4-4ea0-8b78-df153663f6ed1033.mspx?mfr=true
2MB of NTFS space needed for every 1 million files of Paged Memory:
Limitation of 128 MB Paged Memory addressing (or 64 million files) This
creates a 128GB limitation on Paged Pool Memory for x64 system.
1 MB needed in NTFS for every 10 MB of Virtual Memory: Limitation of 8
TB.
8 MB needed in NTFS for every 1TB of Non-paged Memory: Limitation of 128
GB.

Re: OT, Weird RAM question?

Slightly OT perhaps, just to clarify something most people doesnt seem
to understand:

32-bit OS supports a total memory address range of 4096k memory. This is
by no way limited to RAM but is the whole address range for memory
"overall". This means you have to include graphics memory (512MB
usually), disk caches, all controllers for ports etc etc.

In the end, this usually means you are left with approx. 3GB addressable
memory after the addressing of the rest - on a high-end gaming machine
this could be way less, the effect of a 1024MB video card takes a huge
chunk out of this.

So usually, many people end up sticking 4GB of RAM into their high-end
32-bit rig and 2-3GB of that memory can be used - the rest is wasted.

(there are ways to software extend the address range, it works ...
sometimes ..)

And completely unrelated to the post to which you replied.
