I am aware that video adapters consume some memory but 1Gb?????? I didn't have time to test it any further so I don't know if I could have come up with a combination that works. Please can you clarify this as Microsoft support say no issue but many forums report it is an issue. Total Physical Memory 4, I would understand if my hardware changed between Sp1a and SP2 or SP3 but it hasn't, so how can it not be a bug or limitation of something Microsoft implemented above SP1a?
From my understanding, the issue's were around Win XP Pro and this was an over-site of Microsoft when it came to Home user's who use Games or other Hardware, which now causes issues for them. There are a significant proportion of bit hardware drivers that don't function correctly with memory outside the normal bit physical address range. As of XP SP2, client versions of Windows don't attempt to map memory into that range to avoid such bugs. I don't have a problem with 4gb under WinXP SP1a as I keep pointing out and want to know, is this a Limitation or technically a bug Microsoft put in place.
While you believe it doesn't matter if it's Pro or Home, well the PAE as you call it was done as most user's were Pro user's and this took into account of Businesses. I still don't under stand when the Spec says Win XP supports 4gb while it will take around 1.
I'm not sure how to be much clearer. It is a change introduced in XP SP2 to work around driver bugs. Sorry, I know what you are saying, but what I was simply trying to say, it maybe a fix to sort that issue out, but surely it has produced another bug. Also is there any point of having mb, mb or higher graphics cards when you end up losing memory? Surely Physical memory is better than graphics memory or am I reading this all wrong, and you don;t actually lose any memory as it's all available?
Microsoft says it a hardware issue with my Motherboard, my Motherboard manufactures says it's not but how the OS addresses the memory. From what I understand the 1. The addressing takes up that space.
All of this is consistent with what I have read but I am still confused as to why this kind of backward thinking was taken up in the first place given the lessons learned from the days when K or RAM was all anyone would ever need Since the system needs memory address space for the hardware, that space will overwrite RAM space therefore causing problems if Windows thinks it can use it. I don't think there can be a fix to this because it is a hardware issue since motherboards assign the memory address space.

That seems to mean some of your RAM are wasted due to the address space issues, aren't they? Thus 1. Since some of your RAM are occupied due to hardware address space issues, does it mean my RAM have been wasted a waste of money to buy RAM that you can't use at all in any case? The above happens when I have 4 GB.
Why doesn't it happen when I have 2 or 3 GB only? Doesn't our hardware still need to reserve memory space or use some of my RAM? I wonder whether all these are display issues only.
How much RAM being shown in the operating system doesn't change the fact that my hardware has to consume some of my RAM. Am I right?

It isn't drivers or processes what cuts into the address space available for RAM. Because you can normally access almost 4GB.
Supports up to 8 gb of ram a. Flex mode allows symmetrical, Dual Channel mode for unmatched sodimms c. Dell Bios A09 supports 6 gb of ram 2 gb slot a, 4 gb slot b there are ideas on ideastorm to get Dell to write bios for 8 gb please promote d. Windows x32 vista sp1 a. Reads 4 gb of ram, uses from 3. Supports Turbo Cache Memory vista only 3.
Windows x64 vista sp1 a. Reads total installed minus any motherboard usage b uses all that is read my bios shows 6 gb, windows shows 5.
Supports Turbo Cache Memory vista only d. Thank you. With bit OS, it is not to be had. Very few users will ever be able to take advantage of even 3. X3lectric 3 Argentum. Message Edited by X3lectric on AM. Post Reply.
