Windows xp does not recognize additional memory




















The amount you can. It's usually around 3. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. I put 4 Gigabytes of memory in my comp Windows XP isn't showing this memory upgrade. Still shows 2. When I open task manager and look over my avaialable memory it shows only 3GB. Is this normal behavior for XP? Am I not getting full benefit of my investment in additional memory?

It should show either 3. This is more of a limitation of said chipset than a WinXP limitation. If you run msinfo32, you will probably see all 4GB of memory installed. That appens because WindowsXP 32Bit only recognize the maximum of 3Gb, maybe a little more, nothing about a chipset limitation But we all know MS words mean nothing.

Yet, I still think we may see SP3. Hopefully soon. I think there is a limitation as too how much RAM a 32 bit application can access Let me see if I can find more info.

I said maybe If Vista supports it why dont XP in future SP3, that i think is going to be out but never know what MS has in mind , can support it to? Im just thinking.. Remember that running processes do not understand RAM, they only understand their Virtual Address Space assigned to them by the kernel memory manager.

The memory manager then decides what portions of that Virtual Address Space get mapped into physical RAM, and what portions go into virtual memory the paging file.

There is a really important difference. The BIOS reports the drive model and capacity correctly. However, XP does not recognize it. The sticks are only about half as high as the original sticks. Any ideas on the memory would be appreciated. Not sure why your Drive is disappearing, but Windows XP 32bit can only see 3 to 3. XPS Core2, 2. Those addresses are assigned starting at the 4GB mark, working down. Exactly how much of the address space is used this way depends on the exact hardware installed in the computer e.

Most 32bit systems with 4GB of physical memory installed have between 3. The advantage of having a full 4GB, despite not being able to use it, is that it allows dual channel memory for the system.

We now know the drive itself is bad. Having determined this, I have a question. How can one check the power supply and SATA ports on the motherboard to ensure they are not a problem? My drive was under warranty, and Western Digital is sending me a replacement.

I do not want to plug it in and have it go bad due to a cause related to something else that could have created the first problem. I suppose the two items which could contribute to a hard disk failure other than the drive itself are the power supply and the SATA ports.

So I would like to check those if I can. Would it make sense to replace the power supply that came with the XPS with a larger and better one?
