I have an intel pentium D 940 processor. I have tried ms config then check the maximum memory changed it to maximum, 6k+mb but when i click apply after restart it goes back again to 1025mb. I unchecked itstill its 3.25 usable, any helpful tips? and im running on windows 7 ultimate 64 bit. and it says in crucial.com that my limit is 4k+mb how to exceed?

my mother board is model is

You would need to provide more information for someone to be able to help. For example, the make and model of your computer and the RAM configuration. However, if I understand your question, it sounds like a motherboard limitation. You would not be able to circumvent that by changing a setting in ms config. If I'm misunderstanding, see if you can clarify your question. – fixer1234 – 2014-11-05T04:21:57.647

@fixer1234 how to find ram configuration sir? – DevLee – 2014-11-05T04:27:10.637

How many sockets, how many RAM modules in them? Can you identify the modules (memory size, other identifying information)? What did crucial.com say about the requirements and limits? I did a search on that model number and what comes back is an HP Pavilion that shipped with Win XP Media Center and 2 GB DDR2 RAM. Is that the right one? – fixer1234 – 2014-11-05T04:36:47.727

2In the detailed listing for that computer, it says there are 4 slots and the maximum supported memory is 4 GB. If that's the case, there is no practical way to exceed 4 GB. – fixer1234 – 2014-11-05T04:41:31.113

@fixer1234 crucial.com says

Maximum memory: 4096MB Slots: 4 (2 banks of 2) *Not to exceed manufacturer supported memory.

first slot is 2gb second third and fourth is 1gb each. *i thought it was 6gb all in all *

a have a high reserved memory like 1.7k mb

my mother board is EX333AA-ABA m7590n – DevLee – 2014-11-05T04:43:52.793

@fixer1234 oh, so even if i update my bios it still wont exceed sir? – DevLee – 2014-11-05T04:45:48.943

1It's not clear that you can use a 2 GB DIMM. It looks like the computer shipped with 2 x 1 GB. If you added the 2 GB, it looks like the computer is using 1 GB of it (which would not be a reliable way to achieve 1 GB). The limitation is in the motherboard design. The BIOS just recognizes what is there. – fixer1234 – 2014-11-05T04:50:43.150

@fixer1234 all seems to be clear now. thanks – DevLee – 2014-11-05T04:53:39.500

That motherboard is limited to 4 x 1 GB DIMMs. That is a design limitation. There is not a practical way to expand that and there are no settings (BIOS or MS Config), that can over-ride or circumvent that. This is a fairly old computer that was powerful in its day but pretty slow by today's standards. Even if there was a way to expand the RAM, the performance would be limited by the other components.
