Love to help nut unfortunately the snips dont enlarge. What I think is happening is the you are just not used to the fact that win 7 takes about half of your memory and holds it for the next request. This is a good thing makes launching and changing much faster.

Have you played with any settings in MSConfig by any chance?

yes i did, those two are uncheck.

Did you uncheck them yourself? Has this always been the case since you got the machine?

Only thing i can think off that might help, is ticking the max ram and setting it to 8 gig, and restarting...

let us know the result.

after ticked the max ram and restarted computer, nothing changed in phycial memory, and mscofig shows the max ram is 0 with the check mark on

Can you set the max ram from 0 to 8192?

Then restart, see if anything changes..

Going to have fun with this one if it is a bios issue causing it. That board may have been made by MSI, but it was made for the OEM market and as a reslut at least according to here,

Can't find MSI P55M-SD40 on MSI

is up to the computer manufacturer (ibuypower in your case) to provide any bios updates if that is what it turns out to be.

As Ken said your images won't enlarge, but enough can be seen to see that half of the 8 GB is hardware reserved. That can usually be caused by one of 3 things,

1. The setting in msconfig that Uber Philf mentioned.

2. Memory remapping is not enabled in the bios. This setting is usually defaulted to enabled with the option either hidden or removed in most recent bioses. It probably isn't there in yours, but have a good look through every section in the bios just in case.

3. For whatever reason the board only supports up to 4 GB of ram, which again brings it back to a bios issue as the chipset on the board is more than capable of supporting 8-16 GB (or more).

If the memory remapping option isn't available, seeing as you just got it I would start with contacting ibuypower and seeing hat they have to say; even more so if it came with the 8 GB and you're only using 4 GB of it.

it changes to 8192 automatically, but after i restarted, the max turned to 0. and i can;t find memory remap in BIOS, im using MSI P55M-SD40 motherboard

So nothing on memory remapping, anything to do with memory in there? Besides overclocking?
Sometimes they're under names like Memory Extension, Memory Re-Addressing etc etc?

thanks all the replies. probably, connecting to the manufacturer is the best option right now. thank you all appreciate
