Hello , i get this weird usable ram in my control panel , i dont know how to fix it , i tried unchecking the max memory in the msconfig and it didnt fix my problem , i have an Intel DQ45CB mobo and on the specs it says it can use 16GB of memory max , however , when i am going to my bios settings and change the speed of RAM from 800Mhz(currently using) to 667Mhz suddenly i dont get the usable memory anymore , whats the problem in this case and how can i fix it?

Do you mean 15.64 and 16GB or what? And what are you specs? How much ram do you have? Is this motherboard a Zxxx chipset?

There likely isn't a problem at all. If you have 6.00GB of memory, and windows is saying 5.46GB is usable, that's not unusual. Windows itself will use some of your memory, and a little over a half a gig isn't really unexpected if you are running Windows Ultimate.

@herc08 my mobo is a DQ45CB an old 775 socket , and on the intel site it says it can use max 16 GB of ram , specs; CPU:Intel core 2 Duo E8400 , GPU:GTX 550 Ti and Kingston ram , 2x2GB and 2x1GB , @steve_170 i know but why when i decrease the speed of ram problem dissapears?should i disable the paging file option in advanced system settings?

Dont change anything. It is 100% normal for windows to borrow some RAM. I personally have access to 15.9/16GB.

Ah, I see now. I was confused, thought you had 16GB. Yes, it's called reserved memory. Just like when you have 1TB hard drive, you really don't.
