Attension H55/h57 users!

Hello everybody. Im having this weird issue: im using MSI H55M-ED55 Mobo, i3 540 CPU, Wintec 4Gb(2x2Gb) ddr3 1333, GTS 250 and win 7 x64. In system properties it shows that only 3.87Gb of my memory is usable. Here is the question: im using dedicated Videocard and 64 bit operating system why all 4gb of memory is not usable, i assume onboard graphics reserves part of 4Gb ram, but VGA in bios set to PCI-E, not to onboard. Is it common for all h55/57 boards, or smth is wrong? Ive already tried everything there is no memory remap option in bios that i was suggested to enable, i also updated bios to latest version. Anyone whos using H55/H57 boards and dedicated video - are u having same memory readings??

ive tried to contact msi tech support but got this answer: Dear Customer, As long as the bios is detecting the correct amount of memory you will need to check Windows 7 for a needed patch. Also if the System Information if detecting 3.8 that is about right after the OS gets done with what it needs. So please do check with on the Microsoft Knowledge Base. Thank you,
Not too helpful at all.

Here are results of my calculations, as you said all in bytes, i ont see anything close to 137Mb:

But i guess it could be combination of several elements?

what i've noticed here is that although PCI Bus reserves 249 102 335 Bytes - the sum of all sub-elements is 114 818 302 bytes, so 134 284 033 bytes are missing. Im not sure if it means smth but it is suspiciously close to 137mb of my "hardware reserved" RAM.
