Why does Windows 7 x64 see 3066 MB out of 4096?

Question

Windows

Two scarves of 2 gigabytes. I insert one at a time - everything is fine, as it should be.

Rearranging the handkerchief in places gives the same result (3066 out of 4096).

Task Manager sees a total of 3066 MB of physical memory.

The system sees 4 gigs, but 2.99 is available.

msconfig -> Boot -> Advanced boot options -> unchecked (Number of processors and Maximum memory)

I didn't find remapping in the BIOS (maybe it's not there?)

Why else can 1 gig be lost? And how will it fix it?

Answer 1

Is the motherboard very old? Bios version latest?

Answer 2

Answer 3

In the Azusovsky bios, there seems to be a fat called PAE (Physical address extention)
Was the memory working or linking before?
Did you run memtest?
I just have a similar situation with a friend. I had 2 sticks of 2 GB. And all the time the blues flew out. I bought another memory and gave this one to a friend. He also has blue spots and with two strips only 2 GB is visible. Millet broken memory. Mb is the same for you.

Answer 4

Is Windows 64 bit?
There could be two versions x86 and 64 on the disk. maybe the one that x86 was installed

Answer 5

On ASUS motherboards, your problem is solved by enabling the "Memory Remap Feature" option in the BIOS.

Answer 6

If none of the above could try opening msconfig => Boot => Advanced options, in the window that appears, check the “Maximum memory” checkbox and the size of the installed memory in megabytes, click OK and reboot.

Answer 7

As written above, the problem is solved by enabling the Memory Remap Feature option, it would be nice to see how much the BIOS itself recognizes memory. If it sees only 3GB and this option is not there, then everything rests on the mat. board, first you need to reflash.

Answer 8

msconfig -> Boot -> Advanced boot options -> unchecked (Number of processors and Maximum memory)
Using this method, I increased my memory from 6.5 to 7.12 (out of 8 GB physical)
