Hi folks!

Just upgraded my media center and have installed 6GB ram? I have 2+1+2+1 The memory is Corsair PC6400 800MHZ xms2.

The bios sees everything. Even Windows says I have 6GB installed, but I get told that I can only utilise 3.5?

OK! What am I missing here? I thought that 64bit could use everything...

How much RAM does support hardware?

Which motherboard do you use?

Which chipset do you use?

Which processor do you use?

Hi cdob

I guess that is a fair question considering what I am asking....LOL.

OK!

The board supports 8GB DDRII800/667/533 and I am using DDR2 PC-6400 800MHz

The motherboard is an AsRock 4Core1333-FullHD With the latest Bios1.70 installed. The chipset Northbridge: ATITM RS600

- Southbridge: ATITM SB600.

The processor is a Intel Core 2 Do E6420 2.13GHz Cache 4mb

Hope this helps!

Is the "Memory Remap Feature" enabled in the BIOS?

Run MemInfo -r [1] and post the output here.

Hi

Mr Snrub

Your info worked a treat....THANKS for that!

Thanks for another tool I can use.....Have attached a pic..

Thanks a lot!

Have you enabled the option, like suggested by Mr Snrub?

the output looks strange. Have you used the 64Bit version of the tool? Also check under msconfig.exe->boot advanced settings that you don't limit the RAM.

Hi MagicAndre1981!

Yes. Mr Snrubs "Memory Remap Feature" is enabled and it works....

Sorry, put up wrong pic..... added right one now..

Checked the setting in start manager > advanced and no limit set there.

this looks ok. This is 6GB.

Run BCDEdit > bcdedit.txt and upload the bcdedit.txt here.

Looks like you're using the 32bit version of Windows and that one's limited to 4GB RAM

Do you use the latest BIOS?

Using latest bios as written earlier:

Windows confirms that I am using 64bit

Just to confirm, if you run resmon.exe and click on the memory tab, does it say the "missing" ram is Hardware Reserved?

Start -> Run -> type in msconfig and click OK.

Go to the "Boot" tab and click "Advanced Options."

Is "Maximum Memory" checked? If so, uncheck it.
