6GB memory (2GB usable)

[Lief]

I had 6GB memory installed, but it shows that only 2GB is usable. After i turn off my computer and take off the memory then put them back on then it shows that 6GB(5.50GB usable). I'm using windows 7 x64 bit OS. Can any one help me out plz?

If it is staying at about 5.5GB available that sounds about right.

The missing half a Gigabyte is reserved for various pieces of Hardware to use.

Have a look into Resource Manager > Memory tab. That will show you how much is reserved for H/W (the leftmost gray area).

 

[Lief]

there u go, only 514 Mb is reserved for H/W

So is that problem solved or have I missed something?

yeah, the problem is that, it doesnt stay at 5.50GB. It always shows 6GB (2GB usable) after i turn on my comp, then i have to turn off my comp then give the memory a touch or a push and restart my comp, then the memory goes 5.50GB usable.

Post a screenshot of resource manager when it says there is only 2GB available.

Yes, that's what we would need to look at. Maybe the BIOS plays an act on you.

i can't get the screenshot of resource manager when it says there is only 2GB available, cause this weird thing only happens the next day when i turn on my computer. i shutdown and restarted my computer for a couple of time it still says 5.50GB usable, but it probably will turn to 2GB usable by tomorrow morning.

Well, no problem. We'll wait until tomorrow.

Well, the reporting is correct. But I wonder how your hardware could possibly use those 4GBs - that does not sound right. I would contact the PC manufacturer and ask them. One reason could be that there is something wrong with your BIOS and you need to flash a newer (or older) version.

ok, thank you very much, and just let me know what should i do.

As I suggested, call the manufacturer as a first step. Regarding BIOS issues they would know better than us.

I just checked for possable BIOS updates for your mother board and found that the last BIOS update was release less than a month a go with the tag 'Enhanced memory compatibility' .

If you do need to flash your BIOS all the upgrade/downgrade firmware is available to download at GA-X58A-UD3R (rev. 1.0) - GIGABYTE - Support&Download - Motherboard - BIOS.

Quick reminder concerning the above: If you've Overclocked and/or made significant changes to the system comfiguratin in the Bios, then ensure the Bios is cleared and re~set to the default configuration before proceeding with the Flash.

Ahhhh... so this is actually a hardware problem...

Take out your memory modules. On the strips themselves, clean the gold edge connectors with a soft pencil eraser... then brush with a paint brush to get the little rubber bits out. On the sockets... spray them with rubbing alcohol (aka contact cleaner) and clean gently with a soft toothbrush.

When you put your memory back in press very firmly to make sure the locking clips snap into place on both ends of each stick. Wiggle side to side slightly with your finger to make certain they are seated...

Now what do you get?

Most likely it's detecting all memory strips SPD but getting r/w errors during POST scanning so it flags it as unuseable.

From his description of how it comes back with a finger's touch, this sounds for all the world like a bad connection... probably just some dirt that got into the wrong places.
