Windows 7: 6 gb ram only 3.96 gb usable

6 gb ram only 3.96 gb usable

Hey guys , I just bought a 4 gb stick module and I kept one of my 2 gb sticks but even though both of them are installed , my pc recognises only 3.96 gb as usable.
Thing is that the 4 gb stick is "teamgroup 800 mhz" and the other one (2gb) is "kingston 667 mhz", so I was wondering if that could be the case.
I really want to to able to use all 6 gb, so what could be the problem?
Thanks in advance.

The speeds wouldn't matter I wouldn't have thought, the 800MHz would just run at 667MHz in line with the slower one. Download Speccy as linked in my signature, run it, maximise the RAM tab on the left and post a snip of the results.

The motherboard tab would be good as well.

I see two problems right off the bat.

Your temps in read for the motherboard. They might be a false reading but you must check.

Your +12v is very low 6.4 v. It also may be a false reading because I don't think the system would boot with that low of volts.

Please read the tutorials again.
Your Specs in the lower left of your post need to be filled in completely.
That will follow your every post so other members have a ready access to them and don't have to chase them down in the thread.

Look in the lower left corner in this post and tick on My System Specs and you will see what I mean.

Memory Controller volt indicate to high to the best of my memory.

I have filled up most of them, thanks again.
So what should I do about that? Could that be that recent update I did to my Mobo manually?

I would try using another monitoring program.

Here is a suggestion. Be careful and don't let it download garbage with it.

Download HWMonitor - MajorGeeks


Yes a bios update could cause the misreading of your system.

What was the reason you updated your bios?

Well my friend told me that updating my BIOS would be a good thing, so he found an asusupdater.exe or something and installed the latest update.

Less than 4.0 GB RAM usable?
It's funny, because ALL of my RAM was usable some time ago. (I have no idea how long ago this was, but it was on the same OS) I am using Windows 7 Professional 32-bit. I know about the whole 32-bit issue where some say you can't use much more than 3GB. Well, I WAS. I wouldn't be writing this...
