GA-EX58-UD4P Ram problem

[Adoh2]

We recently rebuilt an oldish PC. It all went well apart from windows7 is only using 4GB ram out of the 6GB. It is detecting 6GB, just not using it.

I asked on a few other forums and they assumed that it was the motherboard. I've updated all the drivers and there is still no change. I have also reseated the RAM several times, swapped the slots around and no change.

I've tried updating the BIOS, but it just gives errors before even installing saying it cannot install due to my operation system being 64bit. There are no other BIOS updates for 64bit on the gigabyte site

I think it's fair to say I'm not overly techy, I'm quite good at following instructions though. So if anyone has some ideas as what to do next it would be appreciated.

Thankyou, Aaron.

Is it detecting in windows or the bios?

What slots do you have the memory in. They should be in the whites slots.

[Adoh2]

They are currently all in the white/grey slots. I've left all the blue slots empty.

Edit- Windows is detecting all three 2GB ram cards. It says it can only use 4GB though. Heres a screenshot of it - http://i.imgur.com/I2s4Dww.jpg -

You can update the bios from with in the bios. Just download the bios F13 and unzip it and put it on a usb drive.

Once the bios is updated shut down the computer. Pull the power plug clear the cmos and pull the battery.

Let it sit for a few mins. Unclear the cmos and put the battery back in and than go in set it to default settings.

In this link there is two ways to do it.

Thankyou, the F13 files installed properly.

Unfortunately within windows it still states that only 4GB is usable out of 6GB

One other place to check is in msconfig. Click on start and type msconfig and click on it. Click on boot and the Advanced option.

See what it says in there. The two boxes at the top shouldn't have any check marks in them. CPU & Memory.

I have done some reading and some people say you might have a bent pin in the CPU socket.

Plus is some people having the same problem. https://www.google.com/#q=GA-EX58-UD4P+is+only+showing+4gb+memory+out+6gb+memory

I checked the MSCONFIG settings first and they were all unchecked.

A few have suggested that my RAM may be getting 'shared' with my videocards so that's why the 2GB isn't accessible. Some others said to go into the BIOS and enable 'Memory Remapping', but this setting doesn't exist for me.

I'll give the CPU socket a look at tomorrow, gotta fix up some power leads. May as well pull it all apart.

Thankyou

I'm wondering if that 1791MB of 'shared' ram is being set aside, so only the ~4GB is accessible by the rest of the system. If that's the case, that's OK, the old GPU's only have 896MB of ram on them

I was going to say that it might be sharing memory. But with your board I wouldn't think so. I had 6 of the those boards X58.

None of them ever did that. But you are really good to go. There is really nothing you can do to change it. Other than get a better card.

Two other places to check you memory are in task manager & system information. Plus there is one other thing you can try.

Right click my computer. Properties / advanced system settings / performance / settings / in there change it to best performance.

This will change the desktop, but just right click on the screen and in there you can change it back.

It might help and it might not. But you really don't need that stuff running.
