[Du hast mich?]

Hello I have a problem with my RAM I can use only 3,94 of 8GB memory...
I have 64x bit Windows 7 Ulitimate and my Motherboard is ASUS A88XM-PLUS here is video of it. https://www.youtube.com/watch?v=VmRmTLa-0hc
I can´t find a remap memory feature or anything like that ..
Can someone please help?

Windows says 8gb detected 3,94gb usable. BIOS says 4096 usable but it detect 2 x 4096 in the right slots but it is using only 4096 of 8192 why then?

Have you tried memtest? Maybe one module is dead.

Yes let it run for 1hr at lesst...sounds like one of your dimms is dead

It aint dead if 8GB are detected. There wouldn't be 8GB to speak of, they're just not being used. Did you buy one of those modules after the other? are they different RAM modules?

Heres your NB https://imgur.com/DBPRaUK under advanced settings.

From there go to "integrated graphics", and set it to manual, or "force" whatever it is you have there. Save and exit.

what are you specs according to steam?

I have bought full pc i have not build it. And I haven´t there an option called NB configuration. It can be caused by that i havent the newest board drivers?

This is the manual for the ASUS A88XM-PLUS http://dlcdnet.asus.com/pub/ASUS/mb/SocketFM2/A88XM-PLUS/E8561_A88XM-PLUS.pdf?_ga=2.145209527.2096947618.1520710762-776443235.1520710762

On list of contents, 2.6 is advanced options. Northbridge and its configuration are within.

2.6.4 specifically, refers to NB Configuration, IGFX, primary video device, integrated graphics, and UMA Frame Buffer, which is what directly controls how much memory the integrated chip will be using, if any at all.

If you cant find and edit any of this, then i dunno, good luck.

Hello,

I think that a OP's friend who knows better tech wise or a technician should check and update BIOS of the mobo, if there are essential fixes.

@OP: Don't try this on your own, it's too early.

[R.O.T.O.R.]

maybe post your system specs according to steam

I have found a possible problem.... Downloaded CPU-Z and it is showing me that I am running in Single Channel mode.. How can I switch it?

Put a memory module in another memory slot. Like 1 in the first and 1 in the third slot. That is not going to solve your main problem though.

It might be that your brand+type of memory is not compatible with your motherboard? It is pretty rare that this is an actual problem, but might be worth giving a shot. Asus normally has a list of compatible parts on their support site.

I had a look at the video you posted. Go in your BIOS and change:

[AI Tweaker]
AI overclock tuner: "auto".
Memory frequency: auto".
(These are the first 2 options. This is just to play it safe.)

Then go to the [Advanced menu] and enter the following submenus:

> [CPU Configuration]
Check if everything here is either set to "enabled" or to "auto".

> [NB Configuration]
IGFX Multi-monitor: set to "disabled".
Primary video device: set to "PCIE".
Integrated graphics: "auto".

If you still don't see the [NB Configuration] option, look around all submenu's until you see the IGFX option. There always is an option to either turn of the IGPU or to give priority to the deducated GPU.

Evidently make sure that your monitor is hooked up the the HDM or DVI port on the dedicated card, not to the motherboard backplane.

Note: if you ever add extra memory to your PC, it is advised to turn the IGFX multi-monitor back to "enabled". But leave the PCIE as primary.

FYI: in the Tools menu in the BIOS is an option called "ASUS SPD Information". That will also give you information on your memory modules if you want.

Those options aren´t there ... I don´t know why

Your second SIMM is in the wrong slot on your board. They are either paired 1-2 1-2 or 1-1 2-2. If you put them in wrong this is the behavior you get.
