Windows 10: Most of RAM unavailable in Windows after upgrade

We have a CyberpowerPC Gamer Xtreme 1096 bought new in 2011:

CyberpowerPC Desktop PC Gamer Xtreme 1096 Intel Core i7 960 (3.20 GHz) 6 GB DDR3 2 TB HDD ATI Radeon HD 5770 Windows 7 Home Premium 64-bit - Newegg.com

It was delivered with Windows 7, a 2-TB conventional hard drive, and 6 GB RAM in the form of three 2-GB DDR3 modules. The motherboard is an MSI MS-7522.

Recently we upgraded it by replacing the hard drive with a Samsung 860 Evo SSD, and the RAM with four 4-GB DDR3 modules, being careful to place the memory modules in the correct slots per the motherboard user guide. We also did a clean install of Windows 10 Pro v1909.

Windows and the SSD run fine, but Windows reports some of the RAM as not being usable. The BIOS shows 16 GB.

In About Your PC, Windows reports:
Installed RAM 16.0 GB (2.99 GB usable)

In Task Manager > Performance, Memory total is shown as 3.0 GB.

In msconfig > Boot > Advanced options, the "Maximum memory" box is unchecked. If I check the box, select "16384" as maximum memory and reboot, the change is ignored and About Your PC still shows 16 GB total RAM, 3 GB usable.

Based on an online article, I went into the BIOS and looked for iGPU/internal graphics/onboard graphics or a multimonitor setting to disable them, and also to look for a memory map setting or render standby setting to enable them. However, I found no settings labeled with any of the above words in BIOS. (However, there are a lot of BIOS settings, including a MEMORY-Z section, that use other terms. It was unclear if any of them could be relevant.)

Any suggestions on what to try next?

Video card or RAM need upgrading?

Memtest: no errors after 10 hrs.
I'm going to perform the Primetest, later on. Get back to you on that.
I'm going to take it step by step, guys. I need to find the problem with this current computer. I might have to upgrade some components, so that it is still runnable. As for the new one, yes....i will build on it later. I need to find something decent 'gaming experience', all suggestions appreciated. THanks.

That's what the auto setting will do since you're over the 1333 mark it jumps to the next step which isn't listed or officially supported I assume by that ram.

At this point though I would suggest dropping the multi one step or .5 so that we can get something stable and possibly take the heat issue out of the picture for now.

 

Windows shows 8GB RAM installed but 4GB RAM is usable

Hi There,

I've just upgraded my pc from 4GB RAM to 8GB RAM. Windows seems to have detected this upgrade but why does it show as only 4GB RAM available. The following is what I have tried so far with no luck:

• I have tried the msconfig method on ensuring maximum memory is not checked.
• physically removed the new RAM and reinstalled it

Any thoughts/suggestions on how i can resolve this matter?

Thanks
