Reduced installed memory (RAM) ?!?!


I have had screen display freezing and computer not responding problem at random times and I took my PC to the repair shop. They tested it for a few weeks and said that the GPU was broken (they said they had graphics issue in BIOS).

I had 2 year old AMD R9 280. They told me it is better to buy a new GPU so I ordered a new one for my self from Amazon (UK) and i have ASUS NVIDIA GeForce GTX 1060 6 GB ROG STRIX GAMING GDDR5 now.

Anyways right after I got my new GPU installed and got my case from the repair shop i noticed that the installed RAM went from 6GB (3x2) to 2GB! I opened up the case and removed/installed them back again and this time it was 4GB! I did the same thing and nothing happened it is still 4 GB lol. I have been using it for 3-4 weeks cuz I had important work to complete, but now i want to know what's wrong with this computer?

Try using one stick of ram and testing each slot.

Then try a different stick of ram in each slot.

With this i may understand if one of the RAMs are faulty or if one of the slots are broken right?

(NT) Yes

do you also have an inbuilt graphics chip?

Any video hookup available on the motherboard itself? If so, that's shared RAM assigned to it in the BIOS.

I dont know much abouut that, but my motherboard is x58A gd65 by MSI if that helps.

Can I not disable the on-board graphics or any memory allocated to it? Or what should I do?

You do that in the BIOS.

When the computer is starting up, start pressing the key that will access the BIOS program on the CMOS chip. Usually it's the DEL key, but some computers use a function key. Most will say at the bottom of the monitor, during the POST period, before it begins the windows boot process, what key to press to enter the BIOS. In there you can find a setting to use your video card that's in the slot and turn off the onboard video, also can remove any RAM space that's shared to the onboard video, restore it for the operating system to use instead.

Missing RAM

Have you looked at the Motherboard Specs to see if it will recognize that much RAM? Certain boards are limited to the amount of RAM they can read. Also, are you absolutely SURE that it is seated correctly? I have had a similar issue in the past and I have built many PCs, so I was **Sure** that I put the RAM in correctly, but I didn't. when I inserted it correctly and rebooted....Voila! It was magically all right. Just saying...we all make mistakes eh?

Hope this helps.

We are going to need a bigger boat.

Or rather more reports. While my bet is the GPU forced the BIOS to kick the memory into dual channel mode or disable the non-matched stick we have a few tools to look around.

My favorites are the Web Speccy since you can drop a link and members can look around at the machine. How is at

To get "Memory type, size, timings, and module specifications (SPD)." we use and see what it's reporting.

That said, when I see this problem I want the memory sticks to be all of the same make and model, the BIOS to be current and if I want to see what's up, I use Speccy and CPU-Z.
