Why is it showing that I have 6 GB of RAM but only 4 GB usable?

SAkidichote, check it and put in your 6 gigs, but make sure after changing that the main page says "normal" for boot start up as it may change it to selective.

I'm going to try out Q-Flash now and I'll see if the option to configure internal graphics, or memory will show up in the BIOS configuration, and if not, then I guess I'll be clean installing the OS pretty soon. As before I reset the PC, the RAM was actually available for use for the whole 6 GB. My thanks to everyone for your eager display of kind spirits!

Just out of curiosity, could you please post screenshots of your:

Windows Task Manager "Performance" tab when in "Memory" graphs

CPU-Z's Memory tab

CPU-Z's SPD tab (for each slot)

(CPU-Z is a well-known third part utility)
Also, how is your memory physically distributed (slots, sizes, etc...)



Best regards

Isn't that setting only to configure startup memory consumption? As in the OS still uses the entire memory after booting up.

Nah it's the full thing. Typically windows will detect it correctly. Found a nice tutorial online for the Original poster.

Set Maximum Amount of Memory Usable by Windows -

I download the latest bios update from the manufacturer's site, I'm certain that I chose the correct model, which was A55M-DS2. I then extracted into a USB Flash drive, and restarted the PC to try Q-Flash in the BIOS, What I got was "BIOS ID check error." So that is no longer an option, at least for now.

Okay, here.

So, from those screenshots, I take it I misremembered that I had 6 GB of RAM installed when actually it was 8 all along?wow this makes it even worse now that it should've displayed 8 GB, instead it displayed 6 GB, and to add salt to injury only 4 GB is available.

Now I truly think that it's finally the time I consider clean re-installing Windows. Do you guys agree? Yes, I'm asking. I'm hesitant.

Correct, CPU-Z is detecting your memory as 2 x 4GB modules, what should give you 8GB available.This indicates you have 2 physical 4GB modules installed.

Simple test before reinstalling (what I think would NOT work): start the machine from installation media, and instead clicking on install windows, click "repair computer"

Then, "Troubleshoot" > "Advanced Options" > "Command Prompt"

Type:

taskmgr

and press enter.

It should open a "legacy" task manager (Windows 7-like), and you can find the available memory (in Mega Bytes) from there.



That is, if your BIOS can't show the installed RAM (what most BIOSes can do)

Have you tried typical troubleshooting steps to fix RAM issues, like exchanging memory modules between slots, test modules individually or cleaning contacts?

I, too, do not think that this will work ?you know, it's not like I messed around the system files so to restore, but for your peace of mind, I am willing to try.

I'll try switching, and I'll also try a rubber, before the above method, of course.

Have you tried changing memory configuration settings in advanced chipset features in BIOS ? ..
I think you need to have bank interleaving and channel interleaving enabled.
And there is one more option called DCT mode which needs to be set in ganged mode or unganged mode (try booting up with both).

There's no options for memory configuration in my BIOS menu.

thats strange . it should be in advanced chipset settings.
I am saying because I also have the american megatrends bios on a foxconn board with amd chipset and processor.

More options could be available if you press

Ctrl + F1

Ah, thanks! ....Gee, that could've been so helpful earlier!

Oddly enough, after everything I didn't think this simple fixation would actually fix it. I didn't even have to try the 'restore' method. It seems that I overlooked this easy step thinking it wouldn't change a thing—for that, I am sorry.
Here are the pictures to confirm the successful fixation.



Thank you everyone!!!
