[SOLVED] Installed Ram 16.0 GB (7.96 GB usable) #Win 11

[imogen99]

Hi there,
i recently upgraded my PC ram from 8GB to 16GB by adding another 8GB stick, using the same Ram module from the same buyer.
and changed my Mobo from ASROCK N68-VS3 to GA-970A-DS3P.

i made those changes without reinstalling windows, the PC started normally all working good, i made all recommended updates from windows and from Driver Booster 9.

all working good but the ram it's reads, 8GB instead of 16GB, the ram is 1866Mhz and i don't think it's read at it full speed.

i'd love to read professional users opinion on this small issue.
i mainly use my computer for school - i'm happy with it as it it is in case we didn't manage to a find solution for this small issue

thanks in advance

either ram is defective or you mainboard has hard time to run it, so its disabed

looking at your bottom picture, did you insert that ram in A2 slot in reverse?

 

[ex_bubblehead]

In addition to the above, unless both sticks came from the same factory matched package they are not guaranteed to work together.

Looks like heatsinks on ram modules are flipped.

ye, on a closer looks it seems that heatsink got a bit abused

 

[imogen99]

No sir, it's just the ram heatsink, that is applied in reverse, both sticks are inserted properly.
i can see both rams in CPU-Z and in system about.
i just can't manage to make both Rams work. Installed RAM 16.0 GB (7.96 GB usable)

mainboard has hard time to run it, so its disabed

sir, correct me if i'm wrong, but in this cases it's shouldn't be shown in system information.

 

[imogen99]

i'll be happy to follow any instructions and possible fixes, honestly i run out of ideas.

it shows you SPD eeprom. that a small chip on ram module, it just reads it and shows you that, that doesnt mean anything tbh

try reducing ram clock

 

[imogen99]

understood, is there a way to check if the system is neglecting the ram due to an issue in the hardwire or the hardwire is good and it's just disabled and can be enabled somehow (maybe reinstalling windows for example)?

bios disabled it, windows reinstall wont help
check bios system info, it should show you there 8GB ram aswell
have you tryed downclocking your ram?

 

[DRagor]

First test would be try each stick alone, see if Windows sees 8 Gb with each stick.

 

[imogen99]

good idea, i'll test now.

 

[imogen99]

i think the bios it shows 16GB

How can i hdownclocking my ram.

it does shows 16GB...do a quick test
run memtest just to see how much ram it shows

MemTest86 - Official Site of the x86 Memory Testing Tool

MemTest86 is the original self booting memory testing software for x86 and ARM computers. Supporting both BIOS and UEFI, with options to boot from USB.

doesnt have to be run for too long, just to see how much ram it runs on

How can i hdownclocking my ram.

Go into Advanced Memory settings and
set DRAM frequency to 1600mhz and
DRAM voltage to 1.65V.

The first thing you need to determine is if the motherboard is in fact reading all four of the memory modules inserted into the memory slots of the motherboard.

You can do this by looking at screen when the system is first powered on to see if the memory count is displayed by the bios.

Or by entering the bios where it will report the full amount of memory read.

If the bios reads all 16Gb or ram.

You must then check what version of windows you are running, the version must be a 64 bit version of windows os installed.

When you look at the system information option of windows it will report the physical amount of ram seen by windows.
And should be 16Gb.

If you find that 16Gb is not reported as the total physical memory fitted.
But the bios reports 16Gb of memory detected.

It means that the configuration of windows has been capped to see, or use only a set amount of physical memory in it`s configuration settings.

To check if the memory windows uses is capped.

Click on start.
In the search bar type : MSCONFIG.
Press enter.

A new window will open.

Click on the boot tab at the top of the new window.
Then click on the Advanced option tab.

A new window will open.
To the top left you will see a tick box for maximum memory.
If there is a value typed into the box bellow it remove all of the numbers.

Then un tick the maximum memory box if it is ticked.

Click ok
Then click apply.
Then ok again.

Restart the system.
Let windows load.

And again open up windows system information.

If it says Installed physical memory fitted as 16Gb.

Problem solved.
