I have recently upgraded my RAM to 8GB using all 4 slots. Whenever  I check to see on Speccy, PC-Doctor and my system (Windows) it just indicates that I have 4GB and am using 2 slots?

 

ASUS and HP sites both say that I can run a max of 8GB RAM. The RAM I am using was recommended by HP and Mr Memory for my computer and motherboard?

 

I have tried changing around the RAM sticks but this has made no difference.

 

Any suggestions welcome. ..

 

Motherboard:  ASUSTEK NARRA3 M2N68

HDD:  Western Digital blue 1tb 7200rpm

RAM:  Crucial DDR2 PC2-6400 800 MHz

O / S:   Windows 10 - 64 bit version

Hi,

 

Try this, remove all the memory and then power on the machine, it probably will produce some beep codes...

 

Disconnect the power cord and press the power button 2 times, reinstall all the memory.

 

Did you check if the BIOS is reporting all the memory?

Hi,

 

Still no joy with the discharge attempt as suggested. BIOS is reporting that memory bank 1 & 2 are "not installed" and memory banks 3 & 4 = 2048MB / DDR SDRAM. 

 

The strange thing is that when memory banks 3 & 4 are not in use (i.e. do not have memory sticks) then memory banks 1 & 2 are recognised when memory sticks are installed?

[SleepyDude]

What is the HP model of the machine?

 

The specs of all the sticks are exact the same?

You might check this too because it happened to me.

 

In the windows 10 search box, type "system config" in the results list click System config to open.
Click the boot tab
Click Advanced options
If Max Memory is checked un check it
Hit ok
Hit Apply
Hit ok
Restart for changes.

Check reported ram now.

SleepyDude: HP Pavillion a6411UK. Memory as recommended by ASUS, HP and Mr Memory - Crucial PC2 -5300 & PC-2 6400. Sites state the difference in MHz between the sticks will just mean the low speed will dominate.

zep516: Did as suggested. No luck, Same report as before.

You may need to do a BIOS update, I didn't have success locating the HP web page for that model!

 

Mixing different memory speeds may not work depending on the motherboard tolerance to that...

 

Did you try to change the order of the memory kits on the bank pairs?

 

If you install only the new memory the machine detects 4GB and work?

[dan7brit]

Yes, have changed order of sticks - no success.
Yes, the system recognises only the new pair of sticks as 4GB

The ASUS site did say that the motherboard supports the memory sticks I have installed.

Looked for BIOS update on HP site, but they said that the "product is no longer supported by HP".
Tried downloading Winsflash but all that said was that it could not find the "ATK driver"?

Hi,

 

Be careful I don't think the motherboard you have is from ASUSTEK! they have motherboards with reference M2N68 but are not the same.

 

Can you post what is the BIOS version you have now?

 

 

Edit:

 

Can you confirm that the motherboard on this link: https://support.hp.c...ument/c01357135matches what you have with SPDIF coaxial out and Firewire IEEE 1394

[dan7brit]

Yes, speccy says the motherboard is a ASUSTek and on the board it is stamped as M2N68 - LA. The same as in said picture.

BIOS is by Phoenix technologies 5.11 (2008). The updated version I have seen is version 5.17(2011).

[SleepyDude]

I can't find a reliable source for the BIOS update.

 

If you flash the BIOS with the incorrect file it will result on a bricked motherboard!

[dan7brit]

Ah! I also had difficulty finding a site that was reliable for an updated BIOS.
The strange thing is that the PC is running fine with Wins 10 and appearing to cope Ok even with just 4GB RAM. Makes me wonder if it is in use, just not registering?

[SleepyDude]

I doubt that because both BIOS and Windows don't report the 8GB.
