Only 4 Gigs of Ram but I have 8?

SMH___ · Sep 4, 2016

Hey everyone.

Recently got an asus m2n68-am plus motherboard, and the official website says it can support up to 8 gigabytes of RAM. I have 2x4gb cards installed, yet I only have 4 gigs avaiable. Both cards work as swapping them did no difference, and the slots themselves work as I've tried other ram cards as well. The task manager also says that it's using 2gb/4gb ram. I'm using windows 7 pro.

is it a 32 bit version of windows? that would mean no more than 3.5 GB or so.

SMH___ · Sep 4, 2016

It's Windows 7 Pro - 64 Bit

can you get CPUZ installed? it might be able to show wether it is a bad RAM slot. have you tested other RAM slots?

SMH___ · Sep 4, 2016

I installed CPUZ, yes, what now? And there's only 2 ram slots and both of them work as I've tried booting up with only one RAM card and it worked in either slot.

go to the memory tab what does it say about the memory? can you post a screenshot of it?

although it is seeming the person at ASUS had the wrong info. it seems the board only supports up to 4 GB. although how it could use 4GB in a single slot then seems odd.

There is sometimes a misinformation in the nomenclature of some RAM. I've come across this on several occasions here on Tom's. A person purchases what they believe to be 2x4GB RAM Kit, believing they are getting a total of 8GB of RAM, whereas in fact, they are purchasing a two piece 4GB RAM kit (2x2GB).

If you could provide us with the model number on the sticker of the RAM modules, we should be able to clear this up.

so when you have a single stick it it still says 4 GB right? CPUZ saying 4 GB means that the motherboard is only seeing 4GB, so that would reenforce the idea that this motherboard really only supports 4GB.

@Wolfshadow , they are both 4GB cards, when I plug only one in, it says 4 gigs total, but if you really want I can get the number off it
@Robert but then why would they say 8 gigabytes on asuses official website?

Robert Cook · Sep 4, 2016

can I see the link to what page were you on? when I looked up the board it said nothing of supported RAM besides DDR2, other sites then clarified to 4GB.

2 x DIMM, Max. 8 GB, DDR2 1066*/800/667 ECC,Non-ECC,Un-buffered Memory

shoot I was looking at the non plus board. okay what is your processor?

SMH___ · Sep 4, 2016

AMD Athlon II X2 250, 3GHz

Robert Cook · Sep 4, 2016

Wolf you think and old BIOS could be behind this? the CPU does not seem to have a real RAM limit.

SMH___ · Sep 4, 2016

is it a good idea to reset the motherboard to fabric settings and update the bios?

Robert Cook · Sep 4, 2016

that cannot hurt. worst comes to worst it still only takes 4GB.

Robert Cook · Sep 4, 2016

just take your time with updating the bios.

SMH___ · Sep 4, 2016

deleting and updating the bios did not work sadly, any other sugggestions?

Robert Cook · Sep 4, 2016

let me go see if I cant get another person's view on this

This is a common problem with AM2 and AM3, bent pins on the CPU can often cause this issue. I know this isn't exactly fun to do but if one or two pins are even slightly off it can cause this issue.

Robert Cook · Sep 4, 2016

ah thanks for the input!

The memory model does matter. I have found a few systems that will not work with single sided 4GB modules and others that wont work with some brands.

What is the make and model of your memory? Does it show up on the Asus QVL list?

I looked at the manual and it is saying you can install up to 2GB modules into the DIMM sockets however the QVL list does show that a Samsung 4GB module is supported. I wonder if the site is wrong. Might have to contact Asus support to see which is correct but most things are pointing to that board supporting only 4GB total RAM.
