Hello Everyone:


I recently upgraded my RAM from two sticks (with two slots empty) to four sticks (all slots filled).  After the install, all four slots are listed as empty in the BIOS.  They are also listed as empty when I run Belarc Advisor.  Windows, however, shows the installed memory as 15.9 GB (which is the correct amount).  The computer has been working fine since the install.


Any ideas why both the BIOS and Belarc are showing no RAM installed?  Clearly it is.  I tried pulling the battery from the motherboard thinking that would reset things, but that didn't work. 


I'd appreciate any insight.  Thanks.

Fuzzy here,,, but I believe most BIOS now have an "auto detect" to determine the RAM installed... but it may need to be enabled.

if what elfbane suggests dont work you may have to manually enter the ram. May need a BIOS update as well. Though, if it were me-as long as the computer is functioning fine, leave well enough alone.

Well sometimes you have to use the System managed option in Run>sysdm.cpl/Adcanced tab/performance(Settings Button)/Advanced/Change/ Untick automatically manage and then select "System Managed Size". restart and see what windows find then. Ive seen this happen with some of the HP Z400 series we have, this happened after installing more ram then the factory issued. I also note when you restore a factory image, it has to have the correct amount of ram as when it was released!!!!

Also, make sure you didnt get non ECC or ECC RAM when your motherboard cant handle it. 

I know this how... yep.  I did just that before.  Also, voltage, and enabling in the BIOS.


Sometime BIOS just needs a refresh to know that its there.


hope you got it sorted.
