RAM issue on 7 Professional 64 bit

ShadowFalls said:

I recently updated my Realtek audio driver and found that upon restart I could no get any display. After disassembling and reassembling my computer several times I finally got it up and running again but with a major performance issue. Out of the 16gb of installed memory i have installed on my motherboard it use to be that 12 were detected by windows and 8 were usable......now it says 12 detected and 2 usable. Being a 3d modeler and video editor this is unacceptable. Can any one help?

msconfig has all ready been checked.

So you've gone to msconfig, boot, and advanced options to check it isn't set to a certain amount of memory? Have you also checked your bios to make sure it's not only allowing so much as well?

I would also help if you could completely fill out your system specs.

Look at my specs in lower left of this post. I will give you a idea of what is needed.

How much ram is indicated in the Bios?
Did you install your ram as per motherboard directions.
Your motherboard has more setting than most people will know how to use.
But for now don't mess with them. Leave them a default (Auto).
Just make sure your ram is seated properly and the little clips on each end are engaged properly. I would like to see more specs. on your ram. Look at mine.
Then go to Resource Monitor and upload this.

What I would do if it was my computer would be remove the realtek driver I just installed and reboot and see if Windows 7 will pick it up a different driver. My computer has 4 Nvidia HD Audio so I don't think that is a problem. I have seen this one time before and going by memory it was either the ram or the video card wasn't seated properly.
