32 GB installed shows only 16GB

post #1 of 26
Thread Starter 
I have Windows 7 64 bit ultimate so please don't ask me to check I have 32GB of RAM for my workstation and I only see 16GB I have done everything and switched the sticks out and bios flash but still it reads only 16GB CPU-z reads 32GB bu the rampage black 4 only reads 16GB so any help would be very nice beause I use this rig for school cause I do animation and rendering and 3D modeling so any help is very much welcomed.

Run this in Command Prompt - wmic MEMORYCHIP get BankLabel,DeviceLocator,Capacity,Tag

Check the Maximum Memory Windows is configured with - msconfig, Boot tab, Advanced options...., make sure Maximum memory is unchecked.

Report back with your BIOS revision and RAM module brand, model and speed.

You're on the release BIOS (0403) dated 10/28/2013 . Update to the latest BIOS revision (0701) dated 6/23/2014 or revision 0801 dated 7/14/2014 if you're comfortable with Beta BIOS. There is a note in revision 0801 that says "Enables 128GB (8x16GB) support by IM (intelligent Memory) memory modules", I would use 0801 only if 0701 doesn't solve the problem.

Was Maximum memory checked?

Did the output of Command Prompt read 4 DIMMs or just the 2 DIMMs you're reporting?

EDITED: The wording of the first few sentences to advise not using a Beta BIOS unless comfortable and tired typing.

How would I go to find A BIOS update?

There's a reason for the extra words after WMIC MEMORYCHIP, they're known as options and these will order the output for easier reading. Like this -


Go to your motherboard manufacturer's website, in this case ASUS.com. Hover over Products, Intel Platform, Socket 2011, Rampage IV Black Edition, at the top above the Windows 8.1 Ready logo click Support, click Driver & Tools, select your OS, expand BIOS and download the version you'd like.

Updating BIOS takes too long to explain, it's best to check your owners manual.

**Please re-read my previous post, I corrected a few mistakes.**

Does the mobo detect the additional RAM in the BIOS screens?

What's the default voltage of the DIMMs?

Before you go any further which slots do you have the RAM installed in? The output from Command Prompt reads DIMMs in 4 and 6. Your motherboard manual wants DIMMs in A1, B1, D1 and C1.

This is from your motherboard's manual, which is available on the ASUS site if you didn't know.



Not saying that this is the problem, but...worth a try.

NVM, I'm reading the output wrong. Time for bed.
