Windows 7: 16 GBs of RAM not working on ASUS motherboard

Wow! I just took a look and there have been a few BIOS updates that deal with memory issues. I would jump right up to version 2105. That will contain all of the previous updates.

Hang tight, I've got a step by step for the safest way to flash the BIOS around here somewhere....

EDIT: Found it. You should use Asus EZ Flash2. Very safe if you follow the instructions:

EZ Flash 2 – the best, the safest and the most convenient way to update BIOS.

Revised February 4, 2010.

Updating BIOS is serious business!
Every precaution should therefore be taken to prevent that anything goes wrong. Above all: DO NOT USE ASUS UPDATE!!! AFUDOS is the only good alternative to EZ Flash 2.

EZ Flash 2 is a built-in function of BIOS. It is the safest way to update BIOS, because one is not dependent on the operating system, any application, internet connection, firewall settings, antivirus or anything else that can put the vital BIOS update at risk.

On a new build, BIOS can be updated to the latest version before installation of the OS, which may possibly make the installation go smoother and safer.


Note: All what's said below about loading BIOS defaults also applies to the other BIOS update methods (ASUS Update and AFUDOS)!

The PC must never be overclocked during the BIOS update! Always load and save BIOS defaults before and after a BIOS update (press <F5>). By loading and saving BIOS defaults before the update, CPU frequency, memory frequency and voltages are set to default (Auto).
Memory timings are set to SPD values which ensure that a PC with high performance memory that need a higher voltage than 1.8V for DDR2 or 1.5V for DDR3 is able to boot on the standard Memory Voltage. Save the default settings (press <F10>) before starting the update
.

When these instructions are carefully followed, there will be no need for a CLRTC.

Preparation:


  • Document all your preferred BIOS settings (i.e. the settings you have changed from the default setting).
  • Download the BIOS file, which normally is compressed (zipped).
  • Unzip the BIOS file to a FAT/FAT32 formatted USB Flash Disk with only one partition (or to a Floppy Disk or a CD-ROM). If the unzipped BIOS file is named like e.g. 'P5B-ASUS-Deluxe-1101.ROM', you can rename it to 'P5BD1101.ROM'. Otherwise a truncated name will appear as 'P5B-AS~1.ROM' due to a limitation to max 8 characters in the filename (8.3).

Update:
  • Reboot.
  • Press (tap) <DEL> during POST (Power-On Self Test) to enter BIOS Setup.
  • Load BIOS Defaults (press <F5>).
  • Insert the USB Flash Disk containing the BIOS file P5BDxxxx.ROM. (Note that the USB Flash Disk has to be inserted before boot to enter BIOS, otherwise it won't be detected).
  • Save and Exit <F10>. (BIOS will now restart).
  • During BIOS restart, press <DEL> to enter BIOS Setup again.
  • Under Tools menu, select ASUS EZ Flash 2. It may take 20 seconds for the drives to show up. Select a drive in the left pane <Tab>. Use <Up> and <Down> arrows and <Enter> to select a drive. If you don't see the BIOS file in the right pane, check the other drives. Note that the drive letters may not be the same here as in Windows.
  • Select the BIOS file (e.g. P5BD1101.ROM) and press <Enter> to start flashing. Supervise the update, which includes the following stages: Erasing - Flashing (writing) - Verification. BIOS will automatically restart when the update is ready.
  • Disconnect the USB Flash Disk before/during the restart.
  • Perform a C.P.R. (CPU Parameter Recall) which resets the chipset. Power down, remove power cord from the PSU for 2 minutes and then power up.
  • Enter BIOS and load BIOS Defaults <F5> again.
  • Reenter your preferred BIOS settings - if you are using AHCI or RAID mode, don't forget to set 'Configure SATA as' to [AHCI / RAID]. Also remember the settings for the JMicron Controller, Audio and Memory Voltage. Check also that the Boot Device Priority is ok.
  • Save and Exit <F10> (automatic restart).
  • Press <DEL> to enter BIOS Setup and make a final check that all BIOS settings are ok. Save any changes.

I tried mixing old RAM with new and it still won't work. It only works if I use my old RAM

RAM that works: Crucial 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600)
First attempt at 16 GBs: G.SKILL Ripjaws Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1066 (PC3 8500)
Second attempt: Kingston 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600)

Only the original Crucial memory works. When i tried the other two, nothing would show on the screen.

Any help here would be awesome and much appreciated!

EDIT: I tried googling for help and found a forum post on here already on the same subject when my first attempt didn't work. That's what pointed me to buy the Kingston RAM. It was recommended by a user here and it still didn't work.



can your board use (Quad Channel Kit)? cause the (G.SKILL Ripjaws Series) are Quad.
maybe thats way there not working.

i just checked for you and your board can only use (Dual Channel kits). so you no the (G.SKILL Ripjaws Series) are not going to work. Newegg.com - ASUS M4A785TD-V EVO AM3 AMD 785G HDMI ATX AMD Motherboard.

hope that helps you.

As far as I know a RAM stick is a RAM stick. The RAM modules in a Quad Channel Kit are just a matched set of 4. The timings are a tighter spec to work together better in a quad channel system, but there is no reason you should not be able to buy two dual channel kits or 4 single sticks all of the same spec in a quad channel system. And it works in reverse: it's just 4 sticks of matching RAM.

If anyone has some documented information that counters this I'd love to see it.

Aight. I downloaded the file and unzipped it to a flashdrive. Does it matter if other stuff is on the flashdrive?

ok hear is the list of ddr1333 that will work with your mobo.

and the list of faster ram you can stick in

TVeblen you can not allways just go to a store and grab any ram you think might work in your mobo becase the newest ram might require a voltage that your older mobo cant do or atleast the bios are not set up to do. I just did the same thing with my friends pc i built because the ram i bought my friend the 1st time around did not work and after looking it up the last 2 digets on the modle number was off i needed xxxxxxxx7d (1.5v) and i bought xxxxxxxx7q (1.7v) so my friend all ram is not the same

That's good news. While your board can work with 16GB, newer BIOS updates ensure that newer styles, speeds, and brands work as expected. Very glad you got this worked out.

That's great news! Congrats!

Are you going to stay with 12GB or try and go back to the 16GB kit?
