Asus A8R32-MVP Deluxe-2784 MB OK (Installed Memory Size: 4096 MB)

Hi. I've got an Asus A8R32-MVP Deluxe motherboard, and I used to have 2 CMX1024-3200C2 1 GB modules, and they ran together as 2 GB dual channel 400 MHz memoy as they are supposed to.

 

Then just lately, I installed two more CMX1024-3200C2 modules to increase my memory from 2 GB to 4 GB, and that's where I ran into some trouble.

 

My motherboard/BIOS detects the 4 Gigabytes of RAM (4096 MB), but it says only 2784 MB is "OK".

 

Here is a screenshot of my POST with 4 GB of ram (CMX1024-3200C2 x4):

You can see that the memory is set at 333 MHz even though it should be set at 400 MHz, and only 2784 MB is "OK", while the motherboard detects the full 4096 MBs.

 

Now here is a screenshot of my POST with 2 GB of ram (CMX1024-3200C2 x2):

You can see with 2 GBs, the memory is detected correctly and the speed is set at 400 MHz like it should be.

 

Any help with getting my full 4 GBs to be working/detected and clocked at 400 MHz would be appreciated. Thanks!

Justin,

I am sorry but that is normal with this MB and not seeing the full 4 Gig in Windows is also Normal.

As you add memory the memory controller will slow the memory down by default. You can try and over clock the memory and set it manually but its hit and miss as to if it will work or not.

 

Also if you are using a 32-Bit version of Windows or any 32-Bit O.S. for that matter you will only see 32-Bit of the memory no matter how much is installed.

32-Bit =

4096 Gig of memory Translated to 32-Bit

 

4096 X 8 = 32,768

The O.S. only see's 32,000 so the 768 Bits is gone off the Top then you have to subtract any other memory in your system like the memory on your Video cards and Cache on your CPU and memory used by the system for PCI caching, so 2784 MB of available memory may be normal for your specific configuration.
