Title: New RAM Trouble
Post by: casualfitzy on September 26, 2007, 08:49:47 PM
Alright, so I had 1GB (512MBx2) of RAM installed in my PC and I just put in another gig.  Now my computer says that there's 1.5GB of RAM.  CPU-Z says I have 2048 MB and Belarc Advisor says:

1536 Megabytes Installed Memory

Slot '0' has 512 MB
Slot '1' has 512 MB
Slot '2' has 512 MB
Slot '3' has 512 MB

Does anyone know where the problem lies?

Run a test :

Download the iso .... burn with poweriso at a slow speed 6x

Reboot in with disc in computer report back with any errors.....

I ran memtest and got no errors.  However, it only recognized 1536MB of RAM. GRR!!!

That's my motherboard, no onboard graphics.   :(

Main Memory
     
•    
Supports four 184-pin DDR SDRAMs up to 4GB memory size
•    Supports DDR400*/DDR333/DDR266 DDR SDRAM (*Refer to MSI recommended modules)
•    Note: PC3200 (DDR400)
Due to the High Performance Memory design, motherboards or system configurations may or may not operate smoothly at the JEDEC (Joint Electron Device Engineering Council) standard settings (BIOS Default on the motherboard) such as DDR voltage, memory speeds and memory timing. Please confirm and adjust your memory setting in the BIOS accordingly for better system stability.
Example: Kingston HyperX DDR500 PC4000 operates at 2.65V, 3-4-4-8, CL=3.
For more information about specification of high performance memory modules, please check with your Memory Manufactures for more details.
     
     DIMM Module Combination
     Install at least one DIMM module on the slots. Each DIMM slot supports up to a maximum size of 1GB. Users can install either single- or double-sided modules to meet their own needs. Please note that each DIMM can work respectively for singlechannel DDR, but there are some rules while using dual-channel DDR (Please refer to the suggested DDR population table below). Users may install memory modules of different type and density on different-channel DDR DIMMs. However, the same type and density memory modules are necessary while using dual-channel DDR, or instability may happen. Please refer to the following table for detailed dual-channel DDR. Other combination not listed below will function as single-channel DDR.
     
     
Green DIMM1 (Ch A)
   
Green DIMM2 (Ch A)
   
Purple DIMM3 (Ch B)
   
Purple DIMM4 (Ch B)

     MSI Reminds You...
     
•    Dual-channel DDR works ONLY in the 3 combinations listed in the table shown in the previous page.
•    Please select the identical memory modules to install on the dual channel, and DO NOT install three memory modules on three DIMMs, or it may cause some failure.
•    Always insert the memory modules into the GREEN slots first, and it is strongly recommended not to insert the memory modules into the PURPLE slots while the GREEN slots are left empty.
•    This mainboard DO NOT support the memory module installed with more than 18 pieces of IC (integrated circuit).
•    The Maximum memory speed decreases when the following two memory combination is selected:
- Each channel is installed with two double-sided memory module
- Both DIMM1 and DIMM3 are installed with double-sided memory module
•    Due to the South Bridge resource deployment, the system density will only be detected up to 3+ GB (not full 4GB) when each DIMM is installed with an 1GB memory module

This is from your link...i suggest consulting your manual on RAM configurations and double checking that you purchased the correct RAM.

Does your board support this much RAM?  Flash your bios, that will help.  Take a stick out and reboot, then shut down and install the stick again.
