Problem with four sticks of RAM

Hello.

Recently I bought new computer with motherboard P7P55D-E and included 4 x 2GB RAM to fill all four slots. But my computer crashes all the time, especially when I use better programs like Lightroom or Photoshop.
Than I run memtest to see if RAM causes the problem. And I found out that RAM really causes problems. Memtest found errors when all four sticks of RAM were in slots. When I tried with only 2 slots (2x 2GB), test was succesfull without errors. Even when I put RAM in third and fourth slot. So the problem occurs only when ALL four slots are filled.
Here is the link of the ram specification:

Now, I don't know what is the problem. Is it motherboard fault or not? Is it the problem with RAM? Any advice?

How can I determine what is wrong?

Any advice apreshiated.

  1. Also to add.. I am using win 7 64bit. Windows did recognise all 4 sticks and I was using 8GB of ram. But I got those crashes all the time and people from other forums said that I should run memtest, since it can be problem with ram. So I did.

    This is the message that I got from blue screen problem:

    Problem signature:
    Problem Event Name: BlueScreen

    So please, any advice...
  2. Now I only use 2 sticks, so total of 4 GB ram. System works normally and no crashes. Even in Lightroom. Also Mozilla with multiple open tabs won't crash anymore like it did when I had all four sticks inside.

    Really aprishiate suggestions.
  3. Do your settings math the memory specs? Are they certified to work when 4 modules are installed?
  4. From the system info, there are 8GB RAM of use, yes. And even from manual of motherboard it says that supports four modules inserted into both the blue and the black slots as two pairs of dual channel memory configuration.

    :??:
  5. You failed to answer my question. What are the specs for your modules and what are the settings in the BIOS? In other words, do the settings in the BIOS match the specs?
  6. Have you tried all 4 RAM modules one by one to make certain that they are all right ?

    RAM specification says that you should be all right with all of them installed with default BIOS settings. I have a similar setup in which I have 4 RAM modules DDR3-1333 2.0GB (total 8 GB) from Kingston and Asus P7P55D with i7-860. My setup is very stable with all RAM settings at their default values in BIOS.

    If all 4 RAM modules pass memtest one by one (each module should undergo at least four hours of testing), then you may try:

    (1) updating your BIOS for better memory compatibility

    (2) increasing IMC voltage from 1.1 V to 1. 2 V in BIOS (IMC is Integrated Memory Controller in CPU)

    Hope the above helps.
