Important! Why do we ask for this? - If your RAM sticks are set wrong, or if they are mismatching, or not supported by motherboard, your BSOD thread will grow many pages and yet you'll be having crashes. Sorting software and drivers won't help, and memtest will not necessarily detect errors.
Give us the following information,
1. CPU-Z screenshots under these tabs:
--> a)
memory --> b)
SPD as you have it in each slot, Slot #1/2/3/4/ ....
including those slots that are empty. From that we can tell if your RAM sticks are matching or not.
2. PassMark RAMMon - Identify RAM type, speed & memory timings 
3. Hardware ID tools are known to be wrong sometimes, so if you know your exact specs please tell us. Whether you know the specs or not, attach the
CPU-Z and
RamMon info.
e.g.
DDR-
Mhz,
Timing -
number-
number-
number-number,
Voltage -
RAM voltage.
You can find these specs written on your RAM sticks, RAM package, or on the RAM manufacturer's web site.
How do you set them right? - If RAM is set wrong, enter bios setup to set the DRAM options in strict accordance with manufacturer's recommendations. Often, "Auto" will do. Sometimes you'll need to set certain DRAM values manually (such as voltage), as stated by the manufacturer.
