Hello I bought 2 RAMs of DDR3 4GB to upgrade it from two 2GB DDR3. I inserted and everything is okay so far but when I ran Memtest86 to see if I had any errors I got 640+ errors :heink:  .

And both the RAM has same manufacturer (TwinMos) and everything.

So I am asking is there any proper procedure to follow to stack two RAMs? And can anyone give me some advice on how to reduce or why is these errors coming?

Here is my PC system information:

I would first see that you have the newest bios updates..looks like there been 13 for this mb.
i would use cpu-z and see what the ram is running in speed and timing. if the mb after the update has the speed set fine and the timming to what the ram is rated for. try running memtest again. if it fails see if there a voltage changes for the dram.i would bump it if it at 1.5 to 1.6 or 1.65 and see if it fails. if it does reset the voltage back and then move the ram. i would put the two larger rams in the black slots and the smaller ram in the blue. if that how they are now then put the two larger ram in the back and the two smaller ram in the front.
if the rams dont have the same timing..is one 9-9-9-24 and the other is 7-7-7-24. the faster ram may not be slowing down.

BIOS for the motherboard? right? and I am not using the 2gb RAMs any more only using the 4gbs. Is there a way to use the 2gbs as well? And you mean the larger RAMs as 4gb is larger than 2 gb?

you should put the ram is the two read slots 4g ram and rerun memtest. you should also upgraded the motherboard bios..there are some bug fixes.
