My Acre desktop tower originally contains one 8GB RAM and I installed another 8GM RAM.  However, when a program (i.e., firefox) uses more than ~1.7GB of memory (tracked with task manager), it either crashes, or cause blue screen with very wird color bars in center (see the image below).

My motherboard model is Aspire XC-1660G (0x00000460 - 0x04FFCA4C) and I installed a 8GB DDR4 3200MHz PC4-25600 288 pin DESKTOP Memory Non ECC 3200 Low Density RAM.  Besides, the video card is Intel UHD 730.

Let me know if any other information can be useful, and thank you very much for your help.

    That sounds very much like the new memory stick you added is faulty. Do the problems go back away when you remove it? With two sticks installed it runs the memory in dual channel mode, and likely the failure is somewhere around the end of the first 1GB of the second stick, so would show up close to the 2GB point.

    The problem goes away when I removed the extra memory.

    Yup, then contact the vendor for the new memory and get it replaced with a working one...

    Hi @wuxiangjinxing,

    Did you update the drivers.

    Actually the problem is simpler than I thought.

    Let's say the Acre desktop is originally installed with RAM A.  I purchased two other RAM, B and C, which should be identical.

    After several rounds of trial-and-error I figured out what's the problem:

    A, B, C can all work fine if used solely.

    A + C works just fine.

    A + B, B + C will make the computer unstable.

    In other words, B is the reason of this problem.  It can work by itself but it leads to some weird problems if installed along with another RAM.

    Did you get them to replace the faulty stick?
