Question Blue screen after upgrading RAM on my Acre tower

[wuxiangjinxing]

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).

I tested both RAM and they can work perfectly fine by themselves, and in either of the two RAM slots. In other words, both the two RAMs and the two RAM slots are fine, but when I install both, the computer becomes unstable.

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.

You need to use CPU-Z-- https://www.cpuid.com/softwares/cpu-z.html to look at the parameters of the two sets of memory.
If the memory has different timings, then the motherboard might setup things so that they conflict.
You may have to buy a 16GB matched set of two DIMMs to get this to behave.

If you take the new RAM out does the PC have stability ?

I already used CPU-Z to check the two rams and they are exactly the same (I actually purchased them from the same vendor).

Also like I mentioned previously, each ram works just fine if used separately and the computer is very stable. The problem only occurs when I install both of them.

Are you running at default (2133 or2666) or zre you trying to run XMP?

I did not change anything. All what I did was installing another RAM that is identical to the original one, so I believe it is running at default. But if you could tell me how to check the running mode I can do that and give your a more reliable answer.

CPU-Z will show.
To definitely identify it as a RAM problem you need to run MEMTEST86 for 4+ hours.

I took the screenshots from all CPU-Z pages and saved them on my Gdrive at: CPU-Z screenshots. Could you please take a look and see whether you can notice any problems? Thanks.
