Determining Bad RAM With Memtest86

I recently updated a notebook from 4gb to 16gb, but apparently one of the new RAM chips is bad. I ran Memtest86 and it almost immediately started spitting back errors.

Is there a way to determine WHICH RAM chip is faulty from the results?

Take out all of the RAM chips except for #1. MemTest.

Take out chip #1, put in chip #2. MemTest.

Take out chip #2, put in chip #3. MemTest.

Repeat until you find the bad stick.

If all the sticks check out, Try chip #1 in slot #2. MemTest.

Repeat until you find the bad stick, or have tested each chip in each slot.

If a chip works in some slots but not others, then you probably have a damaged motherboard or CPU.

You didn't specify the laptop or RAM model, but I assume your laptop only has 2 DIMM slots. It's possible both of the new DIMMs are bad or incompatible (e.g. the laptop may not support high-density modules), or the laptop does not support 16 GB of RAM (in which case, it probably only supports 8 GB or 4 GB). Try installing one of the new sticks and one of the old sticks, and run the test again. If it works fine, swap out the new stick with the other new stick.
