Checking RAM Chips on a Laptop or PC

RAM chip in a PC or laptop, though small, but plays a quite big role. RAM helps the CPU in running applications and programs, so that more smoothly its performance. But not infrequently the problem appears in RAM, and often without realizing it.

There is a case in which a PC owner adds an identical piece of RAM with two other pieces already installed in it. Unfortunately it was not long before his PC started crashing once the new RAM was used.

The owner then tries to move the new memory slice into an empty memory slot, but that just does not solve the problem. He now does not know which piece of memory is new and which is old. And he wondered if there was any way to know which part was wrong or was damaged. Do you have a similar problem?

The solution to the problem is easy. PC owners only need to provide a blank USB Flash Disk or blank CD, and also free time. When all three things are available, it's time to download the Memtest86 + program from

The program can only run in DOS environment (thus you need an empty flash disk). It offers a simple UI, which helps you check RAM conditions. What you need to do is download the Auto-installer file to a USB Flash Disk or Pre-Compiled Bootable ISO (which requires a blank CD). Choose only one of them.

  • When choosing an ISO file, use your favorite burning software to burn the file onto the CD.
  • When choosing a flash disk, you need to unpack the auto-installer download package and run its utility by selecting the flash disk to place the file. Important note: all data in the flash disk will be lost when you use it for Memtest86 +.
Boot the PC using a newly created flash disk or CD. Memtest86 + software should work automatically, but you have to wait for a while. Usually the inspection process will take several hours, depending on how much RAM capacity is installed in the PC. You have to be patient and maybe wait all night until the process is over.

The checks will be shown at the top of the screen, where you will find 'Test #x'. 'X' refers to the test number being executed. You should let the program work until the number 8 that comes out on screen.

If no errors are detected, then the problem may not be related to the RAM chip. But if there are errors that are detected, then it could be one piece of memory or even a memory slot on the motherboard is problematic.

You must find the source of the problem by selecting it. At this point, you can distinguish the memory stick from each other so as not to mix. Start with the first memory slot, and do a re-check - use Memtest86 + software - for one slot at a time, until you find one source of trouble. If more than one memory chip is problematic, then try checking by moving the chip to another memory slot.

You may also need to check the RAM chip module and make sure that the PC BIOS is configured correctly. It would be wise for you to use two or more identical memory pieces (having the same timings and specifications.)
