The laptop started up with a bar that did not match the specifications. What consequences?

Question

Iron

Why this happened is not so important.
There was a laptop. there was a bar on the PC3-12800 They
set the bar with the PC3-10600.
Starting the laptop - everything went except the screen.
Because in this case, 0 thought only that the bridge burned down. southern northern, here is not in the know.
In general, I call the ironworkers to account, because I still have to carry it in for repairs tomorrow, but I would like to know what happened.

Answer 1

Kind.
Well, as if the fact that you set the memory to a lower frequency should not have burned the laptop. Memory would work at a reduced frequency and that's it. The only assumption is that they did not install it correctly or they hit it with static during installation, they forgot to remove the battery, etc.
If you remove all the memory strips, does the laptop "beep"?
