External RAM test point ATS - 2 errors what is it?

Question

Iron

Nowhere can I find a description and even the name of this utility. I made a bootable USB flash drive using the MultiBoot USB program; there is an item to write additional utilities. I wrote them down, ran MemTest for 4 hours. During this time, he made 5 cycles, did not find any errors. I also found an extended hardware test there, ran everything ok, except for the test in which, during the RAM test, I found two errors in the test called ATS. What is it at all I can not understand.
In general, what is the essence of the problem: the
computer reboots under load. Especially when the graphics card is under load. But even when she has a temperature of about 60 degrees, a reboot happens. There is no BSOD. Unchecked "restart computer after system failure". The syslog gives only one error:
"The system has rebooted, shutting down with errors. Possible reasons for the error are: the system stopped responding, a critical failure occurred, or an unexpected power outage."
