Dell T7600 Reliable Memory Testing Problem

I have a Dell T7600 with 512GB of memory; the memory is DDR3 PC3-14900L running at 1866 Mhz. The problem I was having was when during the boot process the system would always stop with an error message about the Dell Reliable Memory Technology (RMT) test detecting some bad memory modules and it wanted to know if I wanted those simms flagged as bad so it can continue to boot. Once I responded to this message the computer would then continue to boot. The problem was the system would hang like this every thing the computer would reboot and I would have to manually intervene in order for the computer to come up. 

At that point I ran the internal memory test to see if the memory was actually bad and after a few hours the test stated that there were no bad memory modules in the system at all. After more troubleshooting I realized that the memory I had was running at 1866 mhz and I think the system maximum was 1666 mhz which should not have been a problem since the system should just slow the memory speed down to the maximum that it can handle, but I was still having this problem at boot time.

Since I knew the memory was good I went into the BIOS and I found under the "Performance" setting, another setting which allowed the  disabling of the RMT test. I disabled RMT since I had ran that hours long memory test and it came back good.

After doing this all my boot up problems went away and everything is working and there are no memory problems either. I think what happened was that the system reduced the memory speed ok but RMT interpreted that as errors and would stop the boot process to require the manual intervention in order to proceed.
