Does the Debug display clear once the operating system begins to load?

If so then they are not errors. A debug display shows post codes, each code represents a part of the post process. If the system freezes or fails to post then a code will remain on the display, it will not change or go off unless the system is restarted, this is the only time a post code is significant. It tells you which post process failed to complete. By looking up what the code means you can then easily identify the cause of a problem.

If the codes are not clearing and you are able to enter your OS then check your Debug LED settings in the UEFI, it is probably set to "always on" or similar. Set it to auto and the post codes should clear as normal. 

The debug LED displays internal operations after post when set to always on. Many of these codes are not listed in the user manual as they are not helpful in troubleshooting issues. Basically they just tell you your system is doing something LOL

[URL=][/URL]Everything seems to be working currently but the Dr Debug keeps showing an error code of 27,28,29. The bios and windows detect 16GB of RAM and again everything seems to be working but there must be some kind of issue. I flashed the BIOS to the newest version but have not tried removing a stick of RAM.RAM is currently in A2,B2 per the mobo manual. What can I do to mske it error free?

Thank you for any advice.
Ustaio.
