DQS training failed on previous boot

micropage7 · Feb 26, 2012

i have this day, suddenly my system got restart and then i hit this
"DQS training failed on previous boot, Revert to slower DRAM speed"
i have used the same ram for more than 2 years and its kinda weird coz so far my ram runs well
the ram setting i put on auto setting, maybe i need to set it manually and clean the contact area? :confused:

set it on manual, see if it still happens. might need a little more voltage, check the rated spec

i just figure out that it cant save any setting, all return to default setting
could be from the battery

everything runs fine
i load the default setting and re setting it again
and the new setting can be saved, weird..
but i save the current setting for now, just for preparing if it happen again

Yep, the CMOS battery is a possibility.
Boot into the bios and see if the time and date is wrong, when it happens.

Or, the bios has gotten corrupted, somehow.
A new bios flash may correct it.

Try replacing the battery... an easy task. And test.
Then move on to other possibilities.

some boards have an auto 'bad oc' feature, that reboots the system in case of an OC failure. it could be droppibg you back to 'stock' without clearing CMOS, so check in windows if your OC/custom BIOS settings have stuck.
