Hi all,
Here is the scenario. Brand new computer. gradually it is crashing more often. I'm reading that it may be the bios memory timings need to be addressed manually.
Chipset
I'm reading some info about recalculating the timing however I don't fully get it yet. I'm also unsure how to save the bios initially in order to make changes that I can revert back too. I would rather contact the person who built it.
From CPU-Z, this is what the application is reporting:
