Any factory overclocking for Powerspec desktops?

HGS138

Hello,

I have a Powerspec G447 which has been great. Recently, a Windows update resulted in a system crash and I got a "previous overclock settings" failed error. When I loaded the default BIOS settings, I noticed it defaulted my RAM to 4800mhz although the RAM is listed at 6000mhz and the system was previously configured for 6000mhz. I imagien this was the "overclock" the system noted had failed. I then updated the memory profile in the BIOS to the correct RAM settings, and have not had the issue since, but I was wondering if there was any other overclocking the manufacturer might have done (CPU etc) in case I need to make any further updates to the BIOS. The performance seems fine but I just want to make sure that I have the same settings in place as when I purchased the PC so I am not missing out on any of my previous performance. Aside from the RAM speed, does Powerspec generally use default BIOS settings?

Thank you for your help.
