First time clocker that's hit a stumbling block

[CayJ141]

At 75 years old and my first build any advice would greatly be apprecated . Over the last year and a half I put together a computer with the intent of Overclocking and hopefully on the right track . ( New parts ) Asrock z77 extreme 4 board , 16 gig DDR3 g-skill ram , Cryorig H7 , heatsink , 850 Evo SSD for boot and 1Tb. WD Black HDD for storage. Used parts , A never over clocked i5 3570k , an Evga 650 gold PSU all stuffed in a Deep Slience 1 ATX case .... Almost forgot I was using a Reven 4 eyes fan controller. Put it all together and very happy with the results .
Now time to over clock . Downloaded Core Temp , CUPID and Prime 95 and fully understand the process of Over Clockinging to fond the sweet spot . Only two areas I'm having trouble with . In a tutorial I was watching it was suggested to C/drive , properties , hardware , SSD (boot drive) , change settings and un click Enable write caching on device so if there is a crash it will not corrupt any files .
If this is true .... when the over clock is done do you go back in and click on Enable write caching ?
My other question is about Bios up dates ,,, but that can wait Any commenta on this build ... am I on the right track ? One more thing 750Ti OC game card ,
Thanks

In windows, all permanent drives have write caching enabled by default. Disabling it can result in it's lowered performance and it doesn't help any in case of a crash. Best to make full backup of system drive, Macrium Reflect is probably best for that. It's a good precaution anyway.
As far as OC is concerned, a "Sweet spot" is best frequency where it's all stable and temperatures are within parameters for that processor, chipset and VRM, that also includes acceptable voltage.
