do you use UEFI bios ???
for non BE overclocked to note many of RAM you have, for example:
if you raise 200 to 210 if RAM 1333 (666 cl 9-9-9-24) then it will be a 680-700 9-9-9-24 or see in CPU-Z, well this is if the ram is less voltage will affect the performance of RAM ., many tweaks that need to be tuned bro: D
if no BSOD don't change anything , and the last test your Oc use Prime95 or intelburn test software (fast result) see how high your temp if over 60C stop your OC
hwmonitor , intelburn test, prime95 that all you need download first
If heat limits are your main concern beyond the OC, you should check your motherboard settings. I have a gigabyte motherboard, I don't know about yours but mine I can set an alarm if it goes past 60 C.
Also, you are an AMD user. I don't know if I am 100% right or wrong here but I thought I would tell you anyway. I don't know about your AMD but on mine your overclock values maybe different than what you are seeing. You should download and install "AMD Overdrive". I don't want you to use this to overclock (its better to overclock in your BIOS like you've been doing). Instead, in AMD Overdrive, you will see under the "clock/voltage" tab there will be your "target speed" and "current speed". Current speed in AMD Overdrive will give you a more accurate reading of your current processor speed than CPU-Z or DXDIAG.
If you left your AMD Turbo on in the bios, you could be hitting between 3.8-4.2GHz on each core and not even know it! The thing is, it's NOT stable. In this case you will want to turn off your turbo if you haven't already. That way you can get a better stable speed on each core. Maybe you did this already but it is something AMD has (and now the intel processors as well with turbo).
