I've had my i5 3570k for nearly 5 years now (in July), and it's been serving me good at 4.3GHz around 1.21v.
Over the years I've done small upgrades, new GPU, RAM and HDD/SSDs but CPU's always been the same.
I'm at that stage where I've been pushing every component of my PC (in all honesty i'm just looking for a reason to build a new PC, and so pushing my PC as much as I can until it breaks).
i5 3570k @ 4.3GHz - 1.21v
MSI GTX 970 - 1530MHz core, 2000MHz memory, custom bios - 1.275v
RAM @ 1866MHz (from original 1600MHz XMP) - 1.64v
My goal now is to push my CPU even further.
At 4.3GHz 1.21v the temperatures usually max out around 67-70 when playing demanding games such as BF1.
I've managed to get it to 4.5GHz but had to push the voltage to 1.3V and that's increased temperatures to around 77-80c. Seems stable. [BF1]
I tried to push it to 4.6 but that would blue screen until I ran it at 1.37v, the temperatures were then more around 81-83c [BF1]. I believe around 87-95c when stress testing with x264.
I want to keep pushing it more, and really not too concerned about my CPU degrading, what I'm trying to ask is how much should I keep pushing my CPU?
Would it be best that I stay under 80c when gaming and be happy with my 4.3 > 4.5 increase, or should I push it and keep temps below 90c (when gaming) and aim for 4.6/4.7GHz. From what I've read around, 80c is usually the limit.
Another thing I did notice with 4.6GHz around 1.35v is under HWiNFO I did get a fair amount of Windows Hardware Errors, when stress testing with x264, but with 4.5 @ 1.3v I wouldn't even get close to that many errors, but very very rarely got 1 (only got the error when I was running x264 & trying to do other heavy tasks (opening my chrome browser and watching TwitchTV at the same time).
Should I be concerned about this, or is this just showing the number of errors that windows could recover from and I'm not completely unstable yet but close.
I understand that I'm not really stress testing my PC the correct way, but I'd prefer to just overclock and stress test using games. If I ever do crash I know what I'll be dialing down.
Apologies for my messy post.
Thanks for your help!
