help bring a bit more power to ageing system

[SniperDude]

Have a 2500k that I have run for about 5 years lol @4GHz on stock voltage systems passed its sell by date but I don't want to upgrade just yet
so I decided to try and overclock it a bit more ( ideal would be 4.5/4.6 out my comfort zone I'm not really an overclocker)

Right now I am still at stock volts and the system is on prime95 at 4.2 Ghz.
( will leave it over night)

once I start having to adjust volts I am going to be kinda lost so any advice would be appreciated


First question I have is what temps should I be looking at the core temps or the actual CPU temp?

2500k @BeQuiet Dark rock advanced cooler
Gigabyte Z68 UD4 /8GB Corsair Vengeance
MSI Amour 1070 /Xonar Essence STX
256GB+128GB Crucial ssd /Antec P182 case
BeQuiet Dark Power Pro 650W.

Core temps are what are important. Normally the package temp is single temp that I read as it is usually the same as the hottest core.

BTW stock volts aren't really a thing. They are just auto volts - your motherboard sorta guesses how much voltage you need. Problem is that it guesses way too much causing unnecessary heat.

This was the guide I used when I started overclocking. He explains everything really well and it's based on a gigabyte board so shouldn't be too difficult to follow.

thanks, will watch that now.
