Question Overclocking an i5 4670k and RAM.
Hello everyone!
I recently had my i5 4670K overclocked. You can see the images here:

The pictures show the overclock reached 4.1GHz at a core voltage of 1,264VCore. Below that voltage it becomes unstable, and when I tried to push it even further, it would often crash after some time (even with higher voltage). My question is whether this issue is due to the silicon quality or if the old thermal compound in the CPU is causing the problem. Is it possible to overclock it even more?
Additionally, I also overclocked my RAM:

I can push it higher with that RAM, although I know it's not ideal to use two different sticks and it might not be safe.
Here are the specs:
Intel Core i5 4670K @ 4.1GHz
MSI Z87-G43 Gaming
G.SKILL Ripjaws 2x4GB 1600MHz CL9 + HyperX Fury 2x4GB 1866MHz CL10
My recollection overclocking old gen processors like yours is that you need to leave ram at stock speeds.
There are just too much interaction to try both.
Initially I checked the CPU usage and found the highest value achievable.
I'm successfully overclocking my 4670K at 4.3GHz on 1.250V without any issues. I can push it up to 4.5GHz at 1.300V, but I tend to keep the voltage lower to minimize electro-migration effects. Your CPU and chip selection might be less ideal, as you're using 4 x 4GB DIMMs at 1600MHz.
use prime95 to identify the source of the issue. overclock each core in the multiplier and examine for unstable cores. also attempt to overclock the ring bus, increase the frequency, and adjust the clock frequency. sometimes because the CPU runs too fast, the system can't maintain stability, or you may need to downgrade the BIOS to enable overclocking on lower-end models like i5 with the latest microcode. intel might intervene to prevent overclocking on lower-end processors such as i5 using the newest microcode. suggest command rate 1 is faster
