i5-4690k Overclock on H81 Mobo
i5-4690k Overclock on H81 Mobo
You're looking at an MSI H81M-P33 board, originally intended without overclocking features. You upgraded from an i3-4160 to an i5-4690k for better performance, but encountered stability issues when running Windows at 4.4GHz after a short game session. The system crashes during Battlefield 1, with temperatures reaching around 65-68°C before the crash. Are there any factors limiting your H81 board's capability, or would a more powerful motherboard help achieve higher stability? Also, are there 4690k models that only reach 4.3GHz stable?
The board clearly sets the constraint. With just a 2+1 phase structure (two for the CPU, one for memory), it seems it can't supply adequate power at increased clock speeds.
The board is likely the main constraint. It only supports a 2+1 phase system (2 for CPU, 1 for memory), which may prevent it from delivering adequate power at higher clock speeds.

What power phase should I consider when choosing a motherboard? *Edit: I came across an article that clarifies more about motherboard power phases
Sorry, it's not advisable to run the CPU at 4.2-4.3GHz with daily gaming on this motherboard.
You should likely choose a Z97/Z87 board, especially a Z97, since most of them offer higher phases and are built for overclocking the K series CPUs. Do you have a budget? $100 would be ideal if I were planning an upgrade, with a slight flexibility of $10.
These are the sole options that fit the price range for the Z97.
The Z97 Fatality includes 8 stages, whereas the Z97 Extreme4 has 12. Both would significantly improve overclocking potential.
I didn’t mention the cooling solution you’re using.
