i5-4690k Overclock on H81 Mobo

MrN1ce9uy · Sep 5, 2016

Okay, so I have an MSI H81M-P33 motherboard. I didn't buy this motherboard with overclocking in mind, obviously. But I just recently upgraded from an i3-4160 to an i5-4690k because I found it so cheap, or else I would have gotten an i5-4590.

Anyways, I've tested its overclocking potential and I've reached 4.3GHz stable, but it crashes Windows at 4.4GHz after playing Battlefield 1 for only a few minutes. I was able to run Firestrike and Firestrike Ultra at 4.4GHz, but it crashes during BF1. Load temps are around 65-68C just before crash.

So to my question; is my H81 motherboard the limiting factor here? If I wanted to go higher would a better mobo allow this? Or are there some 4690k's that only get up to 4.3GHz stable?

The board is surely the limiting factor. It only has a 2+1 phase system (2 for CPU, 1 for memory) so it probably is unable to provide proper power at higher clocks.

Okay thanks. Nice to know.

What power phase should I look for in a motherboard?

*Edit: I found this that helps me understand a little more about motherboard power phase http://www.tomshardware.com/answers/id-1762454/power-phases-motherboards.html

Sorry, one more question. Would running the CPU at 4.2-4.3GHz with daily gaming be reasonable on this motherboard?

jimmysmitty · Sep 5, 2016

Well you will probably want to get a Z97/Z87 board (preferable Z97) as most of them will have much higher phases and are designed for overclocking the K series CPUs.

Do you have a budget?

jimmysmitty :

$100 if I decided to upgrade. Give or take $10.

Those are the only two within that budget for Z97.

The Z97 Fatality has 8 phases while the Z97 Extreme4 has 12. Both would be vastly better for overclocking.

I forgot to ask, what cooling are you using?

MrN1ce9uy · Sep 5, 2016

Arctic Freezer 7 Pro Rev. 2. I was thinking of getting a Hyper 212 Evo. The Arctic Freezer is very cheap and the plastic has already broken in a couple spots. I had to use some adhesive to glue it back together. :/

jimmysmitty · Sep 5, 2016

I would go for something else. The Hyper212 is meh. Phanteks or bequiet! are vastly better and have some near the same price.

MrN1ce9uy · Sep 5, 2016

Would this be quiet! Pure Rock cooler be better than the 212 Evo? http://www.newegg.com/Product/Product.aspx?Item=9SIA68V2326642

jimmysmitty · Sep 5, 2016

Slightly better and a bit cheaper.

Do you also have a limit for cooler price?

MrN1ce9uy · Sep 5, 2016

jimmysmitty :

Well, the thing is what I have now is working well for me. Anything more would be simply for enjoyment. So, I might just wait til after Christmas to upgrade again as I just bought the i5 and a GTX 1060.

Thank you for all the help though. I really like those motherboards you picked out as well as the be quiet coolers. Cheers.
