MSI B85-G43 with i5-4690k Overclock question

[zethes89]

In the past, most of my motherboards has come with software that automaticly finds a safe clockspeed / voltage for my cpu.

On my new rig however this has to be set manualy in bios. And im wondering if anyone has any experience with the same bios / motherboard (MSI B85-G43).

Btw i got a standalone watercooler from intel on my cpu.

Atm ive just adjusted the clock ratings in bios to 44x which gives me 4,4ghz, and my cpu runs good giving good (cold) temperatures, and gaming is great. Hovever i did not change the cpu voltage.
In a guide i saw a guy who ran the same cpu clock speeds, but put hes voltage to 1.14V or something arround that, but for me that just results in a boot crash, and i seem better off leaving the cpu voltage unset (which probably makes the bios try to set it itself?)

Should i be worryed about not setting the voltage, or is there anything i should do to further get the most out of my cpu / cooler / motherboard?

Thx

The B85 chipset is not made for OCing the CPU (doesn't work with the CPU multiplier), can get a bit of an OC by raising the BCLK, but if you want to OC by multiplier need a Z87/Z97 mobo

Is the voltage set to auto? It may be giving the CPU more voltage than you think. Any really safe overclock will need a voltage to be manually set and tested.

I would revert everything back to stock and start fresh. I would set the voltage to 1.2v and start at 4.4ghz personally. Then test it. Then I would decide whether I want a lower voltage or a higher clock and proceed according.

For a higher clock leave the voltage at 1.2v and incrementally raise the multiplier. I have had 4690k CPUs hit 4.6ghz at 1.2v with absolutely no problem.
If 4.4ghz is high enough for you dial back the voltage until you find the minimum the CPU will run flawlessly at 4.4ghz with.

This is stated a lot, but it's not true across many motherboards. My H81 motherboard in my HTPC allows you to change the multiplier.

Yes some were released with the multiplier available though Intel released an update that was to turn it off, if it's an earlier board (manufactured wise) with an early BIOS, it's possible. In general though, no. Plus not really a good idea as most don't really have a decent power phase design that will accommodate OCing the CPU

While I wouldn't recommend anyone buy a H81 / B85 board strictly for the intention of overclocking, many of these boards will. I updated my BIOS recently (Aug 2015 dated) and it still is able to change the multiplier. I'm not sure what Intel has to do with it.

As for the OP, if your chip is stable at 4.4 with no change in voltage, I wouldn't worry about it. If you are going to go further, you may want to adjust the voltage up some though.

I don't think he set this voltage at all from what it sounds like. He really should in my opinion.

I have overclocked on a B85 board as well and had absolutely no problems. It was used in a fanless (except for CPU) HTPC that was tucked between my couch and an end table.

Yes, ur correct Faktion. I havent touched the voltage at all, ive just tuned the multiplier. And it runs stable, at good temperatures. Btw is there any reasson i would want a lower voltage than 1.2v if that seems to do the trick? Would it be less strain on the cpu overall giving it a lower voltage, or is it just for consuming less electricity in general?

 

[Faktion]

Correct on both. The lower the voltage the less heat generated which is better for the part. Also the less voltage the less power is being used by the CPU. The lowest possible voltage for the overclock desired is always a good idea.

As long as you are happy with the overclock I would just stick with it. You could probably go higher but that is completely up to you!
