Need guide to OC 4790K on M7F

[DonWuLFF]

Hi, I have post for this on Z87 mobo,if that can help to describe anything.

I just change from M6F,still using H100i and change my 4790K batch,using the same setting. But before that,default bios,run Heaven benchmark,temps reach 60 and what I notice is,the core voltage reach 1.26-1.28(default bios setting,no adjust). Is that normal?
Then I tried prime95,temps 80-90,with default setting. Vcore is high as I mention earlier,then I restart and into bios,set core voltage to 1.25 and cpu core ration to 44.
Run the prime,temps still high. Re-do the bios setting,set core voltage to 1.20,temps down a bit but still in 80-90 range.

Question is,can I set lower core voltage? Any setting for me to start from?

Hurm,but my last M6F is not as high as this one.

What cpu did you have before?

[DonWuLFF]

Same,4790K. Sold the cpu and M6F,bought newest batch for 4790K.
Other things,still the same.

Do the following for me please.

1. Clear your CMOS.
2. Load the optimized defaults.
3. Reflash your BIOS to the latest version using EZ Flash or USB BIOS Flashback method.
4. Once that is done, clear your CMOS again.
5. Take a screenshot of the voltage you're seeing beside the CPU Core Voltage option.

All right,

You say your first 4790k ran cooler. How much cooler?

You reapplied the thermal paste and it didn't help at all. If your H100i is working properly as it should, this could point to intel installing the thermal compound poorly under the heat sink and die or your former cpu needed less voltage at stock settings.

If you could get your room temperature down to 70F this would help drop temps considerably.

Please do as Chino suggested and see if there are any changes in your temps.

Play Crysis will not more than 65C before. BTW,never tried the first 4790K on this board because I sell both the cpu and board with a friend of mine in the same time.

Here it is.

[Nate152]

That looks good.

Cpu idling at 35c and 1.072v for 4.0GHz.

Give crysis 3 a run again are temps any better?

[DonWuLFF]

No good. Just played COD ghost the max temp already 70. 😞

What are you using for a cpu temp monitoring program?
