Not possible to exceed 3.9GHz for this i5-6600K processor.
Not possible to exceed 3.9GHz for this i5-6600K processor.
Hello,
According to the title, I am unable to exceed an overclock limit of 39. Each time I press enter after entering 40 for a 4.0 GHz setting, it reverts back to the default value of 35.
Until reaching 39, I increased the value by 1 and performed stress tests using prime95; results were normal and temperatures stayed below 55 degrees Celsius.
Of course, this is my first attempt at overclocking.
I tried turning off Intel Turbo Boost, but that didn’t help. Disabling C-states also didn’t yield any improvement since I only had nine available profiles.
I also attempted to disable the XMP profile, but it wasn’t present in my BIOS—possibly because of outdated memory.
Mobo: Gigabyte GA-B150M-HD3
RAM: 2x 8GB DDR3 1333GHz
PSU: 700 watt
GPU: 1060 gtx (considered overkill)
I also tried manually increasing my RAM speed to 1400 MHz, but that didn’t work either.
I’m wondering if my old motherboard and RAM were the main constraints here.
Lastly, I considered the CPU voltage setting, which is currently at auto 1.215 volts.
I don’t see any issues since temperatures remained stable and the system didn’t crash. Even when I increased it by 0.01, no improvement was observed.
It would be great to get a clear answer soon—whether I can surpass 40 or if an upgrade is necessary sooner than expected.
Thanks in advance!
Your options are going to be pretty limited if you want a Z170 board that supports DDR3.
I'll mention that officially, according to Intel, Skylake only supports DDR3L (1.35V) and running regular 1.5V RAM can cause damage to the memory controller over time. Whether that's a genuine risk or they're just covering their butts, I couldn't say.
Overclocking isn't possible on your motherboard; you require a Z170 or Z270 board to achieve it.
Would an ASUS Z170-A function properly then? Also, thank you for your response.
Along with how in the world you have multiplier options unlocked on that motherboard, I would also want to know how in the world you are using DDR3 with a skylake CPU?
And any Z170 motherboard will workfine, but you need DDR4 ram not DDR3
I don't understand the unlocked overclocking for my motherboard, but I'm sure you're aware that the 6600k works with DDR3. Also, your question has already been addressed, thanks!
Well if for some reason the board you're using has an unlocked multiplier for your CPU and supports overclocking, there are a few possibilities:
1: it's the maximum the board can handle and a Z170 will resolve that.
2: it's the maximum your CPU can reach, and you didn't get lucky with the chip design.
3: you haven't adjusted your voltage at all, and the highest it will go is at the current setting; you'll need to increase it to reach 4ghz or higher.
Or option 4: a mix of the above scenarios.

What are the specifics about using DDR3 with a Skylake CPU on this motherboard? And is a Z170 board sufficient, or do you need DDR4 RAM instead?
If the board supports an unlocked multiplier and overclocking, here are possible reasons:
1: The board's maximum limit; a Z170 should handle it.
2: Your CPU's maximum limit; you might not have the right chip.
3: You haven't adjusted the voltage at all; increasing it could help reach higher speeds.
Or it could be a mix of these factors.
The issue is that your motherboard can't be overclocked, and it's not related to voltage.
