4.9 GHz at 1.31v currently, Road to 5 GHz!

post #1 of 4
Thread Starter 
Hi, I built a pc about a week ago with an i7-7700k, asus strix z270f, and trident z 3200mhz 16GB with 16-18-18-38 XMP. From 2 days, I have been running it at 4.9GHz with 1.31v, LLC7 and it has proved to be rock solid so far whether it is Aida64. wPrime or Prime96 v26.6 (custom 1344K). But looks like I can't push it further.

I have tried 1.35v to 1.39v so far for 5GHz with LLC7, it freezes in 5-15 mins of use depending on the voltage, forget about the stress tests. Seems like 4.9 is the limit of my chip.

Currently running at this config: http://valid.x86.fr/eklddz
Here is a cpuz config of 5 GHz i tried at 1.37v: http://valid.x86.fr/ux3lz8

At 1.31v my temps go upto 83C in synthetic benches, so i dont have much headroom left, but I m gonna try again with 18C cooled ambient temp in a day or two and try it at 1.4v for 5 GHz. I don't have much experience in overclokcing, actually next to none, and I have overclokced only 4790k, 6700k so far by just playing with multipliers and voltages. But this time, I have actually got interest in getting a 5 GHz clock.

So my question actually is, how does bclk overclocking? I have read some guides but I think they miss something. I tried by directly increasing the bclk to 102 MHz and keeping the memory and igpu frequencies in control, and it froze at the boot screen when I understood that i really don't know anything about bclk overclocking. I would really like to get a 5GHz stable without crossing 90C in synthetic benchmarks.

Any other suggestions to get a 5GHz stable would be appreciated!

PS: I am just an enthusiast and like overclocking, so please don't jump on me asking why would I need those extra 100 MHz.

You could try to delidd it

Delidding does mean voiding the warranty.

Once i feel that this is a reliable chip, then i will delid it, so gonna use just like it is for a month or two. If it turns out to be bad, I might just sell it and try again with a new chip.
