i5 6600k Overclocking FUN
Hi everyone, I'm really enjoying pushing my i5 6600k to its limits. I have a mini-ITX build with a Corsair GTX 100i water cooler and was trying to squeeze out the best performance using an ASUS z170i Pro gaming setup.
My initial auto OC reached 4.5 with a voltage of 1.320. When it attempted to auto OC at 4.6, the voltage didn’t increase properly and the system crashed. After that, I switched to manual mode, adjusted the voltage to 1.370, and now everything is stable at 4.6.
I found out that the maximum safe voltage is around 1.52, which seems quite high even with water cooling. I’m planning to try 4.7 at 1.42 because at 1.4 it crashes and freezes a bit after logging into Windows.
I also read that some forums suggest the max OC voltage should be between 1.4 and 1.45, so 1.42 should be quite safe.
My main question is: how safe is going to be with a voltage of 1.52? Are high temperatures the only concern, or could there be other risks? Shouldn’t the system automatically shut down before damage occurs, especially since it’s far from the official spec of 1.52°C? Thanks a lot!
Guildwars2fan shared their experience and offered advice. They mentioned keeping the chip cool and suggested lowering the voltage if it's too high. They noted that at 1.4, 4.7 crashed after about half a minute, so they plan to adjust gradually from 1.41 upwards. They wished luck, appreciated the reply, and mentioned going for the water cooler to stay comfortable.

As long as you keep the chip cool everything should be fine, I think the voltage is a bit too high for the OC. Maybe try reducing it a bit.
At 1.4, 4.7 crashed after about half a minute when logging into Windows, so I’ll go slowly—1.41, 1.42... etc.
Wish me luck, thanks for the reply. Glad to hear there are no dangers except for temperature. Glad I went for the water cooler!

Silicon lottery bins are compatible with Skylake chips, operating at a maximum voltage of around 1.40. Here are their performance details:
Overclock potential at roughly 1.40v for an I5-6600K:
- 4.9% at 3%
- 4.8% at 23%
- 4.7% at 44%
- 4.6% at 85%
Using load line calibration and speedstep can lower voltage and multiplier when load is minimal.
Higher RAM speeds needing more than the standard 1.2v also affect maximum multiplier.
Skylake doesn’t rely heavily on fast RAM for performance: http://www.silentpcreview.com/article1478-page1.html
My RAM is DDR4 2400, I bought it for $70, 16 GB.
Noticed that higher clock speeds didn’t really boost FPS in games.
And as I mentioned earlier, my system would crash at 1.4.
🙁
Score around 4.7, so I think I got a decent one.
At least it doesn’t matter THAT much, my EVGA 970 SSC is clocked at 1540, (100 + 300 + /50MHz).
