What's the motherboard you're using? Motherboards tend to have different types of classifying LLC levels between different manufacturers. But you're correct, LLC deals with voltages. It works by correcting what's called vdroop, which is shorthand for the voltage drop under load that you can expect to see from your inputted voltage. Usually, you want to allow for some vdroop, or enough that you can maintain your input voltage. Depending on what your motherboard sets as the LLC level, it can raise the voltage like the way you're expecting it to.

Maybe even try to get it stable with the ring at 4.6Ghz aswell and get it running at XMP?

The only single threaded bound game in that list is Arma 3. Everything else takes advantage of multiple threads (Battlefield especially), so the jump from 4.6 to 4.7 is inconsequential. See if you can lower that voltage for 4.6, 1.4v is usually what most people need for 4.7. Leave ring at auto for now, use XMP on your RAM if you haven't already. Between ring speed and RAM speed, Skylake benefits more from RAM than ring.

Then I'll go for a stable 4.6Ghz with lower voltage..


So when using 1.40v in bios and it's showing as 1.44v in HWiNFO64 under vcore, it's all just fine?

Check the Single GPU 1080P scores here

In order to see the FPS difference, either set windows power plan to Hi perf (min proc state = 100%) or disable speed step in bios.

So when using 1.40v in bios and it's showing as 1.44v in HWiNFO64 under vcore, it's all just fine?

LLC 4 to allow for a mild amount of vdroop, LLC 5 to correct it to essentially no vdroop. I use LLC 5 on a Z170-A. LLC 4 should be fine for you for now.

Well, it depends on how long it shows 1.44v. My inputted voltage is 1.355v max, so it resolves as 1.36v and the usual max is 1.376v. However, it does occasionally show 1.392v as the absolute maximum, and I've seen it upon loading some programs and such. It just depends on how long that is shown as the maximum. If its just for a short second, then that's fine, as the reading is just transitioning between the voltage levels. The sustained load voltage is what you want to be worrying about.

1.44v is just a peak. I get the same at 1.35v, maximum is showing as 1.37v.

Well, then I'll change it to LLC 4 tonight when I'm going to start lowering the voltage for 4.6Ghz smile.gif

hello everybody! i have intel i5 6600k skylake and intel stock cooler what came in i7 4790k and gigabyte z170 gaming k3. 8gb ram kingston hyperx 2133mhrz ddr4. can someone tell can i overclock this setup and how much?
post #8237 of 11372
Quick question. I have my vcore in bios set to 1.45v. When I go into windows and open HWiNFO64 where it shows CPU status, it shows a VID and its constantly fluctuating. When just sitting on desktop it bounces from 1.34 -1.39. when i run a benchmark, I see it bounce from 1.31 - 1.46 but if i averaged the #'s in my head, id say its around 1.38. Does this mean even though i have vcore set to 1.45 for the most part its running much less voltage than that through the chip? I take it thats a good thing for 4.7ghz?

You can overclock with that chip & motherboard, but a stock Intel cooler is going to severely limit you. Nobody will know how much your hardware can overclock, as it varies from one chip to the next. If you'd like to see what the rest of us have managed for comparison purposes, check out the chart in the first post on this thread. Download hwinfo64 & use it to check what temperatures you see under load stock before you start overclocking. Check the first post for in depth instructions on the actual overclocking process. You are going to want a better cooler to really be able to do much though. With a good cooler, most i5-6600K chips will do at least 4.6GHz without issue.
As for the RAM, you have a Z170 motherboard, so you have the ability to overclock RAM, but I don't know what you should expect it to be able to do in practice. I bought 3000MHz RAM, set it with the XMP profile & haven't touched it since.

thank you im really new in this oc and not so good in english i try to find some info in here. maybe i first will buy new cooler. can you say is water cooling good for oc?

Ok.. I tried 4.6Ghz @ 1.39v, change LLC to level 4.. even went with XMP active. But it didnt manage to be stable, crashed after 7 loops in the custom x264 stress test.
And now when I looked at the voltage when running it at 1.39v + LLC 4.. I had a peak at 1.39 something and current / average was about 1.37v?

The image below displays what I mean, I just started an test now with my stable 4.5Ghz @ 1.35v with custom x264 stress test.. settings: 50 loops, 16 threads, normal.
And as you can see, the current is below 1.35v? Shouldnt it be atleast 1.35v or slightly over it?
I marked Core VID just to highlight it.. but as I understood it, vcore is the one to follow. 1.32v seems to be a little to low if I want to run it with 1.35v? tongue.gif
All this is with the LLC level 4.
