First time overclocking, need your advise

[Xetano]

Hi All,

 

I just recently bought a i5 8600K, Gigabyte Z370N-WiFi and a Corsair H115i to get my feet wet on overclocking.  I watched a couple of youtube videos and was able to get a mild overclock of 4.5Ghz on my 8600K.

 

I ran AIDA64 for about 15mins and here's what HWMonitor looks like after the test.

 

Should I push it even more?  From what i read, 8th gen can go up to 5.0Ghz

 

An another question is the cpu block on the H115i, how tight is too tight?  I used a screwdriver to tighten it to the point that the nuts no longer turn.

 

Thank you for your comments/advise.

Push it to 5 GHz. Just try to keep it under 1.35v

Tighten just to the point you can turn with your single hand and get tension. Don't keep tightening once you get tension.

 

Don't really have comment on the rest, but I personally save good overclocks and keep pushing until it constantly fails then start dialing back a little at a time.

Yer VRM is frying. . .

If you are talking about the one getting up into the 90s, it's getting pretty hot, but it can stand another 20-25 degrees Celsius or so.

10 before the caps will start going over spec

25 before it starts throttling.

Gigabyte Z370N is pretty garbage board actually

Eh, I honestly don't know exactly which caps it uses, but again, it is getting pretty hot. I'm curious as to why it is just the one that is getting so hot when the others aren't getting nearly that hot.

When you say "Gigabyte Z370N is pretty garbage board actually" do have this board and actually have compared it to something else?  Unfortunately this is the only mITX board available in my area.

Spend like an hour or two until you get some settings that can keep your chip stable. What cooler are you using? Did you delid?

Try AIDA64, I'm not sure if that Temp In is actually the VRMs

No, i know what VRM cmponents are on there and can calculate the stuff i need. then i compare it to others

I mean no disrespect but, how can you know exactly?  Unless you're from the factory.  

 

Now you based your previous statement that the VRM of the board is frying because you see that 90 degree c from my first screenshot.  That reading was not actually from the VRM I don't know where.  

 

I checked the SmartFan reading from the UEFI before I ran AIDA64 just to make sure that I was getting a consistent reading.  The VRM Mos reading from SmartFan before booting to windows is around 36 degree c which is consistent with the reading on another tool I used which is HWInfo64.  I also learned that TMPIN3 is not the VRM Mos temps but its the TMPIN4 reading.

 

Now I ran AIDA64 for at least 10 minutes just to see if my observation is correct, and it was.

How do i know? I know VRM stuff and can do calculations

TMPIN4 must be from the VRM, the board has some mosfes on the back, so i think the sensor is on the heatsinked mosfets and the second is from back mounted mosfet

[Xetano]

Hmmm interesting, they have the same mosfet as the Z370 Aorus Ultra Gaming that TinyTimLogan was ranting about. 

 

We'll I hope this won't die soon and I'm not planning to run 5.0Ghz on a daily basis so I hope the VRM on this board can hold up.
