I7 8700K @ 5.0ghz

[myzzy1]

Finally finish my rig build.

Now im experimenting and benching my build, will appreciate any advice with respect to stability testing and my cinebench result.

Results:

• Cinebench @ 5.0ghz Temperature = 80 degrees on load, voltage at 1.28v

Is this temperature too high?

Can I know what PSU u using for this build?

Are ur scores around 1620-1660? If you want to go beyond 1.3V without cooking your chip under full load (not typical gamerish load), hard truth is you have to delid (void warranty).

to be frank i just wanna oc to 5.0 to play games (which is fine with pubg now)

These are my temps on load(pubg):

Is it okay? next, i wanna check if i setup my rams correctly cause they show its running at 1600 when its suppposed to be 3000mhz.

Another software, NZXT CAM shows the rams running at 3000mhz

To be honest, while your temps may stay at 80 now, over time it's gonna creep up towards 90 because the Intel TIM is crap. I went through this with my 6700k and the best thing I ever did was to delid the damn thing.

I would honestly delid it if you wanna keep your overclocks consistent over time instead of dealing with higher temps over time. Yeah delid gonna void your warranty but the amount of heat you actually cut leads to tremendous cooling which allows you to keep the system stable.

As for why your rams are running 1500 in Corsair Link and 3000 in your CAM software is that Corsair Link shows your memory as single channel speed so you have to multiply by two to get the actual running speed. Don't need to worry about that. To double check, use CPU-Z and check your memory tab to ensure it shows dual channel.

Effective ram frequency is 2x of actual. So your effective is 3000MHz no issue there.

OC guide here. Abit to read up, Kaby Lake guide but still relevant mostly the same platform with 2 more cores. Can test with something like realbench 2.56 stress test and +/- abit of vcore depending on actual use stability.

cinebench is too short , cannot show actual stability and highest temperature

I think you will hit mid 80s when using other stress test closer to real world workload and when heatsink accumulate some dust

Cinebench is too short to determine your stability of your cpu.

With that given voltages and frequency clock, I doubt that it will be stable.

Run a few more stress test applications. Blender BMW, Aida64, Intel Burn Test, Prime95. Each app you will need to run at least 3 hours each. This will then give you your true stability test and real temps instead. And I believe your temps will surge as high as 90degC.

Speed is not everything if you don't get it stable. Cinebench is just too short to tell if your cpu is running stable.

Yes I know you just wanna run games at those speed. But you will never know when it will crash. Don't let this type of moment ruin your gaming experience midway.

shows 1496 mhz again sian. So am i doing the Rams speed right? (rated at 3000mhz)

Nothing wrong with the speed. This is rated at 3000mhz. 1496mhz is correct.

Double Data Rate 1500 = 3000

In the first place, whether you are running this at 5Ghz or 4.8Ghz, in game is not going to make a huge difference. At least it will not result from a wonderful playable experience to an unplayable experience. It is not going to matter whether you are getting 200FPS vs 180FPS since you won't notice the difference unless you have the FPS counter running which is meaningless.

 

[shadey]

are you one of those who comments that the human eyes cant see more than 25fps hence 200fps is the same as 25 fps.

You have a 200hz monitor?

The 8 series Intel chips run very hot. Also check your VRM temperatures.

wow, so you are saying you can feel/see a difference when your pc runs in 4.8ghz vs 5ghz?

 

[Ferolare]

personally i'll check for stability using p95 instead

 

[elmariachi]

Intel Burn test on High or Extreme is enough to expose any flaws in overclocks and doesn't take as much time as Prime 95. Of course Prime 95 is still best for checking overclocking stability.

But prime95 avx can cook satay on top of your case

 

[BlackSmokeInTheSky]

I think prime 95 tests the system for extreme stability. my overclock fails prime 95 when it passes aida64 and is stable for my gaming and video encoding. Aida64 is good enough for me

 

[watzup_ken]

I would not go to extremes, therefore am just telling you that the difference of 200 Mhz is not going to make a huge difference. The i7 8700K runs very hot and may not be worth it to push it hard on OC.

Chip is yours, so do what you deem fit. Just a friendly heads up, so you don't have to respond in a negative way.

Same here but too bad only 1 month free trial.
