Help on overclocking 7700k

[jeffrey1289]

I've been running x264 16 Threads for 10hrs and this is the info read in hwmonitor. Is it means it's stable? Can I go ahead and go for higher clock? Also why does the clock speed in hwmonitor read is 4694 when I dial 47 in bios?

The BLCK may not be exactly 100.00MHz but 99.xx that is why you see 4690MHz instead of 4700MHz.

Temps are fine, you can probably go higher with more voltage, although for only 75W of heat, you must have a pretty mediocre cooler.

 

4694 is close enough to 4.7Ghz. it's just margin of error. might be your monitoring software, or BCLK being at 99.9

You're the only one that can answer that question bud.  If the overclock is stable for the load scenarios that you place on your CPU, that's all that matters.

How far you think I can go?

The 4690 is close enough to 4.7 but it MIGHT be because of windows power management (power options) settings. Make sure the max processor state and min are 100 when bench-marking and stress testing  and the max is 100 and the min is , well whatever you want it idle to  (edit) save power when NOT testing. I have mine set to 0 min 100 max.

 

4.7 at 1.266 volts isn't bad. Try 4.8 at the same and run Aida64 for a few hours and see if it A. throttles B. crashes. If not great. If it throttles consider a better cooling solution. If it does not throttle but crashes, add volts. try 1.3 thats what mine worked at. However, I backed it to stock because A. I saw very little gains in most games and even video editing and B. its hot as a mofo where I live now and my thermal headroom shrunk using a h100i v2.

Mostly i'm gonna do games for like ~8hrs. And the rest of the time probably just browsing and stuff. Sometimes will just leave it on for 24/7 for like one or two days

Then get started on some gaming.  If you experience any issues, dial in a bit more VCore and retry.  If you don't, you'r perfectly fine.  Enjoy the build man!

depends on your cooling solution, and on your chip.

 

if you were on water, you could reach 5Ghz or maybe even 5.1 or 5.2 if you're really lucky.

maybe you can go for 4.8 before hitting thermal limits.

if you get a better cooler, maybe 4.9 or 5Ghz

nah.

"gaming stable" isn't really a thing

I'd suggest a full on stress test for a few hours before deciding on the final overclock. then when you move to gaming, you know that your CPU is easily stable.

I got the corsair h110i. Also, after I go further is there any other stress test I can run for shorter that probably indicate it's stable? like an hour or so?

Realbench and aida64

I've been running x264 for 10hrs haha lol

For some reason realbench just doesn't work. The luxmark will stop running, display crash. But my graphics doesn't have any problem when I run all other graphic stress test and benchmark. I have aida64, how long should I run for?

If realbench won't even run you MIGHT have an issue right now. Aida64...as long as you want. I say at LEAST 4 hours but that is one persons opinion. If you game for 8 hours continuously run it for 8 hours.

Thanks bud, but I'm more then experienced with achieving stability with all different types of load.   

 

While "gaming stable" as you call it isn't a thing, testing the stability of your overclock with loads commensurate with those that you'll actually be using day in and day out is a "thing".  Running any one stress test for hours does nothing for guaranteeing you stability in any task.  

 

If you want to ensure that your CPU overclock is stable for rendering.  Do a lot of rendering to test it.

 

For gaming, do a lot of gaming to test it. 

 

You get the idea.  

 

Below is my 7700k having run 8 hours of RealBench stress test at 5.3 GHz.  Even after that, it can still crash with certain types of workloads.

Well it will run, but not long. The luxmark will just have problems everytime. And I tried it on three graphic cards and it's the same.

Have you OC your RAM? or VRAM? It SHOULD finish if its stable. Also for gaming run 3DMark!. It stresses CPU and GPU and is a great way to see if the 2 OC will play nice

I ran 3DMark. It passes easily, nothing goes wrong. I did xmp before, but that leads to like very high temps. I know that because after disabling xmp I dropped almost 10c in temps.

[jeffrey1289]

And I did run realbench fail when xmp was on....okay...i probably should run realbench without it...

If you are having continued problems with Luxmark crashing, delete the RealBench that you currently have and download a fresh copy.  If the problem persists with the new copy, you'll need to add VCore to resolve the issue.  

 

There are known issues with RealBench when run in SLI mode, but I'm not sure that this applies to you.  For those that run SLI, disabling SLI may stop the Luxmark issue. 

 

Otherwise, if it continues, your CPU is not stable for that type of load.

I see...thx...
So what are the max temps that I should keep it below when running realbench and aida64?
