HELP with OC!!!

[t.bender94]

Hello, 

I'm trying to OC my 7700k. I got it running at 4,9 Ghz at 1,315v. The temps are low 80 while benchmarking with cinebench and aida64. 

My MB is the MSI M% Z270 and the cooler is the silent loop 280mm. Idle temp is a little bit under 40. 

Shouldn't I at least get 5Ghz with that cooler? What can I do to get there? With 5 GHz (1.340) I got I running for a day but then blue screens started to appear.

have you messed with voltage? low voltage=less fire

Silicon is known to be a lottery exactly because there is no safe standard on overclocking capabilities, some get to go farther, others not that much, I honestly think that yours on 4,9ghz stable as it is already is a good jackpot, 5ghz might look cooler on the screen but if it gives you blue screens it is a certain no go.

I bought six 7700k CPUs at one time and every one of them with the exception of one would do 5 GHz or better with a H115i AIO used in my testing configuration.   Voltage requirements on all of them were 1.25v to 1.29v to pass HWBOTx265 and much lower than that to run AIDA64 for an hour.

 

One of the 6 was a turd in the cache department and couldn't go any higher than 4.5 GHz somewhat stable and wouldn't even boot if it was pushed much higher.  If you are running a 1:1 cache, you may want to try running at stock to rule that out.

 

On my Asus board at higher clock speeds (5.3 GHz to 5.4 GHz), VCCSA and VCCIO were running high when left on auto and it impacted stability.  Dialing those down took care of things. 

 

While temperatures do influence voltage requirements, your voltage is pretty damn high for that clock speed.  You may very well have a dud.  

 

Can you be more specific about your OC?  Cache and mem settings?

I'm pretty new to overclocking so I didn't change much.

But when I run the CPU at 1,315 volts at 5Ghz I get the blue screen while using cinebench. So I guess it is too low? Or do I just have to change something else?

What is your cache and memory set to?

I'm using xmp. The memory runs at 3200Mhz and the cache settings are standard I guess. 

Should i try to take a picture of my bios settings?

Turn XMP off until you have determined your CPU overclock by itself.  Leave cache set to auto and try rerun Cinebench at around 1.25v.

Ok, i'll try that.

I tried your suggestions and the system wouldn't even boot until 1,300 volts. It then crashed immediately. So I tried to go up to 1.32 again and it didn't work. Soi returned back to the old settings and cinebench is running just fine.

You're chip might just suck.  You are kinda close to thermal limits at 5 GHz anyways.  Sounds like you should fine tune 4.9 GHz and stick with it.

Yeah, I think thas what I'm left with. Pretty sad, but what can you do. Might try to reapply thermal paste. Otherwise, I'm just gonna stick with 4,9 Ghz.
