Overclocking help / questions

[h4X6]

Hey all

 

first time poster here, but been around the block on forums before. 

 

For reference my set up is as follows: 

Intel I7-11700k

Corsair 240 AIO (cant remember the exact model atm)

PRIME Z590M-PLUS

Corsair 3200 CL16 DDR4

Samsung 980 pro NVME

RM850 Corsair PSU

3060

 

I have been trying to understand and just get 4.9 or 5.0 ghz on all cores for my processor. And I have a feeling i did not win the silicon lottery. Core 3 and 5, always hit 100C no matter what I do. 

 

My question tho is this... my core voltage is all over the place. I have it undervolted, yet I see it spike to 1.56 volts (rare), but mostly over 1.4-1.42 volts it will spike... most of the time it hovers within 1.3 and 1.38 (with around 30-40% utilization).

 

How the hell do i stop it from spiking to 1.5+ volts.... and how can i get those cores cooler... 

 

LIke i said the end goal would be to be 4.9 or 5.0 on all cores, without spiking the voltage and without melting my cores

 

If you could provide some assistance or at least point me in the right direct, that would be great

 

Thanks for any and all assistance!

So a couple of questions

1. What are you using to stress test? 
2. How are you undervolted? Are you using a negative voltage offset or a fixed voltage?
3. Where are you doing your overclocks? XTU or in the BIOS?

The high voltage spikes you speak of, sounds exactly like my 8700K. I totally lost the silicon lottery. I ended swapping out the IHS with a custom cobber, nickel plated one + liquid metal, to keep temps under control. 

From stock, my 8700K wants to use so much voltage. I have another friend who also have a 8700K, his at stock, with stock IHS and old thermal paste, runs cooler than mine. It's ridiculous. 

So yeah to my point, you may just have lost the silicon lottery for real, just like me. 

What I also did to keep temps under control, was to use a -Offset. I can do 0.095mV -Offset. This lowered overall temps by 5-6C on all cores.  

To futher add, if you use 4 sticks of RAM, consider changing to a kit with 2 stick. 4 stick puts more pressure on the memory controller, which also will increase temps.

1. All of them do it, the XTU benchmark, Cineplex r23, prime64, hell even running warzone will do the same. 

2. I undervolted .045 it the bios and then do further undervolting in XTU. Using an offset of - and then the number. EI: -0.045, etc etc

3. I have it set to 4.9 all cores in the bios, and then further overclock in XTU (core 0 and 1 are at 5.0, where the rest site at 4.9)

 

Thanks for the help!

Ill try the RAM stick. I have 4x 8GB sticks in there for a total of 32. So will try that and see if there are any differences. 

 

I am also debating to lap the IHS to make sure its as flat as possible, but warranty... lol

 

Thanks again for the help!

OK, try doing a static voltage instead. Voltage offsets can have some weird issues like what you're experiencing, and usually a static voltage usually allows for more stable overclocks for a given voltage value (it's for a variety of technical reasons).

 

Go into the BIOS and change the voltage mode from Offset to Static, Fixed, or whatever ASUS ends up calling it, and manually set the voltage to 1.35V, see if it's stable (at 4.9 that should be stable), and if it isn't increase it to a max of 1.4V (anything above that you'll likely have overheating issues) in ~100mV increments, checking to see if it's stable each time. If the voltage is still spiking there's something else up.

you sir, are a great help! 

 

 

Sure better then before! Thats just after 1 run, but it took about half way thru the run to hit those temps, versus, instant before. 

Might try to undervolt to 1.33 and see what happens. If all goes well, then increase to 5.0 all cores, and play with it from there

Think I got a winning combo now... 



Using prime95, as cinebench wouldnt open after a crash, and got sick of unzipping it everytime

5.0 all cores
Temps in check
1.34 volts static

But as you can see it still spiking to 1.394 volts... but thats way better then it spiking to over 1.5
