Help OC 13900k, Gigabyte z790 Aorus Master to 5.5ghz stable on all 8C/16T

[efsenable]

Hi guys,

I bought a PC like 6 months ago.

My only wish from the CPU & Motherboard is that the system will run at 5.5ghz constantly at a 8C/16T configuration…

I was not able to configure the system correctly, either in BIOS or Intel XTU.

 

I would really appreciate it if you could please provide me with some settings that will allow me to run the system at the desired speed.

Currently, these are the settings at IDLE:

 

 

 

 

 

 

 

 

When I run R23 – these are the clocks:

 

 

 

These are the settings in XTU I tried:

 

these are the results in 3DMARK DX12 extreme time spy:

 

As you can see, it’s a rather desperate attempt.

 

Can someone please help me out? I’m willing to pay for time consulting and assistance.

Thanks in advance.

not neccesary

 

I mean this is just a group of hobbyists that help eachother out and i really just chill on the forums to help others and just keep up/learn about new hardware cause im still stuck on ddr3

 

 

What happens if you set ratio for cores 2-7 to 55? Thatd be 5.5ghz on all cores

 

Also are your temps really hitting 105c when running cinebench? If so i dont think pushing more volt will help as youll just run into volt rollover and the cpu will destabilize if you add extra volt due to heat

 

youll need a better cooler and the 2 things that come to mind would be a massive external radiator custom loop where you hook up a car radiator to your pc for maximum cooling capacity as pc rads simply will not cut it

 

the 2nd option would be subzero phase change cooling

Literally just build a cpu block and hook it up to an ac, although in this vid seems like they were running into thermal transfer issues if the evap at -14c and cpu temp at 38c is anything to go by

 

Id totally build one of these if i had the money but haha no money atm =(  the ac units themselves are like 70-100$ used, the block just buy a slug of copper and have someone machine it for you, then theres also the brazing equipment and insulation, literally the only reason i have interest in phase change systems is just to chill my cpu and rams to subzero temps and dailying those low temps with absolutely ridicolous overclocks, quite certain you can hit 6g+ allcore if you keep temps below zero or sub ambient so theres your target and then some

My cooler is an AIO corsair h170i

It could be, but if you're overheating so badly you're overheating. You're not going to keep clocking up if you're overheating like that.

 

Either way, you probably do not need MORE voltage, considering a 13900K out the box should be something like 5.4GHz on all cores and you can get away with undervolting it more than likely. Try setting all the P cores to 55x and a -100 offset to both and see if that works

 

Worst case, you crash. Best case, your CPU works way better.

undervolting

I agree that less voltage should help keep the temperatures at a more reasonable level.

 

The screenshot posted shows an over volt instead of an undervolt. That is likely the main problem. When undervolting there should be a negative sign for the IA Offset voltage.

Oh hay unclewebb how you doing?

 

Yes this person needs to not overvolt when already overheating.

Hi,

 

What about now :

You are still using a positive voltage offset. That is not undervolting. That is over volting. Your CPU should run 100% reliably with less voltage. The extra voltage you are using is creating unnecessary heat. 

 

P core 4 and P core 5 appear to be your two best cores. That is what the star beside them in XTU means. If you are going to do individual core tuning, it makes sense to run your two best cores at the 56 multiplier. With the excess heat you have, you might want to keep things simple and just set them all to 55 or 54.  

 

Peak core temperatures of 107°C are beyond the Intel 100°C spec. For long term reliability, it is best to set the maximum CPU temperature to the default 100°C value in the BIOS.
