looking to optimize (performance+cooling) a ryzen 7800x3d system with x670e aorus pro x

[AusWolf]

Pbo with a different thermal limit - with all the issues the 7800x3d chips has faced, i feel alot more safe limiting it at 70c.

What issues have 7800X3D chips faced besides blowing up in certain Asus boards before applying the VSOC limit patch?

Wasn't just ASUS. The all could, hence the mandatory patch from AMD.

Mine never blew up in my MSi board. As far as I know, AMD didn't limit VSOC to sensible levels, but only Asus went over far enough for the chip to blow up.

My adjustments to make my 7800X3D cool and quiet:
- Applied avg -36 CO
- lowered soc voltage from 1.25v expo to 1.09v at 6000
- lowered vddp from 1.15v to 0.95v, misc from 1.1v to 1.0v, vdd18 from 1.8v to 1.6v, vddgs to 0.83v, lowered vddio from 1.35v expo to 1.24v (this voltage is related to cpu)
-applied ptm7950 on cpu, performs very close to mx6, but may never have to be reapplied

I run fclk at 2200, this requires a bit more soc voltage so that increases temps, but helps performance by a few percent.

hello there awesome community, im looking for some guidence & assistance in trying to figure out the proper way to optimize this brand new system i got, which took some time to assemble as well but it seems to be quite worth it!
so the goal here is to have good performance with good temps for the cpu without having to experience some of the issues that apparently ryzen 7000 series got with some motherboards due to some SoC voltage if i recall and i dont wanna get my new computer burned/toasted you name it.

to clarify the system:

ryzen 7800x3d
x670e aorus pro x motherboard (ended up getting this one since they had no more asrock steel legends when my brother got to microcenter)
2x16 32gb ddr5 4800 with both xmp and expo profiles to 6000mhz
thermalright phantom spirit SE 120 cooler
psu 750w gold xpg core reactor.
2 m.2 drives, 1 ssd and 1 HDD
current bios ver: F23

things ive done so far:

1. expo 1 enabled
2. pbo advance
3. pbo limits to manual: ppt limit to 85w or 85000mW
4. platform thermal throttle ctrl to manual and thermal throttle limit to 85
5. curve optimizer all cores, negative, 30

¿is this where the vcore SoC needs to mofidy in other to lower it ? it doesnt have negative values it only starts from low values till the max which is 1.30v


¿or is it in here ? im not really sure where to modify the value that im looking to lower in order to have a lower temp on the cpu and better performance overall since i know that these systems sometimes get higher volts in order to achieve certain mhz.


the settings so far ive set on PBO section


and the values under curve optimizer.

now under hwinfo yesterday i took some pictures and noticed some values which confused me:

¿why is the Vcore so high on the ITE IT8792E?, unlike the ITE IT8689E

hopefully someone can offer some kind of guidence on these values and if theres something odd to let me know as well, thanks for your time

Late to the party but here is my 2cent...

That Vcore on the ITE IT8792E sensor has nothing to do with the traditional Vcore of CPU and must be related with the CPU_VDD_18 voltage.
Any other CPU Vcore you see around its from board/VRM sensor(s) that are not so accurate.
For Zen2/3/4/5 you can rely confidently on the (SVIx TFN) sensor that gets the value straight from the CPU (AM4: SVI2 TFN/AM5: SVI3 TFN)
As HWiNFO author says, its as close to the real thing as possible.

You could set ASRock and Gigabyte to 1.5 v. Don't remember what MSI limit was before the patch. But let's continue to blame ASUS for a AMD problem.

Exactly what I was going to ask. It happened in other boards too, but once that was fixed I've only heard of a handful of cases of these CPU's blowing up, and could've been residual damage from the whole SOC voltage fiasco as some users have admitted that it could very well have been. I got my setup when that whole ordeal was going down and just kept EXPO and PBO off. Voltages were fine. Once a fix was issued I did turn them back on, made sure voltages were safe and no issues here. Definitely don't limit my CPU to 70ºC. Doesn't really go over 70 anyways, but if it does, I don't mind.

With 6000 MHz EXPO RAM, my MSi board gave it 1.35 V, which was high, but not high enough to blow it up. After the patch, it's 1.3 V on Auto. AMD didn't specify what the same limit was for sure, but only a retard would blow a CPU up with voltage, which was definitely an Asus problem.

Been reading all the comments, and as the others users has commented that is NOT your Vsoc voltage. I have noticed that for my particular mobo Gigabyte X670 Aorus Elite AX rev 1.2, I have to go into uncore Vsoc OC to be able to run the vcore any higher than 1.2 volts.

What I think is good to do with this cpu and mobo you got, is to run a negative offset PER CORE. Not all cores just the same. And to tight the ram timings which is the hardest part imo.
I run a 6000 kit CL30 rated at 6200 MT/s FCLK 2133 MHz at CL28. It's an A-DIE ram kit so It can push quite good.

The only issue I am having and can not figure out how come, is that when gaming in a hot ambient temperature room about 30 degrees Celcius. The computer underperforms compared to when the room is cold at not more than 26 degrees celcius. The difference is like night and day.

BTW this is not my final tight DDR ram timings, but I'm to lazy to test them further for now, as this is stable in prime 95 and OCCT stress tests. Haven't tried karhu or ycruncher though.

I'd love to help if anyone got any questions.
Good luck OC'ing the shite out of your 7800X3D =)

Something is thermal throttling maybe?
Did you check system temps after a game session at 30C ambient?

HWiNFO64 (sensors mode only)

yes of course! The temps are usually never exceeding 75 celcius, and therefore not thermal throttling. If I had another mobo to try it out it could be the mobo that doesn't like the higher temps.

You mean CPU temp? (Tctl/Tdie) or GPU hotspot temp?
What about GPU memory temp?

Board temps? Drive? Chipset?

Thank you very much for your comment Zach! I will look more deeply into these temps and monitor them while gaming and see if I can finalize what's going on. I already know that my cpu is not thermal throttling, but I haven't looked that deep into the gpu throttling limits like the ones you highlighted for me. Appreciate it a lot! thank you!! =)
