Help me beat my Manual OC score with Undervolt and PBO!

Recommended Posts

Posted · Original PosterOP

Hi!

 

I had some questions and need some answers.
Please examine all of this and help me figure out what I should do.

 

CPU: Ryzen 7 2700x
Motherboard: Gigabyte X470 Aorus Gaming 7
BIOS version: F4g

 

Did a manual OC across all cores with: 
Vcore to 1.4V
Medium LLC
And it only helped me reach 4.1GHz.
4.2Ghz was asking for more than ~1.45-1.5V
XMP profile for ram set to Profile 1 (3600MHz)
Cinebench score - 4121 (Highest so far in my tests)
Nothing failed in prime95 test too

 

F4g is the version that has a PBO Scalar setting
It was removed from newer versions of BIOS for some reason

 

My old temps (no oc) were definitely more than this before I undervolted. They were around ~90c and idled around ~70c

 

Overvolting helped me a lot? but,
PBO is not able to push above 3999 or 4000 on load 
It pushes 4.32GHz on idle on one of the cores for some reason
Temps are definitely better
And I beat my previous 4GHz manual OC score in cinebench too

 

PBO Settings:

PBO X10
PPT 1000
TDC 114
EDC 168
vCore Offset -0.1v
MediumLLC (both) 
3600MHz XMP Profile 1 on RAM
Max Temp Reached 84.5C
Idle Temps ~50-60c
Cinebench Score - 3929

 

I've chosen the max values that Ryzen Master showed for (PPT, TDC, EDC)
I've set all of the values through BIOS.

 

The Undervolt looks pretty stable but I feel like I could do better and I'm missing a main point here.

I used 3 softwares CPU-Z, HWiNFO and Open Hardware Monitor and the readings do differ in each of them.

I've included all the pictures of after OC (load and idle) and cinebench scores
And the pictures of the BIOS settings I was talking about
Please take a look at them here:

I'm new to OC and messing with BIOS but I really like it!

So can someone please help me understand why it isn't pushing above that 4GHz or 3.9Ghz on PBO?


How can I improve the performance?

And most importantly help me beat that manual OC 4.1GHz Cinebench score!

 

Thank You!

Things I forgot to mention:

It did 4GHz stable at 1.32V with Medium LLC with manual OC

4.1GHz was only stable at 1.4V least

This may be the limit as cpu's have over voltage protection, or you just need to try small increment of voltage until it is stable

Hey I tried the manual OC

But I think PBO is pushing the limits!

So i wanted to know if there's anything I could do in setting PBO up

In the bottom left type control panel, then open it. Next click system and security, then power Options, inside you will need to click show additional plans, set it to high performance, then it should automatically run at the boost clock of upto 4.3 ghz for that cpu.

I tried that. High performance actually degraded the performance.

The default Windows 10 balanced power plan worked better.

To put it simply your cpu is most likely at it's limit

It has to handle an overclock and an xmp/dcop profile 

So first the imc just simply is at it's limit and the interconnect cannot handle and overclock and an xmp profile at the same time 

It's FCLK is really bad and im even surprised you got to this point lmao 


Fun Fact: The Meshify c is the best case to ever exist.

3100.

B550m TuF plus.

Hyper x rgb 8 gig stick. (MJR or CJR  i still don't know lol).

1650 super.

CX450.

MX500.

NX500.

Lol! For some reason the benchmarks show higher but the game performance is kind of bad (im playing at 4k so it's very noticable in some areas). Maybe I should revert back to 4.1GHz at 1.4V (Manual OC)?

Most likely yes 

Your interconnect probably wants to kill itself right now

Hey what's interconnect? 

lol i just started learning about oc and undervolting yesterday

It's a 12nm die that connects the ccxs together essentially

I've gone back to normal lol

I don't even want no overclock now

I'm scared I'll mess up my pc without knowing it
