Has anyone tried these settings?

I have only changed cpu current capability to 130%, not 140!

in gaming at default, my cpu boost up to 4325 all core, with this setting my cpu boost up to 4400 all core

do you think they are safe for 3900x?


SETTINGS:
The EDC limit set to 1 really works for boosting all cores and single core to their MAX! Thanks to the guy that figured this out.

Here is what I did to get it to work
Set your ram timmings to whatever you prefer.
And the fclk to half that of your ram speed.

In extreme Tweaker/core performance boost

set it to – Auto

In extreme Tweaker/precision boost overdrive

precision boost overdrive = auto
max cpu boost clock override = auto
platform throttle limit = auto
Set all 3 options to AUTO

In extreme Tweaker/digi+ power control
cpu load-line calibration set to = LEVEL 3
cpu current capability to 140%

In advanced/amd cbs/nbio common options/xfr enhancement/accepted
precision boost overdrive = auto
and precision boost overdrive = auto


now in
advanced/amd overclocking/amd overclocking/precision boost override
precision boost override set this to -advanced
PBO limits to manual
PPT limit =0
TDC limit =0
EDC limit =1
precision boost overdrive scalar - manual =10x
max cpu boost clock override =200mhz
and the thermal throttle to =200
save and restart.

Are these settings safe?

Are these settings safe?

Defining "Safe" depends on end user. I was making these same changes in BIOS, but at least twice I had to "Accept" AMD's warning disclaimer that it could damage CPU or void warranty. That made me second-guess it and exited without saving changes.

I'd be more daring on a lower cost CPU, but not on my 3950X. DOCP is good enough for me, for now.

then why are you on overclock.net?

Lol my main concern is the Scalar setting. These chips just worry me coming from a 5820k. With that chip, I was able to get 4.4ghz for my daily usage and it ran great for 3 years with zero issues.

Are these settings safe?

I have been experimenting with those settings for some time, and I think they are safe, with one caveat:

When I set 'manual' voltage inside the AMD Overclocking panel to 1350, it caused the chip to idle at 0.900v or less, and this seemed to cause issues with system hangs in Linux. I would recommend not setting voltage there, but as per normal in the Extreme Tweaker menu. (manual voltage)

I would make some changes here to ensure vdroop on all-thread loads, such as lowering Loadline Calibration from Level 3 to Level 1 in the VRM menu. You definitely want vdroop here.

I have noticed that yes, compared to Auto (where my best CCX would only boost to 4400, tops), this will make your chip actually attain the advertised frequency when running games. However, how high it goes is highly dependent on the manual voltage you assign. For it to boost 4 threads to 4500+, or 4625 on 3 threads, it seems to need around 1.45v manual voltage. Not coincidentally, this is roughly what the board gives it when everything is set to Auto, no PBO in either menu. However, in that case, it will give it 1.45v or so and only 4 threads will hit 4400 or so for gaming, and an all-thread load (Cinebench or CPU-Z) will cause the chip to run at 4000MHz with around 1.28v. With this PBO method described, and the voltage needed for the chip to boost up past 4600 on multiple threads while gaming, under a multithread load all cores are running at 4400MHz and 1.35v. I have only tested this in CPU-Z and my temps don't go above 77c or so, but I'm pretty confident if I ran Cinebench R20 @ Realtime priority that the system would basically instantly overheat and shut off. Though it might just throttle (but PBO basically tells it not to throttle).

So, I'd say for gaming, yes this method is fine and even giving it the voltage it wants to boost above 4600 is fine, just don't run any kind of multithreaded loads, and if you do you may want to set the system to stock, use a moderate CCX ratio overclock (like 4450/4425/4325/4300 @ 1.325v on a 3900x or 3950x).

Remember that these chips are 'intelligent' and AMD themselves have basically confirmed that 1.45v~1.5v is the expected voltage required for the chip to intelligently boost four threads to 4600+. If they begin to overheat, they will lower to stay within thermal limits, before clocking back up. I would say I am somewhat concerned about these settings causing multithread loads to run at 4400mhz all core @ 1.35v- ideally, 4300mhz @1.29-ish is safe (and right now its very cold here in this room and outside so that runs around 66c during Cinebench.)

Also, I probably won't be around much, and the reason I haven't been answering questions is that I'm not feeling well again. Regards.

My Bios Settings.















Do you see things to improve ?

 

[mcbaes72]

then why are you on overclock.net?

I enjoy reading the OC success stories of others and keeping up with tech news.

 

[flyinion]

Ok - Thanks. I found those but there doesn't seem to be an option to change them ? Is there another variable I have to enable first ?

I think I just highlighted the entry and started typing the number. It's not a drop-down type selection. If that doesn't work I have no idea honestly.

Settings ?

Settings ?

Not sure what you're looking for but I only set the multiplier per ccx and changed the voltage to 1.288v.

Question: I have a different boot code showing on my Rog crosshair 8 hero every-time it boots to win 10. Computer works flawlessly and I can OC w/o errors too, boots very fast, etc. Why does it do this? BIOS 1001 (no reason for me to update) chipset is 19.10.16, newest version of windows all other drivers are up to date.

 

[mahaudi]

3950x .. all core 4400 Mhz... @ 1.280v.

What have you Guys experienced with the two VDDG Voltages?

Get well soon Neurotix. It's just not the same around here without you.

 

[newls1]

for us manual overclockers and per ccx overclockers, do we need to set EDC and the other 3 power options manually in our bios? Still trying to hunt down my insta-reboot upon doing most stress tests. Like ive said many times before, the second i try to run cb20 or ibt, the pc reboots stating "Overheat protection" which is BS, and thinking these power options may need to be set and never thought about it. 300EDC to much? and what about the other 3 options related to amps/power setup.. where should they be set at? Thanks

 

[marcelo19941]

Im not sure of running an OC with a load voltage above 1,20V, that test that indicate what is the fit voltage of my processor gave me a voltage of 1,16V

 

[neurotix]

There it is again for anyone who needs it

I hate my voice, I say um too much, and I get a lot of things wrong before showing the correct locations for them later

Needs to be remade

Neurotix,


Thank u very much !!!
