Basic BIOS Guide for CTR 2.1 (beta 6 and RC1)

BIOS documentation says change VDDG CCD voltage to 0,95 V - 0,975 V for all motherboards except MSI. For MSI, the suggestion is to change the VDDG IOD voltage. Is this a typographical error or are MSI owners supposed to change the CCD voltage instead? Photo of the MSI BIOS menu shows the both the VDDG CCD and VDDG IOD voltages being changed to 1.05v. Can you help me with this? Thanks.

You are a Rockstar with your Software! Fine :) But Multilingual is very Important for all User.

Nico Neumann

Hi, that's a good idea!

Yuri Bubliy

yes! RC1 friendly for anticheats

Yuri Bubliy

Hello Yuri.... Have you Interesting to make your Software Intenational? A Translation in other Languages would be very very great!!!! But @first: GERMAN :)

Hi Manjil, also 5900x + crosshair VIII Hero user here. Latest BIOS installed. Newest CTR 2.1 RC1 release just working fine for me. Have you followed each instruction step by step? Did you install the newest bios? Also just for my info: What cooler do you use?

im getting a bsod on these bios settings even with xmp off. 5900x crosshair viii hero

Hello, new patreon here. I have a Ryzen 9 5950X on an ASUS TUF Gaming X570-Pro (Wi-Fi) (latest update) and I have trouble with the guide because some things are named differently. There is no “core performance boost” setting and the core and SOC voltages are also named differently. I’ve tried to set all values accordingly but I must have done something wrong as the “after” benchmark had less points than before. It also maxes out at “just” 4250 MHz. The temperatures are at 42 degrees celsius max. Does anyone know the differences between the ASUS BIOS from the PDF and mine so that I’m confident that I’m changing the right values?

Is it just me , or it seems like this version takes 50x longer to tune, im seriously on step 31 for the first tune..i have never had it take that long O_O

I am loving the Beta6.... And I just cannot wait for the signed driver! As a few of the games using Easy Anti Cheat just killed the game processes in a few of my gaming sessions!

This is by no means a criticism in anyway, I have always been an avid supporter of your work and will always recommend CTR to anyone seeking to tweak their AMD systems. But there is a BUT ;) Firstly, I am an idiot....I liked CTR because it did all the hard work for me and greatly improved my systems,(first with a 3600X and now a 5600X,) What attracted me the most was the fact I wasn't 100% confident messing around with the BIOS settings and changing things I had no idea what they were or did, I just had to enable CTR and let it do it's thing. However, now it is getting a little more complicated for the 'average joe' user like me who is still a beginner to all this, having to change things in BIOS and other settings is taking me out of my comfort zone again, it's far easier for someone like me to go, ''oh, well I'll just set PBO 2 on in Ryzen Master and away I go!'' Again, this is no way a criticism of any kind, but I cant help but feel like CTR is getting more complicated than what it use to be. Thanks

I configured these settings on Asus Zenith II Extreme with a 3960X. Lock up during idle only....

After following these settings most games on my PC were quite laggy and I would get frame drops. After resetting my bios to default these issue were immediately fixed.

Samuel Colletti

Im having a problem where once I make the changes in the bios I cant boot and have to reflash, the DRAM light is on, (I have Asus B550 rog Strix f) RAM is set to xmp profile @ 3200mhz

Alistair Clark

Will CTR 2.1 beta 7 have the fix to anti-cheats ?

tea_m

Amazing guide. Thank you so much! Keep doing this <3

I'm curious of this too... sometimes I'll get reboots during diagnostic, or sometimes one or both tunings - and others it will be clean. It seems a lower like 2-3 llc helps my stability. Can anyone else chime in on this and whether reboots during diagnostic and/tuning matters?

Mickey85

On my Crosshair VIII Impact, there is no tangible difference between "load BIOS defaults w/ stable RAM OC" and the Asus specific optimizations. With the latter, the tuned performances of single P1/P2 profiles is slightly lower than before tuning even. Only PX then reaches a great score, but again, no different from optimized BIOS defaults. Let's see how the next build will do, fortunately Asus allows saving BIOS setting profiles ;o) PS: forgot to mention that during PX tuning, there was a reboot, but this so far happened with every build, not sure exactly why.

DeeJay

CTR didn't exist so by default is always going to be "better with mobo settings" even if that's not really true, people (casuals) will default to saying that, those are not people like us!! they don't read don't like to do troubleshooting and/or put time and work into it, so they give up and say stuff like that.

elpuertorro

Are you using the guide with Beta 5 or is there soe newer one already?

Gabriel

Just not able to get PX stable over 4900. Unsure if its worth engaging PX for that. I've got decent P1 and P2 frequencies.

Tanveer Jugpal

Amazing guide here @Riwwelorsch - I think this is finally my ticket to stability. Until now I have not been able to stabilize P1/P2 or PX.... Now I've got P1/P2/PX working all day with CTR Hybrid OC - I've been through the full battery of benchmarks, stress tests, and gaming benches and all is stable so far. I've got kind of a "meh" high bronze/low silver chip which sucks - but I am finally getting better results than my PBO + Curve settings I had dialed in before using CTR. Only I'm getting much lower temps, less power draw, and of course the ~1mv VID for idling is insanely nice. I still may try a low 1-2 LLC to see if I can push clocks up a hair more - but overall I'm within the averages you posted for the 5950X on a Dark Hero! Very happy! We'll see how it continues to perform in the coming days. Hopefully I'll remain crash-free.

Mickey85

Stability is not just stress tests and full-load scenarios. It's also quickly switching between heavy and light loads and many other factors. Of course start with the benches after tuning - but then watch some youtube videos, browse the web, do various tasks to *truly* check stability. Also with OCCT - run all of the various tests they offer. I also find Rog RealBench stress test and benchmarks will quickly show instability. It makes sense that backing it down 50mhz stabilized the tuning.

Mickey85

This is truly bizarre, but, PX recommends 4975 for high state. I ran 4975 and stressed using OCCT for over 10 mins where it went in and out of PX profile 100% stable no errors. Then I launched chrome and instant crash. Had to lower it to 4900 to stop that from happening but tried as high as 4975 with OCCT and no problems. Any idea why? Is OCCT not a good test for CTR profiles?

Tanveer Jugpal

During diagnostic it should tell you about vdroop. How high is it? And what LLC mode are you using? I am on the same motherboard

Riwwelorsch

What am I doing wrong? As above, 5900X with MSI X570 Tomahawk, 128GB 3600/CL16 Crucial Ballistix RAM and Dark Rock Pro 4 cooling. After following this guide and setting SOC voltage to 1.20V and VDDG to 0.975V, I'm getting insanely far in the diagnostics stage (827mV), with a final result of: AMD Ryzen 5900X 12-core Processor Max temperature: 61.8° Energy efficient: 5.29 Your CPU is PLATINUM SAMPLE Recomended CCX delta: 75 Theoretical maximum CCX delta: 100 Recomended values for overclocking (P1 profile): Reference voltage: 1175 mV Reference frequency: 4975 MHz Recomended values for overclocking (P2 profile): Reference voltage: 1275 mV Reference frequency: 5125 MHz Recomended values for undervolting: Reference voltage: 1000 mV Reference frequency: 4650 MHz Which sounds AMAZING. But when I try to tune using the P1 results, which requires me to up the Max frequency of course, I get a reboot straight away. Is this something to do with my RAM, maybe, which is very stable generally but not technically supported?

Thanks for the guide. Very useful.

Thank you. I've finished a run and no instant crash like before with higher values in PX. Will keep Yuri and yourself posted if I encounter any issues. Cheers.

Tanveer Jugpal

Look at Yuri's beta 6 document on page 9. 0,95 - 0,975 V is the new recommendation because its turned out 1,05 was not necessary.

Riwwelorsch

Thank you for this. I am giving it a go, now that I know where everything is for Gigabyte. I did have to do some extra digging to get to the VDDG setting. May I ask why 950 for the VDDG (i am a noob and have no idea what it does), I only ask since Yuri on one of my previous posts for Beta 3 had suggested the following. "I recommend to use SOC voltage 1.15V (this is minimum) and VDDG voltage 1.025-1.05V." I have the 5900X (silver) with X570 Aorus Master, custom loop cooling. 4 × 16 GB G Skill Neo running XMP of 3600 CL16. Cheers and thank you again. Will post updated results and stability with the new settings.

Tanveer Jugpal

The pics of the Gigabyte section were taken from a X570 Aorus Master... So it has to be there

Riwwelorsch

That's what I use. You have to set it according to your RAM oc

Riwwelorsch

Can't find curve optimiser in my X570 Aorus Master bios, I'm using the 33c version. What's my options or am I fine without it?

Hello, thanks for your time and this guide! Is not VDDG CCD a little low? My Ryzen calculator suggest that voltage to be 1.05. I have ryzen 5 5600x 2CCD and G. Skill B-Die overclocked to 3800 CL16

Much appreciated Riwwelorsch 👍

Thanks @Riwwelorsch, nice to have a straightforward guide.

You have Digi +VRM

Xdrqgol

On my Asus b550 rog strix i dont have the option “External Digi+ Power Control” any tips?

Alistair Clark

Brilliant organisation on this person’s part! Step-by-steps of where to find everything if you don’t know (like me), and succinct summary pages if you do know and just need the settings (and ofc a beginner and experienced version for each)! Excellent presentation, and glad you’ve got folks lending a hand!

Henry Curtis Pelgrift

Though remains to be seen whether that's stable. . . Not sure how to decide what to set my voltage overrides to.

Yuri, respect. it was necessary. Well done!

Максим Максимов

Wow. Following this guide on an MSI Tomahawk saw my 5900x go from Bronze to Platinum!!!

Only disabled.

Yuri Bubliy

Great Job! Yuri, will you also offer a description to implement the changes made by CTR back into Bios, so I can benefit from it, when I use Linux? The ideal solution would be a kernel driver, maybe you find a sponsor for that?

For the Asus Dark Hero, can Dynamic OC coexist with CTR or does it interfere?

This is EXCELLENT work! Almost foolproof, but some will copy your values exactly and not read anything 🤧 they have to learn the hard way.

Dizziee

1. MSI Auto will be around 4-5% Vdroop. Ignore the warning in CTR about LLC! I am sure, Yuri will remove this in the future. 2. CPU LLC and SOC LLC should be on Auto. This will guarantee the most stability. 3 VSOC 1,15-1,20 is requiered for stability of CTR in general and PX profile especially. 4. Most important point: I didn't make up these values. These are ALL Yuri's recommendations! So...

Riwwelorsch

Great summary ! Some comments: - MSI: Setting CPU LLC to Auto will be essentially no LLC and result in warning about vdroop in CTR diagnosis. LLC 3 is what I use normally. - vSOC of 1.15-1.2 is a lot and can even cause less stable operation and high temps. 1.05-1.1 is often enough, especially for 3600 or lower speeds. I would also activate some medium LLC for vSOC

Michael

Yes! That is what was missing! Many thanks man. I use similar bios settings when running my PBO curve, so it's good to see I can use them with CTR now. The only question I have is if you know what automatic in the PBO limits sections does? Cause I read that it may be best to use Motherboard for chips with 2 CCD's.

GregT

Amazing guide. Good job.
