Bios 2503 Asus Z790 Extreme - Stable Settings

[vincio]

I installed the new bios 2503 and found the perfect settings that makes every CPU 13th and 14th stable (obviously if they are already degraded you have to change the CPU). From the tests done with Cinebench and OCCT I found no problems and the scores are high.

These are the settings (remember to reset the bios to default before setting them):

Performance Preferences [ASUS Advanced OC Profile].
Ai Overclock Tuner: [XMP Tweaked]
ASUS MultiCore Enhancement: [Auto - Lets BIOS Optimize]
SVID Behavior: [Auto]
Performance Core Ratio: [AI Optimized]
Optmized AVX Frequency: [Normal Use]
Efficent Core Ratio: [AI Optimiezed]

Digi+ VRM
-> CPU Load-line Calibration: [Auto]

Internal CPU Power Management:
-> CPU Core/Cache Current limit Max: [400]
-> PL1 - Long Duration Package Power Limit: [300]
-> PL2 - Short Duration Package Power Limit: [300]
-> IA CEP: [Disabled]
-> SA CEP: [Disabled]
-> IA TDC Current Limit: [Motherboard's Capability]

Thermal Velocity Boost
-> Enhanced TVB: [Enabled].

Tweaker's Paradise.
-> UnderVolt Protection: [Enabled]

AI Features:
-> Cooler Efficiency Customize: [User Specify]
-> Cooler Score: [177]

BCLK Aware Adaptive Volgate: [Auto]
Actual VRM Core Voltage: [Auto]
Global Core SVID Voltage: [Auto]

High Dram Voltage Mode: [Enabled]

In detail I clarify that if you already get a high score for your fans, then not change the “Cooler Efficiency Customize” parameter.

While on the recommended settings this should be specified:

- Enhanced TVB: prevents the CPU from reaching high clock speeds if it gets too hot, I recommend putting it on ACTIVE.
- UnderVolt Protection: is part of the microcode resolution, prevents the processor from going under minimum voltage, recommended to put it on ACTIVE.
- CPU Core/Cache Current limit Max: limits Amper and it is recommended not to leave it on auto but set it to 400A.
- PL1 and PL2 manage the maximum wattage of the CPU PL1 is the maximum wattage, while PL2 is the peak inrush, both you can keep them at 300w

As for the other parameters:

- ASUS MultiCore Enhancement: manages the scenario for multicore, I always recommend leaving it on AUTO.
- SVID Behavior: manages the Load Line (AC) scenario, I recommend AUTO so the system decides the best scenario.
- BCLK Aware Adaptive Volgate: adjusts CPU voltage with frequency curves when overclocking BCLK - suggested to leave it in AUTO or alternatively OFF.
- Actual VRM Core Voltage: regulates and decreases the input voltage to the CPU, if set manually it becomes a fixed and constant voltage; this parameter if used, should be changed on its own, while Global Core and Cache Svid in this case should remain on AUTO.
- Global Core Svid Voltage: This works on idle and full load L1 and L2 loads but with no priority on cache or cpu data, so as if it were a core curve, this parameter should generally be undervolted from -0.050 to -0.100 and if used , I recommend using Actual VRM and Cache Core Svid on AUTO, however after the latest BIOS 2503, as suggested now, it can be left on AUTO.
- Cache Svid Voltage: Works on L3 voltage and is used to prioritize cache processes; this parameter should always be left on AUTO because if set manually it causes bottlenecks with CPU overheating and BSOD system.
- IA / SA CEP: CEP is a processor integrated detector that senses when the Processor load current exceeds a preset threshold by monitoring for a Processor power domain voltage droop at the Processor power domain IMVPVR sense point, disable CEP may increase performance.

ok friend, you are right!

I'm waiting for your photos with 4 sticks of 1.4v ram and mhz raised to 7200.

Hi,

I have been reading this message chain and am not sure how to respond.

Basically, I have my 4x48GB 192GB Corsair Vengeance DDR5 running at XMP II 5200 mt/s 1.25v and the memory controller set at 1.35v, System agent at 1.25v, and IVR transmitter (?) set to 1.25v as well.  This seemed to be the only way I could get it to POST, and I did not enable high DRAM voltage option.

I currently want this much RAM, although I am not sure why.  I don't play games much but want to start again.

I currently have ICCMax set to 400amps and Pl1/Pl2 set to 300,320 watts respectively.  

I have TVB, eTVB, TVB voltage optimizations and overclocking TVB enabled with CEP disabled. I have maximum core temp set to 110C and other settings I can't currently remember. 

My core frequencies ratios are:  p-cores 62,62,62,59,59,59,59,59, e-cores 46,45.

My benchmarks are now pretty good, and I am satisfied at the moment, but would love it if I could do better:

If there is something I can provide or add, please let me know.

Thanks for all your comments.

Well, the scores already seem very good to me. I was wondering and I ask you, what do you do with 4 ram for a total of 192gb?

That is, how do you usually use your computer and why do you need so much gb of ram?

[jbmerrill1954]

I forgot to tell you that I have been working on further tuning since my first post.  That is why my scores increased.  However, my system is still unstable as it crashed a little while ago.  I have since changed the SVID behavior from auto to Intel fail safe which has significantly raised the core voltage. I am trying a small undervolt but I don't think it is helping much and I am leery that if I make it larger, it will cause instability.   I am trying to figure out how to proceed from here now.  Any thoughts on the core voltage?

[vincio]

I remain of my opinion, that is, if you respect the settings that I suggested you have no problems and the instability problem that you encounter is to be found in the ram. Considering that you have had other crash episodes, I would do two tests, the first is to enter the bios and start MEMtest86 all night. If you encounter errors, then use only 2 sticks of ram, enable XMP, High Dram Voltage, use the maximum OC frequency supported for your ram and set PMIC Voltage to Sync All and finally repeat the test with MEMtest86.

[jbmerrill1954]

Hello,

I think you are absolutely right.  I have been fighting with my memory again.  I have tried several settings and do run memtest86 each time for a while to check for errors.   I will look over your settings again and try to apply any differences.  I have some G.skill ram kits that I was thinking about falling back to and may have to try those.  They are smaller capacity and higher speed.

Also, I have changed the SVID behavior to 'training' and I think that has helped a lot.

Thank you very much for your replies and helpful advice.

[vincio]

I personally wouldn't use SVID Behavior during training, but would always leave it on AUTO. Because as mentioned, it handles the A/C load line values.

Best case: 0.01mOhm
Typical (stock): 0.50mOhm for 13900k, 0.80mOhm for 12900k
Worst case: (I could be wrong) 1.10mOhm

I recommend using the v/f point offset for undervolting instead.
You will be able to undervolt your all-core turbos (e.g. 51x, 54x, and 57x multiplier points) to greatly reduce power draw while keeping idle and boost stable at stock voltages.

Or, alternatively, without using V/F offsets, set the CPU load line to high values. For example, if you have it on Auto and it reads CPU load line 3, set it to 4 or 5

[swale]

I always set a maximum CPU temperature for safety. I use 80C which still gives a Cinebench score 95% of the typical score for my i5-13700K CPU.

[vincio]

Small update to the initial settings that I recommended, I changed "Maximum CPU Core Temperature" from Auto to 105 degrees, now I limit the throttling and the performance has further increased.

I would say not bad for a 13900K, I attach the score screenshot, I went from 37.500/38.000 to 39.500

Vincio i have a asus 790-f can i still use your settings you posted i9 14900k
