what do you recommend setting this to? any range of values?
If you aren’t overclocking and running default frequencies then “trained” SVID Behavior. If you want to overclock 200+MHz then use “typical scenario”. Don’t leave it on auto. Try both settings and check your temps. Some Asus motherboards put auto setting as worst case scenario behavior.

FYI,

There is a new Windows 11 Release Preview and it notes the follow interesting fix:

  • This update addresses an issue that affects certain CPUs. There is inconsistent reporting of the L2 cache.

I'm using the TVB +2. If i try to use typical scenario I can get some benefits? Like less termal ora less power drow? I can't really understand hao this works and if can do something for me. I only use asus Enhancement to enable remove al limits + TVB 2 steps and global svid negative to 0.0690v
 
Hard to say, i haven't gotten the chance to play with a 2x 24GB kit. My Nov. 2022 32GB A-Die kit is still chugging along happily. Are your dimm's watercooled? Personally, i would start at 1.58v VDD/VDDQ and go from there. But as i've never worked with the 2x24GB kits, use your own best judgement



Yes, 100% bump up IMC to 1.48v or higher for 8400mhz. Dont worry about degradation, highly unlikely to happen. I've been running my IMC at 1.49375v - 1.50625v for many months now with no issue. Still stable as stable can be.

I'm actually able to consistently pass VST now that i increased my IMC voltage from 1.50v to 1.50625v, and increasing IVR transmitter from 1.375v to 1.385v.

Set SA to 1.31v. Im not sure what Auto is setting SA to these days, but you'd be better off just setting it manually.

Also Set the IVR Transmitter voltage to around 1.380v-1.385v for 8400mhz
Would you have a general idea what settings I would need for a 57 stable on a 13900KS / Z790 Hero / TeamGroup DDR5 7600?
 
Question; If I get DDR5 7600 stable at 56 all cores (with whatever settings that needs) and I am bumping vcore higher to achieve a 57 all cores OC, do I need to mess with other settings related to DDR5? If not, other than vcore, what else can I adjust?
 
My 13900K/Z790 Apex/7900XTX build is done for now with a lot of custom little details. Figured I'd share - need to get back into overclocking and less tinkering haha.

Then I would probably go with "Typical Scenario" SVID Behavior setting in order to provide the most stability. Also, you might want to Disable TVB Optimisations and TVB Enhancements under the Thermal Velocity Boost category. When these are enabled or set to auto, they can actually reduce stability in my experience. Also, Instead of using the "+ 2" TVB option, instead set it to manual and input higher temperatures under each Active P-Core. For example: it will say something like "When 1 P-Core is Active: you will set Temperature A to 80c with a -1 offset and then Temp B at 98c with a -1 offset. Do this for the number of Active P-Cores from 1 through 8. Then, go back to the Advanced Tweaker Tab's main list and Set Performance Cores to "By Core Usage", then under this same category set 1 Active Performance Core Ratio to (60x for 13900ks and 58x for 13900k), 2 Active Performance Cores Ratio to (60x for 13900ks and 58x if 13900k), 3-8 Active Performance Cores Ratio to (58x for 13900ks and 56x for 13900k). Now scroll down below this Performance Core category to "Specific Performance Core" and for a 13900ks set the Two star/* P cores to 60x and for 13900k to 58x, For all the other P Core numbers for a 13900ks set to 58x and 56x for a 13900k. Save and exit. Now when there are more than 2 active cores(3-8 active), they will run at +2x above stock ratios unless they reach 80c(Temp A), then they will reduce by -1x and if they end up reaching 98c(Temp B), they will reduce another -1x, which will put it back to default Frequencies at 98c. if they were to reach 100c, then the onboard thermal monitor will reduce your ratios even further to reduce temperatures back into spec. Hope this helps and sorry I don't have some pictures of the BIOS on hand to go with these instructions. Also, If you feel your CPU core temps are always running a little too high for your liking, you can then go back into the BIOS and set Performance Cores down one more ratio for when 7-8 P cores are active.

If the official BIOS called 1203 is working well, I suggest sticking with that until any kinks are worked out of the latest Beta BIOS 1301.

When i came back home i take o look for this and make some experiments
Can i leave VCore on auto? For now I don't want to mess with him

I've flashed 1301 on my Apex and it seems no different from 1203. CPU Microcode is still 0x15. Temps and Performance is identical to 1203 for both ram and cpu overclock.
 
Thanks

Please leave “vcore” voltage on auto in all these settings for SVID Behavior “Typical Scenario” to work properly. Another trick to gain stability and dramatically reduce “vDroop” and even gain a little performance at the cost of a slight increase in heat is: under the Extreme Tweakers Tab>look for “Tweaker’s Paradise”> set “Undervolt Protection” to “enabled”. This will keep the voltage from dropping near as much under load and will actually boost benchmark scores due to the VCore getting more adequate voltage under load.

PS. I forgot to mention that when enabling Undervolt Protection it will also make it where you won’t be able to manually undervolt(negative offset on Vcore) your CPU with the option on. However, it still gains you some performance and stability. Also, under Extreme Tweaker> DIGI+ power menu> change Load Line Level to “5”. Helps again with Vdroop not being as severe.

If I got a dollar for every time someone says this after new BIOS release I'd be rich.

Zero issues here.
 
There are so many variables and settings, that its hard to make conclusions, down to hardware quality of CPU / IMC, etc

But let's say most people agree a certain BIOS version is stable, across many hardware configurations, that would be something to start with.

I think a lot of people that have memory stability issues with different BIOS updates, may not truly have a stable memory profile in the first place. Maybe you were getting by with a previous profile that was on the edge of stability, which allowed you to play games, but what you don't realize is whats going on behind the scenes. That would be file corruption in your Windows 10/11 OS and also most likely your NVIDIA GPU drivers. This is what happened to me before in the recent past. I had a game playable memory profile, but after a little time I would get file corruption on both my Windows 11 OS and my NVIDIA Drivers. Corrupt NVIDIA drivers led to eventual game crashes with "DirectX" errors. Only a new "Custom">"clean" re-installation of my NVIDIA drivers would fix the issue, but only temporarily due to the continued file corruption that will occur if you don't get your Memory Profiles "properly" stabilized. In my case use "Karhu" RAMTest, that would require roughly a 6400% coverage to be called "Stable". 6400% coverage on 16GB DDR5 modules, gives 99.41% accuracy on detection of errors. So technically, these new 24GB modules will require a higher coverage percent to reach 99% accuracy.
 
Well and it probably depends on how close to the edge of stability the OC was on the previous bios, so if there is any loss in stability with a different bios, people with a bit more, for lack of better term, "guard band" on their OC may not see a change. Voltage sweet spots might change some as well from one bios to another, so you might have to retest voltages to get back to where you were.

Having to retest with tweaked voltages of your previously stable memory profile(from the previous stable BIOS), would really suck! I'm still tweaking my 2x24GB(48GB) G.Skill 8000 MT/s CL40 XMP kit to see how low I can go on the VDD/VDDQ voltage and then remain very stable. I currently have it boot and game stable at 8267 MT/s @ 36-48-48-60 @ 1.56v @ 131,071 tREFI. After work, I'm going to try a few things some experienced users have said. One of those suggestions that worked to stabilize 8400 MT/s DDR5 kit for them, was to increase "VCCIN_AUX" voltage aka CPU Input voltage from the typical 1.8 auto to 1.95 or 2.0v. This would help accommodate higher "bumped up" IMC voltages. Second, I'm going to raise my IMC voltage from 1.45v to 1.485v. I may just keep System Agent voltage on Auto, unless it just looks too low, because this particular voltage is sensitive to too much or too little voltage, which causes crashes from what I have heard. The main thing I don't know how to do is tighten some secondary timings and all tertiary timings. I learn more and more each time I come on this forum and search through the posts on the DDR5 OC and even the Asus Strix/Maximus Z790 threads. Before I came on here I knew nothing about overclocking my CPU, DDR5 memory, or even Cache/Ring.
