ill use this thread to collect some new test bioses for the boards, maybe also to explain some less understood options

to disable cores ccd go here and choose ccd xx bit map down core.
each ones stand for an enabled core
best to disable from the back, ie:
110000
instead of 0011000
after selection press downcore apply changes or discard if made mistake

ocpak/octools

explanation of segment2 Loadline:

customize a heterogenous loadline for a dual segment workload range.

example above shows loadline=L6 when current is in range of 0~40A, and Level4 when current is above 40A.

 

 

 


Adds for x3d

dynamic ccd priority switch with core flex, os / driver agnostic so win10 win11 ok

97403

97404

Algo as follows:
If condition reached and ccd0 specified, then check current mem/cache activity > threshold and hysteresis reached, if fulfilled then switch
If condition reached and ccd1 specified, then check current mem/cache activity <=threshold and hysteresis reached,, if fulfilled then switch
Default hysteresis =4

Can combine multiple algos for ccd priority so combinations are wide

works on non x3d too but of course senseless on it. detailed explanation here.

I just jumped from my stable 1602 straight to 1802. No USB problems, no NVMe problems, no Sleep problems and it seems stable for now and along the testing I did up to this point.

Loaded optimized defaults, rebooted, updated to 1802, loaded X3D preset and started testing CPU-Z with different settings. I didn't load old CMO files. Instead I did everything from scratch.

  • X3D: 14400 / 706
  • X3D + EXPO I: 14400 / 689
  • X3D + EXPO I + PBO Level 1 (90C) + MLB Auto: 14800 / 697
  • X3D + EXPO I + PBO Level 1 (90C) + MLB Auto + VRM (CPU LLC Level 5, CPU VRM Switching Freq. Manual / 750KHz, CPU Power Duty + Phase both to Extreme, VDDSOC and DRAM Power Phase both to Extreme): 14400 / 645
  • X3D + EXPO I + PBO Level 1 (90C) + MLB Auto: 14800 / 691
  • X3D + EXPO I + PBO Level 1 (90C) Medium Load Boostit Disabled: 14800 / 693
  • X3D + EXPO I + PBO Level 2 (80C) Medium Load Boostit Disabled: 14500 / 692
  • X3D + EXPO I + PBO Level 3 (70C) Medium Load Boostit Disabled: 13900 / 692
  • X3D + EXPO I + PBO Level 3 (70C) Medium Load Boostit Disabled + CO -10 on cores 8-16: 13850 / 681
  • X3D + EXPO Tweaked + PBO Level 3 (70C) Medium Load Boostit Disabled + CO -10 on cores 8-16: 13750 / 679

The only difference I see between EXPO I and EXPO Tweaked is tREFI (11677 / 3892.333ns vs 65535 / 21845.001 ns). I thought EXPO Tweaked should provide the best timings / lowest latencies?
Didn't try EXPO II or NITRO at all.

Pretty sure there's a lot more I could play with. 

7950X3D | X670E Extreme | 4x16GB DDR5-6000 G.Skill Trident Z (F5-6000J3238F16G) @ 32-38-38-96-146 | 2x 2TB SSD's in Gen-Z + 1x 2TB on M2_1, all of them Samsung

Other non-default settings:

  • Memory Context Restore: Enabled
  • Global C-State Control: Disabled
  • iGPU: Disabled
  • Intel LAN: Disabled
  • Power Supply Idle Control: Typical Current Idle
  • CPU PCIE ASPM Mode Control: Disabled
  • Everything else Default/Auto

CPU-Z & CB scores are back to BIOS 1202/1602 performance. Around 500-1000 points lost on multicore compared to 1412 and 1415 which were the fastest versions for me.

@72CZR, I've observed that the Optimized memory profile does not affect CL. Additionally, there's a memory profile within the memory settings page that I could load, but it increases my memory voltage from 1.35V to 1.45V. My system is stable at 8000 MHz with 1.35V, as verified on the Qualified Vendor List (QVL) before purchase: https://rog.asus.com/motherboards/rog-crosshair/rog-crosshair-x670e-gene-model/helpdesk_qvl_memory/

@74lobster, I suggest watching this video, which focuses on the 7800x3d, though I have a 7950X. It provides valuable insights into various overclocking methods: https://youtu.be/90UBUq1mLGY?si=EIgNgaPfHCyzWUGF

I employ OC Strategy #3 at 14:44 from the same video: https://youtu.be/90UBUq1mLGY?si=SFIlyh5rqWsDzMAE&t=883. While manual overclocking yields quicker results in SuperPI, it is time-consuming. If pursued, enabling the asynchronous setting is crucial. Adjusting the correct MHz in the BIOS is also important. This manual OC may only work with mainboards featuring an external clock generator, requiring asynchronous settings to run certain components on their own frequency.

Curve optimizer reduces voltage, decreasing heat and enhancing out-of-the-box performance. However, excessive adjustment can reduce performance, even with apparent boosts. Not all CPUs support an all-core -15 curve optimizer; Ryzen Master suggested -29 on all cores except one at -43. Considering the offset I add to my curve PBO, I opted for a slightly safer margin.

Load line calibration is set to level 5 to counter the voltage drop from the curve optimizer. If stability testing is not preferred, using PBO and experimenting with the curve optimizer may suffice. Gradual optimization, starting from -10 and progressing based on stability, is recommended. The gains tend to diminish beyond -15.

For proper stability testing, use https://github.com/sp00n/corecycler, testing one core at a time. Keep in mind to optimize one element at a time to identify the source of instability. After enabling PBO and memory profiles, conduct stability tests before further optimization.

Overclocking yields modest performance gains and is more of a hobby. It's essential to conduct stability tests to avoid unexpected crashes. Depending on available time, one can choose between thorough stability tests or experimenting with new settings and monitoring for stability.

If you say "loaded X3D profile"
do you mean the OC profile or the Core Flex  stuff?

@72CZR 

Thanks for the response.
But got one additional question regarding that.

If you use the Core Flex X3D preset...do you also use the Xbox Game Bar which normally switches games to the X3D cores or do you have it not installed?

I don't have it installed and I think the preset covers more possible scenarios, or I'm thinking that it should...

I think that the latency of my memory is more consistant, I dont have the best latency as I run my DRAM controller on 2000 MHz and the RAM on 4000, so I'm in Gear 2. But on Agesa 1.0.8.0 I had latency jumping 0.2+-, now it's almost rock solid, jumping 0.01+-.

I did screenshot all my bios settings, but it should be said I did load line calibration on this latest bios, I did not have that before.
So it can be that the CPU is a bit better at boosting with LLC and that gives a better/more stable latency.

But of course it's not insane differences.

Well my M2 2 TB 990pro just dissappeared with bios 1802....

had to reboot to make it visible and useable again.

Seems to be a common issue, perhaps PCIe related. I am also having a couple of AM5 SOHO servers where randomly some NVMe drives and occasionally also a PCIe attached NIC seems to disappear or reset links due to timeout. Results are a required powercycle (just warm reboot usually does not help) can revive the SSDs. The SSDs iteslf never suffered from any damage and different models like Samsung Pro 980 and 990 are affected. On one of the servers I am in a trial running the PCIe links at PCIe 3.0 for the NVMe drives. Losing some performance but stability is more important. No losses of the SSDs yet but occasional timeouts and resets on PCIe NIC.

Yes that is currently an issue. 
I downgraded back to 1801 because the missing M2 will happen sometimes with 1802.
