Bios update didn't raise performance to 5GHz.
Thanks a lot! IccMax was already full for the P Cache. I switched it to max for the CPU Core, but couldn’t adjust the E Cache—its slider stays locked and there’s no display in the box. However, with P Cache and CPU Core at max, nothing changed for the red EDP OTHER on Ring. It stayed constant. To hit that 50 multiplier, I needed to set a few Turbo Groups to 50 as you suggested. High Performance / Balanced, SpeedShift 0 or 128, CPU Core IccMax at 108 or 255.75 didn’t help. So yes, if that alert keeps appearing, there might still be something blocking my CPU we haven’t checked yet. What do you think?
This does not restrict your CPU core speed directly. It affects cache performance. This is likely an Alder Lake capability. When E cores are turned off in the BIOS, the P Core cache speed is capped at the P core base clock of 3.6 GHz. To verify this, disable the E cores in the BIOS—this could boost your cache speed. The RING throttling warning may also vanish when E cores are disabled.
This update seems quite unusual! Before changing the bios, I used to notice two cores consistently reaching 5GHz. It's unclear what this new bios does. I hadn't used ThrottleStop before updating, so I'm wondering if the EDP OTHER alert would have appeared then. It might be worth disabling E Cores and reverting the update to see how things change.
I was checking which monitoring tools were being used. Most options lack the precision to display the highest multiplier values. ThrottleStop offers far more detailed multiplier information than HWiNFO, etc. I recommended temporarily turning off the E cores just for testing. I was curious whether the throttling alert would disappear when those cores were disabled. That was an interesting thought. If your CPU behaved differently under an older BIOS, reverting to it could be worthwhile. The 50 multiplier appears only at the standard settings when one core is running. This situation is uncommon. It’s possible a recent Windows Update has altered the behavior so that having just one active core occurs less frequently.
I plan to test the E-core option later, though right now I’m really confused about disabling the E-cores. I’ll figure it out myself. I suspect rolling back the BIOS might be the next step. It’s possible the issue is linked to a Windows Update rather than a BIOS problem. From what I understand, my two cores previously handled 5Ghz smoothly—confirmed by HWiNFO and MSI Afterburner. I’m curious if other users with 12,700K cores have experienced similar changes recently.
Yesterday I saw EDP OTHER appearing in the Core column too. What might be happening? I just tried turning off the E-Cores. The popup from EDP OTHER is much less frequent now, though it still shows up occasionally on both Ring and Core columns—mainly yellow with only occasional red flashes. When E-Cores are disabled, my CPU never exceeds 4.9Mhz. I’m determined to figure this out!
It seems the logs indicate some performance variations based on power plans. Adjusting between 'Balanced', 'High Performance' and 'Power Saver' affected the results. Interestingly, changing to 'Power Saver' reduced the number of limitations observed. Does this align with what you expected?
I attempted to revert the BIOS settings and that didn’t fix the problem. I’ve been searching through forums without finding a clear answer. Recently, I adjusted the Performance Core Ratio in the BIOS from Auto to By Core Usage. This revealed several options ranging from 1-Core Ratio Limit to 8-Core Ratio Limit, all currently set to Auto. It seems these settings would have stayed the same if I’d kept Performance Core Ratio at Auto. In short, I didn’t make any changes, yet the system behaved differently. This is puzzling—why does tweaking those options lead to such noticeable results? Does this logic hold?
Has anyone shared their ideas on this? It looks unusual to me! Thanks.
