Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Noob question, what is the setting in the BIOS that would unlock the power limit? I have a non-K 10700 and wanted to get the most performance out of it.

Hi @jbravo14 - did you have any luck with this? I am looking at this option too, compared to a 10700K, and whether removing the power levels and BCLK in the BIOS performs similarly to 10700K in MacOS.

For anyone else with a 104/6/7/900 (non-K) and adequate cooling that could test out this potential performance boost, it would be appreciated. It is essentially overwriting the PL1 and PL2 maximum wattage the chip can run at for extended periods, allowing it to stay in a boosted state, like a K chip would be doing. Relevant reading attached.

Intel Core i7-10700 Review - Way to Overclock without the K

In our Intel Core i7-10700 review, we're taking a look at one of Intel's most affordable 8-core/16-thread processors. Its low TDP of 65 W makes it power-efficient, but also limits performance. We unlocked that limit and gained up to 30% real-life performance without ever risking an unstable system.

I played around with multiple power settings in the BIOS and all resulted to the same max boost frequency of 4.6 GHz. Looking at the bios setting further, I can see that only 2 cores can boost to 4.8 GHz and the rest can only boost to 4.6 GHz.

I did see that the power going as high as 137 - 140 watts when running Cinebench by just enabling multi core enhancement in BIOS.

When Running Cinebench single thread I can see boost clock hitting 4.8 and 4.7 with multi core work load for a few cores

The only other overclock you can do is BLCK overclock setting it to 102.6 mhm for a slight boost but may be risking your NVMe drive

I guess the main benefit is that it can stay at that boosted state for an extended period of time. That is probably more valuable than the few MHz improvements (4.6GHz consistent over 8 cores is still pretty damn sweet). In any testing, did you notice it able to persist at the boosted clock speed, compared to it throttling itself after a couple of minutes and staying lower when the power limits remain at default? I haven't seen any info about that potentially impacting the NVMe - what have you seen?

And, are those PL1 and PL2 settings mentioned quite easily adjustable in the Vision D BIOS?

Apologies for the quote Yes I had it installed on USB EFI to test, and unplugged it after booting. After reverting back to the Old EFI sleep worked as expected.

Let me try the Reset NVRAM

Reset NVRAM worked! Thanks CaseySJ for the solutions!

Sleep works flawlessly now for 8+ hours since reseting NVRAM last night

I'm not that technical on the BIOS like other experts, but I did not see any specific setting for PL1 and PL2. I did try to update the thermal and power limits to the max values, but only yielded higher temps with no significant performance improvement in CInebenech.

The NVMe impact I was talking about is the Base clock overclock from 100MHz to 102.6MHz, this will bring your max boost on all cores to ~4.7+ GHz.

config.plist Changes:

• Misc --> Boot --> Picker Attributes --> 9

What does the Picker Attributes of '9' do? Was looking for documentation but couldn't find...

If the previous value was 1, then no difference will be seen. But changing it to 9 does this:

A value of either 1 or 9 shows proper disk icon labels in the OpenCore Picker.

According to my tests, Vision G haven't any PL1/PL2 limits on default settings... Turbo boost in OCCT always on max clock for 10, 15 minutes, power consumption is stable too. I think, Vision D/G always in "overclocked" mode without power limits.

Thanks jbravo. If you're able, I think the correct test here would be using Intel Power Gadget while a benchmark is running. Trying it with the thermal/power limits at both default and max. Observing whether the clock speed is staying in a boosted state more constant when thermals are at max, and seeing if it goes back down at default. Cheers.

Thanks for testing this, Ayvan. I believe the 'K' series (which I believe you own) is able to maintain itself at this constantly boosted state regardless, whereas the non-K only boosts temporarily before coming back down UNLESS we adjust the power levels.

Hi CaseySJ,
Many thanks for your excellent build guide.I have some issues with Safari, photo,user & group.
- Safari unable to load apple.com website when I select Enable JavaScript.
- Can not open photo app.
- User & group error when I click edit icon user.
Does anyone have the same issues? And how to fix it?

Many thanks.
