News Overclocker Exposes Hack To Overclock Locked Alder Lake CPUs

[Admin]

Overclocker Der8auer discovered BCLK overclocking options for locked Alder Lake CPUs on high-end Z690 motherboards.

Fingers crossed, Intel and its partners will make the feature more accessible rather than try and sweep it under the carpet.

= disabled with the next BIOS update.

If intel would make it more accessible, would that not hurt their own K SKUs more?
Financially it make no sense to have this option (unless it remains as a gimmick for very few expensive Z boards), since they have this locked and unlocked differentiation between SKUs, not like AMD's Zen where you can OC any CPU on (almost) any motherboard and tier.

Intel likes segmentation and limitations.

The ADL K SKU has more overclocking potential than non K, mine can do 5.2 GHz on all P cores without tweaking anything except adjusting bclk ratio, everything else stock. Little bit tweaking on voltage side make it capable 5.4 GHz on all P core stable.

oh bclk. FSB overclocking used to be the only way because intel lock the multiplier on their cpu.

 

[wifiburger]

it's interesting that he found this tweak but those boards are ddr5 & too expensive for even 12900K

and why would Asus auto hide/disable the bclk generator ? makes 0 sense

Are you sure it's not up to silicon lottery?

Scenario1:
If they let non-K and K are able to OC on the same expensive MB, does it really matter if the K one OCs +100MHz when the non-K is so much cheaper?

Scenario2:
Or maybe we can see cases where the non-K actually OCs better, like it can happen with Zen CPUs (the non-X OC-ing better than the X CPU).

I would not be so sure if I were you.

I think this is an unusual situation, one that will be "corrected" soon by intel with BIOS updates. The same as they will take the 512 AVX away from AL, they will take this "happy accident" away too, unless they like to shoot themselves in the foot.

Something similar happened with Z170 & Skylake, so I went with i5 6400. Sure enough it was killed pretty fast via microcode updates and what not. So I was left with high end MBO and low end CPU. Worst thing is that getting used CPU for upgrade never because cheap enough, so I was stuck with that combo, literally new MBO+CPU would be better buy than a 2nd hand better CPU for Z170. Not going to do that again. Guys like debauer can afford playing with stuff, while I usually keep my system for years, so any bad bets will get me years of lower performance.

maybe they should let the K sku to have e Core while non K has no e Core

ATM the non K i7 still have e Core


idk how intel will segment their product, adding eCore make paying more for K Sku justified since at least on i5, when u buy K sku, u not only get better bin, but also larger die chip

BCLK overclocking is no problem at all on very CPU but how is with side effects?
BCLK is 100MHz and all timings are calculated for 100MHz value, eg timers.

BCLK overclocking died when Intel tied PCIe and SATA clocks to the same clock generator which limited tweakability to 5-7%. Looks like they have been decoupled on Alder Lake so this no longer is an issue.
