Correct me if I'm wrong, but the Alder Lake non-K overclocking features is mostly due to PCIE being able to be decoupled from BCLK overclocking. BCLK overclocking has always been there. Just that since Sandy Bridge until recently, it can only be pushed around 2.9-6% (depending on the CPU architecture), whereas der8auer seems to get 15% here.

From skylake it is already decoupled iinm. Last time there's pcie/bclk ratio so even when it is synced, it wont be an issue.

The problem comes when intel put a bclk governor on the nonK cpus from skylake (remember asrock skyOC fiasco), causing it to calculate the bclk and intentionally refuse to boot. This hideous thing seems to be gone on alderlake non-K

K series iinm can crank the bclk but is pointless since you can crank the multiplier anyways.... so the bclk in this situation is mainly for pushing a little bit more where the multiplier values cant.... for example 100x55= 5.5ghz to 101x55=5.55ghz because 56 multiplier will not boot no matter what

my old i5-6500 bclk oc

Was this the Asrock BIOS that Intel forced them to take down?

it was never taken down. but newer bios were patched to fix this. back then, intel was too arrogant.

That one came bundled with gulftown. Pretty compact cooler with blue led fan.

Guess intel forgot to put on the bclk governor component? but isnt K series overclocking also not covered by warranty recently?

Speaking of which, i have not encountered a board yet that cannot change bclk... problem is whether can boot or not jer.

I guess intel is secretly glad also... afterall rarely an average user will buy K series anyways and now this will make many choose intel over AMD.

this is not about changing bclk only buddy.

you need an external clock generator which requires extra components on the motherboard. and afaik there are only *a few* ddr5 boards that have these.
so actually this is not a really big thing. if you are set for ddr5 ... ok you can save a few RM but if DDR4 is an alternative you can get a K CPU with the same capacity RAM for much less.

Isnt debaur latest video sort of went around his assumption of needing an external clock gen with a midrange B660 board with a later video? Because iinm since skylake bclk is decoupled already.

He probably assumed external clockgen is needed because he didnt see the bclk enable/disable inside tweaker's paradise on the cheaper board but later found out it can be done straight away on his B660.

Not sure now but asrock has been promoting the bclk overclock settings in their manuals on most of their boards including their super cheapo ddr4 boards



Also from assrock b660m itx. Siap ada slider to slide lol.


Msi, gayaybird and assus's manual got no details on the bios so i dunno. That's why im also semi doubtful cuz cant find much info or user tests but all assrock seems to have it.

I'm not watching his videos but to put it briefly, no. Without a external clock generator you have a significantly lower range. Without having tested it you're probably gonna max out at 130 if not 120 or earlier.

Perhaps assrock will be putting external clock gen on their boards since they have indicated it on their bios about having bclk oc on it. Or perhaps as you said, capped just like dbaur crank to only 115 on the B660 (didnt test and mention about going higher) but even 115x45 for example is already pretty high for an all core speed.

But well, just need more people to test it out then.

clarification after checking; 103 is the limit enforced by Intel, above that you can only bypass with the external clock gen. (techpowerup's latest review)

asrock also has a hand full of boards with it but I doubt they will add it to others (especially budget ddr4) as that would mean another revision had to be launched.
and that is disregarding whether or not there is space on the current layout for the chips to be placed, which especially for itx,... will be a major issue.

That's why im very curious due to debaur tested b660 board can do it too. That's why i mentioned did intel forgot to put that limiter on alderlake. That 103bclk mentioned by techpowerup is a govenor that are all on the previous gen nonK cpu. (Supposedly external clock gen should not work either)
https://skatterbencher.com/2021/11/04/alder.../#BCLK_Governor

And even so, it also means we can whack a 12600K and put it into a B660 and overclock it with bclk.

I know. But it was already established that at least for ASUS that on B660 it just works on the G GAMING and F Gaming. Since it doesn't work on the others that would contradict a missing/deactivated governor.
Unless you use a K CPU, which doesn't require an bypass anyways, yeah.

Deswai confusing and alot of contradictions now haha whether that governor is still active or not because according to spec it should not be possible even with high end boards. It's confirmed on those 2 B660 boards because those are the only 2 b660 board he has. Techpower up also macam did not mention whether their z690A ddr4 can work or not as well.

Unfortunately, really have to wait for the GN and HWU jokers to test because they got more board endorsements. *Inb4 they dunno how to manually tune memory without xmp and cannot boot so conclude it doesnt work.

oh no, I can take your hopes right there. hardwareluxx.de already tested a few boards which couldn't do it.

gaming g is a decent mAtx board with ddr5 support and it doesn't cost a bomb either. And u do get this ahemm.....unofficial oc thingy

Haha im going for 12600k/12700K and z690i anyways. This is more on curiosity because got contradictions in the reports

maybe similar latency to DDR4-3200 CL16
