*** The Official Alder Lake owners thread ***

It was suggested to me by Arctic to either remove the entire AIO from the PC (ideal) or at least turn the PC case upside down so that the rad faces the bottom (rad in the top of the case) and the pipes and the block will then be extended upright. That way less chance for a kink or any internal pressure to force more liquid out of the AIO when the old plate is removed.
 
Hello folks

Had a 12700K for a few months and after recently updating my Asus Tuf Z690 Gaming Plus Wifi D4 from bios 1304 to 1504 I've noticed that it no longer boosts a couple of cores to 5Ghz. (The P Cores get to 4.9, but before there would always be a couple of cores that would boost to 5)
Looking at HWiNFO I notice there are some 'Performance Limit Reasons'...
IA: Electrical Design Point/Other (ICCmax, PL4, SVID, DDR RAPL)
IA: Max Turbo Limit
RING: Max VR Voltage, ICCmax, PL4
What does this all mean? What can I do about it?

ThrottleStop showed similar results.
I chatted with the writer of ThrottleStop (unclewebb) over on the LTT forum and he wondered if this might just be due to the eccentricity of Alder Lake.
But I want to get to the bottom of this!

Just to reiterate, everything is pretty much at stock - I have turned on XMP 1, turned off MCE, but that's really about it.
What could be going on here?
This has only happened since I updated my bios. I may well end up rolling back.

Of course I could learn how to overclock and get it to how I want it. But first I want to get 'stock' as good as it can be. It bugs me that I haven't tinkered with any settings, but just updating the bios has slightly hobbled my CPU.

Any help would be very welcome!

It would be particularly good to hear from other 12700K users on Asus boards - what bios etc.

Thanks
 
Turn on MCE. Disabling MCE starts making the chip respect hard power limits thus limited boost and performance and flags in HWINFO. When you update bios, all settings reset and new bios might toggle certain settings.

Unless something is wrong, there's not a reason to update the bios.
 
My MCE is off, get cores boosting to 5.0, no flags.

MCE will result in the CPU hitting much higher temps much quicker too. Expect thermal throttling in demanding tasks.

With ADL the preferred cores boosting can change from what I've read. It could well be that Asus optimised the way the boosting works and as such on your partiocular chip the preferred boosted cores aren't meant to boost as high as they did on the previous bios. Each chip will be different though.
 
The best thing is to lift all power limits and use adaptive + CEP + AVX guardband to tune adl. But I figured that's probably a bit too advanced given the nature of the post. Thus the easiest thing is to enable MCE on Asus, enable XMP and go from there.

Thanks. Yeah, I'm pretty ignorant about such things so your instinct was correct. It's just weird that with the previous bios, I never had MCE enabled but I would still have a couple of cores hitting 5Ghz.

Thanks for the info mrk.
But your HWiNFO screenshot doesn't show the 'Performance Reasons Limitations' section - that is where I'm noticing the flags.
 
With stock behavior, intel use TVB = Thermal Velocity Boost which lets the cores scale up/down based on temps. What might have happened is that bios FW coincided with warmer ambient temps thus limiting the boost range and/or TVB3 got disabled in new bios. The difference between 4.9 and 5.0, while optically satisfying, isn't doing anything notable for performance.

With MCE you'll naturally trip up power limit flags as you're telling the chip to respect the power limits. This will show up in hwinfo as various flag types depending on which gets hit first etc

Ah yes I hid it ages ago because it never shows any limitations on my setup so saw no reason to have it showing, enabled it just now and it's still empty :p

Now I know nothing about overclocking and stuff so I'm striving to see things while blind...
But I notice that your PL1 and 2 Power Limits are set to 4095W, mine is set to 190W (which I thought was the safe limit of 12700K).
Maybe I should try raising this figure a little?
Because the 'Performance Limitation Reasons@ flagged by HWiNFO do say that it might be to do with PL limits.
 
Yeah PL1 and PL2 are set to 4095 by default on Gigabyte - Stops any power limit issues and really PL is only really worth keeping an eye on in a laptop or SFF where cooling isn't as free. No reason why you can't set your PL to the same as well unless there's some reason anyone else can think of. I have not changed any values for PL, just set the RAM voltages and timings manually as I don't use auto XMP.
 
Upgraded my BIOS on my Asus Z690 Formula the other day to the latest (1702 I think) and all of the offsets on the my adaptive overclock stopped working. Also my manually set ring cache ratio stopped being applied too. Downgraded back to the previous BIOs (1601) and everything was fine again.
 
The only thing that seems to allow me to backup and reinstall after a Gigabyte BIOS update is the fan profile.
Everything else is to reapply manually.

@mrk Yeah, kinda remember that time.
Some things are worth passing on. Have you got your Arctic repair kit yet,..? Mine has arrived and will be done, when I get my head around stripping it down
 
Not got my kit yet, but the gasket only starts to erode after a couple of years so I am in no major rush and will almost certainly wait until I've upgraded to 13700K or 14700K (most likely) and gone the DDR5 route with the next upgrade.
 
my gasket repair kit came today, still waiting for the lga 1700 frame kit. might wait till the raptor lake cpus come out to decide if its worth upgrading to or not before messing about with the watercooler.
 
And that's why I guess intel is killing it with alderlake
