Alder Lake i9-12900k

Yeah they are not compatible with 4…

That’s what I thought, obviously don’t fit the slot but assuming the chipset can regognise it then quite possibly there’s an adapter already available.

I’ve created a separate thread for a standardized test flight as a basis for better performance comparison between different setups & settings:

Looking forward to seeing you there!

I bought some geil 4800mhz ddr5 but one stick was doa so I wouldn’t recommend

Would anyone mind sharing what cooler you are using with Alder lake.
confusing information online about 1200 being compatible or not.

If you are looking for a water cooler, I bought this, working perfectly with overclock REBELLIOUS AND DISTINCT - MAG CORELIQUID C240

I’m opting for the Noctua NH D15. I’ll be doing BIOS AI overclocking only and there is strong evidence from people smarter than me that this is plenty not to mention a lot less trouble than AIO.

The NH-D15 is an absolutely amazing cooler and if properly installed (which is quite easy) will give you temps that are even better than with some AiOs. I dare say it’s still the best air cooler on the market, and that also factors in build quality etc. There’s just a couple of things you need to make sure:

  1. Does it fit your case? The cooler is insanely large and especially high in terms of height perpendicular to the mainboard (the fans are d=15cm, and then some). I had one case where I could not close the side door when the Noctua was installed.
  2. Do you have enough clearance to your MEM sticks? Especially memory sticks with large (high) heat spreaders can get in the cooler’s way. This will only happen with very few sticks, but keep that in mind.
  3. Get the proper version of the cooler. I seem to recall there was one with slower fans giving you some degC higher temps, but that had an “S” in the name IIRC.

The only reason I switched to water cooling was because I wanted lowest possible temps so I built a custom solution. But especially in terms of idle noise (pumps!) I admit I have been looking back to the Noctua. If your CPU is idle or performing low load tasks, the Noctua’s fans won’t even need to spin.

Enjoy it!

I’m using a custom solution based on the Alphacool Eisbaer Extreme that I bought for my 11900K (Socket 1200). The CPU block is the Eisblock XPX (not the “Aurora” version) and it is compatible out of the box with my 12900K (Socket 1700).

Just to add: The fans on the NH-D15 can be fixed at different heights of the cooler (perpendicular to mainboard) within a range of IIRC 1…2cm. This way the MEM stick issue could be mitigated by mounting one of the fans a little higher, but that would in turn mean that there is enough headroom between top of the cooler (=shifted fan) and side door of your case.

My dh15 is not able to handle the 12900k power :grinning_face_with_smiling_eyes:

100 C peaks with 1.3 V and xmp settings rest default msi bios… 241 w max…but it only peaks short time…

Arctic Liquid Freezer II 360 all-in-one watercooling. It needs a socket-1700 backplate that I had to order (free) on their site, it arrived in a week.

Does anyone tried disabling E-cores? I have 12700K and with MSFS running one of them is always almost maxed out and MSFS is limited by main thread. I have tried flying over Helsinki (new PG city), and with E-cores enabled and stutters were really bad. After rebooting and disabling E-cores in BIOS flying the same area was much more smoother.
I’m using windows 10, Quest 2 (max resolution) and 3080. I wonder would win 11 fix this, but I don’t want to upgrade now.

Just lower LOD from 9.0 or whatever it’s running at.

And check in taskmanager that virtualisation is disabled.

That was actually one of the first things I did after I installed the 12900k. I don’t need that many cores and prefer to max out the CPU on the P-cores instead. Aside from glitches due to inefficient scheduling.

In theory, Windows 11 includes an OS CPU scheduler that is intended to work better with the internal hardware scheduler in Intel Alder Lake, called HFS+.

How that plays out with MSFS I do not know, I have not tried it myself, I still have to build my 12th gen computer. It may or may not require an update from MS/Asobo. Maybe others users can chime in.

If that helps, my upgrade from W10 to W11 was completely painless FWIW. Of course YMMV but I would recommend doing the update for the sake of benefiting from the Alder Lake scheduler.

How do you disable E-cores? and why is that a good idea?
Just upgraded to 12700K from 6700k and still see limited by main thread :frowning:

Let’s hope so.

There should be a bios setting for that.
I am not advocating disabling e_cores, just pointing out the way it is done :slight_smile:
