Anyone using a 12900K for MSFS ?

[GSalden 4,656]

Hi all,

Today I upgraded my front view server to a 12900 K /  Asus ROG Strix Gaming D4 / 32 Gb 4266 mhz cas 16  ( already had a R`TX 3090 ).

Anyone using a 12700 K / 12900 K and might share his config for the cpu ? It has fast P-cores and slower E-cores. How to set them up so it is best for MSF`S ?

Thanks in advance.

interested to hear what people say as I'm considering this cpu upgrade also.  PS: just curious.  How is your p3d performance with these?  I'm interested in p3d and msfs

Just finished the hardware update + W11 Pro + all Windows updates.

In the coming days I will start with several apps and also MSFS. Regarding P3D, that will be installed on my current cockpit suite pc (Prosim) which will be upgraded with the 7940X / Aorus X299 mobo / 32 G GSkill Trident Z 3200 mhz cas 14.

That pc will be the server pc (P3D) and both client view pc’s will have MSFS  installed. That mix will be perfect for my home cockpit.

Sorry, I'm on the road for a while and can't help, but look at this, please.

On P3D and MSFS is very fluid and stutter-free, I overclock only at 5.0 with very low temps and AVX 0. I did something else but I will let you know.

Awesome that should be fabulous Gerard I'm jealous!

Is that ram Samsung B-Die?   I'm running a 12900k / Asus Strix D4 / 32gb G. Skill 4000 C15 / Strix 3090.

My G. Skill sticks are 4x8gb B-Die.      I don't know whether it's the board or the 12900k,   but my sticks don't like to run 1T command rate.   They don't like to go faster than 3600mhz in gear 1.     I suspect it's the board.

They ran 4000mhz fine with my 10900k / Asus Hero XII.

One of Buildzoid's viewers bought him an Asus TUF Z690 D4.    He threw some good B-Die sticks in there,  so I just copied most of his tertiary timings.  I didn't go as tight with tRFC though.

Right now I'm running gear 1@ 3600 / 2T /  14-16-16-36-52.     I'm using the 100:133 dram frequency ratio.

I want to sit down and see if I can get gear 1 stable at 3800 to 4000mhz.   I'm not optimistic.

I need to sit down and see what I can do with max dram MHZ in gear 2.   Jumping from 3600 to 4000 should offset the latency penalty,  but give higher bandwidth.

This board was a challenge initially,  so I just took the easy road for starts.    I think the bios still needs some work.    Fun though.

Haven't had time to sit down and see what  I can squeeze out of the cores yet.   So far I'm really enjoying this platform.     I want to emphasize P-Core performance,  while still clocking down at idle.     My 10900k had an all core 24/7 5ghz clock.   It pulled in the neighborhood of 300 watts while overclocked.   Trying to move away from that.   Especially since the 3090 can pull between 350 to 500 watts depending on configuration.

I did a quick and dirty OC with "OC by core usage".    

I took some tips from Skatterbench,  and from Der Bauer.   Skatter used an Asus board,  so the direct correlation is easier at first glance.    I copied some of his settings for "by core" and "TVB",  and "adaptive Vcore".

I can tell you this,  this 12900k is a BEAST.   It kills my 10900k @ 5ghz in every possible way.  It's pulling 50 ish less amps while doing it.  Really enjoying the potential.   I don' think my sample is a particularly good one.

There are different schools of thought to pursue.

High dram frequency vs low latency

All core oc

By core usage overclock   (Way to go is my initial instinct)

And,  then there is the disable all E-Cores and clock the stuffing out of the P-Cores.     This strategy allows you to run MUCH high ring bus ratio.   The E-Cores drag the ring bus stability down,  and just add a heat load.   Talking gaming type work loads.

The 12900k at default frequencies walked all over my 5ghz all core 10900k.  I did this as a quick and dirty p-core "by core usage",  and it stomps a mud hole.     Didn't play with ring bus much yet,  should be a lot of performance left  on the table.

edit: forgot to say,  I'm on a NZXT Z73 360mm AIO.    I have the new socket 1700 EK water block on the way.  I WISH I could find some ddr5 sticks somewhere,  because this is looking real sexy for the price ->https://www.ekwb.com/shop/ek-quantum-msi-mpg-z690-carbon-ek-x-d-rgb

looking at these screens,  I think I need to try system agent voltage around 1.2v.

Want to try to set min / max ring bus to 39.    The E-Cores really drag the ring bus frequency down.   I've seen it hit 37x while benching Cinebench,  default setting.   

39 should decrease latency all around,  and give a smidge higher bandwidth.   So many possibilities with this platform.

Forgot one thing,   I found the latest bios here: https://www.overclock.net/threads/official-asus-strix-maximus-z690-owners-thread.1794802/    Shamino works for Asus.

edit:

looks like Asus just dropped a new bios yesterday,  https://rog.asus.com/motherboards/rog-strix/rog-strix-z690-a-gaming-wifi-d4-model/helpdesk_bios

Curious as well.  Bought the 12900K when it launched, was able to snag a motherboard, but have been held up trying to buy DDR5.  Finally able to get it, but had to get it through Newegg and their Combo deals.  Now I'm stuck with a second motherboard.  Linus, Jayz2cents and Debauer have great videos showing how they've been able to play around with the P cores and the E cores.

Just upgraded to 12900k, 32gb DDR5, gigabyte 690 board, zotac 3090 on Win11. Built by Overclockers but not overclocked as i understand,

I have zero overclocking experience. How much am i missing out on here? The curiosity/tinkering aspect has no appeal to me and i don’t fancy upgrading my water cooler to anything beefier. Also not sure if it would need a bigger PSU than my 850w.

I have been running a 12900K and 3080TI DDR4 4400 Ram for a few weeks.. No OC.  I am a VR user (HP2) and the biggest improvement for me is been able to run OpenXR @ 100% and Insim render at 100%   You need plenty of cooling to run the 12900K at 5.2 .. I am also using a 1000W PS

I upgraded a few weeks ago... 12900k, Asus Prime Z690-A, 32GB DDR5, and the RTX3090 FE I pulled from my old system. Windows 11 to take advantage of the e-cores. Running 3440x1440, DX11, mostly maxed sliders, I get ~50-60 FPS with the Bonanza Turbo in the Chicago area with most of the payware addons installed (Drzewiecki's Chicago Landmarks, FSDT's KORD, FlightFX's KPWK)

I'm not overclocking and honestly don't think it's worth it on these new chips. Running XMP1 profile and mostly auto settings. The SVID settings can be worth looking at... I got better temps with the Training profile, but also got BSOD's with this profile when the system was cold (there has been a BIOS update since that improved stability, so I'll need to give it a shot again). I'm on air (NH-D15S) in a cramped case and ended up limiting the PL1 wattage to 200W to keep the CPU from throttling (the default 241W quickly hits 100C during burn-in with Prime95). Even so, this chip runs HOT in the 90's on tests like Prime95 or Blender Benchmark, but normal usage is much cooler. I haven't messed with the efficiency cores... would rather leave them enabled for better power efficiency during regular browsing than disable them for a tiny boost in p-core performance. I should also mention I'm undervolting the 3090 and running it at a 90% power limit. All that power limiting leaves me in the lower 20th-percentile for 3DMark benchmarks, but the system is still wicked fast.

I came from an ancient 4th gen i7-5960X that I spent a lot of time overclocking and tweaking... it conveniently died a week before Alder Lake was released (nothing related to the OC). It was almost 7yrs old but that system was still a beast, and with the 3090 I never dipped below 30fps. Being an Intel word not allowed due to bad experiences with AMD a long long time ago, I'm glad they've finally released something competitive and interesting again! Definitely worth the upgrade if you've been holding onto an old system, or if you are the fence because your current system is still decent, wait for Raptor Lake next year which will likely be more efficient and won't face any of the early-adopter headaches (like the horrible timings on these DDR5 chips!)

Beats my 11900K by a country mile, makes me regret that chip purchase.

The timings on DDR5 are a lot different than what we’re used to with prior RAM modules.  They are pretty much equivalent to the best DDR4 Modules you can buy today.

But as with DDR4 and other DDR generations before it, the timings will likely improve significantly after a year or two when the modules become more popular and the manufacturing processes improve. Not to mention cheaper!
