Minor update to the to the memory OC guideline in the first post. A 8533 stable profile w/ just 1.52v VDD will be added in an upcoming bios:

No need, we synced the patches between the boards. making Z690 as strong as it possibly can be now with the latest updates. No artificial limits due to lack of updates.

https://www.evga.com/articles/01595/EVGA-Z790-motherboards/Default.asp Welcome back for a quick introduction to the Z790 DARK KP. I've always enjoyed TiN's "uncorked" guides on xdevs for EVGA hardware, while this here is far from meeting the same level of detail, I kind of really like it to be in the same spirit. The Z790 DARK KP has additional PCB layers (now 14) and optimized traces to improve DRAM signals. That and the option to have the second PCIE slot to be x16 too for increased space to accommodate external GPU heating solutions are key differenciators and might also help PC builders to route they PCIE extention more efficiently. Once again you can find a selection of OC profiles under the drop down menu within the bios on the top left corner. Explore those profiles and chose one to your liking as a baseline. There is still our PMIC Turbo Mode from previous gen that has been optimized further so you can usually leave it on Auto for the best results. A BCLK patch has been added to stabilize BCLK OC. That really showes effect with ratio-locked CPUs like the popular G7400 where you crank the BCLK way beyond normal ranges. But it might also help in any other case since most important frequencies are generated from BCLK. The rest of the settings are pretty straight forward. The Vdroop / LLC setting is generally best at -25% for most operations and the PWM frequency is usually best at 700-800 KHz. The board absolutely kicks ass when it comes to memory OC. These are some examples on G.Skill 7800 A-Die modules. 8400MHz tight 24/7 on air: 8800 tight in GB3 on air: 9300MHz tight in GB3 on LN2: A general guideline to memory OC on A-Die to MAX out your memory OC with G.Skill A-Die on Z790 DARK on ambient: 1.56-1.64v DRAM VDD (some kits like lower / higher) 1.43-1.5v DRAM VDDQ (varies by kit, need to test with more or less generally keep above CPU VDDQ) SA 1.25v - 1.32v CPU VDDQ 1.37-1.4v (what others call IMC voltage. Requirements vary by CPU, need to test with more or less generally keep ~60mv below DRAM VDDQ) CPU VDD2 Auto (must be set higher than DRAM VDD and Auto follows that rule) This guideline is only partly compatible with green OEM sticks. However the bios also supports certain PMIC controllers on OEM green PCB Hynix A-Die modules that can be unlocked to go beyond 1.435v VDD. These naturally see lower voltage than what you set in bios once you go beyond 1.435v (VDD/VDDQ). For instance you set 1.7v VDD on green modules will get you ~ 1.64v real VDD. Quick note on M-Die: Still viable and works very well on the new board with RPL. My old kit that was really only stable at 7000MHz 24/7 before is now stable at +7600MHz 24/7 and can reach up to 8533MHz on LN2. Software (grab the latest from the EVGA website) Enjoy!

Yes guys can recommend 2.05, they really fixed the memory related stuff with A-Die

Great chip congrats

Awesome

Congrats!

Congrats!

slash the price

Guys, thank you! I'm a bit heavy hearted that these might be one of the last scores with EVGA KP gpus... it sucks. I wonder if there will be any XOC cards this gen.

Congrats bro!

Yes I got them today. Random green pcb: GB3 8000MHz stable, can direct boot 8200MHz with same timings but not enough stability to get into windows. 7800MHz works stable. These A-Dies are insane. Dark is ready! The IMC on this CPU I previously thought was pretty avg tbh.

No idea, binned it myself from like 15 chips. And DARK doesn’t have SP

It is ?

G7400 sold Drop to 795€ on this magnificent 12900KS ?

Congrats on this score! rly nice work

push

congrats! good job

sounds like some awesome changes under the hood improving usability and end-user experience

pretty nice one! good job

I think there is, luumi should have one of his excellent video guides out there.. but I just can't be bothered to use xp

it's not a bug it's a feature no seriously put -1 offset avx and boot one ratio higher than you want to run. Then go one ratio down in eleet in windows then you have flat freq line in anything that uses avx. I'm not 100% sure but I think everyone has it. well non K OC is different. Also memory training is different and changes with cold. But as you can see still impressive freq and tight timings are possible on G7400... however freq can't be as high... better go with low timings on these.

discount and re-added G7400

I can highly recommend latest bios 1.14 - it improves support for 1T vs. 1.10 - it adds microcode selection to re-enable AVX-512 support on CPUs that support it https://www.dropbox.com/s/mbj7q742wigtnb1/1E699114.bin?dl=0 also added to start post.
