CENS Posted December 26, 2022 Posted December 26, 2022 (edited) 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.

spit051261 Posted December 26, 2022 Posted December 26, 2022 (edited) Very nice ? At last Clem , well done bro. Edited October 17, 2023 by spit051261 1 Quote
zippytek Posted December 26, 2022 Posted December 26, 2022 Looks good, will give this a shot today. Was seeing much different behavior tuning mem v z690 dark and the voltage guidelines here explain it. Thanks! 1 Quote
zippytek Posted December 27, 2022 Posted December 27, 2022 anyone have anything working for command rate 1T on z790 yet? seems it will post in at 8200 C34 1T but I need to go down to 7400 to even attempt to boot windows...and then instant bsod (mem mgmt). will test more but curious if anyone has had success z690 dark was very strong for 1T...

CENS Posted February 3, 2023 Author Posted February 3, 2023 (edited) 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. Edited February 3, 2023 by CENS 2 1 Quote
CENS Posted February 4, 2023 Author Posted February 4, 2023 (edited) 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: Edited February 4, 2023 by CENS 2 2 Quote
Broken APEX49 Posted February 5, 2023 Posted February 5, 2023 As a representative of Japan, I would like to ask you to lend me your services.(ﾟ∀ﾟ)ｱﾋｬ 1 Quote
keeph8n Posted February 6, 2023 Posted February 6, 2023 @CENS I don’t know if you, Luumi, or Biso Biso can give any insight. Z790 Dark KP 13900KS 7600 gskill kit tried four different Zotac 4090s and this board just fails to post. Boot loops memory initialization codes. 53, 54, and 7F. I’ve swapped memory kits, nvme drives, sata drives, coolers, etc. nothing. Won’t boot. zotac gt710 boots just fine Quote
CENS Posted February 6, 2023 Author Posted February 6, 2023 (edited) Well I tested just a few "next gen gpus" and one MSI. No issues. I assume you updated to the latest bios? edit: I will give the bios team a heads-up. Edited February 6, 2023 by CENS Quote

I’ve been through every public bios. just infinitely boot loops with memory initialization codes and flashing red LEDs. Tried both slots. Quote
Braegnok Posted February 8, 2023 Posted February 8, 2023 CENS, thanks for all your hard work. I'm running the 8000 CL32 1.68v profile as my daily on Z790 Dark with i9-13900K ? Looking forward to the upcoming 8533 CL36 1.52v profile. I had a bad experience with Intel Z690 Apex trying to OC memory, was going to skip Intel Z790. Bought the Z790 Dark a few months ago, and the experience has been wonderful. 1 Quote
CENS Posted March 1, 2023 Author Posted March 1, 2023 I can highly recommend new bios 1.11 it has the latest patches and 8533 daily stable profile. You need decent dram and imc ofc. 2 Quote
ironage Posted July 2, 2023 Posted July 2, 2023 @CENS you know if this Board and/or Z690 Dark is gonna get RPL refresh support ? Looks very much like EVGA ist done with motherboards: Quote
spit051261 Posted December 23, 2023 Posted December 23, 2023 (edited) Here is a good one. Trying to return my KPE board for RMA and every time I try to login , password no good and this is after telling them my board is bad and needs returning . I have tried all day to login. I get "you have logged in too may times" and password no recognized (after using the recovery password they sent). Times can't be that bad for EVGA , surely ? I actually started the process yesterday and they replied . As soon as I mentioned RMA , end of sports . Edited December 23, 2023 by spit051261 2 Quote
