ROG MAXIMUS X HERO bios 2402

*Updated Microcode for security issue.
*Improved system performance and stability.
*Improved DRAM compatibility.
*Update ME FW for security issue.

Anyone tried this yet? I'm particular interested in memory o.c. can't get my 8700k above 4000mhz on my 4400 rated ramkits.

I have a Max X Hero (wifi) and the support page still lists BIOS 2301 so I guess they have not posted the new BIOS yet. Looks like the main changes are a ucode and MEI firmware update for another Intel "security issue". The other 2 descriptions - Improved system performance and stability, and Improved DRAM compatibility seems to always be listed. I remain hopeful!

If you have problems with ram frequency, go to skew control under dram timings menu and set rtt_park for both channels to 120 for single rank ram and 240 for dual rank ram. You will be able to use the maximum freq after that.

i had the same issue with my 8700k and 16 gb of trident z rgb 3000 mhz cl-14-14-14-34 kit 4000 mhz 18-19-19-39 was my max anything past that and code 55.

does this work with z-390 ? i have asus xi code z-390 with 8gb x 4 sticks of team group 4133 18-18-18-38 1.40v @ 4266 17-18-18-38 @1.50v
would this settings help me get past 4266 ?

It should work just fine. For me fixed the freq problem. With rtt_park on auto my ram couldn't clock more than 3800. Now im on 4400 on a z390-e gaming that officialy only supports 4266mhz .

Thank you so much, ive now broken through 4000 for the first time ever! and hit 4200. But I can't get past there. Any tips for getting to 4400? running 4200@1.45v tried increasing to 1.5v for 4400 but no luck.. anything else i can do in skew control etc.

ramkits are Patriot Viper Steel DDR4-4400 rated 1.45v

After this tweak are you guys running HCI MEM test for etleast 1000 % coverage or using TM5 memory test app so you dont assume its stable and corrupt your os ?

Since this BIOS I have a 5-6 second POST screen which annoys me. I cannot find the option to change the delay like I used to with older BIOS versions. Has it been moved or removed?
