Finally got around to getting the asus z390 maximus xi extreme board up and running....wanted to share inital resulsts.....vrm temps are a non issue with this board (2.5 HRS PRIME 95 ) and would guess the same with all the rog boards despite all the negative discussion on the topic....reviews are reviews..thats it !!… having the board hands on and seeing the results is what counts !! ...love the board !!

good news 🙂 now you can play with memory more 😉
when i was tweaking mine, i always went up by 100 MHz
if any problem occures, try higher timings :cool:
i ended up with 4,2 GHz and 18-18-18-36 at 1,35V DIMM and 1,225 IO and SA
but i have 4x 8 GB, not 2x 16 GB so youll have different results probably
here are my current bios settings https://imgur.com/a/8pWMV29 for inspiration


The store did not replace the ddr and then I bought another dual channel kit (not from the same store of course: D) ... 4 x 16 (2 x double channel) I know ... can dare problems, but it seems that with your configuraizone everything works correctly.
I saw your configuration, but if I have stability with your configurations you wrote to me, why change anything else?
what are the benefits?

One thing I do not understand, how did you find Vccio: 0.95 and CPU SA: 1.05? by trial? science? luck?

These are in the Intel 8th gen datasheet pdf. You can find it on google easily. I have a copy on my drive.
Even mentions the default IA AC DC loadline values.

this is probably because i have set in Advanced / CPU (or something like that there) "boot with turbo performace", nothing important
im on 0602

Yeah I saw that setting as well "Boot with Turbo Performance" but still doesnt make a difference.....

you can squeeze a bit more out of your sticks, thats all 🙂 g.skill makes great modules, so why not try :cool:
0,95 and 1,05 are default values, it doesnt need to be changed when RAM frequency isnt too high 🙂

Hi guys

i have too this great motherboard "Asus Maximus XI Extreme" but i want to know if its an hardware problem about the "cpu current capability 140% (max)" when Der8auer or other youtuber can put an max of 170% when some of us are limited to 140% Maximum...

why this ? i fault first because they have an beta or not the last bios but they have the same of us the last 0602...

on the PCB of my Asus Maximus XI Extreme is writen revision 1.02 maybe is depend of the hardware version we have ? an buged version or locked version ?

Or more easy i hope something on the bios we dont activated or disable ?

thank you for your support

I run 5.0 on all cores at 1.181v and am currently running at 5.2 all cores at less than 1.3v.....yes I know I got a super amazing chip and luck. Here's my proof for 5.2

Run Prime 95 version 26.6 non AVX @ 5.2GHZ ....if the chip passes 8k within 20-25 mins ...then yes...you may have a good chip..
Await the results.

Do you know the batch number of your CPU , I would be interested to know.

Considering around 2% of 9900K can achieve 5.2 Ghz there seems to be a lot of 5.2 Ghz Chips out there 😉
