I feel a bit noob now, but what is ODT? :)
On-die terminator. The sittings are under "Skew Control". For DR bdie the values are around: RTT_WR=80 RTT_PARK=40 RTT_NOM=40.

You can try RTT_NOM from 34 to 48, depends on your rig.

Ok thanks, I will do that when I get my sticks back. So a lower RTT_NOM number is faster, and a higher number is easier to boot?

Those are ohms. You need to match the build quality of your sticks. Higher ODT will cancel the signal reflection, but weaken the signal strength on the sticks, you need to find the most proper ODT for your sticks.

So...you gotta be an electrical engineer to figure out DR memory it seems. No chance in hell I would have thought about this on my own. I thought the Asus BIOS team would program the BIOS to do this well on auto settings, but clearly not.

ASUS team is now slow on improving the bios...MSI releases BIOSes every one or two weeks

Just need to try 80-40-40, which worked for most people ;)

What memory? I saw you had recently bought 2x16gb and I do not think the Hero will do any better than your Ace. It does best with 4x8gb. Best I can run and be stable on the z390 Hero is 4266/16/16/16 with 4x8gb. I would think 2x16 you would be lucky to hit 4000-4133.

I tried some Team 8pack Edition 2x16gb 3600c16 in the z390 Hero and I think it topped out around 3800(didn't play with it much as I was in the middle of trying to figure out why z490 Hero sucked so bad for mem OC on 4x8 or 2x16).

The z490 Hero is not much better for 2x16(4133) or 4x8(4000 so it is worse) than z390. Asus lost it on the z490 model. I just got an z490 Unify and it will run 2x16(4600c18) and 4x8(4400c17) ranges and it trains and boots fast. The Unify will do about what the z490 Apex I have does for memory OCing.
Yeah, they are 2x16 DR G.Skill 3600C16's. I run 3850 14-15-15 on the Ace. Any divider over 3800 is a no-go so I just added some BCLK to it to get to 3850 which is stable.

Meh, I might still get it just for the already delidded KS and just test the board out. If it does worse or the same I'll just put the KS in the Ace and sell the Hero again with the 9900K and my old 2x8GB kit in it.

So Much missinformation here.
Idk where you get that the z490 hero can only run 2x16GB up to 4133?!
Im running 2x16gb trident Z rgb 3200 c14 dual rank @4500 c17 on maximus XII hero z490.
Single rank i can Do 4600+.
For quad dimms 4200 is the Limit.

I tried to get a Z390 Apex but they are totally unavailable on the secondhand market and the new price isn't justifiable for me so when I saw this Hero with a delidded KS come up I just made an offer lol. More for the KS then the board but IF the board does better with DR sticks it would be nice hehe.

I mean, the Ace did 4400 just fine with 2x8 but won't behave with 2x16 above 3800 but I'm not sure if that's the board or the IMC of the CPU's fault really. We shall see if the deal goes through what happens.

Please post some Aida 64 benchmarks and memorytests on 4500c17 2x16GB :) Looks like you found the OC key :D

Running i5-10400f at 4GHz all core and cache on an Asus Z490-P, sticks are Patriot Viper 4400 cl19.
AIDA random access latency is 53.1ns average over 5 tests, regular is 45.76ns.
This setup seems to be relatively stable at 1.3v SA and IO(for at least 40 minutes in TM5) with 1.4v DRAM, previously I was on IOL 14 with 1.2v IO and stable for at least a night of TM5, apparently going up 0.1v only gets me that one offset.
Timings should be basically jedec, wondering why I seem to be unable to get higher freq/tighter CL and can't even get above 3200 CL16 if I try CR1.
I've seen someone else get CR1 CL14 with what should be the same setup.
Any ideas/suggestions?

Me and Tyllo on the OC discord found 80/48/40 worked well for our gskill dual rank 2x16GB sticks (on his M12 Apex and my M12 Extreme).
He and Yaqy also had massive gains in yeeting some timings by setting DLLBwen=0, and 0 made some impossible to boot timings able to boot.

I also fixed my RTL's.

Where is the DLLBwen setting in the BIOS and what does it do? Nice resultes btw :)
5.0/4.7 is your new 24/7 CPU setting? Have you tried 5.2 with HT off just for gaming?

Thank you!

Can you help me download from this site? It's impossible for me :p
No problem. Just 2 steps you should be able to download it. No account needed. I cant attach a zip or rar file here.

Yup, DLLBwen is found also depends on the frequency, 1 worked for 4500- and 0 worked for 4600 and 4700. RTT_NOM can be fine-tuned between 34 and 48, depends on the ram. I am running 80-40-48 for CHA and 80-40-34 for CHB.

** Off Topic **

Has anyone here purchased an Apex XII recently? If so, are they shipping with the B3 stepping of the Intel I225-v lan controller yet?

I need to login with QR code or something...

Looks like some of the bioses is here too:

But it not like twice a week bioses with Msi z490 :p
