PPD also helps a lot what you are talking about. Even in MemTweakIt you can change and see the difference.

 

Why command rate 1t no work?

@Takukou @sabishiihito Here is the 1t optimized bios for the Z490I Unify that I modified to remove ucode. Can y'all test if it works and scores properly?

z490i_12z_no_ucode.7z

how can work a bios without ucode?

I'm interesting to make for my unify

@pipes I'm not sure honestly, but it seems to work on Asus boards.

@pipes Non ne sono sicuro onestamente, ma sembra funzionare sulle schede Asus.

I want try this when I will resolve my temp on custom loop problems too high always 100° C with linpack stress test

I have try and flashbios work fine, now want try the differences

can get over 5 ghz, always same 5 ghz frequency

I don't think 5 gig is an artificial issue. My chip can bench 5.2 ( multithread like CB ) and I've run xtu @ 5.1 on sub par cooling.

If anything I gained 100mhz benchable over my buggy/broken from day 1 ASUS z490 Itx -013 serial # board.

I'm sure if I swapped the cooler in the prototype i'm working on to my liquid freezer 2 280mm I could get over 5 gig stable.

Has someone measured the performance improvement without ucode yet?

@hansglans I have. See EVGA Z490 post.

Is that 1% improvement for 10th gen really worth it ?

Is there any chance for a no u-code version for the atx or any tutorial on how to do this?

@yaqy123 I can make a bios for the atx, but if you'd like to do it yourself:

Download and unzip all the things I provided. Open the bios image in MMTool. Go to CPU Patches and delete all of them. Save image. You can now flash that bios and it should work just fine.

Once you're in OS, go to thing I have as "tool" and look for a task called "patch for no-ucode." Then go to task scheduler and schedule that patch to run on every login.

For best results, you want to also be using InSpectre to disable in-os mitigations.

Please report results.

Thanks for the info, ill just make my own when a good bios is finally released for the atx. 

@yaqy123What are your current OC limits on that board? 4300c16 1t or something like that?

Wont even post 1t above 2800Mhz. For ram im just running 4400 16-17-17, 4533 is a bit wonky with weird reboot instability. Just waiting for a better bios atm.

@yaqy123 Do you have all your subtimings manually tuned?

C'è qualche possibilità per una versione no u-code per atx o qualsiasi tutorial su come farlo?

I have try this bios without microcode, no problem but it's impossible to overclock the ram

Is there a way to apply the saved 12Z profiles to your modded 12Z? Reapplied all my settings and profiles recently way too often

What does the "patch for no-ucode" do? I have task scheduler disabled, is the tool really necessary?

My RAM setting no work with CMD rate 1t and setting manuale...now i understand why it was sold on amazon wharehouse ... ass fucked that i got ... an almost ridiculous system this z490 ... potential oc equal to 0 ... and they also want the money for these ill-conceived platforms
