The manual is the box and when I looked at the driver page i don't see any missing. Also drivers should come on a USB stick or CD with the MB in the box.

Sometimes even loading defaults will not clear/restore some settings so I would try to clear the cmos by removing battery as a last resort if nothing else works. If the battery is difficult to get at...

I have had issues with a z490 Apex and using bios flashback. The first was the manual had the flashback port incorrectly labeled. I had to look at the rear io to find the correct one. Assuming that...

I would set Disabled MRC fast boot and Enable the memory training.

This a really in depth question/answer with all the settings involved. If you are really interested in getting the most out of...

That portable version of MemTweakit posted does work correctly with z490, it shows many timings incorrectly.

It is useful for seeing RTL/IOLs in Windows as those are correct though.

Was the battery dead or does replacing it with a new one still cause the issue? Good job figuring it out, that would have been a tough one.

I found when I select US/English it breaks many of the Asus sites. When I select Global they all work.

I have a z390 Hero and prefer the older bios vs the newer. 0602 is best for 4 dim mem OC for me and 1602 is next. I didn't mess with 1704 much but the little I did I found the older better for mem...

Probably not much difference in performance either way unless you are doing something that needs more than 32gb of ram.

As for what to do with each bios that is hard to say unless someone has the...

It runs with Z490 Apex but some of the numbers are reported incorrectly and some are blank. I have tried bios 0088 and 1002.

It nice that it is portable though, thanks.

I do not have any of my Asus systems running right now but I used MemTweakIt 2.02.48 and MemTweakIt 2.02.46.

The only thing similar to Memtweak it that still work with the lastest Windows updates...

I would try is putting another PSU in and seeing if you have the same issues.

That is an AMD setting, maybe you are thinking of PPD on Intel? If so that is only on some of the new Z490 boards.

If you want to find a setting in your BIOS look at the top, its says F9 use that...

I can tell you that just because the bios say LED enabled does not mean they will work. For example if I set the LEDs in software to off and unstill the software the LEDS will not work even though...

So you have them working now? If so what did you do to get them working?

What software do you have installed to control the motherboards RGB?

When I had it were there was no RGB I installed Aura and it worked again.

Probably not unless you just want to experiment or play. It might allow a slightly better memory overclock but I haven't noticed anything else over previous bios.

No I normally do not use memtweakit. I just use it when testing new memory and mobo settings for quick changes in Windows. Once I have a system setting stable and set via bios I uninstall all apps...

That sounds fairly typical/normal if you are talking a literal 20 seconds from pressing the power button to Windows fully loaded. I have a few different z390 and z490 machines and they vary from...

Just a heads up incase anyone runs into this.

If you are unable to uninstall the update, I am thinking it is linked to doing a disk clean up.

As I had uninstalled the update and turn off auto...

Thanks. I have another z490 Hero coming and will try it with the newer 2x16gb Gskill kit.

What MB do you have?

If the z390 Hero at the bottom of the MB set the Mem OK switch to OFF. Set voltages manually in the bios and they will stay set.
