Thanks! I turned off XMP and set memory to 'DDR4-3600' in the frequency menu, voltage to 1.365 (so it would be 1.36 stable, otherwise it drops to 1.34 for some reason), and Memory Tweak to Mode 2 (which it was already at, it puts VCCSA/VCCIO at 1.2 and 1.27, forget which is which) and got no errors in Memtest.

One thing I noticed is that the 256k L2 Cache speed in Memtest dropped from 115 GB/s to 95 GB/s. RAM speed dropped from 29.5 GB/s to 28.5 GB/s.

What other settings was XMP overclocking to cause that difference?

Btw, without XMP, which setting is equivalent to 'all core enhancement' so I can manually enable that?

Updates on my situation in this thread:

https://rog.asus.com/forum/showthread.php?93973-Getting-errors-in-Memtest-with-RAM-at-XMP-(IX-Hero)

There seem to be varying timings coming from the data on the modules themselves via the Asus SPD tool and what it picks up when you actually run it in XMP mode. And there are other people online coming up with different timings for the same memory as well. Here's a spreadsheet showing a comparison of what I've found so far. And while it tends to be more stable in non-XMP configurations, I can get XMP somewhat stable by upping the voltage to 1.45v.

So... is my hardware bad or is the BIOS doing crazy things with the timings? For what it's worth, it completed the 2.5 hour Memtest run in DDR4-2133 mode and DDR4-3600 17-17-17 mode without any errors.

Is Memtest a good way to test all this? It will pull errors if something's wrong, I assume? It seems to have done that so far. I just don't want any false negatives.

Are there any Windows programs which will display DRAM voltage?

[Raad11]

Anyone having inexplicable problems with the XMP settings, try upping your DRAM voltage to 1.45 and see if it's stable. (it won't harm your computer to run it like that for a little while just to see if it works... long term, maybe someone can let us know if that's dangerous)

My ram @ 1.45v hits 48 C while gaming (used to be 42-44 C at 1.35v).

If a memory kit is certified to run at x voltage, then it will work perfectly at x voltage.

Hello

I’ve upgraded my Z270G Gaming yesterday with BIOS 906, but oh boy oh boy … this upgrade was really slowing my PC down !
My new config was blazing fast, but after the bios upgrade my pc was taking forever on the most simple things.
Downgraded back to 801, all things normal again.

Yes. you can use HWinfo64 and SIV64X (these is more complex program is very detail and take time to get use to it) but reads every single senson on the board) Be noted that use these last one to read. I always use 3 programs just to be calm on some times. I find out that HWinfo64 is the best for the ASUS motherboard. Aida64 also can ready ram voltages but you have to activate the reading tap on voltages in the tap to read the volts on the ram! Use HWinfo64.

I updated to 0906 yesterday and so far I have no issues.

Are you able to save oc profiles to memory stick using either F2 or ctrl+F2 or whatever it is?
Bios has freezing issues, mislabeled functions & many issues named in this thread

Just to name a few issues (and this is a fresh UEFI windows 10 pro install no clone drive etc.)
Ram Cache II - (stops randomly with "Incorrect Function" error - had to uninstall.

AISUITEIII - Doesnt recognize my Aquacomputer D5 PWM pump on the Water pump+ header just runs @ 100% (and this is the header designed for PWM pumps!) Many people all with different brand PWM pumps reporting same thing. I would be curious if ANYONE has a pwm pump working on this header.
Spent weeks troubleshooting, had to give up.

Aura - yeah this one is ridiculous! Aura is corrupting G skill RGB Trident Z dimms to where the SPD info gets corrupted and the LED's all go completely dark. Most dont come back with G skills recommendations so for those of you that are like "my RGB memory is working fine" I suggest you prepare to purchase Taiphoon Burner so you can reflash the SPD on all your dimms when it happens or prepare for RMA cause its only a matter of time. Dont believe me do a google search!
At least G Skill has their RGB software in Beta where as Asus doesnt and G Skill just released a new version (not sure if it 100% resolves the dimm corruption issue) but at least they are trying. Note: I have never installed G skills software, only Aura and it corrupted my modules after the first 7-10 days of using it. Thankfully It was within first 30 day exchange period ( I was unaware of Taiphoon burner at that time).

Audio Issues such as bad echo and wierd almost lazer like sounds- may be resolved though but hard to tell cause its intermittant, more game time required and tests.

Cant get any response from Asus in the forums it seems about any issues on Z270 and the driver updates are very sparse, Pretty sad considering nearly the whole line of ROG boards run off the same software and bios and this is a motherboard refresh, shouldnt most issues be worked out from Z170 anyway?

BTW - I did try openeing a ticket with Asus support and the response I got was laughable and frustrating. The "Technician" trying to help me out was probably searching toms hardware for my answers to the AISUITEIII issue cause he wanted me to test things that had absolutely nothing to do with the issue. It was like he didint care and/or know what he was doing.

Mine is a "Strix Z270H".
After the update, my computer was unable to come back from sleep/hibernate state. Every time it went to sleep, it was like the computed died.
Even the power button woudn't work. After turning it off/on, the light went on, but there was no POST, no fan activity.
The only way to get it back working again was to unplug it for a couple of minutes. Some scary ****, as my set was a month old, and it was running smooth).
But what scared me the most was that it also happened when I turned the computer off normally (through Windows), and not only after auto-sleep. I coudn't turn the PC on afterwards without unplugging the system for a couple of minutes. Again, just the green light, but no beeps.

Turning XMP off solved the issue for me (thanks to this thread). It was the only non-default setting in the bios.

Now I just can't use it anymore, as I'm too lazy to flash the older bios version 😛

Can confirm that 0906 works very well for the Maximus IX Formula as well. 🙂

[sdmf74]

Those are strange issues, especially for just setting the XMP. Something doesnt sound right
