So, this is my third Maximus XI Extreme. I have had to return 2 boards already with a -15% restocking fee because the retailers did not have any ram above 3200Mhz.
These are the kits i have:
F4-4400C18D-16GTRS (This is the new G.Skill Royal so not currently on the QVL)
F4-4266C17Q-32GTZR (This is on the XI Extreme QVL)
F4-4133C19D-16GTZR (Now Sold)
The issue:
I can not for the life of me get either of these kits to boot at any frequency above 3466Mhz, yet i can get them running tight timings at 3200Mhz (14-14-14-28) on both kits.
The bigger issue, is that i upgraded to the XI Extreme from the X Code. My X Code ran both these kits extremely well.
My 8086K's IMC is fine. I purchased a Unicorn chip that runs 5.5 (-2avx) @ 1.462v, 8 hour RealBench and Prime95 stable. This is the same CPU that i ran in my X Code.
Maximus XI Extreme Best Memtest stable:
F4-4400C18D-16GTRS - 3466Mhz 15-15-15-35-T1 @ 1.45v, VCCSA 1.34v, VCCIO 1.34v
F4-4266C17Q-32GTZR - 3200Mhz 14-14-14-28-T1 @ 1.45v, VCCSA 1.34v, VCCIO 1.34v
F4-4133C19D-16GTZR - 3466Mhz, 16-16-16-36-T1 @ 1.4v, VCCSA 1.3v, VCCIO 1.3v
Maximus X Code Best Memtest stable:
F4-4400C18D-16GTRS - 4266Mhz 17-17-17-T1 @ 1.55v, VCCSA 1.15v, VCCIO 1.15v
F4-4266C17Q-32GTZR - XMP Default @ 1.45v, VCCSA 1.1v, VCCIO 1.1v
F4-4133C19D-16GTZR - XMP Profile @ 1.35v, VCCSA 1.0v, VCCIO 1.0v
This should just not be happening. On the X Code i could get them to boot higher than the XMP profiles (but unstable) with T2 timings, but even with T2 timings on the XI Extreme, i simply can't get even a boot at 3600Mhz on either kit, even trying to run them at CL19 and 1.7v. The fact that i have to run the VCCSA and VCCIO so high on the XI Extreme just to get them stable is also crazy.
What's the deal here? I've tried all available BIOS on the support site. I can't imagine 3 boards all having the same issue being a coincidence, and at this point it has caused me to lose some serious $$ as these boards are $800 in Australia.
Unfortunately due to my current setup, i just cant switch back to the X Code as I'm making use of all the header's in this system.
For those who think I'm over exaggerating with purchasing 3 of these boards, here is an RMA request (as the purchase on this site has no date) and 2 purchases from another retailer with dates.
I have been an Asus customer forever. I am lucky enough to be in a financial position that i can spoil myself every time a new generation releases and my card/mobo is always Asus. For instance my recent build (that I'm having issues with) contains the following Asus parts. 1200W Thor, 2xStrix OC 2080 Ti, Ryujin 360 AIO, Maximus XI extreme. I wan't to continue to be a loyal customer but there seems to be some serious quality control issues with the coffee lake refresh boards.
I am happy to provide any debug info to your software engineers if it will assist, as I'm sure not many people purchase ram quite this high end, so not many people would be reporting the issues.

I often find each board series is tuned with the CPUs that are released alongside.
1) What memory stressor did you use to verify stability on your Code?
2) Did you tune the sub timings on the Code, or bother to make note of what they were before changing (this is important when wanting to push frequency this high)
3) Try Maximus Tweak Modes 1 and 2
Any reason why you're using so much VCCSA/VCCIO on one board compared to the other? It's likely you're creating a red herring by flooding these rails with too much voltage, which can be just as bad as using too little
Here is the 4 DIMM kit you are using running on the Formula XI on the 9900K.

Also the board is supposed to be backwards compatible, it's the same chip set, not an excuse for it to not work well with 8th gen processors.

The boards are ‘backwards compatible’ but ‘optimized’ for the newer CPUs. Thats because there are changes to the memory trace layout. Your CPU is likely better off in a X-series board.

I've received PM's stating that Asus is deleting threads about bad Z390 boards, as well as banning those who post them. Just in-case you decide to try and silence me i have already cached this page as well as printed a PDF copy.
If these claims are true, that's super sketchy tactics from a company like this, and if it happens to me, you bet i'll be filing a claim through VCAT, i have zero issues wasting corporations time through mediation and have done so with Samsung and Harvey Norman before. Australian Consumer Law is a mighty fine thing.

As Raja has said, these changes to optimise current gen processors has always been the case as far back as I remember. There are no guarantees with memory overclocking, especially when pushing frequency this far out of spec. It also helps when looking for assistance to answer all the questions asked (doing these things vicariously isn’t easy :D).
If you would like further help dialing in the memory as best possible, post up your current UEFI settings. You can save these as a txt file from within the UEFI.
P.S Threads are only locked or posts removed when they breach forum rules and regulations. For clarity, only two users have been banned recently, one of which was due to promoting dishonest returns on other vendor products.
