ASUS ROG STRIX Z390-E Gaming Issue

[stalkers1]

I have a motherboard ASUS ROG STRIX Z390-E GAMING. Core i9-9900K processor. Memory G.SKILL F4-3200C14D-32GTZ. I updated the BIOS to version 0905. I reset the BIOS to factory settings. Then included only XMP profile. I tried many different BIOS settings (voltages and everything else), and so far G.SKILL memory cannot work on the 3200 MHz XMP profile. G.SKILL does not work regardless of the slots on the 3200 MHz XMP profile. Tested on every BIOS version: 0602, 0702, 0805, 0903 - the same effects.
The memory turned out to run only at 3100 MHz with MemOK turned off.
At a frequency of 3100 MHz passes the Memtest86 test without errors. When MemOK is on, memory starts only at 3000 MHz. I checked this memory on a different platform (ASUS PRIME Z370-A), and it works fine on a standard 3200 MHz XMP profile 14-14-14-34, 1.35V.
I assume that there is some incompatibility of the ASUS ROG STRIX Z390-E GAMING motherboard with G.SKILL F4-3200C14D-32GTZ memory. The memory is absolutely good. I checked this memory on the ASUS PRIME Z370-A board. The memory runs without errors on the XMP profile at 3200 MHz. I wrote to ASUS technical support with a request to release a new BIOS. They said that they transferred my problem to the development and testing department of motherboards. Tell me, is this really incompatibility of the board with a specific memory? And you need to wait for the new BIOS to be released? I would like to overclock this B-Die memory at least up to 3800 MHz, but it does not start even with the standard XMP frequency of the 3200 MHz profile.

I think i have a similar kit to yours, just mine is 8GB sticks

F4-3200C14d-16GTZR

Im running the XMP profile(1.35v) but with low (1.2,1.18v) VCCIO and SA

Try tuning without XMP, my 4266Mhz kit wouldn't work, so I had to settle with a lower timed 3900mhz.

Have you tried XMP II? It will be much more stable than XMP I. I never use XMP I personally.

I personally couldn't get either XMP to work, but that's just because my board hates my RAM at full speed.

I managed to run the memory at 3200 MHz. Memtest86 tests without errors. Here is the sequence of actions:
1. Turn off MemOK on the motherboard
2. It is necessary to change in BIOS:
AI Overclock Tuner: Manual
ASUS Multicore Enhancement: Disabled
DRAM Frequency: 3200 MHz
DRAM Timing Control:
*DRAM CAS # Latency: 14
*DRAM RAS # to CAS # Delay: 14
*DRAM RAS # ACT Time: 34
*DRAM Voltage: 1.37500
CPU VCCIO Voltage: 1.15000
CPU System Agent Voltage: 1.15000
IA AC Load Line: 0.01
IA DC Load Line: 0.01
Save settings. The memory will operate at 3200 MHz. After that, if you reset the BIOS default settings (Load Optimized Defaults) and enable the XMP profile, everything will work.
Until the next memory overclocking. For example, if you set the memory frequency to 3300 MHz, the system will not start again. And if you return the frequency to 3200 MHz, the system also does not start.
In this case, you need to re-change the above settings in the BIOS.

Might have to raise VCCSA/VCCIO, mine won't boot properly below ~1.248v VCCIO and 1.28v VCCSA for my 3900Mhz setup.

I also noticed you're running 2x16GB sticks? Our board works best with 4 sticks due to T-Topgraphy. Also, is your RAM on the QVL? Mine pseudo is (ie in the manual, but not on the website).
