Maximus X Hero with Trident Z 4133 MHz problems!

Level 7
Hello all!
I am a new user in this forum, where I hope to find help for my problem.

In the last days I decided to improve my computer, where I changed the motherboard, processor and memory.
The choice fell on the Asus ROG motherboard Maximus X Hero (without Wi-Fi), the Intel Core i7-8700k processor (has been delid) and the G-Skill Trident Z RGB 16GB memory with clock speed of 4133 MHz (the exact model is: F4-4133C19D-16GTZR ). It is a used set from the first owner who purchased the above-mentioned components two months ago (everything has a shop warranty, except for the processor that was delided - he used liquid metal - Thermal Grizzly Conductonaut, and the processor was already installed in the socket).
Of course, when transporting components, I removed RAM from the sockets, because of security, but once I've installed them back home, the BIOS resets to the initial settings.

Go to the particulars when I want to set the XMP profile for memory (2133 MHz by default), the computer is reset, where next on the POST code reader (Q-Code) there is b1. Yes, code b1, no 61. After this code, the computer resets again 3 times and then pops up after starting the computer that a POST error has occurred and to go to the BIOS settings. When I'm in them, I see that clocking has not occurred correctly and everything has returned to factory settings. I have also suggested an overclocking guide from Der8auer, but this does not give positive results. I also changed the memory of A2-B2 slots. Result? Negative.

I also tried to gradually change the DRAM Voltage between 1.3500v and 1.4000v, and the VCCIO / System Agent Voltage CPU between 1.31v -1.33v // to 2.0v and 2.375v and from the lowest half of 1.15v. but it ended with the same code error.

BIOS version, under which I performed OC data, is 1003 and 1101, but I did not attempt to 0802.

Other components are:
Air Cooling: Cooler Master T4
GPU: Asus Rog GTX1070 Advanced OC 8GB
PSU: Corsair CX750M 750W Green edition (NOT GRAY).
SSD: Crucial MX200 250GB
HDD: WD Blue 1TB
Case: NZXT s340 Window Edition

If I add something to myself, when I chose the day before, the TPU option in the BIOS (TPU 1) alone raised the memory timing to 3733 MHz, but I do not know on what values ​​the other values ​​oscillated + the CPU clock was also increased.

Thank you all for help, and I apologize for my English.

No it doesn't, either search the X299 threads or start your own thread for help

No, the chart was posted out of context from Raja's Kabylake OC guide. Those voltages on X299 are not applicable and way too high. Most CPUs shouldn't need more than 1.1v. 4Ghz on the memory with good timings on samples I've used has needed no more than 0.9v. So a massive difference between platforms.

Try auto, mode, 1 and mode 2

I have the same board (but Wi-Fi version instead) and the same RAM as well.

Updated to the latest BIOS that was posted on the forum today (1301).

Followed the suggestions above and instead of using XMP (since the QVL doesn't show XMP listed for this particular RAM, or any of the G-Skill RAM for that matter) I set AI Overclock Tuner to manual and set the RAM frequency and timings manually (DDR4-4133, 19-19-19-39 2T). I started at 1.35 RAM voltage and was not able to boot. But then I set Tweak Mode to Mode 1 (it was on Auto by default) and booted successfully. However, it was not very stable (programs crashing, BSOD, etc). Upped the voltage to 1.40 and still got a BSOD eventually. Upped it to 1.45 and now things seem to have stabilized.

Is 1.45 a safe value to use 24/7?

I didn't mess around with CPU VCCIO voltage or CPU System Agent voltage at all (they are Auto by default). Should I perhaps experiment with those (maybe they would allow me to lower the RAM voltage a tad?) or should I just keep running 1.45 if it works fine and leave VCCIO and SA voltage on Auto?

You can try tuning SA and IO voltage. Make small adjustments. You may need to reduce these voltages rather than increase them. The ceiling is usually around 1.35V. Some CPUs prefer less.

Should Multicore Enhancement be left as is or should it be disabled? Does having it on impact RAM overclock negatively at all?

1.45 is fine. Dialing out instability on VCCSA and IO rails may help to lower DRAM voltage. Alternatively, relax some of the timings.
