More people are reporting issues with XMP settings with the latest BIOS versions. Visit here: http://forum.asrock.com/forum_posts.asp?TID=12095&title=bios-updates-urgent-note-please-read [URL=http://forum.asrock.com/forum_posts.asp?TID=12095&title=bios-updates-urgent-note-please-read ][/URL]

Board model: X570 Taichi
BIOS version: Both 3.60 and 3.61
CPU: Ryzen 7 3800X
RAM:4 x 8GB Thermaltake TOUGHRAM RGB DDR4 3600MHz

Bios Version 3.4 was stable with the XMP profile activated. With both 3.6 and 3.61 I will either get an 8D post code, or the computer will boot into Windows, and lock up within 30 seconds. Reverting to 3.4 fixes issue.

I hope this can be resolved soon, as I have a 5000 series CPU on order.

Board model: ASRock x570 Creator
BIOS version: V3.00
CPU: AMD Ryzen 9 3900XT
RAM: Corsair Vengeance RGB PRO CMW64GX4M2D3600C18

Notes: Issue no. 1: The RAM will not clock above 2166MHz. My ram is Corsair Vengeance RGB PRO CMW64GX4M2D3600C18 . Other users report XMP profiles working right. In my case if i use XMP profile 7/10 times it will not even post with 8d error code. When it posts and W10 Boots something really weird happens. It will run stable even benchmarks - stress tests at full on Prime95 and Aida64 (even with AMD Ryzen Master Auto OC) up to 2.5 hours tested on all scenarios with no errors. Then at random, it might be task manager or opening a project on Da Vinci Resolve 16 or even Windows Explorer that instantly shuts down the PC. No BSOD, just instant power off. Also tried changing RAM pairs, also lanes, also the other pair that i have available. I even used DRAM Calculator for Ryzen exported my RAM Timings from Thaiphoon Burner to see timings and import them manually on BIOS (for 3600C18). No luck at all.

Board model: X570 Extreme4
BIOS version: 2.80
CPU: Ryzen 5 3700X
RAM: 48Gb (2x8Gb & 2x16Gb) HyperX Predator 3200 CL16 @ XMP

Updated from 2.80 to 3.00 and a lot of problems with the memory speed, suddenly the memory revert to JEDEC speed of 2400Mhz when power up the system. If I enter to BIOS and enable the XMP profile@3200Mhz it works normally and can keep the profile during some time, but after some days it reverts to the 2400Mhz.

I've downgraded the BIOS to the 2.80 version more than 2 weeks ago and no speed issues until today.

Something happens with the 3.80 BIOS version.

It only allows me to put 3000 MHZ with these memories and tried any solution? couple things to try up the voltage a bit .. I have read a lot of users saying Corsair RAM sometimes needs a bit more voltage to run them .. so try 1.375v or similar. try setting memory manually to 3200 instead of XMP make sure you have memory installed in slots A2/B2 if only 2 sticks

solved thanks a lot, activate the xmp profile again and change the ram memory slots to the A2 / B2 and it works with without having to modify the voltage thanks.
