Did anyone had this issue try different memory slots? (Long story below), for my mobo, A1 will cause issue, A2, B1, B2 will work. IDK if it is a memory slot issue or defective or whatever, i ship my mobo back to replacement (to vendor, not AsRock RMA) *The memory is GSkill F4-3600C16D-16GTZ, GSkill list this mobo in QVL, although AsRock didn't I'd say it is the same issue, once XMP is enabled, it will not boot. I tried everything i can think, even bought a magnifier just to check bent pin. Because it works fine without XMP profile, so I never bother to try to switch slot. Somehow This is the voltage setting when A1 is inserted: https://i.imgur.com/t7B8T6c.png This is the voltage setting when A1 is NOT inserted: https://i.imgur.com/LzRNTL8.png *VCCSA is 1.25 from auto, accidentally typed it again The reason is A1 reads incorrect setting, cause unknown. But it still won't boot even i copy the working setting over Also there were a few weird things for the package. (So i didn't do the MIB, luckily I can do the replacement because of that..) There is no seal of any kind on the box nor the mobo bag. And the bios version is already the latest 1.3 (let's omit 1.4 for now). Bios version is ok, but i never had any Asus mobo box came with no seal at all. Is this normal for AsRock mobo?

I've only got two ram sticks so they're in A2 and B2. But, if you're noticing weird VCCSA and VCCIO voltages, just change them. If A1 lowers the voltages, higher them. VCCIO should be 1.1 or so (at least for me at 3200 xmp) and VCCSA should be about 1.15.

I'm having this issue with 2x8 Viper 3200's.
I had G.Skill Tridents about a week ago but the motherboard completely crapped out on me. I got the replacement Z370 Extreme4 and ended up discovering that one of my RAM sticks was bad. Instead of waiting another bloody week waiting for new parts, I'm refunding the sticks and just bought these Vipers (PV416G320C5K) and I can't get XMP to work. Nor with Flode's suggestion. With my original G.Skill's, I was able to just toggle XMP and run with whatever stuff was automatically set, however, I was upgraded to 1.4. I did notice that once I got this replacement board, 1.4 was gone. So, my new board is 1.3 and I can't XMP. What do? :c They're in A2+B2 and seated properly. EDIT: This is what everything is set at by default without XMP. DRAM Voltage: 1.350V/Auto DRAM Activating Power Supply: 2.500V/Auto PCH +1.0 Voltage: 1.000V/Auto VCCIO: 0.950V/Auto VCCST: 1.000V/Auto VCCSA: 1.050V/Auto VCCPLL: 1.200V/Auto When it comes to computer knowledge, as an A+ Technician, RAM is a foggy area for me, no less the topic of voltages as well. I'm not sure if these voltages seem too high or too low and what to bump up or down. Edited by DomoSapienXD - 02 Feb 2018 at 4:33pm |

Without XMP those voltages seem normal.. I guess.
The XMP on my ram is 3200 as well, but I have 2x8gb G Skill Ripjaws V. My voltages with XMP turned on are: DRAM Voltage: 1.350v/Auto DRAM Activating PS: 2.500v/Auto PCH +1.0 Voltage: 1.000v/Auto VCCIO: 1.100v/Manual VCCST: 1.150v/Auto(?) VCCSA: 1.150v/Manual VCCPL: 1.200v/Auto Those voltages work for me.. before, with XMP VCCIO was 1.2v and VCCSA was 1.25v. But that caused random freezing for me. Altered them like the guy on page one said, and it works brilliant. |

If anyone here wants to try out the 1.4 BIOS (now pulled from support site) just take a look at the link for the 1.3 BIOS: ftp://europe.asrock.com/BIOS/1151/Z370%20Extreme4(1.30)ROM.zip
Now guess how one might find 1.4, eh? Hint: ftp://europe.asrock.com/BIOS/1151/Z370%20Extreme4(1.40)ROM.zip |

Don't tell people to try that.. there's a small chance that version can cause bricking, due to a change in the microcode for the Spectre/Meltdown issues. Why do you think they removed it in the first place, dude? That, and because it was fairly unstable and had a wealth of other problems. Edited by eballen - 03 Feb 2018 at 7:53pm |

Meh, it's just an option for people with currently unstable systems anyway. As always, caveat emptor.
FYI, ASRock haven't exactly done a great job "removing" it either. |

for me flodes solution helped despite the fact that my voltages actually were to low
