Hello. I change MSI SLI PLUS Z370 to Extrem4, and i see many problems down here. I have BIOS 1.8 Last One on webside. 1. DDR IS/SA - BUG - allredy know this topis 2. Corsair LPX 2x8GB 3600MHz CL18 B-Die - one chip dont start, ok i can buy new one.. But im not happy from that. 3. No Adaptive Vcore CPU- ok i can fight with offset. 4. And at last VCORE! And Watage Consumption! 8700K for start, using Prime95 V29.4 Small FTT Extreme4 - STOCK! 8700K 1,184V 4300MHz = 180-190WAT! IT IS INSANE!! This CPU have only 95W TDP! MSI SLI PLUS - 8700K 1,32V 4700MHz = 180Wat! Asrock Extreme4 - 8700K 1.20V 4700MHz = 220-230Wat! Watage was readed from HwInfo and CoreTemp. Also i check Watage on in wall. Wattmeter show 100Wat in IDLE -> and grow up to 280Wat Prime95. (8700K 1.20V 4700MHz) So its is growing up by 180Wats. In programs i have 15-20wats on CPU and 220-230wats in Prime95 So programs dont show ideal Wats, but it is quiet OK And again lets back to my CPU. My 8700K wasnt stable even with 1,32V @4700Mhz. On Extreme4 its OK witch 1,20V. I still didnt check how low i can go with Vcore, but for now it is minimum -0,12V. PLS TELL ME, what is going on here ?? This is my last AsRock Motherboard? Im statring this Topic on most popular Forum in Poland - PcLab.pl. So U can trust my, im not only one, who will know all that BUGs. https://ibb.co/dh0HZx" rel="nofollow">  https://imgur.com/a/FiE8c  |

You are confusing TDP (Thermal Design Power) with Power Consumption. TDP is the equilvalant in watts of heat produced when running "real world applications" by the cpu. The electrical wattage a cpu can consume can easily be 1.5 times the TDP or much more if overclocked or running a cpu virus like Prime95. My old i7-3770 has a TDP of 77w but would consume near 200 watts when encoding videos. Note: Prime95 is not a real world application, it serves no purpose but to ultra stress a cpu, it provides no real world production or entertainment output, hence a cpu virus imho If the VRM is getting very hot it is likely due to poor airflow over the VRM heatsinks. This is common with improperly configured case fans, made worse with watercooling where there is no cpu fan to blow down across the board or those who want "silent" fans that do not move enough air to keep the motherboard cool under heavy load. ------------- https://www.passmark.com/baselines/V9/display.php?id=99573335296 |

Minciu. please, as is proper when asking for help, list out the hardware that your system is comprised of. Note too, The IC that responds with temps and voltages does not like to be accessed by more than one software program at a time. This can and does many times result in incorrect readings. Please reboot, and using ONLY one software, check what is shown. A pic would be nice. |

" rel="nofollow - So you're VRMs are hot enough to burn. I'll bet they are. You built up a WC and neglected to put a fan over the VRM section of the board. What happens to electrons as they pass through overheated circuits? They req more power to push them. |

" rel="nofollow - Yeap, I need AirFlow on VRM even on Stock 8700K with Extreme4? So why this CPU can go fine with mouch cheaper and poor motherbords? :) I will fight some with Vcore Adaptive/Fixed/LLC, mayby i will find solution. But i think it can by broken by one BIOS for 2 revision of this MB.

I got 215w powerdraw with default voltage settings(1,25-1,4v). 1,23v is stable with fixed mode, but it still draw almost 200w. 90C with coolink corator DS+noctua 140mm and VMR temps goes over 100C with decent air flow. Didn't update bios yet so its 1.30. edit. same components as op -> 8700K(stock) & extreme 4 |

" rel="nofollow - I think I will return to the store my AsRock Extreme4 and never go back to this company again. I will have 100% refund, but i need do this in this week. Today I tried to fight with Voltage, LLC and Fixed vs Offset (No adaptive mode?) On Fixed Voltage and LLC1 it looks almost OK. But i still have to put lower voltage to not burn VRM. On offset voltage i have mexico city :D

Yes, you do when using water cooling. It is obvious. VRM's do not normally get scalding hot. |
