Hey guys,
put my new system together a couple of weeks ago and am still in the process of testing out the limits, here are my specs:
Asus Maximus Hero XI WifI - Latest Bios 0903
Intel i7-8700K, pretested @ 5.1ghz, delided by Caseking.de
Noctua NH-D15 Cooler, 2 Fan Setup
Gigabyte Aorus 1080ti 11G
G.Skill Trident Z DDR 4000 GTZSW 2x16GByte
2x Samsung 970 Evo Plus M.2 SSD 1TB
Corsair HX1000i PSU
I have the CPU running stable @ 5.1ghz with LLC of 6, Adaptive VCore of +0.100. Resulting VCore under load with Prime95 1344FFT according to CPU-Z is 1.240-1.250 Volts. Temps are absolutely fine at around 64 C on the cores. This is with memory on "Auto" in Bios which results in 2133mhz.
Yesterday I started testing higher memory frequencies. I went up to 3466mhz, Memory volage at 1.35V, VCCIO and VSA at 1.1V.
Starting Prime I immediately noticed my fans being way louder, and temps are at least 7-8 degrees up above 70 C. Additionally I am looking at package power in core temp of now 150-160 Watts, compared to about 130W at 2133mhz memory speeds.
Additionally the system isn't stable at all at that memory speed, crashed after a few minutes of prime. With memory at 2133mhz I have prime now running for 5+ hours, no crash in sight.
First question about the way higher temps and much more package power ... is that normal? I read and watched a lot of current oc videos on 8700k on Asus mainboards, and this behavious was never mentioned as far as I can recall .. am I missing something in bios settings?
Thanks,
boba
