QUOTE(Ebony & Ivory @ Oct 17 2017, 01:13 AM) Yes. It's normal for Intel chips when you push hard on the 14nm processors. 2 reasons. It's running on 70% of 1250 rpm fans. I didn't apply new thermal paste. I took out my AIO from Skylake i7, I saw some residue paste there, I just fixed it on Coffee Lake. I was lazy to apply new thermal paste because it was 3am in the morning when I installed the new processor and mobo. I'm waiting for new grizzly thermal paste and delid kit. Then only I'll apply new thermal paste. P/S 4.8GHz @ 1.3v is the sweetest spot. With low rpm fan setup and old thermal paste, temperature doesn't go beyond 65c in games.

Is that your best vCore or can it go lower? Did you notice any vdroop (load voltage drops too much from BIOS set)? What's your vCore set in the UEFI BIOS, CPU-Z idle and load? P/S: I'm also waiting for my 8700K from Active Lancing |

I got my 8700K from Active Lansing last Wednesday. |

Officially jump on the bandwagon...
ROG Maximus X Apex and TUF Z370-Pro Gaming are here. Let's start with the Apex First thing to do is of course to overclock the i5-8600K CPU to 5.0GHz (BIOS set 1.425v, LLC5) and run Cinebench R15: CPU score: 1221 cb (7700K @ 5.0GHz: 1087 cb) Currently, I am also testing the LLC in Realbench 2.44 (AVX) to see the vdroop/vdrop. This is just part of the results: LLC works fine for me, vdroop = -0.016v, despite ROG Strix Z370-F users are complaining about 0.08-0.09v vdroop. Also note the core temps, idle @ 57.3C, load @ 85.3C, which are in my opinion a bit on the high side. Cooling is custom loop lowered by a pair of 360mm radiators in push-pull fan configuration. |

All of the ROG Strix models except for Strix-H have recently received a BIOS update to fix the LLC issue. Seems like LLC issue on the TUF series and Strix-H will not be fixed by ASUS. https://rog.asus.com/forum/showthread.php?9...-UEFI-0419-0426 |

CPU: Intel Core i7-8700K (8C/16T) (no delid) Mobo: ROG Maximus X Apex (BIOS 0601) RAM: G.Skill TridentZ RGB DDR4-3200 C16 2X8GB GC: ROG Strix GTX 1080 Ti OC SLI SSD: Samsung 960 EVO 500GB PSU: Corsair AX1200i Cooling: Custom WC Should I delid the chip? |
