Completed my new build a few days ago. Specs:
Asus ROG Strix Z270 G Gaming
I7 7700k (delidded by Silcon Lottery)
G.SKILL Ripjaws V Series 16GB (2 x 8GB) DDR4 3000
Samsung 960 EVO Series - 250GB PCIe NVMe - M.2
Asus GeForce GTX 1080 8GB ROG STRIX (STRIX-GTX1080-A8G-GAMING)
Seasonic SSR-650PD Flagship Prime Series 650W Platinum
Raystorm Pro on the CPU, EK block on the video card, BI Nemesis GTX 360 radiator, D5 pump (PWM), Vardar F4 PWM fans
I've been overclocking for a long time. When I built my last system (3570K, P8 Z77-V LE Plus) I just set the multiplier to 42, set the XMP profile for the 1600MHz RAM and left everything else on Auto. Ran fine, good temps. When I built it I didn't have time to dig into the settings and the system was stable so I just left it at that.
What I'm finding is that now, 4 generations later, the BIOS has a LOT more options than the Z77 board had! After installing Windows 10 and whatever hardware drivers I needed I installed Aida64 and other utilities to check the system. Everything looked good so I ran the Aida stress test for about 12 hours with the system at stock settings. Everything looked good. Don't recall what the temps were but I remember there was only about 3°C variation in max core temps.
The BIOS has a "Load CPU 5G OC Profile" so I gave it a shot. It booted into Windows and I started the Aida stress test. Lasted about 6 minutes until I got the "boo-hoo" screen. Made some adjustments to my fan profiles and tried again, this time it lasted for about 11 minutes. Okay so the easy, auto 5GHz doesn't work. Big surprize there. Lets work our way up.
Set the AI Overclock Tuner to XMP, Multi-core Enhancement to Auto, CPU Core Ratio to Sync All Cores, multi to 4.7, LLC to and Vcore to Auto. After about 30 minutes of stress test max temps were in the low 80's and Vcore was running around 1.386, a bit high IMO.
Changed to LLC to 1 and that dropped the temps to the mid 70's and the Vcore to around 1.312. Looking a little better.
Right now I have turned Speed Step to Disabled, LLC to 2, bumped multi to 4.8 and Vcore is still set to Auto. Temps are around 81°C (it's in the garage, ambient is 29°C/85°F) and the GPU test is enabled adding more heat load to the system. Vcore is more manageable now at 1.264. Stress test has been running now for about 10 hours without a crash.
Where do I go from here? I'd like to try to get it running stable at 5GHz. Don't know if the chip will do it or not. Seems stable right now at 4.8 but I'd like to find what the limit is on the chip. Any suggestions?
