Detailed analysis of Discussion9 9900K benchmark evaluations – initial execution.
Yeah I understand too. I'm using the MSI version. I plan to grab that version and run some more tests. I'm a bit jealous you're hitting 6000 on 5GHz while I can't even reach that. But I'll give it a shot and see how it goes.
Hopefully you have a solid power supply for that 1080Ti. I managed to crack 6000 with a good margin. Also, are you certain you're enabling an all-core boost at 5.1GHz? If not, you should adjust some BIOS settings. My system is actually running all-core boost at 5GHz. It only slows down when power exceeds 165W for 127 seconds (my setting, not the default to stay under 185W) or if the temperature goes above 85°C while using AVX, which I set to 4.8GHz all-core boost (my current setting).
The configurations seem acceptable. Focus should be on the FCLK, which most organizations set to 800MHz. Intel's specification is 1000MHz. I also monitor my ring frequency at 4.8GHz. This is the maximum I can achieve with the present voltage of 1.300. Exceeding this would require a faster increase in voltage compared to adjusting the multiplier for core frequency.
It largely depends on the benchmark being used. The motherboard also has a significant impact. Occasionally, a BIOS update resolves initial problems like excessive voltage spikes when the CPU gets hot, which previously led to boot failures due to overvoltage during auto settings. That happened when I attempted a 5GHz ring frequency. After the update, I didn’t try it again but observed better temperatures and lower power consumption. Running at 4.9GHz caused voltage increases to 1.5 volts on auto, though stability improved and power draw decreased. At 4.7GHz, idle temps stayed under 40°C, and I was able to run Cinebench at 1.375 volts with manual settings.
Upgraded from 2166 to 2400 while keeping original settings and power levels.
I'm using an Enermax Liqmax 2 240mm AIO cooler paired with Corsair ML series 120mm fans, which reach up to 3000RPM. I've tested it with Optane 900p memory drives in RAID0 setups on both Z270 and Z390 chipsets, as well as directly connected via PCI-E X16 lanes on my Z390 board.
