I increased my 9900k to 5.0Ghz yet Cinebench R15 shows cores running at 3.6Ghz
Hello, I tried the steps on MSI's site to boost my 9900k to 5Ghz, but when I test with Cinebench R15, all cores/threads only reach the base speed of 3.6ghz and the score is low. What could be the reason?

I need to check if Prime95 version 26.6 Blend test works and report the temperatures, either with RealTemp or Hardware Info. I suspect you're limiting performance.
I didn’t run Prime95, but I rechecked using Cinebench and Speccy. The readings were around 88°C on average, with a peak of 90°C.
It seems you’re likely throttling, which prevents reaching the highest clock speeds for optimal scores.
It would help to know what stable 5GHz overclock demands in cooling and core tuning so your 9900K stays cooler.
The 9900K really handles 5GHz well...
What CPU cooler are you employing? Also, it would be helpful to know your overall configuration, including the motherboard, RAM, and power supply.

Tell me what CPU cooler you're using... It would also be helpful to know your setup, motherboard, RAM, and PSU...
CPU Cooler: Thermaltake C5 Untouchable Air Cooler rated at 230TDP
Motherboard: MSI Gaming Edge AC Micro ATX
RAM: Corsair Vengeance LPX DDR4 running at 4400Mhz
PSU: EVGA Supernova 650 G2 80+
Anything above 1.35v will generate significant heat on the 9900K, particularly at 5GHz, making strong cooling essential. A 280mm/360mm AIO or a high-end Noctua NH-D15 would help, though even those might face challenges. Your RAM using DDR4 4400 is also adding to the thermal load due to the integrated CPU controller.
Can you run a Prime95 version 26.6 Blend test and inform me about the temperatures it achieves, such as with RealTemp or Hardware Info? I think you might be throttling... I didn't use Prime95, but I re-ran the tests using Cinebench and Speccy showed average temps around 88°C with a max of 90°C.

It would help to know what stable 5GHz overclock demands in cooling. A solid cooler is essential—this includes CPU cooler, case airflow, and VRM cooling—to avoid throttling and achieve the best performance with your 9900K.
