9600kf processor operates at 4.8GHz in BIOS yet functions at 4.7GHz under Windows.
Hey everyone, I'm facing a bit of a challenge. My 9600kf runs smoothly at around 4.7ghz (about 4698mhz) and stays stable at 1.25v. But when I change the multiplier in the BIOS to 48 or 49, Windows can't recognize that speed. Task Manager, CPU-Z, and CPU ID monitor all show 4.7ghz, while ASUS AI Suite displays x48 with adjustable settings. However, the real-time CPU frequency reading only reaches x47 max. I've tried different voltages up to 1.4v, but nothing changes. By tweaking the bus frequency to 102.5MHz, I can hit 4825mhz and get stable performance. It seems like a ratio of 50 in the BIOS might prevent booting. I've seen high temps reach 78°C during testing, but at 4825mhz with 1.323f, it drops to around 70°C under full load. The temperatures on my system are 96°C under Cinebench R23 and 100% load at 9600kf -Asus Prime Z390M with 2x8GB silicon power at 3200mhz (running at 3100mhz). I'm also using Corsair Vengeance LPX 2133mhz and ASUS GTX1070 dual CORSORA CX650 at 2666mhz. Thanks for the insights!
If you keep the BLCK at 100, you won’t exceed 4.7ghz because the multiplier can’t handle over 47. If you changed it to 102.5, you get a higher CPU frequency, which is due to the bus link speed and not just the CPU itself. I’m still using that setting since I don’t have another option. I’ve set the turbo power limit to maximum; it only prevents the CPU from idling at lower speeds without raising the overall GHz. Unless you missed something, that should be fine.
After many attempts and long hours, I discovered the issue. It was the ASUS Multi Core Enhancement. I had to turn it on (disable all restrictions), but I overlooked this step. Now it resets to auto each time I adjust the multiplier. No more fiddling with BCLK. It was frustrating realizing I missed it, but we learn from mistakes. Thanks!
