Hi, so a few days ago I upgraded my Gigabyte P75-D3 to an AsRock Z77 Extreme 4 (which is used). I want to overclock my i5-3570K. When I go into the BIOS and click on the OC Tweaker tab, I type in a number past 38 for the CPU ratio option, but it just doesn't work. If I type that number back, it goes back down to 38. That is supposed to be the maximum turbo boost for my i5-3570K, right? I don't know if that's normal or what because I'm new at overclocking. Also, I can't change the value of the Intel Turbo Boost option; it looks locked or stuck somewhere. There is also no XMP profile even though the manual says there should be one for my RAM. If it helps, I have an 8GB stick of Kingston HyperX Fury DDR3 running at 1600MHz with CL10. I updated the BIOS to the latest version and nothing changed yet. Maybe the motherboard is broken? Should I return it and get my money back? Or is there just something wrong that needs fixing? Thanks so much in advance. Specs: CPU: Intel Core i5-3570K Cooler: FSP Windale 6 Mobo: AsRock Z77 Extreme 4 (BIOS Version 3.00) RAM: Kingston HyperX Fury 8GB DDR3 1600MHz CL10 SSD/HDD: Kingston A400 240GB/WD Blue 2TB 5400RPM GPU: Asus Cerberus GTX 1050Ti PSU: Gamma HEC-600TE-2WX (600W) Case: Cooler Master RC-K380-KWN1 OS: Windows 10 Pro

Maybe check your computer's details like this: CPU, Motherboard, RAM, SSD or HDD, GPU, Power Supply Unit, Chassis, and Operating System. Can you type a number smaller than 38 and then restart the system to see if the multiplier is set to that number? I think we are talking about the multiplier on the board or processor. Which BIOS version do you have right now?

Lutfij: You should tell me about your computer like this: CPU, Motherboard, RAM, SSD or HDD, GPU, Power Supply, Case, Operating System: Can you try typing a number smaller than 38 and then restarting the computer? I think you are talking about the multiplier on the board or processor. What BIOS version do you have? I tried this before updating the BIOS and my speed got slower but now I will try again. The BIOS version is 3.00 Edit: well, I tried, but now I don't get a lower speed. My turbo speed is actually running at 3.6Ghz on all cores

That is basically a boost, and the turbo speed changes depending on which cores are used. Here is where it says you can get faster speeds with Intel Core processors. We do not tell people about their exact turbo boost frequency per core.

BringerOfTea: That basically means an overclock. When turbo mode is on, it doesn't boost all cores in the same way. https://www.intel.com/content/www/us/en/...ssors.html We don't tell people how high each core goes when it's Turbo Boost on. I didn't know that, but that speed isn't what I need. I want to push the CPU to 4.5 or higher if I can manage it. Do you have any tips on this?

The Turbo boost doesn't work the same way on every core. https://www.intel.com/content/www/us/en/...ssors.html We don't tell you how fast each individual core goes for processors. I didn't know that, but I need a higher speed than that. I want to push it up to 4.5 or even higher if possible. Do you have any tips I could try?

I switched from an Asus P67 to an Asrock Z77 Extreme 4 with my 2600k. It ran stable at 4.8 before I started building it. Now that I put her on the new board, she can't overclock anymore. No XMP support either. Honestly, this motherboard is pretty useless if you want to push her hard.
