Ok Wolfhere, Ive changed removed the number of processor flag of 2. Ive entered the BIOS directly using the F2 key, but it has only very limited options. The Unified Extensible Firmware Interface UEFI is a specification that defines a software interface between an operating system and platform firmware. I am not able to change Boot settings in BIOS, the related field shows hidden. BIOS setup. View and Download Gigabyte GAX99UD4 user manual online. GAX99UD4 Motherboard pdf manual download. An easy howto guide that show you how to flash update your BIOS on GIGABYTE motherboards. BIOS Setup Utility Access Keys for Popular Motherboards BIOS Access Keys for ASUS, MSI, GIGABYTE, EVGA, Intel, and MoreGIGABYTE Z1. Non K Overclocking Guide. In this quick guide I will explain the process of GIGABYTE Z1. Non K Overclocking. The non K OC is really easy and can be done within few minutes. Few days ago I published a short article about overclocking non K CPUs. Depending on the CPU you can increase the clock between 1. Basics. Unlike K CPUs which can be overclocked using the multiplier, non K CPUs have to be overclocked using the BCLK. X99_UD4P38.jpg' alt='Gigabyte Bios Version F2' title='Gigabyte Bios Version F2' />Pre Skylake CPUs such as Haswell or Devils Canyon could only be overclocked by about 3 5 using the BCLK because the BCLK was still tied to the DMI and the PCIe. However, for Skylake CPUs, BCLK and PCIe have a dedicated reference clock which always stays at 1. MHz no matter how you change the BCLK. In other words You can push the BCLK without worrying about other components. The non K BIOS is skipping some parts of the power management, so there are few things you have to keep in mind The missing power management will not allow to read out any core temperature. However, you can read out the package temperature with the tool HWInfo make sure to stay below 7. C package temperatureNo C States. CPUs will always run full speed and full voltage. No Turbo Mode. No i. GPU. Intel AVX is screwed. Some benchmarks like Intel XTU use AVX and you will have about 4 5 times lower score. As far as I know no game is using AVX so its no problem to use this for gaming rigs. Not suitable for professional usage tho. Avoid high memory clocks. Everything around 2. MHz will be fine. For 2. 47 overclocking and gaming you dont have to worry about any of these points. Pentium, i. 3 and i. CPUs have a low power consumption which results in a low core temperature for 2. As long as follow my guide you dont have to worry about the missing temperature readout. Compatible CPUs for non K OC CPU Name. Cores. Stock Clock. Turbo Clock. Hyperthreading. L3 Cache. TDPAmazon.

Depending on your budget you should only consider these CPUs All of the CPUs should easily reach 4. MHz and a high multiplier is not needed because you can compensate everything with the BCLK. GIGABYTE Z1. 70 Non K Overclocking BIOSFirst of all get the correct BIOS for your board. You can find a list of BIOSes in the table below. After downloading, enter the BIOS and use Q Flash to update to the Non K Version. In the table below you can find the GIGABYTE motherboards that support Non K overclocking using the BIOSes listed below. For more information on how to overclock the Skylake Non K CPUs using GIGABYTE motherboards, check out the Detailed GIGABYTE Z1. Non K OC Guide. GIGABYTE Z1. Non K Overclocking Steps. My setup The CPU clock is a result of the BCLK x Multi. E. g. a i. 3 6. 10. MHz 1. 003. 7. For example a BCLK of 1. MHz. You basically have to change 3 main values to overclock CPU BCLK, CPU Multi Ratio and CPU Core Voltage. While you can always use around 1,3. Volt as CPU Core Voltage, the CPU Multi and BCLK depend on the exact CPU. CPU Name. CPU Ring Multi. BCLK for 4. 50. 0 MHZPentium G4. Core i. 3 6. 10. Core i. Core i. 5 6. 40. Core i. Make sure you have a sufficient CPU cooler. Dont try this with the Intel Boxed cooler. GIGABYTE Z1. 70 Non K Overclocking Example. BCLK depends on the CPU. Check values in the table above. Example with Pentium G4. T to 4. 30. 0 MHz. Enter the BIOSGo to Advanced Frequency Settings and to the sub menu Advanced CPU Core Settings. Adjust CPU Clock Ratio to the maximum value in my case 3. Adjust Uncore Ratio to the maximum value same as CPU Clock RatioGo back to Advanced Frequency Settings  Change the BCLK Frequency to the value you need in my case 1. Load the XMP Profile if available  Adjust the System Memory Multiplier to stay below 2. MHz or lower if you have a memory kit with lower specs e. MHzGo to Advanced Voltage Settings and to the sub menu Advanced Power Settings. Set CPU v. Core Loadline Calibration to High. Go back and go to the sub menu CPU Core Voltage Control Adjust CPU Vcore to 1. Volt. Safe settings and exit F1. Depending on the CPU quality you migh also need a little bit more CPU Core Voltage. Up to 1. 4. 0 Volt is safe to use with sufficient cooling. If the setting is working well you can also try to use a higher memory clock. If you have any kind of question, dont hesitate to ask in the forums Overclocking. Guide Forums. BIOS Screenshots Now boot into windows and test the stability with Prime. K for at least one hour. For a detailed Prime. Guide check HEREThese settings should work for almost all boards and CPUs. If you have problems just let me know in the comments. Video Tutorial 4. How to Access the BIOS on a Windows 1. PCWindows 1. 0 gives you a lot of options you can configure directly within the operating system, but on every computer, there are some settings you can only change in the BIOS basic input output system. The BIOS is the software which is built into your computers motherboard and controls everything from the boot order of your drives to preboot security options to whether the Fn key on your keyboard activates a function key or a media control. Unfortunately, because the BIOS is a pre boot environment, you cant access it directly from within Windows. Download Free Map &Amp. On some older computers or those deliberately set to boot slowly, you can hit a function key such as F1 or F2 at power on to enter the BIOS. However, most computers made in the past four years boot Windows 1. To access your BIOS on a Windows 1. PC, you must follow these steps. Navigate to settings. You can get there by clicking the gear icon on the Start menu. Select Update security. Select Recovery from the left menu. Click Restart Now under Advanced startup. The comptuer will reboot to a special menu. Click Troubleshoot. Click Advanced options. Select UEFI Firmware Settings. Click Restart. Your system will restart and take you to the BIOS.
