What should my Uncore frequency be?

Ideally the Uncore ratio should be the same as the core ratio (as it is at stock values) or (particularly in the case of overclocking) higher than the clock ratio to not constitute a bottleneck. On my Intel i5 6600K I set the Core at 46 (4.6 GHz) and the Uncore at 49 (4.9 GHz) – yes, much higher than the Core!

What is Uncore in CPU?

“Uncore” is a term used by Intel to describe the functions of a microprocessor that are not in the core, but which must be closely connected to the core to achieve high performance. It has been called “system agent” since the release of the Sandy Bridge microarchitecture.

What is core and Uncore frequency?

The core and uncore frequency range from 1.2–2.3 GHz and 1.2–2.9 GHz, respectively. The wall power consumption was measured using the Wattsup meter. 3.1 How to Apply UFS. Each component of an Intel processor belongs either to the “core” or the “uncore” part of the chip.

What should Fclk frequency be set to?

AMD recommends users use DDR4-3600 with the FCLK set to 1800 MHz for optimal performance.

What is DRAM frequency DDR4?

This is because DDR4 is double data rate memory. With the default BIOS setting for memory, my DRAM Frequency is 1066.4 MHz. If you double that, you get 2133 MHz. With XMP enabled, you see the DRAM Frequency at 1799.6 MHz. If you double that, you get 3600 MHz.

What does Fclk mean?

All of this occurs in an interconnect AMD calls “Infinity Fabric.” The Infinity Fabric clock speed (FCLK) is configurable and directly relates to the memory clock (MCLK). For Ryzen 3000 CPUs, most will run a 1:1 ratio between FCLK and MCLK, which can be considered “synchronous” operation, up to 1,800MHz.

What should my DRAM voltage be?

We recommend being conservative when increasing DRAM voltage. Increasing voltage too much can damage your system. By default, DDR4 runs at 1.2v, while many memory module kits are rated to run at around 1.35v with XMP. Raise your voltage slowly until your system is stable; we recommend not going above 1.4v to be safe.

How does the Intel uncore work?

Specifically, the microarchitecture of the Intel uncore is broken down into a number of modular units. The main uncore interface to the core is the so-called cache box (CBox), which interfaces with the last level cache (LLC) and is responsible for managing cache coherency.

What is the difference between core and uncore components?

The core contains the components of the processor involved in executing instructions, including the ALU, FPU, L1 and L2 cache. Uncore functions include QPI controllers, L3 cache, snoop agent pipeline, on-die memory controller, and Thunderbolt controller. Other bus controllers such as SPI and LPC are part of the chipset.

What are the Uncore functions of the motherboard?

Uncore functions include QPI controllers, L3 cache, snoop agent pipeline, on-die memory controller, on-die PCI Express Root Complex, and Thunderbolt controller. Other bus controllers such as SPI and LPC are part of the chipset.

What does the removal of serial bus controllers from the uncore?

Removal of serial bus controllers from the Intel uncore further enables increased performance by allowing the uncore clock (UCLK) to run at a base of 2.66 GHz, with overclocking limits in excess of 3.44 GHz.
