What is CPU Uncore frequency?

What is CPU Uncore frequency?

Uncore frequency is the frequency of the non-core parts of the CPU, ie cache, memory controller, etc. It’s also known as ringbus frequency. Opinions are somewhat divided on how much effect it has on overall performance (if any).

Is i7 920 locked?

The Core i7 920 CPU is multiplier locked (only the Extreme Edition 965s are unlocked), so we’ll have to increase the QPI frequency to get more MHz. The CPU multipliers are still locked but the retail CPUs now offer a wealth of higher performance memory and QPI options which we certainly feel are worth investing in.

What should uncore frequency be?

Typical uncore overclock is 200-300Mhz behind core.

Is uncore the same as cache?

Details. The core contains the components of the processor involved in executing instructions, including the ALU, FPU, L1 and L2 cache. 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.

Does the Intel i7-920 have integrated graphics?

Intel’s processor supports DDR3 memory with atriple-channel interface. For communication with other components in the system, Core i7-920 uses a PCI-Express Gen 2 connection. This processor does not have integrated graphics, you will need a separate graphics card.

How do you set Uncore frequency?

Use the Uncore Frequency Scaling option to control the frequency scaling of the processor’s internal busses. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Power and Performance Options > Uncore Frequency Scaling.

What is core and Uncore in CPU?

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, on-die PCI Express Root Complex, and Thunderbolt controller.
