What is CPU VTT voltage?

CPU VTT: Stock VTT voltage defaults to 1.17V or so. The scale runs in 10mv steps, allowing you to add or subtract from the base value. VTT voltage drives the integrated memory controller and the QPI link bus. This voltage will need to be increased as you increase memory frequency and increase BCLK (QPI frequency).

What is Northbridge voltage?

A lot of people can run this in the 1.3-1.40v range depending on the setup. Max safe CPU/NB Voltage is 1.4-1.45v depending on who you ask.

What voltage does CPU use?

The core-voltage requirement ranges from 0.9 to 1.3 V and is usually defined by specific processor performance criteria. The latest core-supply voltage tolerance require- ments are typically ±3%. The presence of large current transients makes the task of delivering reliable processor power even more challenging.

What is NB in CPU?

CPU NB voltage is the motherboard chipset voltage. – CPU NB can increase till 1.3 (hot) and depend on cooler Northbridge. always control temperature below 57C when play game. use hw monitor. note: when you add voltage CPU NB then the CPU also needs high voltage.

What is Vccio and Vccsa?

VCCIO and VCCSA are different parts of intel’s CPU package, whereas DRAM voltage is the power supplied directly to the DIMMs. When the ‘company’ said you would be able to do 1.35V, they were likely referring to DRAM voltage, which can go as high as 1.5V.

What is VTT in RAM?

Series Stub Termination Logic (SSTL) Used in DDR Design It uses one series resistor (RS) connected from the output buffer (driver) to the memory (receiver) and one termination resistor (RT) connected to the termination rail (VTT). The typical VTT voltage and VREF are equal to VDDQ/2.

What is CPU Northbridge Frequency?

Northbridge Speed: The frequency of the northbridge (e.g.: 1,800 MHz or 2,000 MHz). For AM2+ processors, increasing the northbridge speed will boost memory controller performance and L3 cache speed. This must not be lower than the HyperTransport link speed, but it can be raised much higher.

What is HT link frequency?

HyperTransport comes in four versions—1. x, 2.0, 3.0, and 3.1—which run from 200 MHz to 3.2 GHz. It is also a DDR or “double data rate” connection, meaning it sends data on both the rising and falling edges of the clock signal. This allows for a maximum data rate of 6400 MT/s when running at 3.2 GHz.

How do I check CPU voltage?

Open the utility and click Configure Hardware Monitor icon located on the lower-right side of the utility. Select Core Voltage, and click Close. Core voltage value will be displayed on the lower-right window.

Does CPU voltage affect performance?

No, the only reason you increase voltage is to make system stable. Increasing the voltage on a system that is already stable will not increase performance, and a higher clock speed is always faster.

What is BIOS XMP?

Intel XMP (Extreme Memory Profile) allows users to easily overclock XPG memory by modifying settings in the BIOS, by that achieving. even better performance than factory defaults without complex and often risky changes to memory voltages or frequencies.

What is the meaning of CPU NB?

On those CPUs the “CPU NB” is the part of the CPU that contains the IMC, Integrated Memory Controller. This CPU NB connects the CPU cores to RAM and board chipset (NB) through HT Link. HT Link is the BUS between CPU and the board NB=chipset.

What is the benefit of a higher voltage at the CPU/NB?

CPU/NB could help in high CPU clocks, memory clocks stability and uncore stability. But with higher voltage at it you have higher CPU temps, specially in stress. FX can 2500-2700 MHz stable at CPU/NB with voltage 1.25-1.4V (depends at quality of chip).

What is the NB Freq of RAM?

It’s the frequency of the North Bridge on your motherboard/CPU and isn’t really determined directly by your RAM (though it can be/is a part of it). It can be hard to calculate, but essentially it is the NorthBridge Multiplier * Front Side Bus = NB Freq. Similar to how CPU clock speed is determined by a multiplier and FSB.

What is NB Freq and how is it calculated?

It can be hard to calculate, but essentially it is the NorthBridge Multiplier * Front Side Bus = NB Freq. Similar to how CPU clock speed is determined by a multiplier and FSB. That’s my understanding of it, anyway.
