This controls the voltage at the end of the frontside bus on the termination buffers. For example, in one of these motherboards, at VTT 1. Reference voltages on all four lanes are identical; it is only due to voltage drop, which can vary lane to lane, that causes settings between all four lanes to vary slightly. This setting determines what memory divider ratios will be made available. Some other basics you need to know to understand the rest of this post; When I say COMMANDED voltage, this is the voltage value you are putting into the bios or the voltage the motherboard is trying to apply to a lane. To keep the different parts working in sync, some motherboards — such as this one — allow you to introduce tiny delays in different subsystems of your PC. E 3,8GHz x7 VBios:

Continue this process in 5 or 10 mV increments until you become “stable” on all four cores. Some let set lanes individually, all at motherboad, or in pairs. By adjusting the skew you can realign these clock signals and suddenly stability should return again — a good board will have less jitter in its signal generation and finer skew adjustments than one that’s not as good.
I am not sure if they mean full Prime Large runs with this or not. Like the skew settings, this option supposedly optimizes DRAM timing.
This thread is five years old. Speaking to Asus product managers today, they again reaffirmed that just 1.

Please note, that this type of adjustment precludes the ability to ever make adjustments below what the motherboard is attempting to set. This isn’t to say you couldn’t damage your motherboard.
It tells the microprocessor where to filter out the electrical noise in the signals associated with crosstalk and ringback, etc primarily ringback.
Please login or register. What does GPC show, when you manually adjust Refs? I want to add on: They’re TWO dual cores that are on the same chip but they communicate with each other through the northbridge. Dividers available by FSB Strap include: If you wanted to find out what adjustment to make based on ratio increases, or reverse the equation to find out what ratio you are running at for each lane: Intel talks to bit-tech and details its next generation 4-series, Eagle Lake chipsets which should arrive in May.
We recommend By Zergnet. You can calculate some of it, like the GTLs, but gtp all the elements in a pot will still require a considerable degree of discovery.
What is GTLREF and what has it go to do with me? Part 1
Either way setting lanes 1, 2, 3 the same on a dual core should work fine. I have no other tools mothherboard bios to check voltages for vtt etc. You would test this in much the way you would test making increases, HOWEVER, with the 7-Series in order mothwrboard set a value BELOW what the motherboard is trying to set you must modify your motherboard, and that is not covered in this guide.
There is no inteo mode in the bios. Availability of products based on the four new chipsets is imminent. Intel announces the 4-series chipsets. Interestingly enough, I found that 1.

Motherboardd the voltage for your memory modules. For example, in one of these motherboards, at VTT 1. Used in conjunction with the Ai Overclock Tuner, this setting determines how aggressive the board will attempt to run your memory’s latency timings. Naturally curiosity got the better of us so we had to check it out! These lanes available for adjustment in the 7 Series Nforce represent the following: You can see that some Speeds have motherblard much narrower margin than others, this can account for “FSB holes” where the computer cannot run.

The point that gives me headaches are the values that I can set in my bios. This determines the frequency of your RAM. This is especially important for dual cores, who seem to have a more touchy address bus. Also known as Performance Ghl, this setting automatically adjusts parameters of the chipset to improve performace.
