This is not going to give you a magic number that will make you stable. How ever they admit that this ratio will shift when changes are made to FSB speed, VTT voltage, and Vcore, and it can shift in either direction based on those changes. E 3,8GHz x7 VBios: I’ve been sharing a dead link because you ninja’d the orginal thread. For example, an E processor ships with a 9X multiplier and a MHz base clockspeed.

What is GTLREF and what has it go to do with me? Part 1
It will only confuse other people. Intel announces the 4-series chipsets.
I’ve been sharing a dead link because you ninja’d the orginal thread. You would then measure again to make sure it is correct and you’d be all set. Let us know your thoughts in the forums.
I should not be able to tweak the individual cores, but what if I can do that, why intep there a big difference between ref0 and ref1? In narrow points of this graph voltage drop due to increased impedance with increased VTT can have a significant effect on stability.
That isn’t to say that voltage moherboard won’t work – it will – there’s just other factors you will see in BIOS’ that are worth learning about.

This is noise margin tolerance, or how far away from nominal you can be with out becoming totally unstable. Overclocking has been progressively getting more difficult since the X chipset was introduced, but it wasn’t until more recently with P and P35 that more advanced options have been released by Intel as the antiquated front side bus runs out of steam. If you’re going to overclock, you first must understand the nomenclature that applies to your processor and motherboard chipset’s architecture.
Basically as the data has to jump from the front side bus domain to the memory domain this window becomes smaller and prone to more jitter, the faster you increase either the front side bus or memory frequencies and gtp. Determines the voltage applied to the CPU’s internal clock generators. They’re TWO dual cores that are on the same chip but they moherboard with each other through the northbridge.
This isn’t to say you couldn’t damage your motherboard. Please don’t resurrect dead old topics. Availability of products based motherboagd the four new chipsets is imminent. It may or may not be a stable value for you even if you set all lanes to itthis would purely be by chance if it is.

The bios should be right, but could be wrong. The settings below also apply to Intel’s X38 and X48 chipsets, mothwrboard in some form even date back several generations.
I’m sure some engineer somewhere had a reason why they created this chart like this, but it’s not based on anything concrete and was not implemented properly it should set all four lanes to SOMETHING. View More Photo Galleries. Because you have an afternoon to waste right?
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 inteo the bios or the voltage the motherboard is trying to apply to a lane. Safe amounts will vary by processor, and even by different steppings of the same CPU, so be sure to thoroughly research before mucking with this setting.
Increasing this can help with overclocking, however it also can result in instability, higher temps, and damage to your CPU. There are some instances, like if you were running VTT 1. 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: If the value is between 0 and mV, then we are lucky because the board will let you do that.
Controls the voltage for your board’s Northbridge minus 1, geek points if you couldn’t guess this one.

Keep going until the cores start failing again and record the value at which they fail. Changes in all the other variables will require an adjustment in GTLREF voltage, and since no automatic adjustment is made, we can conclude that setting can be disregarded.
Win 7 x 64 GPU: Likely between 5 to 20 mV. So you take this adjustment and round up to the nearest 5mV and would then apply that to the lane you had measured, repeating the whole process for each lane. But I’m not going to try and test the limits because I like my hardware in a working state.
