Essentials Only Full Version. The lower the number, the better the performance. AaronYuri on October, I partially understand the principles behind GTL referance voltage. Provides a fixed voltage to the memory bus and can presumably help with stability. This determines the frequency of your RAM.

AaronYuri on August, What does GPC show, when you manually adjust Refs?

As mentioned above, the NB goes from x0. If the error happens in the L2 cache then it could fail any core.

Addendum 14th May From what I understood the GTLREF voltage circuits on the motherboard were all the same and each one simply sent voltage to a particular pin on the processor socket, and that on a dual core, the pins for lane 2 and 3 were not used and the pin for lane 1 became core address bus.

The bios should be right, but could be wrong. Obviously for those lanes only as you are still using your original setting on lane 0 and 1. Since the address bus lanes are usually less affected by voltage drop you can experiment with mitherboard less mV on those lanes to achieve higher stability.


Because you have an afternoon to waste right? Intel talks to bit-tech and details its next generation 4-series, Eagle Lake chipsets which should arrive in May. This is of coarse, if Nvidia didn’t pull a programing trick and motherrboard the name in the BIOS when a dual core is detected.

Significant effort on your part is required. Only way to be sure is by using a multimeter. The point that gives me headaches are the values that I can set in my bios.

The auto setting code is broken, as it only sets one lane lane 1 to an arbitrary amount taken from a chart. Sorry for digging this out, but I have a few questions regarding this topic. Even if I go for the “give em all you got” way and set the VTT straight to 1.

Then I tried to play around with the GTL Voltages for a few of the “better” VTT values that went close to 20 gttl but two things seem strange to me: If you’re going to overclock, you first must understand the nomenclature that applies to your processor and motherboard chipset’s architecture. To be more precise bios Ref0 0.


That would be 1. Determines the voltage applied to the CPU’s internal clock generators. Or do the interfere with each other and both have to be on spot at the same time? There is no automagic mode in the bios. Where does this motherbowrd come from?

Likely between ggtl to 20 mV. 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. This thread is five years old. I can spend pages explaining how it works, getting very technical, but most people aren’t interested in this Right now, these values are useless.

Naturally curiosity got the better of us gyl we had to check it out!

What is GTLREF and what has it go to do with me? Part 1

Record these numbers Now continue to increase the values 1 increment at a time. Allows you to introduce a delay to the individual RAM slots to address timing issues.


Here is what I have so far:
