Okay, then, DDR3, let's set it at 1,8V so there is nothing to get confused with. Then try to map the area with voltage readouts

Set DDR2 to 1.8v or? And map what area exactly?

For onboard memory, I already mapped voltage readout points:



They lead to the AS324M IC, which seems to be an amplifier. 8 inputs and 4 outputs:

1 - 4.28v
2 - 4.48v
3 - 2.44v
4 - 10.88v

Just tested with the Mach2 again, there's a small gain, but not in this way it justifies firing up the SS for each bench session. As far as I can see, voltage level is much more important that temperature.

Back to the voltmodding table
