May I ask - what do you need such high voltage for? wth.gif

My experiment shown that at least Elpida 4032 works properly even at reduced VDDCI voltage, it feels fine at 1550 @ 0.925V. I tried to leave default 1.0V setting, but the memory produced errors at around 1600MHz, and I can't say what is the reason. I don't think setting VAUX higher than 1.0-1.05V is a good idea, you will get only excessive power consumption and heat up the VRM2.

reason for 1600mhz errors is memory controller smile.gif you need to increase vcore voltage to keep it stable

I have issues with my TV samsung ku 6070, when i go on a game or just on 3d menu when my card have more than +75mv he goes black, i alt to alt tab on windows for see the screen again, on my pc screen i don't have this probleme, probably cause the hdmi link passing the current electricity, even the voltage switch tv go black

Excuse my horrible english, i use a translator.
A question for those who could kindly answer: how should I set hawaii reader bios on a r9 290 to only have 2 frequencies?
I try to explain better, a just idle the base 300 and immediately "without intermission frequencies", as soon as an application requires more power to have the maximum frequency,
Have in fact only two frequencies: 300 - 1010
I sincerely thank those who want to help

Hey I was curious about doing this since higher core voltage gives me black screens. Unfortunately it seems this page is gone anyone have the doc on the reference rail mod?
