Heliox - just to update that I managed to get the -175mV working on the new batch of Nanos.
I have not got all 6 cards in a complete setup yet, but testing on 1 card is a success.
I will run it overnight before flashing the other cards.
I will report the kill-lo-watt meter readings tomorrow morning.
As of now, with -175mV rom:
-6mV,1040/300 = 30.3MHs at fans= fix 60%, temps 67-68c
and
stock -175mV,800/300 = 22.4MHs, temps 62-63c, auto fans
I am tempted to try the -200mV rom.
Is it normal that some rigs will have 150 roms and some 175 roms, mixed configs in your environment?
how do you guys mnaage to raise the core on the modded rom cards ? i have several -175 six card rigs and th seccnd i change to core from 800 to even 950 the box crashes
In Windows, you can use the MSI afterburner to raise/reduce the core voltage. The memory voltage is not changeable.
Read my post i said i tried that and it box crashes whenever i change the core from the 800 to anything higer
windows 10, even with a clean install same thing happens.
Do you mean even if you raise the core voltage to higher levels, that does not support the higher core frequency?
core freqency you mean and yes the modded rom cards wont let me raise the core freqency frm 800
stock cards start at 1000 and i have no problems raising it up to 1060
on my -175 rom mod, 800/300 to 1040/300 no problem using Afterburner.
reading the threads here, the only difference from my setup and others is my molex is powered and my risers are also powered.
I could only guess that it maybe power related your issue.
However, others have commented that only powered risers is used (w/o molex) and they can overclock too.
