- Enable VID1: Short R336 (original VMOD)
- Increase DVDD to 1.4V: Cut R46 (0R jumper) and replace with 2.94k
- Increase VDD_PLL to 1.2V: Add 27.4k on top of R212 (27.4k || 10k = 7326R)
For reference, the default VDD_PLL is 0.8 x (R211 + R212) / R212, or 1.092V.
Not getting HW errors at 1000 MHz, but I haven't tested long term because I only got my units yesterday. I'm sure 1100+ could be achieved by increasing DVDD using the above method.
It's currently stable (no HW errors, short term) at 1250 MHz (529 kH/s) at 1.821V, with R46 being 14.7k.
Here are my R46 values and measured DVDD:
Resistor Value Resulting DVDD Voltage
4.32k 1.450V
5.90k 1.509V
7.79k 1.581V
12.1k 1.734V
14.7k 1.821V
I think I'll stop there before I damage anything
Good. Thank you!
I edited it a bit for my own clarity. Hope you don't mind.
What is your pool side hash rate - current hash rate and - average hash rate < most important....
