youre prob running 225-250w for that 2100h/s, or about 80-100w more than you would need for 2000, without timing mods (I got 2K @ 837mv.) +50% power for +5% h/r is not worth it - even if your power is free!

Normally 1500MHz needs around 925mV. I don't get those sub 850 numbers. Do you have a watt meter on it? Vddci is also set to <837?

to do the math in my case: 975/925=1.054 and 1.054^2 = 1.11 (+11%), and considering the higher clock, that means power consumption is only ~15% higher then before.

@coinscrow:
Thank you mate, going to try that!

Even 1500MHz is high - ~1400Mhz effective is a pretty efficient spot from all my testing. That combined w/ keeping your SOC <= 1107 MHz, generally allows <= 850mv. My 50% number was based on 1030 vs 837mv - even @ 975 it would be 35%+.

My 56 is plugged into a PDU, but on a mixed rig currently, so hard to isolate. Though I have benched every GPU i own on a meter in the past (w/ multiple algos,) and tend to see 1400/1107 @ 837 eating around 160-170w (64 bios).

As to the 'mem/vddci' setting - since it's really just a vddc floor, in Windows I make it a point to always just set it well below my active state, while in linux I just use ppts, so it's forced by nature of being a table ref.

dear sir, can u share your ppt settings at win with cnr algo? I have some questions ①is it necessary to flash 56 to 64 bios? hynix memory can flash to 64?②what driver are u use?

my vega can not get below 863mv under my setting, stock bios, see the picture i upload, what should i do to lower it's power consume, thanks
