First of all i want to thank Eliovp for the sharing of knowledge and all the thread participants for the added infos.

I'm on the -175mV rom since 4 days now and all is fine but headless boot won't work.
I need to plug hdmi to monitor and it boots fine
at the moment i have two nanos on usb risers and one on motherboard, one 700W PSU
mobo is H81 Pro BTC and i'm booting lubuntu with claymore's on thumb usb

@Eliovp: i think i have read u have the same mobo and same cpu celeron g1840 did u have issues on headless booting?

also i'm on 312w reading on killawatt for mobo+3nanos with your stock -175mV rom audio and sata's disabled is that good? i thowght i'd go lower with 75watt for each nano i was expecting.

i'm going to try -200mV stock soon.


Thank you again Smiley

good mining to all.

You're very welcome!

Yup, headless booting is an issue as well, but i don't really need it tbh..

Should be around 75-80W per card. It is so over here Smiley

Anyhow, got a new rom, 1.5Mh speed increase per card for Ethereum at the same power usage Wink, in my case, that's 8Mh extra per rig which is a lot Wink

will release it soon!

Greetings!
Really curious how what did you do to the ROM to increase speed at the same wattage?
Increasing the core/mem clock will result in increase power usage, so I think something else?

The Rom drops the core and the memory voltage, without affecting the frequency. So for the same power, higher hash.
Has to be more than that.  Not all cards are equal, some can undervolt further than the rest.
