Heliox... have you tried messing with 480s yet?
Anyone have tried undervolting stock 480s?
I get about 24.5MHs per card and would like to save on power a bit more.
I dont mind losing 1-2 MHs if I can lower down watts by at least 50-60watts more.
Anyone tried this?
Where do I get this Wattman utility for RX480. Can it undervolt the 480?

Anyone here have played with R9 Fury ? I already have a R9 Nano but with a discount a can get a cheap R9 Fury ... but even if the perf and spec a similar, the power consumption seems really higher. Does someone have informations about undervolt and power usage of a mining R9 Fury ?
PS :Does the R9 Nano ROM can fit in a R9 Fury ?

With modified bios I can "overclock" ram up to 325 (msi afterburner).. can I move to 500 without modifing bios?

I think the 500MHz is the default AMD R9 nano memory frequency. So you can move to there without problem.

ROM undervolt the RAM, so they are more power efficient for mining ... I don't know if they can handle the 500Mhz anymore after the voltage reduction.

I will overvolt with afterburner.. Correct me if I'm wrong, I don't think the RAM will increase its voltage with clock increase through Afterburner. Only the GPU clock does.

You need the high voltage RAM mod if you want to run 500 MHz. I only run ethereum, with 300 MHz.

Anyone tried Crimson 16.7.2?
Usually my stock Nano can do 22.5MHs
but on 16.7.2 (the latest to fix the 480 power overdraw issues)
the Nanos are now giving me 23.5MHs stock!

I think we're talking about hashrate with Eliovp's Bios which downclocked to 800MHz core & 250MHz mem. At that clock speed, despite upgraded to Crimson 16.7.2, I'm still getting 23.4MH/s hashrate.

Will this modded Rom work on the Sapphire Radeon R9 Nitro 390 GPUs or is this only on the nano version. Would be good if it works on them too or perhaps can make a mod for them too.
