You can find sony87' original rom here: https://forum.ethereum.org/discussion/10299/470-nitro-4-gb-elpida-memory

Two things:
First 470's seem to have a hardlock on 2100 Mhz RAM -my Nitro cards behave like they could blast through that limit with ease.
Does anyone know how to remove the 2100 Mhz limit?

Second> Cards can push both to 31800 Mh/s with curent bios and higher tweaks, bit unstable tho, but I dont like the power draw on them -unless you have free electricity.

If I could remove the 2100 Mhz hard limit on RAM than I could get even higher rate.
Till then, I'm undervolting/underclocking for better rate with lowest power draw

Get low:

Next step: more tweaks less draw

Edit> last two cards are 470s

how much you undervolt your vga till get 71watt powerdraw? it's seem imposible, i have tried it more but if i undervolt the hashrate will be down too, currently my setting 28mhs with 114watt powerdraw.

can you share how to get 71watt without making the hashrate down?
