Yep

A lot of person was scpetical about R9 Fury.
But the GPU is really great and backed with a fu.cking fast mem ! And the best thing is that I bought them on discount for 240 each.

The key, is the undervolting (-96 mV with AfterBurner) and reducing the max tdp (mine are -48% on Zcash for 410-430 H/s depending of the card, and something like 26 MH/s on ETH with those setting).
Back in the days, I made a video for a guy who don't want to believe in my results : https://www.youtube.com/watch?v=Y86VLJirwN8
I was with Claymore 7 so the perf is less than the 400+ H/s from now. I'll try to record a new one.
But you can see the kill-o-watt meter + the second rig offline (no power draw) + the 5 Fury rig running

The Fury are really good, the only bad thing it's that they are huge and require 2x8pin PCI-E so you have to have a good PSU with a lot of cables.
That is why I was thinking about a card reseller and go for a new one ... but It seems that for now, it's the best.

I'll wait VEGA and the GTX 1170 to see

I am like 95% sure those cards needed a lot less power with CM7 than they need now.
I am running a -96 mV undervolt which gives me 455@200W.

I have reduced the TDP as you suggested but neither hashrate nor the power draw changed. Still at 200W.

Reduced core to 1000 (I usually run 1050).
Hashrate dropped to 435. Power dropped to 170W.
I can see that card lowered core voltage by 0.05V with this move, pretty cool didnt know it can do that.

I think your furies are drawing near 170W right now as well Wink

Still thats an interesting setup, -20h/s for 30W, not bad, thanks for the tip.

Nope, power is limited
They consume the same than with cm7

I'll post a New video

+1 on the Fury's. I have about the same results with the two in my rig. I wish they were still available (or had the $$ to buy more when they were on sale with a rebate!)

I just pulled the trigger on a 580 card. Should be here early next week. I'm a bit nervous because I have read in the forms that 580's don't like to play well with Win 7, Catalyst 5.12, and Claymore. I have two slots open on my OLD OLD Intel Core-Duo MB so I would like to use the 580 in the same rig as my 2 fury's and one r9 290 (which hash out 1150 drawing 600-610w at the wall with basically the setting described above). I also do not want to spend $$ to set-up a second rig.

Anyone have any advice on the set-up? Can it be done?
