You can do much better. Hawaii seems to respond extremely well to tighter timings. Here are two threads to get you up to speed:

You should be able to get 350-380 with a reasonable core clock / undervolt, more if you then decide to push the core.

Bonaire should be closer to Hawaii (290 et al) than Pitcairn. Same idea though, although the core count to bus ratio doesn't come close.

It's just what's been tested to be a known good for the most part. I've seen no performance penalty with the current drivers.

I had an asus rx470 as well. Excellent card. If you aren't using both dvi ports, you can use a compatible rx580 bios to get around driver patching. Mine was hynix ajr and I used an msi 4gb rx580 ajr bios. I found that I got better undervolting stability with rx570/580 bioses vs stock (I'd have displays drop out randomly before).

edit: The asus rx570 bios works as well but still requires driver patching if modded.

sounds about right for stock. you could probably get a bit more unlocking to 1024sp and tightening timings.

Haven't played with timings too much, but am using the 1500 strap with nerdralph's tweaks. Running 1150/1750 @ 920mv/900mv, with gpuz reporting an average draw of 74W. Idle draw is around 22W with 900mv vddci (multi-monitor). Gets around 267H/s. Since the machine's running 24/7 anyway, I figure effective mining consumption to be around 52W + vrm/psu losses.

It can do 300H/s at 1250/1750, and around 310H/s at 1350/1750 (memory bottleneck..). Of course, I haven't really tweaked the timings much, so there may be more to be had (stock bios gets around 265H/s at 1250/1750).

You can flash the asus rx570 bios no problem as well. Idle consumption only improves if both monitors are the same resolution

Edit: Looks like I can do 1150@900mv with the rx570 bios (would be stable before but 2nd display would lose sync). GPU-Z reported draw down to 70W now.

VRMs heating up and losing efficiency (video cards or power supply). Say the rest of the system uses 80w actual (seems like a high number); that's 600-80=520w for 3 cards, or 173w per card. Assuming 80% efficiency, 173x0.8=139w/card.

You should see a nice drop with some undervolting.

damn ddos

This is nice. Going on almost 9 hours without a block now. Blockchain explorer went down a few hours ago as well.

BTC address I've been mining with is now invalid. Any way to move the balance to a different address?

Thank you

Seconds in a day. Should be 86400.

Regardless, mhs as a unit doesn't make too much sense. kwh (3600kJ) came to be because it can allow for easy mental math (e.g. 100w light bulb x 24h operation = 2400wh = 2.4kwh). Otherwise, if your electric rate were simply $ per kJ, you'd have to do more calculations.

For our case of profitability, the current standard of btc/day per mh/s makes perfect sense, other than being long to express. You simply take your hashrate in mh/s and multiply it by this profitability and you get your expected btc/day.

poolwaffle, I don't have access to the btc address I've been using any more, and so can't send you a signed message from it. Is there any other way I could verify that the address was mine and transfer the balance to a different address? It's not a lot, but enough to be sent out on the Sunday 0.001 payout and get vaporized.
