I could downvolt eth only to use ~80w stock clocks, GPU-Z (not at wall, but same card so it's relevant).  ZEC uses similar.  If you downclock to say 1000MHz instead of 1260, you get same speed on Eth (zec suffers), but you can lower voltage another 100mv or more, chopping off perhaps another 20w (haven't tested yet).

Sure you can downvolt to that extreme but your hash per watt suffers past certain points.

Anyways, good luck doing that 2 times a day per card if you're using the RX series if you're wanting to mine whatever is the most profitable.

Sapphire 470 8GB (1750 strap)
Zec 1260/2000 -i 2 1020mv, 82w GPU-Z Avg, 177H/s
Eth 1075/2000       820mv,   58w GPU-Z Avg 27.5MH/s

You can control clocks and voltages with Claymore's miner easy.  Recently Zec and Eth similar profit on Polaris, and Zec is a lot better on 7000/200/300/Fury, so switching on 470 makes no sense.

@xeridea is it easier to control wattage through calymore than through wattmon?

Ive found with wattmon if i go below .96 volt or sometimes even 1.0 core voltage on any card with stock core i crash

You can set voltages and clocks on startup (see thread OP for details).  I don't do it because I don't change clocks, or switch coins often, but many others do.

How low you can go depends on the card.  For finding lowest voltage, it is better to go to wattman, and do a voltage drop based on stock.  Stock voltage can vary from 1050-1156mv, so results vary a lot.  I have found generally 960-1030 is lowest stable at stock clocks.

After you find lowest voltage for each card via wattman, you can set the voltages on miner startup if you switch coins, for winter/summer, etc. Just make sure to get card indexes in right order (-di option can help), or volt all according to the worst card).

Dwarfpool cheating a bit. 
Anytime when you open http://dwarfpool.com/zec page, you'll see in "Last 50 found blocks" that pool found new block with 1-5 minutes back.

But if you reopen this page after 15-20 mins, you''ll se that no block found at that time.

and

are you working on proper support for the RX 480 cards? currently they get 33% less than the 390s in zcash but only 5% less in ETH/ETC

Dwarf might be cheating, I really don't know. But I believe you are misinterpreting the info they provide.

The block listed as "2 minutes ago..." is the one currently being mined. And dwarf very seldom is the pool to actually find the block. Therefore, when you open the page after 20 min, you'll see a similar "4 minutes ago..." for another block currently being mined and probably the previous blocks were found by another pool.

Got it?

Every algorithm hashes at different rates with different cards.

390s is just better at hashing then the 480.

Speeds are normal. You are comparing Apples to Oranges.

Looks like someone released a fake 9.0 beta version. I posted a warning in the YouTube comments to only trust this thread for new releases, but it was removed.

Flag it and bag it  

Edit: Removed link so noobs don't get hacked

Hey Claymore, we did have a vote, and turns out people do want to see what you've got in stock for us !  After next version, you can go to Bora Bora you deserve it

Btw, I can't undervolt in Trixx or AB. Is that because I'm using driver 16.11.x? The voltage setting is locked.

Trixx doesn't let you undervolt 295x2 but AB does. You sure you checked all those basic amd settings in AB? But with AB you are stuck on -100mV when you actually want to go much lower. This is where you need some basic hawaii bios modding.

Yep, checked everything in AB. Using 4.3.0 Beta 14. The Core Voltage (mV) setting is locked when the 295 is selected, but unlocked/usable when the 470 is selected. I might try undervolting in the Claymore command line. Or maybe not (free electricity ).

After much hype and many friends asking me to try out Optiminer; I recently tried Optiminer for Windows v0.6 on my test rig.... but found it no better than Claymore V8.

I maybe wrong and didn't test in detail because I use my 7x370 test rig just for short while but I see many negatives in using Optiminer - including losing the monitoring aspects of Ethman, excellent controls of temperature management, GPU core & memory settings, etc. etc. in which to me are the REAL hidden gem of ALL Claymore miners, on top of the raw blazing speed.

IMHO, Claymore need to unleash v9 (Windows and Linux) and claim who is real king of the hill BECAUSE Optiminer now released his latest version also on Windows. While I begin to understand Claymore's position with SilentArmy issue in v1.1, since Optiminer now has come into the Windows with v0.6 ... I think Claymore v9 (Windows and Linux) is justified.

With all this chatter of a successful hardfork and "state clearing"; ETH going POS soon last night*, ZEC stabilizing at the $60s range, XMR went crazy overnight, ZEC (and XMR) mining use LESS power than ETH mining, the answer is clear..... v9 (ZEC) and v10 (XMR)  

What say you Mr Claymore?

Optiminer is no longer available, so Claymore is still king.

anyone seen this strange issue ?  After i flash a card sometimes with atiflash it shows

0 GPU clock and 0 Mem clock above my new flashed values in GPU-z

I've seen this issue before and fixed it sometimes by removing and replacing the card , howeever this time
when i replace the card I see the same thing. 

Ok now it gets really strange, if i pull that card from the rig, another card in a totally different slot shows the same issue
until i replace the card.

this is windows 10 btw, anyone seen and wierdness like this ? My next step i guess is to re-intstall drivers.

Yes. Remove driver and reinstall...

i got the same the miner shows 385 my average is like 335

Can we expect v.9.0?

It would be great to break 200 H/s from Polaris RX 470 4GB and 300H/s from R9 NANO series.
