It makes no difference where you put it in the command line. As noted in the Claymore README, Nvidia cards don't support undevolting. You can adust the power limit % on Nvidia cards using Afterburner in Windows, which reduces the power consumption target when set at a negative value.

You are wrong. powered risers use between 40W - 50 W each, which is NOT reported in GPU-Z. This is easy to verify in a dual PSU setup like I have where all the risers are connected to the same PSU as the motherboard and the secondary PSU only powers the tops of the cards.

His "570 8GB" should hit 29.5 with alt ethash coins or 29 if he is using windows 10+ Claymore 10 + Blockchain drivers. Also dual mining LBR he should get about 65 mh's with LBR or about 730 with DCR
All he has to do is A. Up the memory clock B. Run Polaris 1.64 and click the Memory Timing button to load the specific memory timing for the card. Nice new feature of the Polaris fork" and he is good to go, Also I would put the following in the Start.bat for his 570   -cclock 1175 -mclock 2050 -cvddc 900 mvddc 900 -dcri 20 (with LBR)   -dcri 25 (with Decred)

LOL, you shouldn't have mentioned these fingers dude, just made my day.

Don't blame machine...you said that you cut your fingers on blades, two times? Wow mate, maybe this is not for you?

Hey man thanks for your feedback seems to have been lost in all the other Vega chat apart from you and Ursul0

So I found the problem on the reporting of temperatures and it was due to Claymore V9.7. After updating all that I was getting the reporting numbers ok and my -tt and -ttli etc seem to have started working

Now I'm running at a steady 25MH ETH and 750 Sia with temperatures of around 65C  for most cards and 40-50% fan with one card running a bit hotter at ~75 and 60-70% fan. Not exactly sure why that is happening but will keep tinkering until I find it... Think it is the second card in and it might be taking heat from first card as well as any heat generated from PSU which is pushed on (will check this by moving PSU away when I have time to run prolonged tests).

So now a few more questions:
1) Should I be happy with 25MH or should I push for 28 on these RX480 Shaphire Nitro+ 4GB(Elpida)? If so how do I do it? I currently have the Anorak Memshift Bios installed (when I had the overclocked Bios it tipped my PSU over 1200 when it tried dual mining). Would I need to go back to standard bios before trying any mods through claymore? What should be starting point and where should I be expected to get to?
2) Does anyone else have problems with their USB Risers? Mine every so often come slightly loose (think USB cable moving it) and it causes a crash. Thinking of putting cable clips on the frame to stop the cable from moving freely between GPU and risers but wondering if actually required.

Thanks

What the heck... is it just me or there are no pages for beta 16 download. I went all the way through my download folder to find a link for AB beta 16 lol
Here you go buddy...when you open it just click on the refresh button and it will start to download.

These speeds are with Elpida 4gpus

Windows 7, Robinhood drivers, AB 4.4.0 beta 16, Claymore miner v10.0
My core clocks  are locked at 1300MHz for both rigs and no matter what I put in AB it won't change a thing, so I change it in batch file with -cclock
My -dcri value is 25 I think it's best for me.

Is ETH+LBC dual mining more profitable with a new v10.0 miner?
Thanks

ETH is not the only one which could be mined I believe.

First will come difficulty bomb and then hard fork. Someone said around 30-40% in total. But yet again we are expecting the price to compensate our much harder work
Those who mined eth earlier will benefit even more. Aaahhh mining is so good .
I started recently, but I am not complaining

I also OC'd gpu, card froze, I rebooted.

Got stuck at mem clock 500 for half an hour, thought i killed it.

You don't have the correct address for your sia pool.

it should look like this.  

-dpool stratum+tcp://sia-eu1.nanopool.org:7777 -dwal YOUR_SIA_ADDRESS/YOUR_WORKER_NAME/YOUR_EMAIL -dcoin sia
