hold 60% of it as ethereum, you can split the rest for like 4 more alts. or go investing to an ICO as long you make an early research about it
Agree! That's a very wise strategy will help to save and multiply your investments.Now yes,all 4 do now 30 MH at nicely 77W in GPU-Z.
GPU-Z 77W is bs if you ask me, check a real power consumption.
Agree,real it is probably a lot higher but at least i can see improvement ,i mean i can count the improvement with lowering the volts.
have you disable the crossfire?
Weird,i flashed 4 cards independtly with modded bios,got 30 mh on everyone,then put all 4 working together,got one 30 and rest 27.5-28 max,same values on freq/voltages/power limit.
Now yes,all 4 do now 30 MH at nicely 77W in GPU-Z.
I suppose i can gain 2 Mh from super tuning ram latency but i lack the time to debug hex code and Heliox is rather on bragging but sharing so i kindly ask The Stilt to make light on this matter and help us all with his great knowledge.
Thanks,will try your rom when have little time available.
Problem is:
1.To reduce power-draw need to lower VDDC.
2.To reduce VDDC need to reduce VCCIO(the memory voltage in Wattman,but that is not the memory voltage,that is the memory controller voltage)
3.To reduce VCCIO the memory frequency will drop ,for 2170-2200 i found 5 cards need 0.92 .
4.0.92 VCCIO will limit the VDDC shown in Gpu-z to 0.9187-0.9250 resulting in 75-80 power draw reported in Gpu-z. ( at 1020 core )
This is all on stock rom which i run 1020 core / 2200 memory and resulting in 27 mh/s on all of my 5 cards . Would be curious the gains tighter timings make,can you test in this conditions too ?
Very happy with my results for RX480 however if additional 2-3 Mh/s can be gained in similar power consumption that would be absolutely awesome

1. True
2. First time i hear that :p and it's VDDCI
You're right about the memory controller though.3. Depends.. not every card is the same
4. Interesting, going to test that out..
At this moment, over 1hr rock solid at 31Mh+
Stats on pool can be seen here: Link
Surely,try to lower VDDC to 0.90 with memory controller voltage stuck at 1 V ,you will see that the vddc reported in gpu-z is 1 V and not 0.90 that you set
4 of my cards will do 1020 core at 0.90 VDDC,one needs 0.925
Please test 1020 / 2200 with better memory timings , as i said on stock rom this is 27 mh/s

Quick question,once custom rom flashed will the wattman app still work?
?
So today i received a payout of 1 ether from pool to my wallet,however i did not receive it in my wallet rather than straight to my exchange account?
This is the weird part,you can see on wallet last transaction was yesterday when i sent a coin to the exchange,but today nothing was send to exchange and 1 ether appeared from my wallet but i did not do anything?
Attached screenshots,maybe someone can explain...?

I see,if at stock then it can be explaing but stock voltage is 1.13+ vddc,undervolting to 0.9 will decrease power consumption dramatically so u should not have more problems when undervolted...
seems like Dual Mining doesn't work with 5 or more 480 cards as the system will reboot itself after a minute.
It's draining power more than mobo can supply even with powered USB riser.
I have a 1200w psu & after a few minutes, it's still crash with just 5 cards slotted in.

hmm this is a huge post, I seem to have killed two MSI gaming 5 motherboards trying to fit six cards dual mining on them.
ALL cards were hooked up USB powered risers, both boards worked fine with 5 cards and then i dicided to consolidate a few other new cards on these boards and poof dead Motherboard after a few reboots like you expereinced, Stupid me I should have realized something was off when the same rig that had worked fine since the 1st of July suddenly started having issues. I've been dual mining DCR from the start so I dont think its an issue with SIA.
Word to the wise only use 5 cards max if with these new cards.
I have another six card rig i set up this morning dual mining i hope i dont come home to another dead board I only have one more spare.
Did u undervolt the RX480 or not? With core and mem @900 mv there is no way you killed motherboard because of RX480 ,i mean at 0.900 VDDC the card will take 70-80W total power,means 35-40-45 max from pci-e slot...
Re: Trying to make a list of the rx 480's hash rate power and settings etc.
Very easy to undervolt and handle the RX480 only using the WATTMAN,no need for additional tools.
Set Voltage to Core and Memory BOOOOTH MANUAL,let memory default voltage 1000 and clock it to 2200.
Then set frequencty to -15% and lower power states last 4 to 980,this is lowest you will get in gpu-z reading too,if you set lower than this you will get 1.0375 in Gpu-z.
With these settings you should have 27-27.5 Mh/s and much lower power consumption and heat

Re: Claymore's Dual Ethereum+Decred GPU Miner v4.7 (Windows/Linux)
Really curious situation,updated to 16.6.2 for having Rx 480 plugged in,installed driver all ok and then i noticed the hashrates:
Configuration: Win 10 64 bit
Video cards : 2x RX 480
1 x R9 390X Sapphire Nitro
1x R9 390X Gigabyte
Rx 480 mine at 27.8 with mem at 2200 the 390X Sapphire does 30.70 stock compared to 30.30 15.12 and the Gigabyte is 26 down from 30 on 15.12.
Why is Gigabyte R9 390X affected by the driver change and the R9 390X from Sapphire not?
