You could try re-mod and re-tuning your bios card. Which strap are you copied? also which PBE you are using to modified your card bios? if you are using the old version of PBE, it means you have copied the strap manually. PBE 1.6.2 will copy strap 1750, PBE 1.6.6 will copy strap 1500.

Every people have their own considerations, the best for them isn't mean the best for you. You can ask here and get a few input, use it as one of your considerations, but still, you need to do your own research. What you ask here, isn't easier to answer. The decisions are yours.

First of all, Same as the other people here suggested to you, clean your previous driver using DDU.

Then download Radeon Software Crimson ReLive Edition Beta for Blockchain Compute, use this driver version.

If you plan to modify your GPUs bios, do it yourself with original bios. Remember, it not safer doing something like this:


Note: If you are Windows users, will be better using windows 10 last updates.

Price 3 gigs cheaper than 6gigs, if 3 gigs mining ETH for 2 years again isn't safe but for mining Equihash not problem.

because of Equihash different from Ethash that needs to load Dag file using VRAM from that's processed.

yes, I have experienced this incident. I found the cause such as the down voltage electricity, the quality of the PSU cable, and the quality of the power connector in the riser.

at this points,you must detailed the management. because the mining process many complicated moreover you use other people money. you must think about durability RIG such GPUs, what coins should be mining.

CMOS (complementary metal-oxide-semiconductor) for storing bios settings.

means to reset the BIOS settings to its default level.

how to clear CMOS:
1. Unplug and plug your CMOS battery to Motherboard
2. through jumper switch.

If I right those PSU come with PCIe 8pin (6+2), 2x 6pin, the rest 1x8 pin (6+2) and 2x6pin.

if you plug 1 more GPU, the 8 pin (6+2) would be powering your GPU, The Riser using 6pin.

NVIDIA : Relatively silent, power efficient, better thermal management.

AMD: Cheaper Price, Excellent in Ethash.

but for now, conditions price GPUs AMD or NVIDIA very expensive.

you can do it with 850W if forced but its position is not safe for all performance, could be Rig restarted itself or crash due to lack of power. and you have to take into account the power consumption for supply to 4x Riser.

for example for SATA Connector you need around 55W, mean if 4x55 W = 220W.

you can under-volt all GPUs but it still doesn't safe conditions.

The difference has in the creator of the algorithm itself, the algorithm can be used for which hardware like can CPU, GPU.

at the variable measure hash rate like Cryptonight algo using by H/s (hash per second), Ethash Algorithm using  MH/s (Megahashes per second).

and which coin can be mined by the algorithm itself like Scrypt algorithm using (DOGE, LTC coins etc), the Cryptonight algorithm (XMR, BCN etc), Ethash Algorithm (ETH, ETC coins).

Yes, from the miners, they are greatly benefited, for the producers they produce more and competition out the latest series. of their sellers hope the profits can buying.. Lambo

RAM : normal 2-4 W, peak 10 W Conditions
Celeron : 51 W (Series G)
SSD : 4 W(1 TB)

many thread asking same question. I hope in the future you can calculate how much needs powering.

Let's play :
first, something missing here, you didn't inform us your CPU spec like (Processor, RAM, HDD/SSD)

because every part different power consumptions depend on the type, like processor Celeron VS i7.

But 1070 has TDP 150 W and you ask :
for 3 GPUS
3x150 = 450W, remaining 300 W enough for other parts powering (Proc, RAM, Riser Power, HDD/SSD).

Depends on how many GPUs installed for your RIG?.

If still available after installing GPUs, go on using PCIe cable it will be better.

But if PCIe cable didn't enough to powering GPUs and Riser SATA to 6pins it's ok but Remeber use several rail from your PSU.

Make sure your Riser powered with max 75 W since normally PCIex16 will supply 75 W max for a card.

Sir, maybe this is what happened,

The seller's mindset (but not all sellers like this): How much stock of goods, how many demands, Hold until prices rise to the moon. then sell

not enough better using 850 W/1000 W/1200 W.

Let's calculate:
-GPU RX470 has TDP 120 W. RX570 has TDP 120 W, total = 240 W.

-RAM , when used normal condition 2-4 W, when peak power consumption 10 W. Assume take peak power consumption 10 W.

-Processor i7-4790 has TDP 84 W

- SSD has power consumption 4 W (this case, samsung 1 TB when write random activity).

- not yet another parts not calculated.(like 2xUSB RISER ).

things like this can't be in 100% correct prediction. many groups in telegram or other social media who have analysis to hold the coin which one to keep and which coin will increase the price.

for example the case of ETH coin price, no one can predict 100% correct that ETH coin price will be like now. April 2017 price 1 ETH $45.

conclusion, only you alone can decide.

You can try measuring power consumption by using a power meter such as A killing watt meters.

you can compare how much desktop power consumption is when it's on and used in mining, and without mining.

each desktop has a processor that has a number of different 'thread'. the number of 'thread' determines the resulting hashrate number which is certainly directly proportional to electricity consumption or so-called hashes / watt.

then my opinion:

yes, if the desktop is used for mining, I think there will be the additional cost of power consumption.

Although, the price of 1070ti is a £100 difference but you can get 3 GPUs. so price 1070 ti cheaper

income/month 1070ti greater than 1080ti

1070ti more energy efficient than 1080ti and I suggest buy 1070ti , great in mining Zcash, Neoscript.
