It was only the wind.
Guys,

Did you consider to install an addition GPU cooler on card like this
https://www.amazon.com/ARCTIC-Accelero-Mono-Graphics-Cooler/dp/B006DAD8HS/ref=sr_1_9?s=pc&ie=UTF8&qid=1469241260&sr=1-9&keywords=gpu+cooler

That may decrease card T during the dual mining in overclocked cards

Any ideas?

Yeah, and make ROI take longer.

Guys,

What is the point to buy 460 and 470 cards for about the same money as 480, but with lower hashing rate and problem with 4GB memory?

 Availability - though you have a point on the 460 since it's SO MUCH lower than the others, the 470 and 480 are pretty close on hashrate.

 Just finding ANY RX 4xx series card IN STOCK anywhere is a nightmare right now, much less the good ones like the Sapphire Nitro cards.

Guys,

Okay  this is as a service  for miners to decide if a 470 or a 460 works for them.

The 480s are hard to find.

I got some 470's at 185 after coupon

the rig with a pair of 470's runs cooler and quieter  then the reference   480s .


  So  in my case  that is a two rig in my den home theater  quiet is good.

  But if I did all this from the start  I would have the biostar 4 card rigs  filled with 480's.
  I would have 4 rigs of 4 cards giving me about   390-405mh

 I would have the two card rig in my den  maybe with 2x 460's  since it should be very quiet.
 If not it would keep the pair of 470's

I noticed you treat your PC as server. If you treat that with pure miner with 6 graphics cards, would you choose 470 instead of 480?

 I assume or hoped they would do 32 to 36 mh but they do 24 mh most miners will not want or need a rx 460

 If not it would keep the pair of 470's

the 470's show promise   22mh 110 watts 199 and newegg still has a 15 dollar code so a rx 470 at 185 is pretty good.

Hmf ? Maybe that's what he can afford to buy that time. And If I were to choose, I will choose the 480 right? So it will produce more hashing power. Not sure. Maybe he has many rigs and it has different cards .

here are two four card rigs

1  rig with 3 sapphire + 1 diamond reference

1 rig with 2 diamond 1 sapphire 1 xfx reference oc  this is the rig with the g4400 cheap cpu and as of now it is running at 102mh

2 two card rigs

1 is a rx 470 + a rx 480  it does about  about 46 mh
1 is a pair of sapphire rx 470s'  is does about  43 mh


rx 460s come on friday.


that one card is a pair of rx 470's gets 42-43mh

rig5 is two 470s, correct?
yea it is an error I will fix it.
I was able to buy 1 rx 470 at  199.99 and get 15 off with the visa coupon on newegg.

so for 185 the rx 470 looks okay.

my first 460 comes tommorrow

If he runs 4 8gbs cards on the biostar board each card will have a 16x slot at 3.0
but it can only run each slot at x4 3.0 so that's 4gbs per slot
With that half the cards ability will not be used unless that doesn't effect the hashing power of the card.

 Doesn't matter - the card is only using the PCI-E connection for the MOST part to load the DAG file into the card's RAM - then the DAG file just STAYS there for a few days 'till the next DAG file is needed.

 A few seconds difference AT MOST between a PCI-E 16x connection and a PCI-E 1x connection isn't going to be noticeable.


 To be blunt, even a *4GB* card is serious overkill for Ethereum mining at this point, though 3GB cards aren't real common so 4GB is pretty much the "next step up" from 2GB that WILL become worthless mining Ethereum in a few months.


unless you plan to sell the 8gb cards after mining as a gaming rig, then those vrams will be crucial for gaming.... otherwise just a waste of real estate space for ETH mining.

The only probably I see with 8gb cards is the pcie lanes the cpu offers. Most CPUs offer 16 lanes so with 4 cards that 4x per lane at 3.0 that's 4gbs per card so unless the southbridge picks up the slack in the line you won't get the full 8gbs



That's not the way it works. You can use all the 8GB of memory of each card, it's just that the system will utilize it at a (negligibly) slower rate

ahh learned something new today

Trying to think of a good analogy...

Think of computer memory as a bucket, and think of PCIe lanes as a one inch hose for each lane.  Some cards have 8 gallons of capacity (aka 8GB), and some have 4 gallons.  You can fill and drain the bucket with either 1, 4, 8 or 16 one-inch hoses, depending on your setup.  By adding more hoses (lanes), you can fill the bucket faster.  By having a larger bucket (raw memory capacity), you can store more water.

I am not going to update unless i need to for some reason.  Every time I fiddle with something (drivers, updates)  it seems to act slightly different, and sometimes for the worse.

most likely this is correct.  I range from 95 to 101 for the four cards  pool side where it counts  and the average tends to be 98

which is 24 a card  and i pull 590-605 watts for entire system.

I am now trying to get the second rig up  I have an issue I am blue screening with four cards.  will keep trying.


boom second rig is running yeah baby.    four rx 480's  cheaper pentium g4400 psu.

blue screen with AMD 16.8.1
blue screen with AMD 16.7.3
running with AMD 16.7.2

So I now have two four card rigs
 same mobos
 same ram

hows the 460 phil?

All of stuff comes in this weekend so I can't say for sure but looking at from all the info I have now that's the conulsion I came too

for mining all you need is 1 pcie lane per card. it wont effect mining speed at all.

for a mining mobo that needs no risers you would want as many physical x16 slots as possible, spaced out for double width cards. the electrical pcie lane spec can be anywhere from 4-16 per slot on such a mobo.

for example my gigabyte z97x mobo has 3 physical x16 slots, when all are populated they run as x16, x8, x4 electrically.

i do like the m2 ssd bit. less cables etc. and a mining rig wont hammer it so it should run cool.

If he runs 4 8gbs cards on the biostar board each card will have a 16x slot at 3.0
but it can only run each slot at x4 3.0 so that's 4gbs per slot

for a mining mobo that needs no risers you would want as many physical x16 slots as possible (or smaller slots that are open ended so they will take full size cards), spaced out for double width cards. the electrical pcie lane spec on those physical x16 slots can be anywhere from 4-16 per slot on such a mobo.

for example my gigabyte z97x mobo has 3 physical x16 slots, when all are populated they run as x16, x8, x4 electrically.

for a mining rig with risers you can also use the physical x1 slots.

SAP-RX-470-8G-NITRO+ SAPPHIRE NITRO+ RX 470 8G GDDR5 PCI

Whats the going price in the US?



Right now it's 239.99 on newegg with 4.99 shipping

thanks Johnx for the info.

Philip... your 199$ 470 rig, would it be any better than the Nitro version 240$  - performance wise ?

Are you going to run 4 8gb cards? On one motherboard?

I am inspired by Philip's 4 x GPU rig on that BIOSTAR Racing mobo.

I planning to streamline my farm with 4 to 5 onboard GPUs with M2 SSDs.

Enough of those risers and expensive PSUs, and dreaded SSD cables Grin
