Title: Graphics card doubt Post by: jpucela14 on April 06, 2016, 05:53:09 PM Hi miners!
I want to buy mining hardware (Graphic cards) to mine x11 algo. I have mined all my life with ASICS so I'm a little lost with this. Which cards would you recommend me? It's better to get a bigger amount of cheaper cards or getting les cards but more expensive? My maximum price to buy the hardware is 1BTC I already have a motherboard but, can you recommend me some places to buy the cars and the structure where you put them? Thank you so much!

It has 8 GB memory so good for future mining.

1: Viedo card 2: Power supply I think AMD HD 7950, R9 280, 290, R9 380, 390 will be good choice for you. Recommend to buy 80+ bronze, gold or platinum psu to mine more efficiently.

It's better to get a bigger amount of cheaper cards or getting les cards but more expensive? I would suggest against buying at all (be sure to run your numbers first, ROI can get in the years super easily).Most users around here mine upper midrange. As a side note, NV cards have regularly improved kernels and I'm not sure what's the current situation with AMD. In general big card is better than small, just avoid top models.

I always buy the second tier cards. I bought 7950 instead of 7970. I also buy R9 390 instead of Fury.

So I use -100mV to reduce the core voltage.

8-O Gold vs. Bronze or less is a much more paying proposition, there's a LOT lower price premium for the Gold supplies. Title: Re: Graphics card doubt Post by: jpucela14 on April 08, 2016, 08:11:19 AM Platinum vs Gold on power supplies is problematical, unless you get the platinum on a good sale you won't save enough on electric cost to pay for the extra cost as a general rule - and if you do, your electric rate is high enough you probably aren't makeing any money mining anyway. My electric cost is 0,1275 cent of euro x 1kw/hour8-O Gold vs. Bronze or less is a much more paying proposition, there's a LOT lower price premium for the Gold supplies.

A platinum power supply is 2% more efficient. If you use 1250W, that is 25W or 600WH per day or 7.65c per day or 28 Euro per year saving.

As I use a lot of power, so I change to platinum now. Title: Re: Graphics card doubt Post by: QuintLeo on April 09, 2016, 06:40:16 AM Yup, at that electric rate IF you use the full capasity of a 1250/1300 watt supply (or close) it makes sense to go Platinum.
My electric is a good bit cheaper, my Seasonic X1250s and EVGA 1300 G2s aren't anywhere near full loaded, and both of them are bloody close to Platinum efficiency anyway, so it would take me a decade or more to pay off the difference in cost (unless I see the Seasonic X1200 Platinum on a REAL GOOD sale, then I'd have to think about it!). Title: Re: Graphics card doubt Post by: jpucela14 on April 09, 2016, 06:55:34 PM I have never think about how important the PSU could be... Is good to know and take all of this in account for future puchases!!! Thank you

Some times I even use two power suppliers so that it would not run at 100%. |
