Topic: 1080Ti Specific - Best mining option - page 292. (Read 409677 times)

810 sols/s that doesnt sound real.  What was your the add to you core clock?  Most cant go over 100 or 120 at 100% TDP.  Overclocking the RAM does nothing really for mining Zec.  If you set it to 0 instead of negatives it can sometimes boost it slightly.  Sounds like you are remembering incorrectly your values, as stock values will generally bring  the most sols on an Auros card as they don't have much room to overclock and memory doesn't really effect it that much.  I generally couldn't get over 740 on an auros regauardless of settings and I own 3 of them.

ya man, if i could GET a few of those nice Finsky Jabberwoks for the ti builds i would be SO happy, i am thinking of moving more away from the ATX PSU build model as well, cant beat how CLEAN those server rigs look

Server PSUs are very nice as long as you don't have them in a living space (very loud under load). We are using them for most of our rigs on my wife's farm and if you use splitters you can run the GPu and risers all of the same PCI-E cables (use 14 or 16 AWG cables of course).  With the right custom cables and a Pico PSU for the motherboard you can even avoid an ATX PSU altogether, although we have not tried that setup it does look tempting.

I will only be using server PSUs for all GPUs from now on. so much cleaner and easier

each 1200w PSU I have it  power 4 1080TIs or 6 1080s

I think have a 500w PSU powering the MB and risers

all 240v of course

Go with the highest efficiency PSU you can find.

I have two rigs;
2*1080ti on a modern Corsair 80+ gold 850W PSU
1*1080ti and 1*1070 on a 10 Y.O. Generic 750W PSU

The corsair pulls +340W (above idle) when mining at 72% TDP
The generic pulls +376W (above idle) when mining at 72% TDP / 80% TDP (1070)

You're missing the point dude, the point is if you imagine you're buying a 1080 or 1070 for prices above what was stated, you're cutting directly into your hedge. Gamers know what they're worth.

Obviously a single vendor is not what is in question here. Multiple had them, including frys. Why you think Newegg didn't IDK. Maybe you're right but just price matches alone you could have gotten it that low all over, best buy included.

I have the receipt for the 450 i paid...So you're wrong. IDK what you're debating about. I checked after we talked about it.

Max 350 used for a 1080, well under that for a 1070, only reason you could get more is because miners want it.

whattomine added a 1080ti calculator, so just put what values you get in there

But that doesn't include projections on the value of the coins. Obviously getting paid in a coin that has a better risk/reward would be ideal if you're going to just hold what you mine and not exchange.

Today Hush is best by a wide margin on my 5 Tis and 1 1080. Some days nicehash is very competitive and you can hop on spikes so it's an easy choice if you like BTC best. But other days the gaps can be substantive over 10% projected

 Interesting theory, but I NEVER saw them listed THAT low.

 Lowest 1070 on SALE they ever had was $359 or some such for the Zotac Mini, and I don't remember any 1080 under $459 even on sale.



 (edit) never mind, eBay - I don't DO eBay since they started pretty much forcing you to use RipoffPal for payments.

 Again, NOT apples to apples comparison, I was talking about the actual Newegg.com site (though I probably should have clarified that since I was aware Newegg sells on eBay).

 1) Seasonic X-1250 or EVGA G2 1300 should handle your rig without issues as long as you don't push TDP way up.

 3) EVGA, like *most* companies that sell power supplies, outsource the actual manufacturer.
     Their G2 line is Superflower Leadex platform, which is quite good, at least one of their other lines is Seasonic built (GQ series I think?) and are good, don't have enough data on their other stuff to be sure.
     Seasonic, on the other hand, is one of the perhaps dozen actual manufacturers of ATX-type power supplies in the world.

 4) It depends - if you go with 1080 ti models that use 1 x 8-pin and 1 x 6-pin, pretty much any 1200+ watt unit should have enough connectors - the X-1250 and G2 1300 are definitely good for that.
     *HOWEVER* if your risers are PCI-E neither PS will have enough spare connections for 4 of those on top of the cards themselves - but they have plenty of Molex connectors.

     If you go with all 1080 ti that have 2 x 8 pin connectors (Gigabyte Aorus for example), then it gets to be an issue and you might want to consider the dual 750 PS option or a slightly higher capacity single supply that DOES have enough connections - and you might want the extra headroom anyway as 2 x 8 PCI-E cards will likely have a higher TDP than 250 watts (though my Aorus doesn't despite the dual 8-pin connectors).

I'd anticipate to see a steady rise in SPR through July until the helium snapshot, it'll probably look a lot like what happened with Zen/ZCL.

Keep in mind you don't have to run the cards @ 250w. They become less efficient over 150-170w IMO.

I'm powering 4 off an EVGA 1300 G2. Total power draw from the system is probably 800-900w I estimate.

Can someone give me some advice on selecting a power supply for my first rig?

I'll have (4) GTX 1080 Ti cards.  Haven't decided on which PC I'll put it on, probably an older HP with an i3 and I'll run an SSD.  Don't plan on going over four cards on this box, and might stick with four card rigs if I keep building more.

So a few questions:

1) How many watts? 

1200?  That would allow for 4x250 for the cards and 200 left over for overhead and other devices.  Or would you go for higher wattage for better quality, longevity, etc.?

2) Use two power supplies?

Seems like it'd would be easier to source two 750W PSU than one 1500W.  Connect with the adapter cable that allows them to start together.  On the one hand it increases complexity with more things to fail, etc.  On the other it's easier to source and repair. 

3) What brand?

Didn't realize that EVGA was so popular.  I've been around IT for a long time and I guess they're a new favorite, but I remember when I first started seeing them that they seemed to be an "off" brand.  But apparently people think they're the best (or they're paid shills).  Corsair looks good, but I've seen some criticism on some reviews that concern me. 

4) Enough of the right connectors?

Standard connectors: 24 pin ATX mobo, CPU power for mobo, SATA for SSD.
Video connectors:
 - each card has a 6 pin and 8 pin power connector on top, so I'd need (4) 6 pin and (4) 8 pin connectors
 - I've got plenty of new riser boards, version 7.  Qty 6 risers with PCIe 6 pin connectors and Qty 6 with Molex connectors, so I could mix and match or use all of one type.

5) Anything else?

Thanks in advance!

How would I go about computing that? Value of directly mining a coin vs mining through nicehash and getting paid in bitcoin, correct?
Based on the prices of the past 1-2 weeks, how much more could I be earning specifically?

I'll soon have access to a dual 1080ti setup.

my aorus wont clock up more than +140, but as far as cooling is concerned is very good

Are you using nicehash and not directly mining with a pool? If so, id really recommend switching away from nicehash. You could be earning more by directly pooling with nanopool for example.

thing is , only upto a certain point the core overclock would work, after that if you don't give it more juice it won't take it to that clock speed.

Lot of calculations involved if it's worth pushing it to those levels. For example- I see the result right away in games the gain of FPS but for mining, I am not at an advanced level to figure that out yet.

So I've left tdp at 100% and core clock to 190+ , so now it goes to maximum level it can with not drawing more than 100%

is anyone overclocking their voltages?  or is it even worth it? 

wtf is gaco-mod? ))

Unless there is some issue with teh drivers on linux i'd say something else is wrong

That's a pretty big gap

I can get that while playing league of legends at 60 fps on windows 7. From what I can tell my cards aren't that great considering they're gaming x's with two 8 pins

I installed the gaco-mod and I'm earning a bit more with Equihash. I used to earn the best with lyra and lbry, but now equihash brings in more.
