Topic: Sixth alt coin thread I forgot to mod last thread. - page 50. (Read 80193 times)

Very cool thanks for the link - I bought a bunch of spare ASUS Primes just in case any of ours failed, but they're still sitting brand new all this time lol.

Water cooled GPUs are a waste in a riser rig - they make sense for rigs in a case, or if you use those many-GPU-slot type motherboards due to the limited spacing between cards.
They can clock a HAIR higher (usually) than air cooled due to the better cooling, but generally not enough to make up for the extra cost.

 They CAN be very quiet, with proper design - and some folks need "quiet" to keep their Significant Other happy.

 1070 ti and low-end 1080 both have a 180 watt TDP, but if you run them at their EFFICIENT point around 106 watts - you'd still be pushing it a little with a 1000. Might be OK if you can build the REST of the system to only eat 50-60 watts or so.

 I run 5 cards on a 850 (mostly Seasonic X-850 but I have some EVGA G2 850s around too), but that's with left-over "designed for folding originally" systems that pull 100+ watts for the system while mining Monero on the FX8320E CPU.

 Currently 105 watts on each 1070 ti - you can fudge a few watts around that figure and still see very close efficiency numbers - running +200 core +700 clock on both the EVGA SC and the Zotac Mini models of the 1070 ti.

 1080 at that same power level is very very close on efficiency - they don't DROP as fast at the 1070 ti when you push them harder though.
 +100 core +100 clock on Gigabyte Windforce (2 fan OR 3 fan) or Zotac Mini models.
 1080 tends to cost around 10% more for the "same model" vs a 1070 ti, which gives the advantage to the 1070 ti unless you get a VERY good deal on a 1080 (or you get price gouged on the 1070 ti) as even pushed the 1080 doesn't do 10% higher hashrate.


 The blower style cards should be OK on cooling if run efficiently - their real advantage is for rigs built in a case, where they do a better job getting the hot air OUT of the case than almost any fan-type card does (Sapphire Nitro are an exception there, and the Zotac Mini cards push a lot of their air out of the case as well).

 They also are sometimes on sale for less than any other option, which can make them have a good hash/$ ratio especially if run for efficiency where the cooling isn't an issue.


 My only beef at this point with the ASRock H81 is the socket 1150 - which is getting harder to find CPUs for at all unless you're willing to depend on a used one.
 Consulted on a build with one a week and some back, seems to work well and the only issue was a bad set of risers (which certainly is NOT the fault of the MB).


 There has been wide reports of "ram production shortages" for many months now, and pricing HAS been climbing for a while.
 It also seems to be having some effect on video card pricing of late, though a small one so far.

I know a lot of you are going to (or at least experimenting with) the 8-GPU and up Mobos... but for those of you still potentially in the market for a 4-6 GPU rig, NewEgg has probably one of the best Mobos for this back in stock at the moment at only $70.

I have 2 rigs built on this and they are by far my 2 most stable (vs the other 2 that are on BioStar TB85). I just picked up 2 in case I end up keeping my Vega's & building a GTX rig.

Great info thanks!  This helps me eliminate the 1070 from my search in putting together a 6-GTX rig.  Although, if I go with maybe 3 1070ti's and 4 1080's could I be in trouble wattage wise with only a EVGA 1KW Gold PSU?  I think that would be no problem at all with 6 x 1070 but not sure what the bump in power draw is for those other 2 cards.

Do you happen to have wattage pull for your 1070ti & 1080's at that top 4.4 efficiency #?

Seems Phil and others like these blower/reference style GTX cards... I personally have never owned this style (although i do have 3 Vega 56's but they are still boxed while I decide what to do with them)... but I have heard that they tend to be much louder and have poorer cooling than the versions with 2-3 fans.  Am i missing something with these?  I had kind of narrowed my search to the fan-based ones but maybe that's a mistake.

Yup, RAM has been on the upswing for more than a year now. I noticed this first when the price nearly doubled in the 4 months from when i built my first rig (Sept'16) to my 4th rig in Feb-17.  In addition, I deal with various kinds of memory in my current job, so have a lot of trending data from that as well.  Historically, it's been a U shaped curve with lots of ups and downs, but as noted, the last year plus has been spiking for almost all typed of RAM. it's interesting that even some of the old tech like DDR3 has even risen more (as a %) because there's just not as much of it in the supply chain but there is apparently still demand for it.  Now I heard HBM2 is experiencing really bad supply issues, so likely won't end any time soon.

I finally had time to design and build a frame for the Onda 8 GPU board:



The FS thread is up as well.  

Thanks Phil!

4.3 sol/hash is at stock speeds? does the water cooling help with clocks? i figure i wont run them flat out i will try for efficiency.

im not against hybrid cards i just am not sure how the frame i made would accommodate them. here is a pic:

only the 460 in it until the 2nd power supply gets here later today, the 2nd psu (evga 750) will go to the right of the mobo in the empty area. i could mount them on the front vertical piece maybe.

I buy no name ram from taobao. It was $22usd per piece back when the cheapest was $30 on amazon. It's has no heatsinks, just exposed pcb and memory chips.

But if you are from USA, I think shipping will eat up most savings unless you buy a huge bulk.

here are 2 evga 1070ti hybrids

and an older asus 1080ti turbo

phil, QuintLeo, thanks!

looks like newegg will be a close friend for a bit

Guys, do you know how to get rid of the "code 12" issue ? "not enough resources"

I got it on my personnal computer after the new windows 10 update (creators).
I had 2x 1080TI + 2X 1070 , all 4 running sinces monthes without trouble.
Now one of the 1070 appears in device manager with code 12.

I don't know what to do, it worked well before the update. And I can't free resources (all lanes are needed: USB, SATA, LAN, AUDIO etc ...) as it is a personnal computer and not only a mining rig.

I'm going to try the new nvidia drivers ...

Crucial memory is always at a good price and is great quality (from my experience).  Or get whatever big brand name that is on sale.

this is a good analysis.

If you want quiet gear and go waterblock
    
check the price for

the evga  hybrid 1070  499 usd  https://www.evga.com/products/product.aspx?pn=08G-P4-6178-KR


the hybrid 1070 ti  529 usd  = https://www.evga.com/products/product.aspx?pn=08G-P4-5678-KR


the 1070    does 460
the 1070 ti does 500

both at 115-120 watt settings.  these are the full price cards no 3 year warranty.

 1070 ti followed very closely by the 1080, if operated at their most efficient spot both will hit 4.4 easily with peaks pushing 4.7 sometimes (I don't count "peaks" where the power is temporarily WAY below the set point as those are statistical abberations).
 1080 ti will top 4.1 easily and might hit 4.2-4.3 with a lot of tweeking on a good card.
 1070 struggles to get TO 4 in my experience with several models, but will usually manage it with enough settings work - this specificially includes the Zotac Mini and the Gigabyte ITX.


 When you factor in total system power draw, the 1080 ti closes the gap a hair.
 The 1080 has more "upside" than the 1070 ti when both are run above the "most efficient point" but both drop efficiency pretty fast above about 115-120 watts, and the 1080 normally costs ballpark 10% more for a "same model" card.
 The only advantage to the 1070 is the lower entry price - but it's not THAT much lower than the 1070 ti, and at "most efficient point" for each card the 1070 gives up close to 15% hashrate while only being ballpark 10% cheaper for a "same model" card.

 It also depends on what's on sale and what prices are like in your area.

 GSkill Ripjaws - never had an issue with them and they have better cooling that most.
 Price is usually competative as well.

 Think I have Crucial in a couple machines, but if so it's been reliable enough for me to forget about it (which is a GOOD thing).

Personally I wouldn't file anything for gains unless there was significant money was in my bank account.  Trades, money in exchanges, holdings, etc, I honestly don't think the IRS has the ability to track all that.  Now if you are sitting there all day trading between USD, ETH, and BTC on GDAX then the scenario is a little bit different (especially considering the IRS is getting records from Coinbase), but if you are mining altcoins and trading them, its too murky until you trade them for BTC and then sell the bitcoin.  If you want to document anything, I would say just log your transactions of trading coin for fiat.

I looked at them but I wanted to add a simple category like expense.  Say you pay for hosted miners with BTC I would like to be able to just label that as an expense but I didn't see an option to and email for assistance went unanswered.  Maybe it was just user error but other than that it looked good.  I just went to a manual spreadsheet with the BTC price and amount received and track it manually.

Thanks for the reply guys. I was able to enter the bios so no loose memory or power cables for me.

Figured it out. Had to flash my board to the latest bios.

Scary 3 minutes with NO UPS.

For those with same issue on the ONDA D1800, I made a bootable DOS usb stick and flashed using the tool/bios from the ONDA site.

Good luck.

I use Bitcoin.Tax to assist with my tax reporting. It doesn't solve all problems and still requires work but I would recommend you see if it works for your situation. This tax year will be my fourth year using them.
