@ dagarair - The Power company only hook up the wire.  You have to pay for the trench work to your panel.  It's stupid expensive for the trench work.  You can call your utility company to mark where all the Gas, cable and stuff are.  Hire some cheap day labor to dig per your city standard and lay the wire for the Electrician. Have the Electrician do the rest.  This will save you a few thousands easily.

@ Tasty Potato Chips - Whatever is crunchiest for you.  Go for it.

@ m1n1ngP4d4w4n - My Day job still pays more, yet I'm neglecting it to follow my Love and Passion which is mining.    Would love to have Shed V3 as V2 is filled up.  Just stupid H.O.A.  I need another house.  =)  

@ flminer - You can use the latest driver right before it is call ReLive.  Never use the latest driver or anything that say Relive or too old where they had Signature issues if you use Mod Roms.

@ CryptoWatcher420 -  Haha, you also don't want to see my monthly bills.  Nothing to get excited when we see income go nuts for a few days or week.  It can drop just as fast like it did in Dec / Jan.  I end up only making a few hundred in gain vs thousands.   I also cashed out all my Eth at crap prices.  Ce La Vie.  Hindsight is always 20/20 but let's hope this LAST!!!!!!!!!!!!!!!  Surely this will invite even faster stupid  high difficulty increases.  

Much appreciated! Am very new to this so could use all the tips I can get 

i use a strix rx480 and im running crimson 16.6 on mine and getting around 306 H/s and its clock speed is 1312 MHz and 2000Mhz on memory and -72 mV and locked fan speed at 55% running the card around 52-54 degrees C im not a video card miner but im working on it to try

same rig is running a r7 240 and r9 380 also

Been following this thread for a while....AWESOME setup and info here! Just got an RX 480 dropped on my doorstep today. Thought I saw in here that the crimson drivers suck. What driver would you guys that know what you're doing suggest for this?

lol I know right, man wish I had as much hashing power even just for a day or two *drools*

30$ ETH, good lord yun gonna rack up those profits   i can already see shed v3.0 coming 

If wishes were fishes we'd all swim in riches -.-

I jumped from GTX 970 to 3 RX 480 in 3-5 months, so right now I am on my way to make a compete 6 cards rig with my personal/work related PC.

Noise is an issue here too. Loudest fan is at 62%, but I will be playing with open case later on. And server psu is nice per cost/wattage, but is louder and should be in a mining shed, imo.

Plus the golden rule - low the cost, so I am guessing I'll take 750~850 PSU unit and complete 6 RX 480 rig. Here Evga 1300 is almost x3 price of my current 750W. I guess I'll have to stick with Sparta sexiness at the moment

And hopefully I'll start new Vega rig by winter ^=^

Hey Yun, did you get the power co to run that cable to you meter base?  I always thought they were responsible to my meter base and if I wanted more Amps they would provide it and or course I was responsible past my meter base.  Oncor as it turns out said nope.  We will run the wire for free to provide more but you need to trench and run 2 x 3 inch PVC pipes and have it all ready for us before we do that.  What did they do for you?

@ yslyung - Keep up the good work my Mad Scientist friend.  Keep us in the loop so we can avoid other potential issues / work around.  Looking forward to hear more about the 1500W, but need to find a better work around for the 1200W since I got 10 of them.  

@ stef_stef - You don't want that one unless you're putting it in a place where noise is not a concern.  It's very loud, there are mods for it but why bother when you can get a compact 4KW beast that is quieter and more powerful.  You can ping Finksy for server PSU.  He carry the 2880 or 2980 (Platinum) that you're looking at as we well as the IBM 4KW which is a combination of adding 2x2KW PSU together via a breakout board.  The 4KW version doesn't come with FANs but Finsy sells the FAN mount and you can choose his FAN which are Super powerful and can handle any temperature.  Because they move a lot of air, they are also loud but a comfortable loud like box fans not annoying high pitch noise like the 2880 or HP 1200W.  They can be use indoor by pairing with quieter fans.  See below link for more detail.  Currently you have to pair all server PSU with either a baby ATX PSU or a Pico.  There will be future breakout board that will be combining everything from 1 server PSU breakout board but I see limitations in ports and higher prices on those option per rig.

@ Cryptowatcher - Keep on messing with it.  Hopefully you an find something good. I gave up last night as it was still screetching even after I did funneling with a strong fan about 4" away powering 6 GPUs.  It will do better if I put it outside instead of under my rig but won't be as sexy of design.  Hope you can discover something better.

@yunn9999 apon getting the hp 1200w psu, im goind to do a little modification to it, gunna try and attempt to cut a hole, I can attach a fan to say the top side to better cool it, depends on how noisey it is for me, none the less will prolly mod it anyways just in case

Yup, I did see those, but it was too much info at once for me to grasp anything I assume you are the one responsible for the breakout boards?

Furthermore, is there a solution (part from using a pico PSU) to power the MB/SSD from the server PSU?

Lastly, I was able to find this page online

http://holybitcoin.com/product/the-beast-adapter-board-2880w/

Is this the place to buy from, or? Is there a EU warehouse maybe?

Thanks!

ah ahahaha ...

BB = ibm bb 2000/2500

what i meant was to drill holes on top of the BB & mount 2 x 120mm fans on top so you can cool them if it fits onto the case, as i thought, most likely it won't fit, too big, same for my rack style/sizes too. maybe u can put the BB in other positions ? yeah drilling on the case would be the minimal damage, way better than cutting a hole.

i am in the process of making HP vertical breakout boards almost identical to the ones i am using now. i hope there will be enough interest, not that cheap as there's a MOQ to fill, the more the cheaper but i don't want too much $ of mine stuck only in a breakbout board but i'm still gonna get a small batch for own use 1st. prototype coming soon.

for the HP, sadly those little high rpm fans are a killer/turn off but atm the only couple of solutions

1) provide CAI. Cold Air Intake or forced cold/cooler air to the intake
2) placement of the psu, avoid being in a hot position/location- airflow direction
3) reduce air turbulence/resistance by clearing the intake path
4) mining rig/rack is at a very cold location

if 1, 2 & 3 is OK, then no need for 4.

the 1500W is a little quieter & lesser high pitch, running now on my 7 gpu test rig. cooler too, prolly less stress & better efficiency. 7 gpu, mixed 470's dual mining getting about 202 mhs/ 2757 mhs on dcr at the wall 1190-1210W.

my personal general rule of thumb is best/at least to have a 20% allowance from the PSU's max output.

tb85 is a direct PnP just small changes to bios when 1st booted up & nothing else needed but for gaming 5 1 extra installation for network after win installation. both works very well.

ok back to work.

@ Tasty Potato - If you're only planning for 1 x 480 rig, I would say sell that 750W and go with 1 EVGA 1300 even if it's used.  Just find one that have 10 year warranty and still hv plenty left.  There are some that are only 3yrs, you can check against EVGA site with the serial # from the seller to confirm.  A quality used PSU will keep your rig stable while keeping cost low.  You should be able to find cheap used one between $110-140.  EVGA support is the best in the industry, they often replace your beat up PSU for brand new ones.  Cable replacements are hassle free.  You can mine for 2 years and get most if not more than your money back due to inflation.  To give you an idea, I purchased most of mine for $80-110 used 2 years ago and 149 new.  They go for much higher now.  It's like free Rental.  You don't want to ugly mess of 2 bulky PSU.   Now if you think your plan is to have more than 1 rig, then PICO and server PSU is definitely a good option as you can upgrade in increments.  The IBM 4KW cannot be matched in power with ATX.

@ Cryptowatcher - I can't recommend this HP 1200W.  I have 10 of them.  Perhaps with YSLUNG board, you can glue a fan closer to keep it cooler which will help with the noise.   However the USA versions, are flat which means getting in between the exhaust n the PCI connector requires a thin fan which are typically weaker and only the bottom 20% will hit the intake.  I'm using a BEEFY FINKSY Fan to keep this little Sucker cool but inside my heat wall test of 95F+.  It will get high pitch noisy.  We would either need a better breakout board or a funnel so that we can funnel 100% of the fan cooling to that path vs 80% being lost.  You still need a PICO with this solution.

@p4n -Welcome and interesting username.

@ ysylung - Not sure what is the BB board?  IS that the HP 1500W?  The IBM 2KW won't fit, I've tried.  It goes a little over where the MB sits and the breakout board extends too far into the GPU space.  I also don't want bullet holes thru the side of my sexy cases.  These HP 1200W PSU are driving me up the walls.  I have a very SEXY design for them, but I must solve this ridiculous high pitch noise by keeping it cooler.  This breakout board I have layout makes it very hard to funnel.   Yeah I agree, I love both the Gaming 5 and the TB85.  I especially like the fact that it's very cheap, plug and play and no emulator required to boot just like the Gaming 5.  That is my only gripe with the H81 as they need emulators but are still my favorite go to board when available as ASROCK offers the fastest RMA services in the States.  

@ stef_stef - Welcome and you will need a Pico PSU or another ATX to power the MB / SSD.  See the picture where I describe Finksy custom Pico which should be available in a few weeks and will be AWESOME!

@Marvell1 - Yeah, this is the reason why I didn't want to sell these board to you or anyone.  I got offers for up to $100 for them and my cost is only $61.  Still it wasn't worth my headache nor would I want to put someone else thru it.  I did keep 5 just to play.   Got a new Toy to play with now rather than waste time on Racing but too busy to power it up.  Support 7 GPU and have LEDs.................hopefully will have time to power it up next week.  


















 

I seem to be runing into this a well , one rig on this board work fine the seccond one is unstable , crashes after a few hours as well, i'm using gen2 for pc-e speed gona set everything to stock and ee what what

I would do a smaller build  with the 750 watt psu.

and do a separate 6 card build.

If you know you are not going to scale to say 20x 6 card rigs  and you may max  at 6 to 12 cards..

plus you have a 750 watt psu.   build a smaller rig first then  if you like mining go for a six card build if you dare.

there is a lot to be said about having 2 rigs vs 1 rig.

A 2 cards and a 4 card

or 2 card  three card rigs.

or a 3 card and a 6 card rig


@ stef stef   you don't want that  server psu on ebay.

you want a kit from finksy  here on this site.

Hey everyone, a beginner miner over here and hope you dont mind if I post my question in this thread.

I just read the entire thread, and I am amazed by how clean and cost effective the server PSU design is.

My questions is, what should be done to a server PSU to power a 6 GPU rig?

http://www.ebay.com/itm/Breakout-Board-w-8-X-6-Pin-to-6-2-PCIe-Cables-for-HP-PSU-ETH-ZEC-Open-Mining-/252604357394?hash=item3ad0649b12:g:f7QAAOSwKOJYHhhc

This breakout board I could find, only has 6 PCIe connectors. How would you power the MOBO, disk and CPU of it?

Would really appreciate an answer to this! Thanks!

i hope a picture tells a 1000 words , LMAO, sorry for the poor editing but i think you'll get the idea, NOT to scale HAHAHA



REPLACE the HP with BB, same position

cooling FAN either on LEFT or RIGHT depending on spacing

on the side of the panel drill some holes for HOT air to escape

might NOT fit nicely or spacing issues but i think you'll be able to figure it out or make some space available or you could . . .

mount 2 x 120mm fan on top of the BB but you'll have to drill holes on the PSU casing voila, you can cool the BB & fit it into the casing

regarding the biostar yes, tb85 has almost 0 to none issues, perfect bang for buck mining mobo. i'll be getting a batch of tb250 lga 1151, in abt 3 weeks or so. i might get few for myself to try it out, rest are for custom rig orders.





so far my fav/preferred mobo(s) tb85 & the gaming 5



happy mining.

this thread is amazing, pure rig porn. Congrats!

Hey, yeah, I tried leaving it at stock clocks, and even tried flashing the stock bios back, but no luck. Leaving all BIOS settings at default also does not fix this issue of the system freezing every 20 hours or so.
The older BIOS worked perfectly though, and this board comes with dual bios so that is a big plus, but its funny how manufacturers keep breaking things in updates.


Haha yeah luckily I only have one of the Z170GT7 , and it doubles up as my primary gaming PC. It does work quite well with 4 cards and the older BIOS (which i backed up, luckily) so i'm going to stick to that for now.
Have been meaning to test out the TB85's over the H81 Pro BTC V2's simply because I see no point in buying a headless dongle for EACH system on a MINING MOTHERBOARD ... I mean what was Asrock thinking, this is V2 for petes sake, what was the point of the revision if you can not fix the single most annoying bug that existed in V1.
Anyways, Hoping for the Biostar TB250 boards to show up soon.

when a lot of the big miners were small miners there wasn't as much as far as options for powering the rigs, 2 psu's is no longer viable option unless you have to do it.
the money you spend on that psu you can pick up a 1200w server grade psu and breakout board for 50 dollars usd on ebay
