Topic: Prebuilt or off the shelf setups for GPU Mining? (Read 1392 times)

Where are you from? Have a look in my signature.

If you're from EU we could talk about it

 390x isn't a good choice for Ethereum mining anyway - uses more power but delivers the same hashrate as the 390 NON-X varients, since it has more cores but both cards are limited by their memory setup.

 Same issue as on the 290x vs 290 NON-X.

 It's also why the Nano/Fury weren't all that great of Ethereum miners, despite their MUCH higher core count than any R9 2xx / R9 3xx series card - they were memory-limited as well AND cost a ton more, though they WERE quite a bit more power efficient.

I build PC's and I can build it without adding the vid cards if you'd like price would be what your looking for and just my time so you won't be charged an arm and a leg.

I used my republic of gamers cross blade for my mining now I just gaming till the new 480's come out.

Let me know and I'll shoot you a price.

 RX 470 blower models should also work.

Which brand of RX 480 did you get?
Or can they all be undervolted?

Hi

In a couple of months, probably Mid October, I'll create something like that. Base of Operations: EU

Custom models, very interesting ones.

you have to use rx 480 on that four card build.

That is a nice Motherboard it looks like, they don't get too hot close together?
What card model do you use?
I have a 390X and a 290X next to each other, 1.5 slot of space, and it increased heat for the 390X by around 20%
Fans on it are at 85% and it's hot enough I can't overclock it so it's going about as fast as the 290X lol.

It's embarrassing to admit, but just for anyone having a "similar" issue.
When I did a system restore from a driver issue, it rolled back the settings for Power Savings.
So Sleep was enabled after an hour, about the same time that it would "crash" yet not respond to a power cycle.
I'm not 100% sure this is it yet, still testing, but pretty sure that would do it.

i am on a tablet  so click and drag link is not happening, but i have a long thread in this section.

i have a four card build the rx 480 solid just works no risers i use the newegg site to order the biostar z 170 mobo.

i reviewed the mobo on newegg website under philip a i gave it a very good review

Thanks all for the feedback.


I tried 3 different brands and also tried the system with just one card(plugged into the motherboard directly) so I ruled that out.  Also it's super clean as it's been in a filtered room, but will try de-dusting them.
RAM and CPU could very well be related, I'm thinking maybe the heatsink isn't doing it's job, but from what CPU-Z reports, it's nice a chilly around 50-60c under load.  Is there a log to file method?  Maybe something happens right before it powers itself down that I'm missing since I can't catch the heat readings.

Tried 3 different power supplies as well.  It's odd because it doesn't seem to be an OS crash, just simply powers itself down.  In Bios I have all OC disabled, and have it to resume on power failure (such as being unplugged from the wall, when you plug it back in it should power up).
It does this, but if I let it "crash" then try this method, it won't power back up automatically, I must hit the power button.  
This is very odd, since I can kill the power from the wall or PSU, then resume power, and it comes right back up.  
But if this "crash" happens, the only way to get it to turn back on is the power button.

Also this happens even when not mining, so that's another odd thing.  I'm using Windows 10, various re-install methods, next is to try Windows 7 I guess, but I hear Windows 7 can only read a certain number of GPU cards for mining, I can't find a solid answer on this for mining.

It was running great for 3 days straight when I first built it, then it just started powering itself off constantly, after running for 1-2 hours.

I use resin/plastic shelves from home depot.  Then I screw the PCIe risers to a 12"x36" flat wooden board.

Each shelf has a wooden board of GPUs.  The GPU are not so close as its not good airflow unless you have auxiliary fans blowing on them.


Anyway, no issues for months.  If I did it again i would put a fire retardant coating on the board.  Maybe epoxy or something...i dunno.

i want to build a few rigs but i need advice on the best stuff to get

NewEgg had some pre-built systems designed to mine Litecoin (Scrypt) with GPUs, but they've sold out on those - the last few sold at a discount to the value of the GPUs+PS alone, so those of us that managed to grab one or more got a good deal.

 3x R9 280X Gigabyte Windforce cards, Evermax Platinum PS, high-end case though the fans were kinda disappointing (turns out up to 3x 120mm or 140mm Deltas fit in the front though for some SERIOUS airflow). I swapped 3x R9 290s into the system and it's been ROCK SOLID since I got the cards upgraded with TheStilt bios on all of them.

Generally though, you ARE going to pay a premium for ANY pre-built system - sometimes a LARGE one.

Try replacing the powered USB riser, or dedusting the slots, testing components like RAM, CPU, disable OC, disable all sleep and low power states, lower the miner's intensity, etc. There are so many things that can be wrong causing your problem.

You can buy pre-built systems on eBay, but you're paying a premium for them... I think that's about it for pre-built.  Some of them sell with and without cards. 

On the motherboard front, the H81 Pro BTC is the gold standard board, but since they've kind of phased it out, people are looking around for an alt.  I'm building a new 6 card rig this weekend using the H97 Anniversary, so it will be interesting to see if that's a good replacement.

I built a desktop with the ASRock H81 Pro BTC motherboard, grabbed some powered 1x-16x risers, and 3 R9 390 cards.
Things were stable at first, but after moving it around it kills the power on it after an hour or so.  I removed all but one card(plugged into the motherboard, no riser) and the issue still happens.
I have a 1600 watt power supply for it.  Tried 110v and 220v hook ups, updated the BIOS, used restore points, different miners, etc.  I don't see anything overheating. Issue remains after a month.

TL;DR
Is there an off the shelf desktop with 4+ PCI slots for mining with these cards, or a merchant that sells GPU mining rigs ready to go?
I don't mind if it comes with some more cards, planned on expanding any way.
I've built dozens of personal desktops, never had a stability issue until this one.
