Somebody can please help me for making my old PC into a gpu mining rig.

My PC specs.

Motherboard : gigabyte GA-M68MT-S2
2 PCIE slots : 1 PCIEx16 & 2 PCIEx1
Processor : AMD Phenom ii x6 1045T
Hard drive : 1TB HDD
Ram : 4gb
PSU : 200W

I am going to buy 2 asus rog strix gtx 1080 ti OC will it work on my built ?
Do I need to modify or completely upgrade to a new system ?
Also can I go with 1 gtx titan volta instead of 2 asus strix gtx 1080 ti oc ?

You might need a bit more ram I would upgrade that if you are running 2x 1080 TI, and also you will DEFINITELY need a better PSU for those GPUs. 1080 ti is very power hungry. As for the mobo I'm not too knowledgeable. Worth a try at least. With mining most of the time it's a grueling path of trial and error.

Another thing I should tell you is to check out mining.help . I found this website incredibly helpful when i first started. Setting the hardware up is the easy part its the software part you are going to be really asking the questions for down the road. I spent atleast a week and a half learning how to mod my AMD gpus (you wont have to do this in your case because nvidia), learning how to get all my gpus recognized, which miners to use and how to configure and even still some algorithms bring the BSOD.

In the end after reinstalling everything and following that guide step by step I got my rig working pretty quickly. It's centered mainly for AMD GPUs but most of the guide will apply the same for Nvidia. Best of luck.

Any type of mining is hemarage for deveice.

mining axe with inspiron580 on 85khps with cpuminer-multi)) your gpus will do even better i think) https://arcpool.com/site/mining

Since you have 3 slots, you might as well buy 3 cards to maximize because you are going to have to pay quite a bit for a new PSU. 

I recommend this PSU if you decide to update to 3 cards later but a 1000W or 850W PSU should definitely work if you are only using two cards.

Definitely a new PSU and of course throw in some capable GPU's, I'd start with 1060 's while you are starting out. It's a myth that you need gaming or mining motherboards

I use a crappy matx motherboard with one PCIe x16 and two PCIex1 and a cheap PCIe expansion card I easily run 6 cards. You don't need top ram or processor either mining is GPU intensive not CPU, RAM or disk intensive.

I run my rig with Asrock EXTREME 4, 990FX chip with 5x PCIE onboard and FX6300 processor, very good setup however CPU might be some electricity-eating so you would mind use other one.

Regards

I have the same CPU in my desktop with 8GB ram and Windows 10 x64.  Here are some hash rates:


Go to either whattomine.com (http://whattomine.com) or www.coinwarz.com (http://www.coinwarz.com) to see your profit.  I am currently mining VRM at vrm.mining-pool.ovh (http://vrm.mining-pool.ovh).  Looking at switching to AEON.

Yes, it would work but you get PSUs 80+ gold/platinum, 1080'tis has TDP 250W. I suggest you buying PSU have 1000W or 1200W and RAM 4GB is enough

you need at least 600w for 2 1080TI's, and at least another 150w for the rest of your system. For cushion and stable run, a psu of at least 850 W with minimum Gold rating is recommended for your proposed setup.

Yes, you can. Need increase ram to 8 gb and ofc new PSU.

What cards ? max 3 on this mobo, so it can be, for example 3 1080.

I run 4 card on my 10 years old PC

It should work but you need to make sure the motherboard is at least PCIe 2.0 or higher.

I had an issue with very old motherboards where the GPU wouldn't detect because it was PCIe 1.0.

Upon turning on the fans just spin at 100% and nothing detected in bios.

Well, I think it could work but if you want to upgrade to a new system its your choice. And moreover,A ten years old PC is good; most people uses it cause its much stronger than the recents. You should also consider upgrading the RAM to something higher for compatibility sake. And another thing, what coin do you intend to mine with it? Cause some coins can be quite selective.

Before setting up my rig I am doing as much research as I can. And I found upon setting up a cheap mining rig.

A cheap hp server psu 1200w and the manufacturer may have been made it very stronger so as to run 24/7 for server pc.

Also we can find online the conversion kit from psu to 12 pci 6 pins power slots with cables from 6 pins to 6+2 pins for the 1080ti 8x2 pin power slots

This 1200w psu will be the second for just to power up the gpus and risers while the primary psu 200w will power up the motherboard.

I hope this setup will be a cheap and a better one ?

-Motherboard seems just fine
-You'll need one x1 to x16 USB riser for 2 graphics cards (one will be plugged in at x16 and one will be plugged in at the riser)
-Processor seems fine
-Hard drive is fine
-RAM is fine
-PSU is useless. Throw it and buy a new one with 1000 watts power supply.
-Those 2 GPU's should work just fine on this built (after the required changes)
-Complete upgrade isn't required
-No, go with 2 GTX 1080


Buying that HP server PSU will be a mistake. It'll consume way more power, I'd never recommend it. Combination of two PSU's will work too, but then again, will consume more power as this all will lose power efficiency big time.

Buy a good PSU once, it'll provide you much more comfort.

I think it should work

2 gtx 1080 is better than 2 asus strix rog 1080 TI oc version ?
As 1080 is only 8 gb and 1080 ti is 11 gb or my motherboard doesn't support 11gb ?
Even my mining speed will be slow with 8gb when compared to 11 gb ?

Mining on every computer is possible, but in this case you have to reinvent some parts because you can very easily break down this equipment.

I'm using my old desktop for mining. MB is ASUS M3A-H/HDMI, CPU is AMD Athlon II X3 445 and i have only 3 GB DDR2. This is a temporary solution so I'm using only one GPU. Hash rate is absolutely the same as when I'm using AMD A10 with 8 GB DDR3.

I have an AMD Athlon X4 with DDR2 memory running 2x 1080ti's   ;D

Lucky you :D
For some unknown reason I cannot make it work with two risers. One works perfectly, the other one also, but when i try to use both a the same time it won't boot. After I clear CMOS I can enter BIOS (only when I try for the first time) but that's all.

I don't think so there'll be much of difference in hashrates between the versions & between 8 GB/11 GB, just make sure it's 1080. If I were you, I'd get the cheapest 1080 available. I've both, RX 480 8 GB and RX 480 4 GB, there's a very slight difference in hashrate (like 7%), while I remember there was a good difference in price. So this memory doesn't matter too much IMO. But yeah, if you're planning to overclock afterwards, you might have to explore more about the versions.

I'll warn you again here though, do NOT go with HP server power supply until and unless you've extremely cheap electricity.

Went for the cheaper 1080's, no regrets here.

The speed difference between 1080's and 1080ti's is A LOT.   In equihash you get 480H/s from a 1080, and 735H/s on a 1080ti.

This. Obviously have a go, but sometimes the new MB for 80quid seems like good value after 2 days of swearing. Sometimes old boards are great tho, so worth a crack.

Good that you mentioned it. Seems like my comparison of RX 480 8 GB & 4 GB was not applicable on comparison of 1080 and 1080ti. I actually have zero experience with nvidia cards, I've always remained in amd.

You do not need 8gb ram for 2-3 cards, just a waste of money.

4 GB of ram should be plenty for most mining usage on 2 cards - I've had systems that mined OK with *1 GB* of RAM, but they were single-card systems.

DEFINITELY need a power supply upgrade.
How big depends on specific usage - if you set the cards to run at efficient point around 60% TDP / 150 watts each (for most 1080 ti models) then you might be able to get away with a good 500 watt, but in general I'd recommend somewhat bigger than that.

You might want to SERIOUSLY consider downgrading to a lower-power-usage dual-core or even Sempron 145 single core CPU, that Phenom 6-core was a serious power hog IIRC.

 Nvidia 1080 to 1080 ti is a MAJOR difference in cards - it's more comparable to RX 560 to RX 570 (not QUITE as big a jump, but that's the right BALLPARK).

 RX 470/480/570/580 are VERY small variations to the point that ram SPEED often makes more difference than the actual GPU model in mining usage.

You can mine on any PC, in which you can stick those cards that you can mine. It is just necessary to choose the optimal power of the power supply. In your case, 850 watts is the minimum (better the gold specification). Everything else will go as it is.

suggest update the GPUs then you are good to go.
Have fun

Nope - I "retired" quite a few PCs 2 years back when I moved that would NOT mine at all - but they were running AMD K5 series CPUs, did NOT have PCI (much less AGP or PCI-E) slots on most of the motherboards, and were pushing close to 20 years old at the time.

I JUST retired another pair of machines - AMD Palomino-series Athlons, 32 bit systems with no PCI-E at all though they DID have AGP - in THEORY one could mine on those, but AGP and PCI (not-E) cards were at best VERY VERY limited on CUDA cores or AMD Stream units and ALL of them were very old versions that probably nothing current supports or would work with.

You PROBABLY can mine with any 64-bit CPU based system, but some of the very oldest of those may not have PCI-E slots and the CPU will be very poor performance even on CPU-only coins or on Monero.

Anything from the last 12 years or so though should be usable - some of the Sempron Socket 754 systems I bought back in late 2006/early 2007 timeframe have been used to mine on and have A PCI-E slot.

It does not depend on the computer. It all comes from your video card or processor, but in those days there was nothing really good for mining, so do not even waste time on such nonsense, it's easier to sell this computer on metal

If it has a pcie slot then it can mine. One notable exception is polaris cards with old CPU's, they still work together but you can't install 64b win 10 on old CPU's and polaris cards need win 10 for drivers or you'll be stuck with bad hashrates.

You need a new PSU obviously...

Also why do people buy 1080Ti's for mining is beyond me

1080 ti very close on both efficiency and hash/$ on MANY algorithms with anything else even as a bare card - don't ASSUME that all mining is Ethash (ETH/ETC/ECL and such) where the 1080 is a bad choice.
It also offers higher rig density than any other option that is affordable (Titan V is NOT affordable) for which some folks are willing to pay a small premium vs "max efficiency" cards.

Can also depend on what is AVAILABLE the last 3 months - sometimes you buy what you CAN get, not wait a month or two to sneak in a buy on something you would prefer IF you get lucky.

It's an old machine but could possibly do the trick. First of all, get rid of that PSU, buy decent one such as a Corsair Gold/Platinum if you are going to spend that much for GPUs, secondly, upgrade the RAM if possible. Since you have 1 x16 slot and 2 x1, you could possibly use GPU risers.

I'd rather wait a month or two instead of waiting for years for ROI. At no point have 1080ti's been anywhere close to being the most cost effective mining card, even with limited options, even considering electricity cost, it just doesn't work out.

 PSU 200W is precious little even for one of two asus rog strix gtx 1080 (250W each) you are going to buy. You need 600W minimum, better 800W (to pull peak ratings) or your power block will cut one with a smoke.

A GTX 1080 ti is VERY cost effective on merged folding - probably the best card to use for that - *IF* you have a folding-optimized rig.

On ZEC, they're very close on hash/watt vs ANY member of the GTX 10xx family when all are operated at "most efficient" settings, and they've usually been very close on a "rig-level" basis on hash/$.

THE most cost effective, no - but not all that far off it and some folks are willing to pay a small premium for the higher rig density they offer (and lower time spent managing those rigs on LARGE farms).


The numbers probably vary if you're not in the US - some areas might charge more of a "premium" for the higher-end cards than we usually see here.

They are cool cards for sure but for mining purposes, the only thing that matters is cost efficiency and they fail pretty hard there.

If i were you i would invest in cloud mining ....

thanks

No, they do NOT fail hard on cost efficiency - at the RIG level they are pretty much to a TOSSUP with any other GTX 1070/1070ti/1080 mode - unless you are defining "fail pretty hard" as "more than a percent or two difference".

Sounds like you got high rig cost problems. With the plethora of mining specific hardware available these days, anyone can get their slot cost down to at least €25, including power.

Its around 15% worse than a 1070 in terms of cost efficiency which in turn is worse than the 1060 and not to mention all the polaris cards. I'd call that failing pretty hard.

You can use the aging pc if you see that all of the requirement in mining are in there,

1. Is there an extra pcie slot for another gpu? (atleast it have 2-3 pcie slots onboard)
2. Upgrade your PSU atleast 500-750w for 3gpu

2gb of ram is okay, you can add it from virtual memory

and the rest is not necessary.. Goodluck!!

$25 WITH power is NOT a reasonable number, unless you are using total JUNK for power supplies or used parts - but even the BARE CARD figures on the 1080 ti keep it close to the other GTX high-end cards on cost efficiency unless YOU are getting charged insane amounts for the 1080 ti compared to the others.

SHOW ME a system that manages $25 per slot with NEW parts - I really would like to see that.

Then show me what kind of crazy rip-off pricing you're seeing on 1080 ti cards vs 1070/1070ti/1080.

Ain't my job to build your rigs for you but its easy enough - get one of them 8 slot integrated cpu/ram mining boards from a random chinese estore, add 2 midrange PSU's and a little ssd and you're done. 1080ti's can be had for ~€700 and 1070's for ~€450 over here. Comparing to a 1070 is silly though when there's piles of ~€220 polaris cards clogging up every local auction site and the prices keep falling. Was pretty much the same price relationship when the card prices were still high, just around 50% higher.

2 650 watt power supplies from a QUALITY maker alone are going to be $200 give or take $20 - which already uses up your $25 per slot claim.
There is also the VERY POOR COOLING of those 8-slot motherboards to keep in mind, unless you're running water-cooled or hybrid MORE EXPEN$IVE cards you're going to have MAJOR issues with high heat on anything past a RX 460 or GTX 1060, or you're going to have to add a lot of high-power fans (and MORE power draw to run them, as well as the cost) to keep the GPUs even close to cool - adding to the "per slot" cost of the rig.

I don't see $220 Polaris cards around here, the lowest I've seen for decent mining GPUs in the last 9+ months was $200 for one seller with a couple used R9 290 cards (and a phone number they NEVER got around to answering, so I don't know if the posting was legitimate) while the Polaris cards have been listing for MORE than Newegg NEW pricing the past month ($339 lowest current offering on Newegg, a Sapphire Nitro+ model, while most of the Craigslist postings have been over $450 with a very few between $400 and $450 on ANYTHING Polaris).
I suspect that's due to this area having VERY CHEAP electric though - people are NOT shutting down rigs here - while your area has quite a bit higher electric pricing.

On ZEC, a 1080 ti will easily exceed 680 sol/s with good efficiency and can get to almost 800 on good-cooling cards if you push them, while 1070s struggle to beat 400 sols with good efficiency and you're VERY lucky to beat 450 sols/sec by much when pushed hard - the performance vs cost numbers USING YOU PRICE FIGURES work out pretty bloody close.

That's not true, 2x650w corsairs cost ~€90. The cooling isn't that bad either, the hottest cards I have are the single fan nitro 570's and they didn't go over 70C last summer after I installed some ghetto ass cardboard vent shafts.

Also most 1070's can reach 500 sols, not to mention they can do other algorithms like daggerhashimoto or neoscrypt much better relative to cost than a 1080ti.

The power cost is on the average ~€0.15/kWH here but anyone can get it down to 10 cents if they draw over 15MWH monthly or even a few cents lower if they are willing to move.
