Is this a Good Hardware for Scrypt Mining?

[PabiGamito]

Hello,
I am thinking about buying a mining rig to mine any scrypt coins using the clevermining pool for best profitability.

Here is what I am thinking to buy:
CPU - Intel Pentium G3220 (3 GHz)
Memory - Crucial Ballistix Sport 4 Go DDR3 1600 Mhz CL9
Motherboard - Gigabyte GA-Z87X-UD3H
GPU - x3 Sapphire Radeon R9 280X Vapor-X 3G GDDR5
Case - NZXT H440
Power Supply - Corsair AX1200i 80PLUS Platinum (Not too sure)
Harddrive - Still not too sure (something cheap without too much space... <100GB)

I would like to know you opinion on this. Have anyone of you used this GPU for mining? And if so, what was you hash rate? I would also like to know if you think this will be very noisy. And if so, how can I make it less noisy? Also I am not too sure on the power supply as I don't have a too good estimate of how many Watts this will be using.

Please give me any suggestions or tips. I am brand new to this.
Thank you very much.

Why go with a power hungry,noisey,heat producing GPU rig

You can get a bunch of Gridseeds for that kind of money & use ALOT less power,360 mh/s=7 watts !!

Plus they are way easier to setup on an existing PC with these 6pin PCIE power cables from Cablez:

The only thing Gridseeds can't do is N-scrypt...I think,unless someone made a miner for them to do that too............

You will still need a large HDD,to keep around 5-10 or more wallets for all the altcoins,about 10-20 gig per wallet

If you want 280x that are not noisy you will have to go for ASUS cards, or even better. Go for 290 with reference boards and put an accelero extreme IV on them, that is the definition of silence. Only thing better is water cooling, but is really expensive.

If you're using a case then more than 2 GPU's is out of the question, they will get way too hot.

@Unacceptable makes 2 good points about Gridseed ASICs - they are much more power efficient than GPUs which keeps your running costs down, but you are limited to Scrypt based coins. The latter may become more of an issue when KNCminer actually start shipping their Titan Scrypt ASICs (apparently expected Aug-Sept now), I expect a lot of altcoins will move to alternative algos just leaving the more established ones like LTC & DOGE. Which wont be a massive problem, LTC mining will likely still be a much better ROI than BTC, but already the multipools which offer the best returns are those which focus on the "alternative" altcoins.

This post from Suchmoon https://bitcointalk.org/index.php?topic=514242.0 is well worth viewing to give you an idea of how the returns compare (and fluctuate). Personally I have a R9 270X and two Gridseeds running, which should have paid for themselves by the start of July, but rather than purchase more hardware myself I invested the btc at Scrypt.cc - after a couple of weeks trying them out I'm convinced enough to put their referral link in my signature.

If I am not mistaking, the way scrypt.cc works is that you invest Bitcoins into their mining system and they will start mining for you and then you will get a profit back. I just want to check if that is the way it works. And also as you have been investing into Scrypt.cc, could you tell me what you think about it and if the return is really what they say on their home page.

Thank you.

EDITED: Aslo, does the KnCMiner Titan actually mine at 300Mh/s or 300 000kh/s? And will it? Because it seems to be really cheap to be mining at that speed... If my calculations are correct, if you would be mining Dogecoins with the Titan, you would be mining about 60736 dogecoins every hour or about 30$... Witch would mean, about $20,600 a month if it is on 20/7...

Yes, with Scrypt.cc you buy KHS on their trading page which will then generate mining income for you until you decide to sell them. The mining income is paid to your account every 10min and is calculated from their mining pool's income minus 8% maintenance fee. Scrypt.cc operate their own closed mining pools so we dont know what altcoins they are mining at any time, but they appear to consistently achieve a profitability level comparable to the top mining pools.

Bear in mind that the return calculator on their homepage is only based on their profitability at the time, which can change a lot from day to day recently - on 21/04 it was around 0.1 BTC/MH/day, today its more like 0.05, but its been the same for the big multipools too. You really need to look at it as a longer term investment and see how the figures average out over a few weeks.

Personally my impression of Scrypt.cc so far has been good, they appear to be honestly trying to build a good service and I'd suggest you try it out. All altcoin related markets are risky though, I'm sure you're not planning on investing your life savings but I feel I should still repeat the warning to only put in what you can afford to lose A Gridseed ASIC is currently about 0.3btc, which will buy you 300KHS on Scrypt.cc, so maybe that's a good amount to start with.


And yes, KNCminer say that their Titan will be at least 300MH/s, which is 300,000 KH/s, which sounds like amazing value compared to current options (30KH/s per $, a Gridseed 5chip is 2KH/s per $). However bear in mind that you wouldnt be the only person to have one The difficulty factor ensures that the number of each coin mined per hour remains the same, what you mine depends on what % of the total coin hashpower you own. To estimate your returns when you get a Titan you need to take a guess at how many other Titans will also be mining that coin

GRidseeds are better option right now. If knc miner comes out gpu mining will not be profitable.

vapor-x tri-x are vastly better,  tamb 20 max temp 68 with scrypt with 1.2vcore

gridseed are trash don't buy them, you won't make roi and titan is incoming, they talking about delivering around june

gpu are ok just use them only for instamine, there is no alternative option for now, when the "craze" will return will all the new algo, point your rig at them and you should make roi more easily than now for sure

The Vapor-X's are good GPU's and just as good as a Toxic nearly, but gpu mining is very minimal profit at the moment. Only thing that keeps them profitable is gpu mining XPM. You are better off spending your cash on a Gridseed blade, better $/hash than Gridseed 5 chip miners.

But I have heard that there have been problem with the Gridseed blade. Errors because of over heating. Or should I not worry too much about that? Also, do you expect the Griseed blade to still be profitable when Kncminer's Titan comes out...

[flippo]

IMHO no. And you will not be able to use them for mining other algorithms, like you will be able to do with GPU's. If you by any chance have free electricity, GPU's are better.
