Miningchamp - Find hashrate of Graphics card

Scrypt-N, what is it?

OK, so I started mining Bitcoin with 336Mh/s USB ASICs back when they were $10/each. By the time January hit they were useless, although they still generate about $7/week.
Then I bought an overpriced R9 280x and have been making a decent return every week. Now I'm seeing hashing speeds drop and on /litecoinmining I see posts about how there are scrypt ASICs coming.
I was really disappointed to hear this as I thought (and have argued this with friends) that Scrypt coining has been generally safer because to get high hash rates we all have to buy the same type of hardware, video cards, which usually only do 1 or 2 generation bumps a year, and those bumps don't always come with huge performance increase.
I also saw a few comments about Scrypt-N coins (panda, quark, etc.) How do these hashing algorithms differ from Scrypt coins (litecoin, feathercoin, doge, etc.)? Are they truly safe from ASICs? Should I switch to mining Scrypt-N coins now, and if so, which coins would be recommended?
I don't want to switch to a coin that's just going to be a pump and dump as I don't believe they truly help the community.

AMD r9 280x hash rate

So I am pretty new to this alt/bitcoin mining thing, but am looking to get into it. I am probably going to buy a r9 280x to mine with. What are the hash rates I can expect with this card? It looks like 750ish GH/s is reasonable?
Thanks!

SHA256 with ASIC compared to Scrypt with GPU

this is the very basic for latecomer always doesn't understand.
i keep seeing they insist on mining bitcoin with SHA256 ASIC, i know its fun, its fun to see you generate money out of thin air, but thats not how we do it today because SHA256 ASIC era are gone, its very expensive playing field right now, if you insist want to mine some bitcoin, you should start mining using GPU! why?
lets calculate profitability of your SHA256 ASIC, and lets make it really easy by assuming some factor :
now go here you will see you will get 1 BTC in about 75 days right now (see the 2nd column from the rightmost), this value is not correct since it does not account for difficulty increase within 75 days, bitcoin difficulty are increasing about 35% in 2 weeks, thats about 70% per month, you will see the correct calculation is here which you will never get 1BTC within a year, and after 6 months your ASIC doesn't generate bitcoin anymore
now lets compare it to GPU miner for Scrypt mining, which i use realistic assumption here
now go here, you will see that on the most profitable coin (first row) you will get 1 bitcoin for about 30 days (its 45 days faster than SHA256 ASIC), how about difficulty increase within these period, this factor is not as scary as bitcoin, lets see difficulty chart for LTC here, you will see that the diff is up and down, by calculating the data history for 1 year, you will get that LTC difficulty increase is about 3% per month on average (this is 25x smaller than bitcoin difficulty change rate), so coinwarz data is not too much way off here by not take into account of difficulty increase
TL;DR;
note: this calculation are made in worst case scenario for GPU compared to best case scenario for bitcoin ASIC
thats just prediction and calculation, things will go wrong right? lets see the report from my own GPU mining rigs here, see 2nd sheet (RIG1-Report), this is my earning report day to day in BTC (already running since december 2013), my rigs cost about 2000$ (this is 2nd hand 6x AMD 7970 for 4.2MH/s) and will ROI within 50 days from start if my calculation are correct

48 hours at 750 kH/s, checked my balance... 0.00001301 BTC. Is WP broken? Or a scam? Or am I missing something?

I entered my receive address I'm mining with in here:
http://wafflepool.com/miners
and I get: Hash Rate: 0.00 kH/s Blocks Found: 0 (show last 10)
Bitcoins sent to you: 0.00000000 Bitcoins earned (not yet sent): 0.00000971 Bitcoins unconverted (approximate): 0.00000330
which totals a tiny 0.00001301 BTC (around half a US cent per day).
I made somewhere around two hundred times this much per day in January on 200 kH/s using Middlecoin.
I've switched back to middlecoin for now, of course, but I'm curious to know what's wrong?
Is wafflepool broken temporarily/permanently?
Or was it a scam from the start, shortchanging some miners?
Or am I just misunderstanding something, doing something wrong?
Any thoughts?
Using sgMiner 4.0.0 on R9 280X, averaging > 750 khs
Edit: Thanks everyone, looks like it was a configuration issue. There was a little "HW" counter at the top of the screen and it was going up every couple of seconds. In all the tutorials and readme.txts I've read on mining, HW errors were never mentioned. Trying to fix it now.

How to fix crashes and low hash rate on my new scrypt rig?

I need help to get past two major problems in my scrypt mining machine (see my config at bottom).

1 problem is system crashes during mining, even with low hash rate

2 problem is the low hash rates. 280x running at 400 k/hs and R9 290 at 180-400 k/hs

So far I have tried mining on Windows 8.1, Litecoin BAMT Linux and SMOS Linux with much luck. On Windows 8.1 I have gone through tons of AMD Driver versions from 13.1, 13.11 beta v9.4, 14.1 beta, 13-12, and bunch of other versions. Even tried couple of DDU clean ups. I have also tried different iners like cgminer, bfgminer, etc. Note on windows 8.1 I can't see GPU temp either. However, the hangs and low hash rates persist. One of the main issues is I can't get around play around with miner settings due crashes.
On linux at least I can see GPU temps. But from my testing the system still hangs when running at 400 k/hs on my two R9 280x or 180 k/hs on R9 290. My setting for above on cgminer was (2x 280x and 1x 290 at the end):
cgminer.exe --scrypt -I 12,12,12 -shaders 2048,2048,2560 --auto-fan --target-temp 65
Here is my hardware config:
MSI Z77A-GD65 Motherboard(highly recommended on bitcoin.org board)
Intel Celeron G1620
Corsair RM 850W
G.SKILL 8 GB (4GB x 2)
Sapphire Radeon R9 280x
MSI Gaming R9 280x
XFX R9 290x R9-290A-ENFC
Anyone got any suggestions on what to try next? Seems like very hard to mine effectively, for me atleast...

This dogecoin adventure is crazy...

Hey guys, I'm a new shibe but I've been watching this whole dogecoin thing since it came out and I want to tell about my adventure... I remember hearing about dogecoin when it first came out, and my first thought was basically "well this is kind of stupid that this is a thing now but what the hell I'll check it out." I was mining litecoin at the time on just a ATI 5830 which only gets like 275 kh/s for me, so dogecoin felt more fun when I started mining it at such a low difficulty.
Anyways, I traded chunks of doge into litecoin a little at a time but then like a week ago I was impatient and had accumulated like 140k doges when the exchange rate was about 43 satoshis, and since I was impatient and wanted to actually buy something, I traded ALL of them for litecoin, which I then added to my other litecoin stash on BTC-E and then switched the whole thing into bitcoin. Then I bought a R9 270x from bitcoin store and was all proud of myself because I bought a video card with only mined coins!
Now I'm sitting here looking at the exchange rate and my head is exploding. It's cool having that video card (hashing away mining more doge now) but when I see how much that doge I spent is worth now it's kind of bittersweet, especially with the huge difficulty increase. I could have got a 280x with only my mined doge at this point without having spent any of my other coins!
It doesn't bother me too much though because it's all part of the trip to the moon right? So yeah that's my story, and I'm definitely having more fun with dogecoin than I thought I would initially even with my occasional losses (I wasted a bunch gambling too early on lol). I'm also completely new to reddit by the way, so... sup guys?
