Mining Bitcoins in ESXi using an XFX 7970 zSprawl's zApps

Bitcoin mining OK, Litecoin not so much... System Freeze's

I'm not sure how much detail to include here, so here goes:
GPU: Dual 7970
Drivers: 13.1 & 2.8 APP SDK
OS: Windows 7 64 bit
I pull 1.3 Mhz easily. No OC. I'm not at home right now, so I can't pull my cgminer options (thread concurrency, shaders, etc) but I took them directly from the mining comparison website.
My temps stay around 68-72 C I use powered risers.
Problem: After starting mining I can run for 1 - 4 hours before my system will freeze. It's an incremental freeze, within a few seconds the main window locks up, seconds later I cannot change windows, then the mouse will lock up.
Then that's it. No crash, no BSOD. It just hangs. I watched my pool's site to see if it was just brain dead but still running, no dice my hash rate drops to zero.
The only way out is a hard reboot (power button).
When I mine bitcoin I don't have this experience. I understand, oranges and apples. After some digging I'm leaning on this being a mem timing issue.
Does anyone have this experience?
Edit: Cgminer settings:
--scrypt -o stratum+blah -u uname -p pass --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256
Edit #2:
I'm going to toss a bounty to the best answer

[XFX 7970s] 1.345 MHash/sec, ~35C, ~450 Watts

Resurrected my old Bitcoin rig for some dedicated LTC mining, FINALLY got it running stable after some serious procrastination studying for finals -__-
Evidence!: http://imgur.com/a/K3nYt
GPUs: 2x XFX Radeon HD 7970 GHz Edition (FX797GTDFC) flashed with this Gigabyte BIOS - http://www.techpowerup.com/vgabios/127156/gigabytehd7970-3072-120905.html
cgminer config: http://pastebin.com/raw.php?i=s072rzFF
Don't listen to anyone who says XFX GPUs are junk; maybe their firmware is, I won't argue that... but using the Gigabyte BIOS above I was able raise my hash rate to ~700 on each card @ 1000/1375 using around 450 watts, vs. ~550 on each card @ 1200/1500 using around 650 watts on the stock firmware!

Informative post about Feathercoin

Seeing how this Subreddit is lacking any sort of info on Feathercoins and the lack of community support we have, I have decided to start a post that would inform newbies about Feathercoin and seasoned vets on the best places to trade.
Feathercoin:
It is a Crypto Currency that was started by Peter Bushnell. It is a clone of Litecoin (This coin was inspired by Bitcoin). The Feathercoin network generates coins at a decreasing rate. It will generate about 336 million coins which is 16 times more than that of Bitcoin and 4 times more than that of Litecoin. Currently about 25 million coins have been generated.
Network hashrates, Pools, Solo mining:
Currently a mid end system comprising of 7870 or 7970 will get you abot 400 to 700 kh/s. That means that in a given day you will be mining about 7 to 13 Feathercoins on current difficulty level. However If you mine alone that is solo mining, the probability of you finding a block is hard and it may take a while before you make a coin. To counter this people have started making pools to increase the chances of finding blocks. There are many pools that allow you to have multiple workers so you can setup multiple systems and mine at your leisure. Currently some of the popular pools are:
http://www.fcpool.com/
http://give-me-coins.com/
http://www.wemineftc.com/
http://fc.ltcoin.net/
https://ftc.d2.cc/
For a full list of mining pools: http://coinpools.sdfg.org/ftc
It is highly recommended to join a pool to make mining profitable. Look at the pools posted above, look at their fee structure, their payout and make an informed decision on which pool to join.
Hardware and Mining:
Feathercoin utilizes scrypt based mining that is you can use your GPU (the Graphics card inside your system) to mine them. AMD Cards are highly recommended as they output higher hashrates as compared to Nvidia. To give you an idea of the difference a 7870 ghz edition mines at about 375 kh/s whereas a Nvidia 780ti would mine at about 224 to 300 kh/s. If you are seriously considering in investing in this venture it would be best to buy a rig that supports 6 GPU's and buy either the 7950 or the 280x as they have considerably higher hash rates and are affordable to say the least. Something one should be aware of is that mining produces a lot of heat as your system is basically running at full capacity and therefore needs a lot of cooling. People usually build rigs in the open (no case) and use household fans to cool them. Also another thing that is common is to use PCIe risers as they allow greater spacing between GPU cards and effectively help in dissipating heat. Mining uses a lot of electricity so it is best to use a schedule to mine or if electricity is cheap then 6 7950's running 24 hours a day would cost you about 12 to 18 dollars in electricity a month, maybe more depending on where you live. The software to use for mining are Cgminer (https://litecointalk.org/index.php?topic=6925.0), guiminer scrypt (http://forum.feathercoin.com/index.php?topic=961.0) and cudaminer for Nvidia cards. I would advise against Cpu mining as that is not profitable and will simply weigh you down. Invest 250 to 350 dollars in a good AMD GPU and you will be mining much more effectively.
Trading:
There are many places where one can trade Feathercoins but only a few of them offer FTC/USD exchange. Btc-e (https://btc-e.com/exchange/ftc_btc). Is one of the biggest cryptocoin trading exchanges, it does not offer USD exchange for Feathercoins as of yet but allows you to exchange for Bitcoins. Crypto-trade (https://www.crypto-trade.com/trade/ftc_btc), this trading exchange allows you to trade against the USD making it more favourable to miners however there is currently a lack of volume for FTC as of writing. Other exchanges like Cryptsy, Bter and coins-e are all good but they are heavily dependent on Bitcoins and Litecoins for now.
My thoughts
Feathercoin is fairly new and its gaining momentum, once big exchanges start listing it against the USD, the venture will become more profitable. For now it is advisable to mine as many as you can and sit on them till value improves or if you have a mining rig that is mining at 22000 kh/s (this will get you about 500 feathercoins a day) then mine the shit out of them and trade them for Btc for profit although I would recommend against this as it it reduces the value of feathercoin. Many exchanges allow you to deposit money via international wire transfers however the minimum is 2000 dollars so keep that in mind before investing real money into this venture. There are alternatives like paypal and okpay that are also accepted but not a lot of people have accounts on those so signup for a website that suits your situation.
One last ting we all need to do is spread awareness about Feathercoin, It is a miners coin and the difficulty right now makes it so much more interesting to mine. I will update this page with more information and will answer questions if any to the best of my knowledge. Happy mining

EDIT : I realized some of you might have NVIDIA GPU's and are hesitant on getting AMD. Never fear for there is a solution. If you have a motherboard that supports two or more GPU's that is you have more than one PCIe slots than follow these instructions:
If you intend to game on your system while you are mining then put the NVIDIA card in PCI slot one and buy an AMD card and put it in slot 2. Now install the drivers in the order Nvidia first reboot and then Amd second reboot. You do not need to plug in HDMI to your AMD card just leave it as it is. Now download gpu miner scrypt and select from the list your AMD card and start mining, its that easy. At night if you want to squeeze in more kh/s then run cudaminer and let it mine alongside your AMD. The best part about this is that you can be mining 24/7 on your AMD card and you will not experience any system slow down while gaming or watching movies. Remember to have atleast two workers workers created so you can mine parallel. If you already have an NVIDIA card then just install your AMD card and install AMD drivers and reboot and run guiminer scrypt. At times you might run into the issue of guiminer not starting, just delete it and re install it and it should work fine in 98% of the cases. This is for those who do not want to invest in a completely new system and would rather use their existing system. You can use cgminer as well but remember the order in cgminer starts from 0 not 1 so if NVIDIA is in slot 1 then it is -d0 -g0 and AMD will be -d1 -g1

New to mining litecoin I need some help please.

Hi,
I had been mining bitcoin as a hobby while block erupters were still profitable. Now I have an interest in litecoin I have seen a lot of posts about people optimizing their mining and cgminer in general. I have been using Guiminer scrypt and I feel like I am not squeezing as much performance as I could. I have no idea how to set up cgminer and it confuses me even more when I have to setup different model cards in a single rig. If you guys could help me out get the best performance it would be greatly appreciated.
What I currently own and the hash they are creating:
which is a total of 3.95mhs
In the pool I joined it seems that it translates to 1.2LTC estimated earnings per round.
[UPDATE] Separated by rigs
Thanks in advance.

Cannot get over 450kH/s with my 7970..please help

I'm able to hit 730Mh/s bitcoin mining with my Asus Matrix Platinum [email protected] 1250mhz core/1725mhz memory...but for some reason i cannot get over 450kH/s reliably litecoin mining.
Using the configs they use in https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison
Using either CGMiner or GUIMiner - none of the 7970 configs are very good for me
The highest stable memory i can get is 1725mhz...so using 0.57 rule, ive tried a core speed 984mhz..still doesnt help too much. Anyone have other configs i can try? I'm using give-me-ltc.com as my pool.
EDIT: Also using the newest 13.3 Beta drivers...i wonder if this has something to do with it..or maybe i should change pools..
These are the flags im using:
cgminer --scrypt -u jerrolds.worker1 -p x -o stratum+tcp://stratum.give-me-ltc.com:3333 --shaders 2048 --worksize 256 --intensity 13 --thread-concurrency 8192

7970 mining at a good speed, but i'm not seeing alot of accepted shares

I moved all of my bitcoin miners over to litecoin when my bfl rigs came in. The 7970 is mining at just under 700, but i'm not seeing a lot of accepted shares. This is what I see
I'm using these flags: cgminer --scrypt -o http://p2pool.org:9327 -u xxx -p xxx -I 13 -g 2 -w 256 --thread-concurrency 8192 --gpu-powertune 20
Is this normal? Coming from btc i'm used to seeing a long pour of accepted shares with a splash of work update requests.
Side question: I used to be able to force a framerate on the gpu when mining btc, can I do that with cgminer? I can't even use my mining rig unless i'm RDP'd into it and use the rdp vid drivers.
EDIT: p2pool was my problem, i switched to hashfaster and am doing much better.

CGMINER download/ settings for a 7970?

Hey all! Can anyone shoot me a viable link to download cgminer? Also! When I bitcoin mine I can OC my card for greater efficiency. With litecoin mining it doesnt seem to matter what OC settings I use. Anyone OC their 7970 with GUIminer -- scrypt?

Need help tweaking 7970s - stuck at 500-550 kh/s

I finally stopped being lazy and booted up my old 7970s that I used to mine Bitcoins. I am mining Tagcoins right now and I believe it will be up there along with LTC and BTC. It's only about a month old and is already at $1.7 and it's backed up by a multimillion dollar company. Read more here:
https://bitcointalk.org/index.php?topic=317408.0
Anyway a little history about these 7970s:
They were never overclocked.
They were always undervolted to 950 mv and memory underclocked to 100mhz
The temps were always below 70C with huge box fan blowing at them.
Current Settings for Scrypt Mining: undervolted to 1000 mv and stock settings for clock / mem at 925 mhz / 1375 mhz. These are Asus Reference cards (bought them at launch to mine BTC).
CGMiner Settings:
cd cgminer C:\Users\Bitcoin\Desktop\cgminer-3.7.2-windows\cgminer.exe --scrypt -o stratum+tcp://tagmining.com:3333 -u xxx.xxx-p password -o stratum+tcp://wk5.botpool.net:5933 -u xxx.xxx-p password -I 13 -g 2 -w 256 --thread-concurrency 8192 --shaders 2048 --temp-overheat 80 --gpu-engine 925 --gpu-memclock 1375
I am using the following drivers:
13.11 Beta Catalyst Drivers
2.9 SDK
CGMiner 3.7.2 (latest to support scrypt mining)
Computer Specs: i7 2600k 3.4Ghz Stock MSI Big Bang Marshall 3 8GB DDR3 RAM ASUS 7970 X 4 Reference Cards 1300W CoolerMaster Gold PSU 2TB HDD 7200RPM
Any help would be appreciated!

Some questions I have about mining

I intend to mine a bit on my gaming rig (my only computer, and I cant afford anything else). Not serious but maybe squeeze 10 bucks a week or something.
Q1: What config do I use?
I have a Sapphire vapor X 7970 Ghz model 11197-12-40G and I get about 400kh. I read that is way too little for my GPU, i use thing config.
set GPU_MAX_ALLOC_PERCENT=100 set GPU_USE_SYNC_OBJECTS=1 cgminer --scrypt -I 13 -g 2 -w 256 --thread-concurrency 8192 -o stratum+tcp://pickaxe.pool.pm:3301 -u coldblade2000.coldblade2000 -p die0600g del *.bin 
Q2: How do I make sure I get a good enough amount of bitcoins without killing my poor GPU?
I really cant afford another GPU, and this is my main and only computer. If it breaks, I'm SOL and left without a computer for months. How do I make sure I never kill my GPU?
Q3: What intensity/settings do I use to run thought the night safely?
Since I can use the night as time to mine without interrupting my computer usage, I thought I might as well, but I think my current settings are way too stressing for that. What do I change?
Q4: Is my pool ok?
I have been using doge.pool.pw and I just got my first payout, 288 doge. Not as much as I hoped but I don't see any other choice. Should I change pool? To which? I tried p2p pools but I found their interface annoying.
Q5: Is it worth it?
I don't intend to do this full time, or to become rich. I might just use 10 bucks a week or months, and keep the rest for when (if) doge goes up in value by a lot. Is this really worth the hassle, electricity bill and danger?
