I have a Radeon 4350 on a computer that is a few years old. Every time I try to mine litecoins it crashes.  I can mine terracoin and bitcoin ( not very quickly). I am not expecting to break the bank but before I put any money into it I wanted to prove I could get it running. Is it possible that my hardware is just too old to be compatible with scrypt mining?

Well, it IS old, but you should be able to mine anyway.
"It" — ???. Miner crashes, or card driver crashes, or your system crashes?

The miner crashes. Usually I get the windows message "the program has stopped responding" and it shuts down. It is only litecoin. I can mine bitcoin and terracoin just really slowly. I tried changing the intensity on cgminer with no luck. Reaper just crashes when I open it. If you can't tell I am very new to mining hahaha.

definitely too old

and too weak for mining

How much ram do you have, that can affect reaper... slowly probably is because your card is old, but I have a new Nvidia 650m that I'm using for tests before putting money into it (this is on a new laptop) and I can't mine litecoins either just bitcoins and terracoins.

I have 6 gigs of RAM. I know it is weak, but I also am just running a test before I sink any real money into this. Is there any way I can test out litecoin mining or am I just going to have to take a shot with a Radeon 7750 (Seems to have the lowest downside risk ie.  its cheap)

I have ati 4670, can i mining?

anything older than 58xx and you are wasting your time and money

Why is it a waste of money if you already have the card ?

In the real world, electricity costs money.

Old, but the reason of crashing maybe is from something else.

I tried to switch my 7950 card to litecoin mining - wasn't really worth it, really disappointing hashrates compared to the power consumption. I'm back to mining bitcoins for now, while that's still marginally profitable. Mining litecoins, I'm getting nearly the same hashrate using the spare CPU cycles of three rented root servers (i.e. I don't pay extra for electricity) that I was getting with my 7950.

You should be able to mine at a card of "any" age. It may not be profitable, but it should neither crash your machine.

Question is if it's worth spending the time to find out why your card crashes your machine.

Maybe your card is faulty if it keeps on crashing. Does it crash under stressful operation not related to mining (i.e. gaming or similar)?

The card doesn't crash just the mining programs. What card would you suggest then for mining litecoins? and make it profitable, even marginally so.
 

Only use ASIC for mining.

same would only recommend acis

Yup at the end of the day it is all about how efficient you are at converting energy into hashes. ASICs are most efficient.

Any new ATI card. My recommendation would be 7950's - they get you the most hash for your money and power consumption so imo they're very worth it.

I'm currently running a few of them and each gets 600KHash minimum on Scrypt coins (litecoin included). There are optimizations if you look around to get 7950's to 650ish KHash with lesser power consumption - imo definitely worth looking at.

uhh, no. As the difficulty increases those cards will not be worth using anymore.

FYI there are no asics or fpga's for Litecoin at the moment. A few FPGA's are being developed (check out the altcoin section) but they simply are not around at the moment, so everyone is running multi-gpu rigs.

What about a XFX GeForce 8600 GT Fatal1ty ? Could I still use that to mine Litecoins at an acceptable earnings to cost ratio? It's the fastest graphics card I have.

Alternatively what is the fastest graphics card I could buy for an AGP bus which I could use to mine Litecoins? Don't have the cash to upgrade the mobo/processor/ram but if I only have to buy a graphics card I might manage it.

Please check out http://dustcoin.com/mining - if you do some basic calculation, you'll find something like Litecoin mining to be plenty profitable at the moment. Sure, there is always the arguement that once the difficulty increases, it'll no longer be worth it - but do you really think thats the way its going to work? You dont think the market price of Litecoin will adjust to the difficulty of the coin? As scarcity increases, price will also increase. You're allowed to say anything you want and speculate anything you want, but mining simply wont be unprofitable until FPGA or ASIC farms come into play for scrypt, and that wont be for a long while.
