[SOLVED] Mining On Radeon HD 4670

Recommended Posts

Hi

I know the HD 4670 is a very old card, has anyone managed to use it to mine mincoins ?

If so, could you please guide me how to, I have tried Cgminer, different versions, and even GUI miner scrypt Alpha, Bitcoin Mining works, but crypt won't run.

I have all the software required installed:

  • AMD Drivers
  • AMD APP SDK Runtime

 

 

 

SOLUTION: I got it to work by setting worksize to 64 ( -w 64)

The best things to do with a new card is to look around at various "mining hardware" charts and see if you can find the GPU listed. If you can find the exact model, you can often get pretty good starting tips for your own mining & tweaking.

 

One such chart:

https://litecoin.info/Mining_hardware_comparison

 

Unfortunately, your exact card isn't on that list, but as you see, others nearby have been used successfully.  I do realize that's a Litecoin mining site/chart, but MNC is also a scrypt algorithm-based coin (for now?), so when you find info on mining anything "scrypt" with your card, it will also apply to MinCoin.

 

These charts tend to list things like overclocking and such, but for starters, just use very basic commands to get the mining software running and then tweak from there (by adding commands, etc.)

 

For instance, I'd guess this /should/ work for starters by using the guide and command line for CGMiner listed in Vipah's pool under Getting Started:

http://mnc.vircurpool.com/index.php?page=gettingstarted

 

If you continue to have troubles, you'll need to post more details about error messages, etc. that you're seeing.

 

Good luck!

What would people recommend for a card for mining the coins?

One of the best GPU chips for mining right now is the AMD Radeon HD-7950.  It's still quite popular due to its good hashing power potential, along with it using less electricity/heat to operate than the higher-end chips like the 7970.  New GPUs will be coming out soon (I'm not keeping up with current announcements, to be honest)... always something new coming soon.

 

Definitely stay away from any Nvidia chip-based cards though.  They don't work anywhere /near/ as well as the Radeons.

 

There are a lot of charts that show hashing rates and settings. so read up on a card you're thinking about to see how it stacks up, if mining is going to be a big part of its use.

I have AMD APP Installed, but it tells me. no Open Cl Devices Found

You've installed GUIminer scrypt and have all of the proper drivers. Is it returning an error message when you try to connect to a pool and mine?

 

Is cgminer recognizing your device? Can you run games on your computer via the device?

Typically, that sort of error has popped up for me if the AMD drivers aren't installed properly or some such.  The most recent drivers don't need anything extra to be installed like prior versions did. You used to need to install the SDK separately, but relevant mining stuff got rolled in a while back.

 

Also, what operating system are you using?

Agreed about the HD7950 being the best for now.

 

I bought HD7970's and regretted it, I pay 24c per k/w and I was barely breaking even with their huge wattage draw.

 

Had to stop now that summers coming back, hard enough to keep the house cool when its 40 + degrees outside.

Is the gigabyte a 6950? err?   I have a gigabyte 6950 and no luck on flashing the bios..

 

How much are you selling for though?  and which model?

I have windows 7 installed, and drivers version 11.10

 

The driver versions for all their software often is confusing. There's the Catalyst version, the display driver version, OpenCL version, etc.  It's a rat's nest.  If you're talking about Catalyst 11.10, you're not on current drivers.  It looks like Catalyst 13.9 came out a few days ago that supports the HD 4000 series:

 

http://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows%207%20-%2032

(32-bit windows link, if it works)

 

Maybe give that a shot, unless I'm understanding wrong.

 

Also, as another shot in the dark, maybe try mining with their stratum connection and see if that works? I'm not familiar with Slush, but I saw on their site that you can do stratum.  Instead of your -o URL, give this a shot?:

 

-o stratum.bitcoin.cz:3333

 

There's some chance that you might need protocol also, but that was pulled from their page.  If you need more, try this:

 

 

 

Let's see if any of this helps. :)

Ugh.. I realized I'm doing too many things at once and they're getting munged together... you were telling me that while mining BTC at Slush, it works, but when you try --scrypt, it doesn't.  Also, we're not talking about Slush's pool, but that was just your example of non-scrypt.

 

*sips more coffee*

 

OK... sheesh...

 

If the drivers info I posted doesn't help, please post your full cgminer command line string here, or go follow a guide like on here:

http://mnc.vircurpool.com/index.php?page=gettingstarted or similar

 

I'm groggy and distracted with too many projects.. sorry if I'm just making noise instead of helping. :P

SOLUTION: Got it to work, I set worksize to 64 ( -w 64)

Sorry I missed helping out.. I was out of my office for a long weekend.

 

I've noticed a lot of issues with changing the worksize for other situations, but not yet with MNC.  Glad you sorted this out! I'll also add that to my bag of tricks to see if it helps others.

 

Thanks very much for reporting your solution, too!

I crashed my PC so many times when first trying to scrypt mine.  The thread concurrency setting would crash it everytime if it was set too high.  Scrypt mining is much more difficult than SHA-256, in the end though it is worth the effort.

Guys, I live in an all bills paid place. I pay a flat fee for my place so i get FREE Electricity. What type of graphic card should i get?

 

AMD chips are still the best for mining, even though people are trying to figure out Nvidia.  I would still say the AMD Radeon 7950 is a great chip considering cost & performance, as well as heat and electricity efficiencies.

 

I suppose I've not been looking for maybe a month or two, so maybe there's some hotness out or just about out, but those will be expensive if they're bleeding edge.  The 7970 runs hotter, uses more electricity and isn't much of a hashrate boost over the 7950's, but there will inevitably be something to take its place.

 

I suppose I better do some more rounds of research to see if anything's taking over my beloved 7950's. :)
