Cryptocoin Mining?

I'm making under $1 a day now with my MSI 7950 on LTC with the jump to 650 difficulty. BTC is about $0.80 a day. However two months in and i'm very close to having 2 BTC mined and in the UK I can sell my 7950 on ebay for £200 easy ($306). So i'm already on to a positive ROI and should hopefully...

Looks like the Yanks here are in the same situation as us Brits now? Nightmare trying to buy and sell BTC into local FIAT. Brit banks have been systematically shutting each new route getting money in/out of Mt.Gox Since March. Looks like you are the same as us now where the only route is...

Where will LTC price go in the near future? It needs to go up again as it's almost level now on priofit with BTC mining via GPU as it can't seem to break above 0.30 BTC. A month ago we where in the 0.20 -0.22 BTC range but pulling 2 LTC a day out on a single AMD 7950. Today we are at just...

Cryptocoin Mining?

Really? I switched a few days ago to Litecoinpool.org as I managed to get an account there after a 3 week wait. Give-me-ltc seems to be having constant server / ddos issues in may but then they are often up to 25% of the LTC network hashrate. M

I have mentioned before my 7950 rig is an adapted 2008 HTPC rig that is just for mining 24/7. You are right. desktop is barely useable at 625k/h. But I often go 48hrs without touching it at all. I have a seperate Q6600 + nvidia 560ti rig for gaming general use. One of the advantages of being...

Well Feathercoin mining lasted a whole day and a half for me! Woke up and the difficulty has shot up to 188 from 122 meaning in 13 coins a day now rather than 20 and the price has tanked form $0.45 to $0.20. More profitable to mine LTC again so back I go. Now what to do with my 30 FC? lol. M

As mentioned above, I found you need system memory to match GPU memory GB for GB. Also are you using catalyst 13.3 beta drivers or newer? I jumped at least 60-70 k/hash moving from 12.8 to 13.3 beta. M

Read my detailed post on setting up a 7950 with GUIminer scrypt on page 180 of this thread. 550 -630 k/h should be easily available for scrypt with the right settings, drivers and amount of system memory. However to get above 600k/h you probably need the "boost" edition higher spped 7950's...

You need more system memory. About 2-3GB per card, min of 4GB. I could not get my one 7950 over 400k/h on 2GB no matter what afterburner settings I tried. Upped it to 4 GB and bang............was able to use GUIminer default 7950 (High) settings tab straight off an 625-630 k/hash. Then it was...

Agreed. Three points. 1) 300m/h is nothing, for less than 3 BTC I have 5G/hash coming in the next few months from BFL. 2) With a GPU I can mine SH256 and scrypt cryptocoins. 3) I've been watching second hand prices on all 7950 cards on Ebay.co.uk for three weeks now. You can't buy one...

LOL. i assume Feathercoin is on the same SH256 as Bitcoin, hence ASICS killing it? What is the current difficulty compared to Bitcoin? Pretty much if any sh256 bitcoin gains value traction so pool owner will kill it with a 51% attack after selling all their stock to keep the value of BTC...

Hmm. How do you do that in GUIminer-scrypt Alpha? I have give-me-ltc, coinotron and now litecoinpool tabs all set up and working but can see to settings tab ot tickbox to activate automatic backup changeover it one pool stops working. Using CGminer backends with GUIminer BTW if it helps. M

My order number placed on the 22nd was 45300 something. However, my Invoice number paid there and then by Paypal is 21000 something. I think we should be more inclined to go via invoice numbers as they are only produced on payment. There could be 20000+ unpaid bogus "orders". M

Agreed. Hence my previous comments it it takes 2 years to get to market a litecoin FPGA with memory attached they could find that the top end AMD HD9000 series will have twice as many shaders as the HD7970 and use 30% less power and be cheaper than a Scrypt specific FPGA. In theory a single...

Doing better than ever though! LTC/BTC has droken 0.033 now today. The old peg of around 40LTC= 1 BTC has gone for now. And this is what is important to me rather than the $/LTC price as it's easier and cheaper to get LTC into BTC into FIAT than LTC into FIAT. Still, lovely to see LTC...

And will LTC FPGA Miners be able to out develop AMD ? Don't forget GPU companies have product cycles of 12-18 months, sometimes less. From what I read at first the HD8000 series will be tweaked HD7000 series so no more shaders. But lets say in later 2014 a new lower nm HD9000 series arrives...

AMD destroys Nvidia at Bitcoin mining, can the gap ever be bridged?

328 terahash by end of july? Not gonna happen. I doubt we will enven have this much network hashrate by the end of 2013. The whole hashing power of Avalons batch 2 and 3 which jhave not shipped yet are 1200 x 60g/hash. This is 72 Terahash. Enough to just about double the network hash rate now if...

True. I'm sure when BTC was $25 usd many said the difficulty and ASICs will kill it. But the price is now over $100, has already broken $200 once and could easily be $400 in 6 months. Then a x4 difficulty from now means nowt. M

Just checking the maths here. Batch 1 = 300 x 60,000 m/hash = 18,000,000 m/hash = 18 Terahash. I assume these are all with customers now mining. As stated Since feb BTC network hashrate has doubled from 33 T/hash to 65.73 Terrahash. So where has the other 14.73 Terrahash come from? More...

The AMD 7950 is the most effeicient. in a single card basic rig it can do 500m/hsh @ 200 watts. That's 2.5 m/hash a watt. With all this talk of ASIC's I beleive for the difficulty to double the network hashrate has to double? It has already doubled since February from 32.5 t/hash to 65.73...

You need to lower youe vcore voltage using MSI afterburner by forcing constant voltage------------afterburner---settings----force constant voltage. Try setting 1100mv first and if stable lower 10mv at a time until the card locks the drivers and auto recovers. Then go back up 10 and decrease...

In theory the $/BTC and $/LTC prices should rise to balance out the reduced production rate. $/BTC has risen from what, $15/BTC in January to $115 today. That's almost a 8 x increase in price for not a 8 x increase if difficulty / extraction rate! This is why since Avalon ASIC shipped...
