I did. didn’t help. currently I am using a single GPU with 750 W PSU, it should be more than enough

I even used the default clocks with 13 intensity. and I don’t see a crash, it keeps running and suddenly drops 200 . The exact same card is working perfectly on other rigs with the exact same clocks,

Hi Everybody.
I have been facing a strange problem. This is the 4th rig that I am putting together, the other 3 were working well without any problem, but this last one is causing me a weird problem.
the hashrate drops after couple of minutes of mining, GPU activity also goes to 65%. The hardware that I am using is similar to the previous rigs, nothing is changed. I am using sapphire r9 280x vapor.
this is my config file":

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -I 13 -g 2 -w 256 --thread-concurrency 11200 --gpu-engine 1080 --gpu-memclock 1500

with these settings I am gettign 750 Kh/s per GPU for my other rigs, but this last one goes as high as 650 KH/s then it drops to 540 KH/s, the GPU activity drops also to 64%. I tried changing the motherboard, changing the GPU, the RAM, CPU, Powersupply and harddrive. it didn’t help.
any idea why ?

50 FTC bounty for whoever can solve the problem.

Huge?

Compared to some of the other coins out there I would say ftc has far from huge numbers.

Well I am comparing to the two major coins, BTC and LTC.

I am a new FTC miner. I like it so much.
we all know feathercoins will be 16 times more than bitcoin and 4 times more than litecoins. We currently have around 25 million of FTC out there. I have a question from the developers of FTC and the community , Cryptos are merely based on the supply and demand. Don’t you think this huge number of supply reduces the price dramatically ?

mining profitability goes back and forth all the time . i was thinking that if or when the market gets flooded with fpga-asic scrypt miners , a lot of the dedicated litecoin gpu miners with switch to feathercoin . that will drive ftc difficulty up for sure. I think that’s plaussible enough . Difficulty does not always go hand in hand with fiat exchange rates but it collerates with the value of the coin nontheless

That’s what I always say to other people. Higher difficulty means lower supply which means higher price in turn.

Can someone please explain what cold storage mean and how I can do it. I have some confusions.
I have all of my FTCs on my laptop.
1.What exactly backup wallet does ?
2.if I backup my wallet and copy the backup file on a flash memory, will my wallet become empty ?
3.if someone steal my backup file , and load it to his wallet, my wallet becomes empty ?
4. In general how can I secure my wallet on a flash memory and put it on my safe ?
5. How can I transfer my wallet from one computer to other ?

Hi everyone,
I am a new FTC miner from Los Angeles.
Really like it and I am glad to be here.
Hope to push ftc to the moon.
