It's a start for scrypt asic.
That Gridseed chip is made from 55nm process, IINM if the sale is good they'll probably proceed with 40nm which will increase the hashing speed by a lot.

Once scrypt asic overtakes GPU, time to find new coin liao, one that cannot be mined using this asics...

First gen scrypt asic is so expensive, if got so much BTC better buy SHA256 asics instead haha

from now to mid this year (before 2-3 others come out with newer/cheaper design).. go mine kau kau with GPU first lor.. get back capital or cost of equipment.. then it's only electricity.. and heat problem..
after that with some capital /BTC at hand, can always invest in gen 2 scrypt hardware.. which probably half the price and double the hashing power.

ic. thx for the info. im still thinking whether want to spend on 200 Gh miner or use that money to buy rig for litecoin mining.

hye rasa nak start bitcoin mining jugak. ada tutorial on how to start and what kind of rig should i get for mining ?

hi guys,
so i finally made a decision. i will invest on ASIC miner first. im thinking of buying Avalon 200GH ASIC miner from a person named sound_freakz. is he ok? or do u guys have other source ?

Play with the simulator.

do u mean the avalon 200gh miner?
please dont,the noise is not acceptable at all.
unless u dont care the noise.

in 19 hours from this post the difficulty will readjust again to 2,646,774,661

That's hella high difficulty

Buying back my coins on the weak of the 24th. The drop wasn't as dramatic as I expected.

probably because the market is quite distributed nowadays compared to last 4 months?

difficulty damn high.. mining with nvidia 630m at 25mh/s can get around 80 shares in 6 hours. few months ago I easily can get 150 shares in 3 hours. LTC mining just wasting electricity. need at least 2mh/s baru puas hati..

anyone want to buy bitcoin from me???

nah, nvidia gpus just aren't good for mining. It's awesome to mine if using Radeons. My previous HD7870 got 400kh/s, now using R9 290 i got 870kh/s

What power supply you use for R9 290 to get 870 kh/s?

Some miners claim to be able to hash at over 950 kh/s. Sound pretty impossible to me.

i think it's pretty normal to get 870khs. no?

can push 900+, but u need those uber boards la like Asus Maximus or Gigabyte Sniper, which in turn, not worth the price/performance ratio.

i think u got the wrong concept here.

bitcoin's mh/s = litecoin's kh/s.

so 2mh/s in litecoin is equivalent to 2gh/s in bitcoin.

current difficulty :2,621,404,453

OMG OMG OMG

I'm only running one R9 290, using Cooler Master Extreme 2 625w. Although not really a good PSU, it can run the system fine but I don't dare to overclock. On stock OC the card comes with 1000 core 1300 mem, I got 830kh/s like that, I run at 1000 core 1350 mem and I got 870kh/s. Maybe I got unlucky the card couldn't run fine with 1500 mem, some other users managed to get it run on 1650 mem...

Though I saw screenshots of people running at 980kh/s, that's the max I ever saw coming from single GPU.

third party cooling solutions really work wonders with the R9 290, temps are cool enough to have the card running without throttle.

what model of R290 u running ?

mind to paste the cgminer config here ?

my working config something like this
-I 20 -w 512 -lookup-gap 2 -g 1 --gpu-fan 70 --gpu-powertune 20

some of the high hash rates.. due to the fact they are running in the winter cold air..
