hi All....

just beginning to get into litecoin mining. wats the best way to have multiple PSUs on the rig? the shop advise in getting a molex splitter for the mobo. some sites says just jumpstart the psu...? any ideas?

huh!..... sad sad day~!

Hello friends,
MtGox is gone. So let's prepare ourselves.
On Tuesday, and for the rest of the week, all hell will break lose in the media. It will be blamed on MtGox, it will be blamed on Bitcoin, it will be blamed on the "bug," and it will, more than anything, be blamed on the "lack of regulation." Pundits and "experts" of all types will weigh in on the calamity. It will be world news in a matter of hours.
Get ready, because it will be an ugly week.
For all of you who lost money, my heart goes out to you. Some people lost a little, some lost a fortune. It will make people sick, and depressed, and full of grief. Personally, I had over 550 BTC in Gox. I will never get any of that back. If misery loves company, then we'll be enjoying a grand feast today.
I should have known better, of course. I take responsibility for leaving those funds with an entity that had proven incompetence repeatedly. I chose to ignore even my own warnings, for nothing more than the sake of convenience.
Gox is still at fault, to be sure, but I have learned the lesson. I hope it is not such an expensive lesson for others. And for all you observers, please take a moment to consider it as well.
Be mindful, however, that the wrong lessons are not learned, for that would be the true tragedy, indeed.
Let me suggest that the lesson is not that Bitcoin is broken. Bitcoin is fine.
Similarly, the lesson is not that security is impossible. Those who know what they are doing, can achieve it and help others to do so.
The lesson is not that nobody can be trusted. There are countless good men and women in this community who are worthy of trust, and some of the very best people I've ever met.
And finally, the lesson is not that we ought to seek out "regulation" to save us from the evils and incompetence of man. For the regulators are men too, and wield the very same evil and incompetence, only enshrined in an authority from which it can wreck amplified and far more insidious destruction. Let us not retreat from our rising platform only to cower back underneath the deranged machinations of Leviathan.
The proper lesson, if I may suggest, is this: We are building a new financial order, and those of us building it, investing in it, and growing it, will pay the price of bringing it to the world. This is the harsh truth. We are building the channels, the bridges, and the towers of tomorrow's finance, and we put ourselves at risk in doing so.
We are at risk from accidents. We are at risk from fraud, from corruption, and from evil. We are at risk from journalists seeking headlines and from politicians seeking power and glory. We are at risk from the very market we are trying to build - a market which cares not about our portfolio, our ambitions, or our delicate sympathies.
For all these risks, devastation will befall us repeatedly. Some of us will be discouraged. Some will be ridiculed and insulted. Some will be tricked, or swindled. Some of us will be crushed or caged. We will be set upon by all manner of antagonists, repeatedly, for a long time.
So why do we do it? Why do we build these towers that fall down upon us? Why do we toil and strain and risk our precious time, which is the only real wealth we possess?
Because the world needs what we're building. It needs it desperately. If that matters to you, as it does to me, then hold to that thought. You will see through the smoke, and your wounds will heal.
So shake it off, brothers, for this won't be the last calamity endured before the win.
Tonight, my heart is with you all.
Tomorrow, my head is down. My eyes are open. And I am building.
Toward peace and freedom,
-Erik Voorhees

Hi all.... Im starting some small rig for ltc mining. The power rating for r9 280x at full load is 477w ... 4x gpu adi 2000w... If psu can only provide 80% of the rated... How is that possible to have a single psu to power entire rig? .... If 2 psu means 2500w?...

Anyone can advice me?... Thx

mine is at 740 kh/s

tc - 8192

is there a difference?.... increase higher tc means wat?

ya sapphire r9 280x vapor-x

haihz... new problem

i got a
cooler master 500w psu 80+ silver
lga 775 core 2
4gb ram
usb- bamt 1.3

like cannot supply enough power.... i tot the card rated 250w + mobo (200w) = 450w
should be sufficient. it keep random reboot. then swap a 1250w ...run stable.

Hi folks.... after mining for a few hours, i keep getting intermittent GPU fault problem. got red screen on the BAMT 1.3

keep getting this errors: "A fault has been detected on GPU 0"
board is undervolted at 1.038v

Below are the settings for my board:

any ideas?

lower the gpu engine or gpu memclock?

sry i dunno wat the diff between the two...

gpu vddc at the config file is 1.200 ... dont need to change?

many thanks cloudstrife07 ...

yeah lowered the voltage using bios flash
ok ... i think will tweak the gpu engine,

spent yesterday nite looking at best config and lowering voltage for my gpu...

thanks cloudstrife07.

huhu..... learned new things today. tonite reflash back to 1.09v

ar188 ... curious, can u share with me ur config n volt since we both same cards?

Haish.... Still waiting for the dummy plugs to come all equipment i buy adi. Waiting for the plugs....

Nonit dummy plug.... Hmmm bamt says need. Dats wat the guide says la...

sapphire r9 280x vapor-x

wide n narrow got diff?... mine is narrow wor... powered riser.

cloudstrife07 ... are u able to order longer cable for the usb risers, just the usb cable alone (100cm) ...? i bought usb extension cable... seems like its not working..zzzzz

bah...~!

bamt 1.3 gives me 740 kH/s .... consume 270w gpu alone
bamt 1.5 gives me 550 kH/s .... consume 220w gpu alone

gpu volted at 1.15V

guess catalyst 14.1 run more efficient power?

bamt 1.3 - 13.11
bamt 1.5 - 14.1

im sticking to bamt 1.3... higher hashrate

is it normal to have GPU 1 with those figures?
looks like something sot.!

All boards volted at 1050v

wah! this tered moved here liao... i didnt notice.

new update.... been crunching for 3 days. twice kena GPU dead.
rebooted and lowered the GPU. I noticed always the 16x pcie kena ... dont understand. Also its the only port where the monitor can display.. someone tell me why?

im using 1x usb powered riser on the 16x slot.
my board - asrock h61 pro btc

i dropped the gpu to lower clock speed now, its hashing a little lower than the rest and lower temps... will continue to observe until tmr...

running 1.050v for 280x ... stable but averaging about 710kh/s

how exactly do i cash out from LTC to an maybank account?...
LTC - BTC - mbb?

best way for a msian?

yup ... im asking which exchange can use which is reliable


dats alot power .... u didnt change the voltage did u? with 4x 280x n mobo im running at 940w ..
