Yeah i am getting 398kh/s and no hw !! is 62 degrees normal?

wanna share with you guys. if want get high profit. sell BTC with paypal payment. I sold 1 BTC for RM 3100++. with that rate 1 BTC is more than USD 900 already. to be exact I got USD 940 with 1 BTC. Sold through localbitcoin find buyer that wanna use paypal to pay. paypal to cash is easy, just link your atm/debit card.  surprisingly the buyer is from UK and the trasaction was very fast. I quickly withdraw the paypal to local bank

the buyer most probably got paypal balance inside. pay directly to my paypal account. Since my paypal acc is already link to my maybank debit card (cherry atm card) I have no problem to withdraw the fund later on.
paypal to local bank takes 2-3 days.

I use localbitcoin website. find the buyer which wants the BTC payment through paypal. Once I received the paypal,  I release the bitcoin to the buyer

here are the steps. hope it helps

a) open localbitcoin acc. it has wallet feature

b) transfer all your earnings to this wallet. it takes as little 2-3 confirmations

c) find potential buyer, local or international that wants to use paypal. I was wondering why paypal rate always better than local bank transfer (local bank transfer MYR 1.9-2.2K/BTC. paypal can be as high as MYR 3.2k/BTC)

d) key in how many BTC you wanna sell. in my case I put 1 BTC. the buyer use MYR3k++/BTC rate.

e) by now, your wallet has been deducted by 1 BTC in their system but not yet release. system send message to the buyer you wanna sell 1 BTC for certain rate agreed or offered by the buyer.

f) you wait for thee payment. paypal is fast!

g) paypal received. you release the bitcoin to the buyer.

h) In my case i quickly withdraw paypal to my maybank account. this acc already link paypal<-maybank-> atm cherry card. wait 2-3 days for the money to be transferred.

i) you may use the paypal money for online transaction though (amazon/ebay/buy now/newegg etc)

anyone heard of world bitcoin conference at TS?

No idea bro.. Dont know whats there to see..

Just need to add PSUs + fans tomorrow

Yup, Ikea baset

Going soon to buy PSUs, woke up too late today 

The 1000W PSU is only connected to first 3 GPUs, other 2 are on a separate 860W Seasonic.

Total draw :

Rig 1  (5 x 280X) = 840W + 500W = 1340W
Rig 2 (3 x 280X) = 695W

Electricity costs RM0.5710/kWh = $0.173

Current Kh/s = 2326

http://www.coinwarz.com/calculators/vertco...9100000&hc=0.00

you measure with killawatt also? (that is wall power)

check your psu efficiency.

and also 660W includes total system power (MOBO CPU etc)+inefficiencies..

so adding per card is only 200-230w range

All my 280X are running undervolted at 1100, looking at others I might be able to decrease that a bit further, will have a try later and see what voltage I can achieve.

u know the funny thing, am using a cheaper CX750W bronze bought earlier, is also pulling 650W from the wall.. (also dual 280x) at 1.2V

dunno if that plat seasonic is really good or not. my 1KW seasonic also sitting inside box unused, since cheapo PSU doing the work competently.. 

disco lights GPU..

yeah ok kua.. i lazy to tweak.. around 1.1 also ok already as long as super stable..

I think the important factor is Kh/s / Watt (unless your electricity is free )

Yeah, rising quite quick - so is difficulty.

Got 17 so far 

By my calculation my mining so far will bring electric bill to RM1.3K, RM1.8K once all cards are running 

yeah look at my DCU2.. mine until gigi patah..
