1  Other / CPU/GPU Bitcoin mining hardware / Is USB riser safe? on: March 05, 2014, 12:33:02 PM
I see people selling USB riser using the 3 pin- SATA connection to deliver 75W that normally run though molex. I know normal manufacturer have molex-6/8pin PCI-e convertor so molex is safe to use but SATA is for HDD which normally use 3W-5W. Is that safe to run on the long term? will the SATA power delivery enough wattage, or wont overheat/ melt

3  Alternate cryptocurrencies / Altcoin Discussion / weird "e e e" sound when mining with scrypt-jane on: December 30, 2013, 04:13:39 PM
I was trying to mine qqcoin today and noticed a very weird "e" sound from the card whenever i run the gpuminer. It sounds like coil whine but much more subtle. I would it is about 1/3 as loud as a coil whine. I have never encounter such thing with normal scrypt.

 
4  Other / CPU/GPU Bitcoin mining hardware / Crossfire Mining? on: October 31, 2013, 02:02:15 AM
I am a softcore part time miner, so I am  thinking to buy another GPU for both game and mining.
Is it possible to crossfire them to play offline game, then un-crossfire without having to unplug the xfire bridge and restart. So i can use 1 card for playing MMORPG while the other can keep mining?  I remember people mention that for crossfire both card will run on the same clock speed. After  un-crossfire can i run them on different clock/mem speed and voltage?

Press enter to continue:

I got this when i tried to run cgminer with my onboard graphic as display.

Also how can i change core, mem speed, core voltage, fan speed? afterburner, trixx dont detect my card. It tried --gpu-fan 50 --gpu-engine 1060 --gpu-memclock 1500 but there is no change in my hash or the gpu fan doesnt sound louder indicating the change in fan speed.

7  Alternate cryptocurrencies / Altcoin Discussion / Would fast retarget make a coin harder to pump-and-dump? on: June 19, 2013, 02:31:30 PM
Pump and dump make a  coin ran out of hashrate when the diff was too high compare to the price. However with coin that has fast retarget like Florin Coin would that make it less likely get pnd? After the horde leave, diff will go down very fast and make mining profitable again.

After investigating the security breach we have to come to the conclusion that the attacker has been able to get root access to the systems.

Therefore we need to assume that the wallets might have been copied, thus DO NOT deposit funds. Everyone will be getting a new set of addresses.

18  Other / Beginners & Help / Using GPU to mining and still use the pc like normal with onboard vga on: April 11, 2013, 10:06:11 AM
Hi, i am mining ltc now with my pc. I notice that mining only use GPU so i am looking for away to run cgminer with my 7970 while still able to use my pc normally utilising onboard vga (for video and internet).

I went to bios setting, choose main display as onboard vga. I was able to go into windows successful. However, MSI afterburn doesnt work. It only display 1 GPU - 7970 but no onboard vga, and i cant change voltage, core/mem clock, fan even though GPU-Z detected both.

Also, how can i config the .bat file for the cgminer?  I used GUIminer and it seem to work fine, 450 khash at stock speed (1070/1400 core/mem).

Hi, i just make a new account so i cant post in this thread. But can anyone help me post my question?

https://bitcointalk.org/index.php?topic=165397.0
It is a thread about Mincoin

i wanted to ask if the files linked by the threadstarter contain virus.
I am asking this because i downloaded the file. After that i use cgminer and despite of the miner say my speed is 650kh/s the speed status on litecoinpool website show only 18kh/s. I waited 30min to see the ltc amount and indeed i only have 0,023 instead of 0,5 ltc.

I switched to GUIminer but it seems to work fine, the pool site recognise my speed. I have the correct amount of ltc i should have after 30min mining.
