1  Economy / Currency exchange / WTB up to 5 via Paypal - Business Verified Account + Referrals on: July 06, 2013, 06:06:18 PM
Buying up to 5 BTC @ Mtgox rate with Paypal.  My Paypal is a Business Verified account, will send as gift so chargeback is not possible and I can prove original ownership if necessary.  

See my referral thread: https://bitcointalk.org/index.php?topic=240818.0

Note to post count boosters: Please skip your typical "BEWARE OF PAYPAL CHARGEBACK" post.

As the title says, I want to purchase 2 BTC for USD @ Mtgox rate.  I will also accept BTC-E code.  I'd like to pay via Paypal.  My Paypal account is Business Verified and I have references on this board of people I have purchased BTC from with paypal.  I will do escrow as long as the service is reputable.
4  Other / CPU/GPU Bitcoin mining hardware / Unresponsive Motherboard Problem on: June 10, 2013, 11:36:17 PM
Today I was installing an additional video card in my mining rig.  Booted up, everything worked fine then I restarted to configure something.  Upon reboot the system became unresponsive.  There is a power button/light on the board that shows it's getting power.  But instead of having to press the power button to boot the system, as soon as the PSU is turned on the CPU fan starts spinning and the system is completely idle/unresponsive.   Pressing the power button on the motherboard does nothing.  The CPU fan spinning is the only activity I can see and it will keep going indefinitely.  The only way to stop it is by switching the PSU off.  I tried a hard reset of the bios, pulling all components out and reseating them.  It seems only two things could be damaged, the motherboard or the PSU.  I briefly tested the PSU with a different motherboard and that board was responsive so I doubt its the PSU.

Did I fry my motherboard?  What could have caused this, static damage?
5  Bitcoin / Mining support / 7850 Stability issues after switching OS on: June 04, 2013, 12:00:11 AM
I have a Sapphire 7850 which was being used for mining LTC.  I was using BAMT and the card mined @ 350kh/s for days on end with no issues.  I changed the rig's OS from BAMT to Xubuntu.  I tried running CGMiner with the same settings/drivers as I was using in BAMT but the system resets after 15-20 minutes of mining. I am using the following settings: I=19, TC=8192, gpu-engine=1100, gpu-memclock=1350.  After experimenting a bit, I found the card will run stable in Xubuntu if the intensity is at 17 or lower, but this is a loss of at least 100kh/s compared to what I had been getting.  Cgminer reports a temperature of 67C and HW:0.

Why would I have stability issues in Xubuntu with higher intensity setting but BAMT runs fine?  What could be causing this?  Thanks.
6  Economy / Currency exchange / WTB 1-2 BTC for USD on: June 01, 2013, 10:47:10 PM
I am looking to purchase 2 BTC with USD.  Currently the best method of transaction I have is Paypal.  I realize I'm a fairly new member and Paypal isn't considered the most safe method since payment can be reversed.  However my Paypal is a Business Verified account, I can send the USD as a gift (gift's non-disputable so can't be chargebacked) assuming you are a trusted member and provide evidence that I am the account's owner.  Also I'm open to other methods of transfer that utilize paypal as well as escrow.
7  Other / CPU/GPU Bitcoin mining hardware / Grounding when building a Custom Rig on: May 29, 2013, 07:43:27 PM
I've seen many different types of custom rig containers.  Some very well thought out and constructed with care and others nothing more than a milk crate.  When building a custom rig, how can I ensure that key components are grounded properly?  It is my understand that in a standard computer case the metal screws/risers that connect the motherboard to the case are grounding the motherboard.  How is the motherboard grounded when making a custom case, where lets say the base the motherboard rests on is wood or plastic?
8  Other / CPU/GPU Bitcoin mining hardware / Strange Problem when moving to new Motherboard on: May 29, 2013, 03:55:50 PM
I recently changed my rigs motherboard from a ASRock FM2A85X to GIGABYTE GA-F2A85X.  Currently using a Sapphire 7850 and 7950 and an APU, running BAMT as OS.  I'm have very strange issues with stability and temperature.  When I start mining, the cards may work for a minute or two and then the system will reboot.  At this point the temperatures are well below acceptable levels, under 70C.  If it does get past the first minute or two, the cards will get gradually hotter and hotter up to 80C and then the systems will restart.  If I disable the APU/7850 and lower the intensity of the 7950 from 19 to 13, it will run stable but the temperature gets higher than when I was running everything on the ASRock motherboard.

The cgminer settings I'm using are the same as what I ran while using the ASRock motherboard, so I don't think it's that.  And the space the two cards have between each other on both motherboards is the same, so I don't think they are ventilated any differently.  And I should note that with the ASRock motherboard, I had this rig running for days at a time and it was stable at good temperatures (~72C).  Also I've been through the BIOS to see if there's any type of temperature cutoff thing and I haven't found anything.

What could be causing the issues I'm having? I've included my cgminer.conf just in case there's something weird going on.

"shares" : "0",
"kernel-path" : "/usr/local/bin"

Edit:  I've also tried mining under Xubuntu 13.04.  The system appears to be stable at Intensity 13 (which means a loss of 350 Kh/s) with the temperature for the cards at 71-73C.  The 7950 fan is running at 2800RPM, the 7850 at 3800RPM.  This is still hotter temperatures and faster fan speeds than what I mining at 20 intensity on the ASRock motherboard.  What could be causing such a difference in temperatures between the two motherboards?
