126  Bitcoin / Mining / what is the best non-doublewide card out there? on: June 24, 2011, 02:00:13 AM
I'm trying to determine what is the best (in terms of highest attainable MHash/s ) non-double width card?

What is the thinnest card if you account for the heatsink/fan?

128  Other / CPU/GPU Bitcoin mining hardware / need help in identifyin a converter cable. on: June 23, 2011, 04:09:00 AM

take a look at:

I bought one of these open box from newegg for $12 the other day and though it was a great buy.  Glad I only bought 1.

If you look at the 3rd picture from the bottom you will see the 3-pin black connector that converts into a regular computer powercord on one end and this 3-pin looking receptacle. 

Problem is, this converter is missing from box...  returning is gonna suck...

Does anyone recognize this converter?  Where can I find one of these?
129  Other / CPU/GPU Bitcoin mining hardware / number of GPUs on linux with 11.6? on: June 22, 2011, 12:23:49 AM
Rumor has it that it can handle more than 8 GPUs?

Has anyone tried yet?
130  Other / CPU/GPU Bitcoin mining hardware / Need a second opinion on 4x 5830 setup running at 301 Mhash/s each on: June 21, 2011, 01:09:18 AM
So I have a system running with 4 XFX 5830s.
Win7 64 bit.
SDK 2.4
11.6 drivers (minimal install)

I'm using phoenix 1.5 from command line against slush.  each of the 4 instances is running at slightly over 301 Mhash/s

All 4 cards are set to 970/350 with 75% fan speed.

all 4 cards are next to each other.  The fan temps are: 76,76,83,64

Attached 1 monitor and using 3 dongles.

The current OC setting appear to be right up at the limits... If I go above 970, system becomes unstable.

One current and strange behavior is that once my monitor goes to sleep, if I "wake up" the system by say moving the mouse, the system freeze and I will need to reboot.  So, I don't touch it... it's been running for days now.

Does anyone have any suggestions or ideas on maybe trying to squeeze out more Mhashes with currently loaded OS?

Side note:  with only 3 cards I was able to run the cards at about 308/309 Mhashes but it was OC'ed to 980-990.  With 4 cards 970 is the highest I can run at as long as I don't wake up the monitor.

Obviously one option is to never let the monitor go to sleep... but this in itself isn't a big issue, I can leave it be....

I'm more interested in hearing some suggestions on how to squeeze more out of these cards...

phoenix is launched via a batch file:

phoenix.exe blah blah blah
go to start
This takes care of phoenix.exe crashes.

Additionally, I have a scheduled task that kills all phoenix.exe instances every 30 minutes. and above batch files just launches it anew.

Thanks for your input!

131  Bitcoin / Bitcoin Discussion / Close to US$500k stolen in first major Bitcoin theft on: June 17, 2011, 09:43:54 PM

In the first Bitcoin theft of its size, a user has lost 25,000 BTC — or nearly $487,749 at today’s market rates — to an unknown thief.

While the Bitcoin community has always been quick to point out that it’s harder to forge a Bitcoin than to forge a dollar, it’s quite easy to take someone else’s Bitcoins: all you have to do is gain access to their computer’s hard drive. Once you’re in, stealing Bitcoins is easier than taking a wallet in the real world, and there’s no recourse for getting them back.

That said, it is possible to verify the movement of funds to ensure complainants are telling the truth due to Bitcoin’s public nature — services such as BlockExplorer allow users to see every transaction that has ever occurred through the network. The receiving account in this case, for instance, can be seen here.

As a decentralized network with no authority and no identities attached to the addresses used to send and receive Bitcoins, once Bitcoins are stolen they’re as good as gone.

While at the time of this writing the BTC is trading at $19.51, I wouldn’t be surprised to see their value drop over the course of the day as this news spreads.
132  Bitcoin / Bitcoin Technical Support / issue with adding a 4th 5830 with PCIe x16 extender on: June 17, 2011, 07:59:13 PM
- 890FXA-GD70 mobo. plenty of power

- using PCIe x1 & x16 Extender from:

Windows7 x64. sdk2.4 video driver 11.5 or 11.6

The system is completely unstable.  BSOD (from video driver) or it simply freezes.

I don't even begin overclocking anything (not enough time to get that far before issues occur).  Stock settings.

if I take out the 4th card the system runs just fine... not using crossfire.

Does anyone have any ideas about this?  Have you experienced this too or have you heard about it?

133  Bitcoin / Mining / quick question regarding 6970 sapphire card on: June 10, 2011, 06:11:49 AM
1. is it dual GPU?
2. hardware comparison has a range of 323 through 423 Mhash/s.  is this per GPU or for both GPUs?
134  Bitcoin / Mining / Comments/Suggestions on my project on: June 07, 2011, 04:30:58 PM
So, I decided to build a rig...  It is just for fun and learning about bitcoin mining.

Here's what's on order:
- TJ11-BW (Black) case
- MB MSI 890FXA-GD70 AM3 R
- Lian Li Dual Power Supply Adapter Cable
- SILVERSTONE ST1500 1500W ATX12V/EPS12V SLI Ready CrossFire Ready 80 PLUS Silver (2 of these)  (for attempting to run 5-6 6990s later)
- 64GB Crucial m4 2.5-inch SATA 6GB/s
- 8GB Kit (4GBx2), Ballistix 240-pin DIMM Upgrade for a MSI (Micro Star) 890FXA-GD70 System
- XFX ATI Radeon HD5830 1 GB (ordered 6)
- AMD Phenom II X2 555 Black Edition Callisto 3.2 GHz
- Cooler Master RR-910-HTX3-G1
- I'll get some fans at a store once I see how this all fits together...
- will get some PCIe x16 cable extenders as needed

I'm thinking of loading win7 64bit on half the drive, and then loading ubuntu on another 8GB partition and have some more room for other OS'es to experiment with.  Ofcourse, booting from USBs for other OS flavors is always an option if the drive gets full.

My goal is to have 5-6 6990 running whenever they become available (perhaps a few months later) if this is possible.

I will stay away from crossfire and will just plugin dummy plugs (this should cover all OS'es).  Will probably flash the video BIOS after I find a comfortable and stable OC combination on the 5830s and other cards.

Do you think I should consider anything else?  Willing to try/experiment if there are good ideas out there...

What do you think will give me trouble and how did you solve it?

Will try to provide updates on my project so that others can benefit from my experience with this...
