Worth a look for rack case design, it's all in solidworks but I'm sure you could import it

Found my first block for the pool

I have soldered a wire onto the BIOS chip to enable flashing and have flashed with a RBE modified BIOS. it has however made no difference to the performance of my sapphire 1G HD 6950 as I believe the extra shaders have been disabled when the chip was made.

Hmm you will need to do some soldering to unlock that card
I have created an image with the info but can't upload a photo PM me and I'll send you it if you like

No need to crossfire they should work fine separately but if using windows you may need dummy vga or dvi plugs for any card not plugged into a monitor

Running it in a linux box so haven't been able to try afterburner or anything, I will have a look for a signature from another 6950 does anyone know of one with higher than 840 peak GPU?

Site and Mining working for me

I have a sapphire 1G 6950, it is the same no dual bios and bios is locked
I got the soldering iron out and hooked the Write Protect up to VCC and am able to flash the bios
However it appears the shaders are disabled on chip as it has made no performance difference.

I am still curious about modifying the GPU overclock limits by flashing but am a little reluctant due to having only one bios chip
Has anyone increased the limits by flashing?

Supa what type of card were you reflashing?

Hi All,
I've just read this article on ars http://arstechnica.com/business/news/2011/06/amd-launches-second-fusion-cpu-gives-glimpse-at-future-of-cpugpu.ars
I was wondering if this would be a useful CPU for bitcoin mining once it becomes available, they say it has 400 shader units which would surely be capable of quite a few MH/s

It seems that most miners don't bother with utilizing the CPU due to the KW/h vs MH/s problems but with a CPU being a necessary component would it be worth using one of these for a mining rig and gain that little bit of extra performance.

Haha can now finally post

PM'd this to walidzohair but thought I'd post it for the benefit of anyone else that was having issues

I had the same issue with a HD6950
It was unable to get EDID information from my 19" screen after installing the driver so it was trying to drive it at 1600x1200 resolution
So I used Ctrl+Alt+F1 to login to a command prompt
sudo nano /etc/X11/xorg.conf

Then added Modes "1280x1024" "1024x768" to the SubSection Display
1280x1024 is the resolution of my display 1024x768 was just for backup

So the section looks like this
SubSection "Display"
       Viewport    0 0
       Depth        24
       Modes "1280x1024" "1024x768"
EndSubSection

Obviously pick a mode that suits your screen save the xorg.conf and restart

If you are looking for any other clues you can scan the xorg log file but using something like
cat /var/log/Xorg.0.log |less

Hope it's helpful

That's awesome, You would think that the early adopters of bitcoin would be a little internet savvy

It's all just a cost benefit thing. work out the cost and the benefit and if the cost out weights the benefit then yes it is too late

The international aspect buying stuff on the internet can be difficult when so many of the retailers are based in one country and you are based in another. It would be nice to see these boarders broken down by a common currency

Care to elaborate on any of the problems you have had?
I'm sure there are people interested in making bitcoin more accessible

Yeah I've been reading the forums for weeks as guest but now want to post should've read all the rules first

Wonder how many bitcoins will get lost on flash drives...

I was seeing something similar on block 127833 it was showing a value then when I checked again it showed none, now the value has returned although I can't confirm if it remained the same.
I assume there is no issues with the system that will affect our confirmed returns?
