News: BIP91 seems stable: there's probably only slightly increased risk of confirmations disappearing. You should still prepare for Aug 1.

I have an older GPU, an Nvidia 7950GX2 dual board that I would like to mine with. 

Problem is that Nvidia cards do not support CUDA (or opencl) until the 8xxx and beyond series. 

I know that the hash rate will not be great (maybe 40 mh?) but does anyone have any suggestions on how to get it mining anyway?

I'm not sure if it's possible to mine without CUDA/OpenCL -- how would you pass the data to the GPU to be hashed? And 40Mhash is being VERY optimistic -- my 8800gt got less than that.

From what I've been reading, it would seem that Phoenix miner has the best chance of working with older hardware. Of course that depends on what drivers you can install. I have an HIS x1950 Pro, probably isn't worth chasing the bitcoins to hash with it, but I could learn from the process.

For Bitcoin to be a true global currency the value of BTC needs always to rise.
If BTC became the global currency & money supply = 100 Trillion then ⊅1.00 BTC = $4,761,904.76.

yeah, not too sure how to pass the data to/from the gpu without opencl so I thought I would ask here.  My card (cards?) use the same "unified" nforce drivers as the newer Nvidia Cuda ones, but that was not fully implemented until the next model...
 
I will take another look at the phoenix miner.  I have been up late playing with different miners and drivers. 

Maybe its time to ebay it and buy some parts to make my own fpga miner using the BGA rework station at work  Grin

Most of what I read was focused on ATI hardware, I don't know how far back nvidia could go mining wise.
Maybe an assembly man could put together an INT or 2.  Undecided
