Hey guys, graphics company went bust that I knew the owner quite well from. what kind of Ghash/second could I get from NVIDIA Tesla Server racks populated with NVIDIA Tesla C2075.

One rack is also populated with 5 nVidia Tesla K10 in a 5U configuration.

(nVidia Tesla K10

8GB 5GHz GGDR5 PCI-Express GPU Computing Accelerator

3072 CUDA Cores, 4.58TFlops Peak, 320GB/s Bandwidth)

Not sure if even one... mining with nvidia is a bad bad bad bad idea.

Even with the Tesla power? These are pure GPU servers.

Now you might want to take a look at what CoinLab is creating.    They are building a client that you run and earn bitcoins.  It will performing computing tasks, not necessarily be used for bitcoin mining.  They are still working on the HPC client (which will do much better on NVidia than AMD).  Currently, they just operate a mining pool though.

Well when that client comes out, I may be tempted to use it.

The tesla aren't as awful as the rest of the nvidia cards at mining.  Certainly not as cost efficient if you were purchasing them for only that purpose but if you already have them and want to play with them you can probably crank out some decent hashes.

This doesn't have the C2075 but it has a C2070 at ~750 Mhash/s so each card is around the equiv of a amd 5970 or so.  If you plan on running them in mass you should try getting a read on how much power draw they have while mining.  I imagine it's going to be pretty expensive depending on your electricity cost there.

Judging by the specs here (http://www.nvidia.com/object/workstation-solutions-tesla.html) I find that very hard to believe, and would love to see valid proof of such a hashrate from a nVidia card. It has the equivalent cores as a 560ti (http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-560ti/specifications) or a GTX470 (http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-470/specifications) except running at 1.15Ghz and I would guess <150Mh/s each.
The 6GB of VRAM makes no difference in Bitcoin mining performance.

The k10's seem to be equivalent to the GTX690 (http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-690/specifications), and would get <275Mh/s each tops!

I can confirm the Tesla that is listed does reach around 740 to 755 MHash each card.

How?

The most I can squeeze out of a C2070 is 150M.

the S2070 hits around 750Mhash/sec, not the C2070. I work for HP and brought home a variety of NVidia workstation cards to test out (have a friend in the former Personal Systems Group - Now Printing & Personal Systems business unit who was able to get me some demo cards) including a Tesla C2075, a Quadro 6000, and  neither of them produced anything spectacular. The C series Teslas are a single HPC graphics core, while the S series Teslas are multiple HPC graphics cores on a single card, hence why the S2070 is able to produce around 750Mhash/sec. Unfortunately, my friend was not able to get me an S-series card to screw around with. Not to mention, to fit those cards into my gaming/mining PC, i had to MacGuyver a bit to remove the full-length brackets and add the special extra power connectors....those things are farking beasts.

...and cost a pre-tty Pennie too! Unless you already have the access, NOT worth it for mining. As I said before, the C2075 is essentially a 560ti with an ass-load of VRAM, specialized for 3-D modeling applications using floating point integers (IE. not what Bitcoin mining uses).

Thanks, That explains the "(-gpu=0 through -gpu=7)".
