Hello!
Why my Pitcairne HD7850 GPU is "Unknown" in E@H Computer ptoperties? =((((
It is very powerful video card. It completes a work unot almost 6 time (600%) faster than my previous 5750.
I don't like it to be "Unknown". =((
U do usually study my results with a computers that calculate the same task in one workunit - I compare speed of completiotion, configuration of PCs and so on.
It is not good that people that do the same can not know what VC shows such a magnificent results (I just saw GF560 took 20500 seconds a task, that was completed by my HD7850 in 2901 seconds, though their cost is equal.)

Hi,
sorry, I cannot answer your question, but I took a look at your crunching times. These 2650 sec's, how many wu's are running together on one card? I plan to replace my HD5850 with a card in the rage of 180 - 200 € and I'm looking for concrete numbers to compare against GTX660.
Regards,
Alexander

I can think of two possible reasons - BOINC version and driver version.
If you take a look at this particular host, you can see it has two properly identified 'Pitcairn' GPUs. You can see that both the driver version and BOINC version are different to what you are using but I would think that driver version would be the key thing to update to get your card properly identified.
Be very careful in comparing your results with those of your wingmen. It is possible that you may find examples of very inefficient setups. It would be surprising if any AMD card was significantly outperforming a comparable NVIDIA card to the extent you are suggesting. At the moment, NVIDIA is King at E@H. That could change in the future as the OpenCL app matures. If you want evidence of this, just browse through the top 200 hosts in the top hosts list and see how many AMD cards you can find.
Edit: I just checked your host again and noticed that I misread your driver version when I wrote the above message. Your version would seem to be the same as the other one I linked to so I don't know why yours is being listed as 'unknown'. BOINC does the identifying so you could try the newer BOINC. If that doesn't work then perhaps it has something to do with your GPU BIOS. Maybe you could check if there is a newer version that might fix the problem.
Cheers,
Gary.

hello! This result I achieve when run 2 wu together. GPU load is 90%+ in this case. Considering going back to one wu/time - the noise from 90%-loaded vc is too audible at night.

Hello! All this is very-very strange. =( Just changed Gigabyte 7850 to ASUS 7870 - and the vc in configuration is still "Unknown radeon". BOINC client is the latest. Do you know when info on site is renewed? maybe it's just not up-to date?
PS In the events log in BOINC I see that my vc indentified correctly (both times)

You're NOT running the latest Boinc client, you're running Boinc 7.0.28, it may be the latest 'Recommended' client, but it is not the latest, that being 7.0.36 at the moment.
Pitcairn identification was added to Boinc 7.0.29, but since that version was never built for windows, and 7.0.30 was retracted, the earliest you can run and get correct identification is 7.0.31:
