I suspect that our fine Doctor and the district in general would have taken a very different view if Nez (and by association the district) had been lucky enough to contribute towards the finding of ET. The PR would have gone along the line of the steadfast support the district and management had given Nez in his and Setis quest.

And I will startup my GT 240 in few hours :)
MSI with GDDR5, and I also need to see how this new generation is fast ( or not)


I started BOINC just prior to frying my BIOS. The results were not encouraging - CUDA 2.3, PhysX disabled:

NVIDIA GPU 0: GeForce GT240 (driver version 19562, CUDA version 3000, compute capability 1.2, 512MB, 279 GFLOPS peak)

The GFLOPS are 15% less than my 8800GS on 19170. I didn't get to see how it would crunch though.

Mine is apparently (haven't seen it yet) a Galaxy 512mb GDDR3. The specs are in many aspects the same as the 8800GS I am currently running. I will be happy if I get performance similar to a 9800GT! We can compare notes on Monday...

My GT240 has finally cleared customs. With a bit of luck, I will be putting the system together over the weekend. It will be interesting to see how the 195.62 driver behaves/performs with a "new" generation card - even if it is relatively weak.

Good luck on your system I am getting a new card also. Sure is fun.


Fun it is. Always a bit nervous about firing up a new machine. Never know if the mobo is going to "beep beep beep"... Anyway, the GT240 was the last component required before I could start it up. Decided to wait and see what Fermi looks like, though XFX have been tempting me badly with their new HD5970 BE.

Tilera will be releasing a 100 core CPU early next year. Unfortunately not on x86 platform and won't run windowz. Apparently x86 programs will just require a recompile to work. Overall computing power expected to be 4 times that of the i7 975XE, using just 45 watts. It would be exciting to have a 3rd mainstream CPU manufacturer.

I though I was imagining things. I "upgraded" my nVidia driver to 195xx (beta) version a few weeks back on a single card. The wall clock times went up from about 25 minutes a WU to 30 minites. I then re-installed the 19107 driver. Unfortunately, my times did not go back to the 25 minute mark. I was just testing a VGA dummy (thanks to Sutaru) and noticed that the nVidia control panel had enabled PhysX. I had not noticed that as an option before. I have disabled it but it is too soon to tell if that was the problem.


It appears that disabling PhysX has returned the wall clock timings to 25 minutes.

I managed to get Cuda 3 with the latest drivers to work but the outcome is rather exciting..

Can't really see if i'm benefiting lower crunch times but sometimes i seem to get higher instead.

Hope this isn't a scam that nVidia is trying to get an edge with fermi cards.

If a gpu isn't up to par what do you do to make it look better? Lowering the performance of the previous part when using same driver models stating that they have a total of 250% increase here but doesn't mention that previous cuda and driver set increases performance compared to the newer version by 50% compared to the newer revision.

Hope i can give you more accurate results later as boinc stabilises.

Kind regards Vyper

Edit: I am also a little worried about Fermi relating to the GeForce line of products. I suspect that the Cuda/GPU processing capability will not match that of the Tesla line. The initial Teslas were based on geForce (280 or 285 I think) but they have now been built from the ground up for GPU processing. I think that GeForce will get a lesser offering. From what I understand, the GeForce Fermi is being released at least 1 month before the Tesla Fermi. I wonder why that is?

Let's hope the upcoming new hardware releases are up to scratch, and that us poor developers can get our hands on a reasonably priced model soon enough.

Best Regards, Jason


Let me know when the time comes...If I have the cash, I will get one sent to you, on the condition that you send it back to me once you are done.

Ok. That means you "can" connect to Berkeley. As a matter of interest, I get different replying IP addresses from my different rigs. Some end with 13, and the others 18. I can download/update at will.

Next: if you are posting these messages from the PC you are currently working on, check to see if you are using a proxy server. Assuming you are using Internet Explorer, go to "Tools", "Internet Options", "Connection Settings", "Lan Settings". If the "Proxy Server" box is ticked, you are using a proxy server. Note down the IP address -something like 192.28.5.123 and port - usually 80.

Then: if you not using a proxy server, open Boinc Manager and go to "Advanced", "Options". Make sure that the main check box for both "HTTP Proxy" and "SOCKS Proxy" are NOT checked.

Or: if you are using a proxy server open Boinc Manager and go to "Advanced", "Options". Check the main check box for "HTTP Proxy" and enter the proxy server IP address and Port. Make sure that the main check box under "SOCKS Proxy" is NOT checked.

Try download/upload again. You will get a message initially as it seems that Boinc stores one of these messages to tell you that you were last unable to connect. You should get some joy then.

Still having trouble do not know how to ping berkerley or should I alter my drivers. got the old
BOINC can't access Internet - check network connection or proxy configuration coming up after I did the Network today with a proxy which I do not have so I have rebooted the machine and will wait, can anyone help me?


I will try and help you, but I am not going to read the whole thread. First thing, can you ping Berkeley? If you don't know how, go to your Windows "Start" button and click "Run...". In the dialog box that will come up type in "cmd" and press enter. You should get a black "dos" screen. Type in "ping boinc2.ssl.berkeley.edu". You should get 4 replies if you can reach Berkeley and other messages if not.

Not sure how useful this is, but on a related topic...

A (non-Seti) server running Windows 2008 lost its TCP stack due to a similar windows update on a reboot a week or so ago. We had neglected to turn windows update off. There was no uninstall available from Microsoft for this update as Microsoft never release any buggy updates. Our only recourse in the end was a re-installation of the operating system, and everything else thereafter. I have turned of windows update on all my personal computers subsequent to this incident.

If your interest is CUDA crunching and not high resolution video on huge monitors, I'd get the 512MB DDR5 version ot the GT240. It will be noticably faster crunching SETI WUs.


Trying to understand the performance characteristics of these Cuda cards. Are you saying that having faster memory on the card is better than having more memory from a Cuda perspective?
