I have a question for the GPU nVidia crunchers,

I have a pc with a 425W power supply so only a GeForce GTX 550Ti
will work. According to this threat it will run MW.
However when I go to the nVidia site, there is no information available about this card. What does that mean?
And which brand do you suggest?

Thanks.

When I went to this Nvidia site, I had no trouble finding a link to suitable information:

http://www.nvidia.com/object/geforce_family.html

Make sure that the Specifications section mentions that it uses a Fermi chip, though - I've seen a few cards at the low end of the 400 series where it didn't, and therefore left an open question about whether those cards are suitable for M@H.

As for brand, I suggest the Palit brand if you need to find information on the length of the card before placing an order. Choosing a model that blows the air heated by the GPU out of the case instead of blowing it around inside the case helps with the GPU temperature.

Choose the Gainworth brand if you want a brand known for poor designs of how to keep their cards cool enough for BOINC usage.

It abort it then it keeps crunching until it reaches 100% then it say computaion errors?

Any help anyone?

ATI 4870 driver version 8.861.0.0
Boinc 6.12.33

Please have a look here.

Yep that site works, but then click on the GTX550Ti and that will have no results. It seems to be the only CUDA card suitable for a 400W power supply, but I would like more information first before buying a card.

Strange - for me, the results were somewhat slow to appear, but no problems otherwise.

If you'd like to reach that web page more directly:

Thanks Robert,
The first link works but that did it earlier too, needs 500W poer supply.
The second link is the one I would like to see but it is a very dark page, with a sort of timer bar in front. Nothing in there is clickable. Neither in IE of Firefox. So stil no joy. Can you see and read the page?

Under IE, I get the same results you do for perhaps 20 seconds. Then, it finally comes up. Depending on what it's doing during those 20 seconds, it might happen slower on slower connections.

The links are then clickable, but the one for Specifications gives much of the text fairly dark gray on a black background.

One of the items visible during those 20 seconds is a rotating arrow, like those before some videos.

Guru3d did a good review of the 550ti, summary is at (worth reading the full review):

http://www.guru3d.com/article/palit-geforce-gtx-550-ti-sonic-review/20

They were not overly keen on it, but the version tested was not a GForce version, it was a Palit factory o/c. There is another review at Guru3d, worth looking up in their hardware reviews.

They seem to say it was fine, didnt complain as such, but implicitly recommended the 560 if the budget stretches.

Worth cycling through a few of the card reviews there, they always do a power section to them with a recommended power supply. Just be aware their test rigs are such that they draw unusual power levels - which they do point out - and crudely, a PSU around 50w less than the formal recommend would still do the job. Its all well laid out in the PSU section(s)

Every MW WU I have crunched lately is in error or invalid. I have no idea why. My several PCs use GTX275 and ATI 4850, 4870. Formerly, before something entirely unknown occurred, I was happily processing for MW. Sure would like to again. Here's an example of a CPU WU (this PC has GTX275 which also is erring):
http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=48449026

And here, on a different PC, an ATI 4870 WU:
http://milkyway.cs.rpi.edu/milkyway/result.php?resultid=66604679

Can someone steer me in the right direction?

BTW: I am happily crunching for several other projects.

Thanks Art

You need to update your mw apps.

You need to update your mw apps.

OK, that's a start. Where are the apps and how is that done? When I began working for MW the apps simply got installed. Is there a regression where now I have to do something?
Thanks Art

If you're still using that method, and not certain methods of setting parameters, the apps should automatically be updated to whatever ther workunits were designed to use.

Unfortunately they didn't, although my network is connected 7/24. What did happen is all of a sudden all WU were either invalid or errors and MW (rightly) stopped sending me work.

I think I'm OK for now. Used Remove in BOINCmanager to remove MW, then reattached. Now I seem to be processing with stock apps. After I get a day or two history of success there, I'll try to install the optimized apps which I've never used.

Question: I see the optimized apps come with the app and a appinfo.xml. Do I just empty the MW cache, place the two files in the MW folder, and restart mw? (if there is an instruction sheet I didn't find it)

Thanks Art

Using an appinfo.xml file is one of the methods of setting parameters that stops automatic downloads of new app versions, so expect to have to do it manually for as long as you use that file.

I haven't found an instruction file either, but here's a thread relevant to how to do it for another project:

The optimized apps are the same as the stock apps, only with the addition of an app_info (and an description?).
As long as you don't have any problems with the stock app, you be ok.
If you get the max elapsed time exceeded error, try with the app_info.xml.

OK Thanks to all. Will just observe for now, see if I get completed and credited WU. I have a Nvidia and a ATI PC working solely on MW now, should have results soon.

I use KWSN apps on SETI but had not known optimized apps existed at MW...thanks for the help.

Regards
Art

If you get the max elapsed time exceeded error, try with the app_info.xml.

..And that's exactly the result. All WU still error out.

By "..try with the app_info.xml" do you mean from this site?
http://www.mpits.net/opt_mw.php

Edit: I installed the optimized app and appinfo.xml from http://www.mpits.net/opt_mw.php, the SSE4.1 version which CPUZ says my Q9650 will do. The GPU is GTX275, driver 275.33. MW downloaded only separation apps. Every one completed in one second with this:
Stderr output

Anyone help resolve this?
Thanks Art

Meanwhile back to SETI, Einstein, Constellation, Collatz all of which are running fine.

You can add an AMD HD4970 to the list.

Sorry, those apps are for CPU, not for GPU!

Go to arkayn's site, click on the sub category for your OS (Win32/Win 64) and look for the different apps for your GPUs:
Your Q6600 w/ ATI - Windows 32-bit ATI app 0.82
Your X4 955 w/ ATI - Windows 64-bit ATI app 0.82
Your Q9650 w/ GTX275 - Windows 32-bit OpenCL CUDA app 0.82

Win XP might need a little treaking of the app_info to keep the system responsible. But let's get your GPUs working first.

Does anyone know if the FX3800 is compatible, I dont see it on the list, but wanted to see before I spent time trying to congfigure it to work.
