Well the best solution I can find for a low profile gpu is the GTS450 -


http://www.palit.biz/palit/vgapro.php?id=1392

192 cores with a Cuda compute capability 2.1

Is this is good as it gets at the moment?, anyone know of anything in the pipeline?

Hm, ok - I see the passively cooled card that arkayn posted is a single slot with a slim PCB. But Halz's GTS450? That's a standard dual-slot, isn't it?

It is a dual slot but low profile card, what I didn't realise when I posted that was that the card is no longer in production.

So it looks like the GT520 and the GT430 are as good as it gets.

You might want to mention that most of the NVidia GeForce cards are poor for double precision tasks, especially the Fermi cards.

Tesla's:
Tesla C2050 (515 gigaflops of double precision performance) 3GB


The Tesla C2050 costs something like EUR 2.000+ (not sure how much that in US Doller is) and in comparison to the latest ATI/AMD cards has relatively poor DP performance.

For example:
AMD 6950 costs something like EUR 200 and delivers 563 Gflops in DP!

source: http://www.legitreviews.com/article/1488/1/

No wonder that the top 20 computers all use AMD/ATI GPUs.



Wow thanks for that 2 year old review. LMAO!

NVIDIA is the best!

And it is actually true. However, Kepler is even worse than Fermi at DP and SP tasks. At this rate everyone should just settle for some HD 79x0 cards with 4000 GFLOPS SP and 1000 GFLOPS DP for the lower 7950, add 30% to that for HD 7970, and double that for HD 7990 on a PCIE3.0 slot.

Hello,

There is a new chart document with the new gpu supported :

http://developer.amd.com/sdks/amdappsdk/assets/AMD_APP_SDK_Getting_Started_Guide_v2.7.pdf

And this one confirm that i can seat on my 6870 for double-precision :(...

Enjoy ;)

Seat on? Not a phrase I've seen before.

Section 4 appears to say that HD 6870 does NOT have double precision, though.

HD 79nn cards appear to generate more heat than the cooling for my computer room can handle, so I'd like to see more about the relative performance of the cards with DP but lower in the HD 7nnn series.

Notice from server: An ATI GPU supporting double precision math is required

Look, my dear MilkyWay server, I KNOW !!!
I know it already, so why do YOU keep telling me this ???

I have even UN-checked both GPU options in preferences of all MilkyWay profiles home, school, work ... default !

: Use NVidia GPU and use AMD ATI GPU - it is DISABLED.

So, please, why are You (my dear MilkyWay SERVER) stil telling me this? :(

Someone please HELP me, or i will have to KILL the server :D

Thanx a lot

I notice the Nvidia cutoff is the GTX 260. I have GTS 250. I am looking at the specifications and while the GTX 260 has certain features like more cores, higher memory interface width and bandwidth it is slower in other areas to the GTS 250 and the 260 only supports OpenGL 2.1 while the 250 supports 3.0. I have included the specification links form Nvidia are you sure the GTS 250 doesn't qualify?

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-260/specifications

http://www.geforce.com/hardware/desktop-gpus/geforce-gts250/specifications

I want to be be able to help the project as best as I can. I have fairly powerful machine with Dual Core, Dual CPU's with Hyperthreading for 8 CPU's. Maximum memory of 16 gigs and all the hard drives are U320 15,000 RPM 300 GB SCSI Drives with OS/cache/operations each on a different drive to take advantage of the multitasking multithreading options of the SCSI drives.

I believe the important difference is something that Nvidia didn't bother to put in the specifications, either Compute Capability (usually abbreviated CC) or the ability to do hardware double precision calculations.

If you'd like a different BOINC project related to astronomy but more likely to be able to use that card, try:

http://einstein.phys.uwm.edu/
Note that they will have some shutdowns this weekend.

SETI@Home
http://setiathome.ssl.berkeley.edu/
some shutdowns this weekend likely for them too

If you also want one able to use the CPU but not a graphics card, try:

Message 55350 - Posted: 13 Aug 2012, 8:06:43 UTC - in response to Message 55338.  

So turning off the GPU option in settings area would not let me do MilkyWay WU's?

And as second thing. I forced a driver update to the latest Nvidia drivers and I gained OpenCL dll's and I also now have an option on the card in the 3D settings that can be set to be program specific called "extensions limit" which according to the description since it defaults to "Off" says the extension string has been trimmed with the option "On" it will pass longer strings. I think that is talking about precision do you know if that is the case? I remember double precision from my Fortran days 30 years ago.

If neither of those will help I am looking at getting a 295 GTX which is the upper card limit I can put on this motherboard.

I've been on SETI for 11 years, I signed up for all the astronomy ones I could on the 8th when I some from a post on SETI that the BOINC app is supposed resource time share so while I could set profiles for the other machines to different settings I adjust my design station to share time with SETI + 6 other projects.

If it's under 3D settings, it's almost certainly unrelated to double precision.

Milkyway@Home needs HARDWARE double precision support; the lack of that cannot be fixed by a new driver.

Turning off GPU workunits might allow you to get some CPU workunits; try it and see. However, I've seen BOINC refuse to download any CPU workunits until it already has at least one GPU workunit (not necessarily from the same BOINC project).

Also, you might want to measure the length of the space your computer has for graphics cards, unless you wouldn't mind buying a card so long it won't fit in your computer.

I ended up figuring this would be a problem with the card. The GPU on it has worked great with SETI for several years on the GeForce 1GB 250 GTS so I should meet the need for having done something with a GPU and I did get 10 WU's on the 2nd day just nothing since I'll leave the setting with the GPU options turned off and see if I get anything.

But I went ahead and ordered the highest end card I can put in this motherboard and OS which is the GeForce 1.74GB 295 GTX which is on the approved list and the added benefit to me is that has dual GPU's on it each with 240 cores while my current one has only 120 with 1 GPU. Plus the 295 GTX has a whole bunch of other features on it that aren't in the 250 GTS.

Can someone direct me to where I can download earlier versions of the Catalyst software? Running Windows7 x64 and updated Catalyst today to 12.1 and MW is all aborting. Read earlier posts and someone said 11.9 is good. Tried to find it but had no luck. :(

Hi

I have an ati radeon hd 4770 which used to run MW@Home (probably been close to two years ago) but now when I try to run Milkyway@Home I get this message: "Catalyst Driver Version is not OK for Open CL application with this GPU".

GPU-Z shows Driver Version: atiumdag 8.690.0.0 (Catalyst 10.1/Vista)

I am currently running Vista 32 bit.

Can someone please tell me what version driver I need and where to find it? Thanks in advance. Max
