This CUDA crunching new to me.
.
Been considering making use of the newegg offer for the 240 core CUDA GPU upgrade.
.
The offer "PNY GTX 275 896MB PCI-Express Video Card" wiht 240 CUDA cores for under $200.
.
The card likley also requires a power supply upgrade too.
.
Assuming 240 CUDA cores running at 633 MHz, and crunching about 20 hours a day....
.
Is there any estimates about how many credits this would generate ?
.
Thanks, Jack Woolley

I have 2x gtx275's and they turn in about 5k or 6k RAC each crunching 24/7.
That works out at about 8 to 9 mins per mb =14/hr *24=336/24hrs *40=13440.
Or there abouts.6k each being conservative.Not to good at maths lol

In other words, it'll do rather more than adding another 2 cores to your Q9550.

I currently have a 9600 GT and an extra slot on my MB. Can I add another newer Nvida card... such as a 200 series without screwing everything up?
I am running Win 7 64 bit and a Q6600 at 3.1Mhz. 4Gb ram.
I also boot to a seperate HD in Win XP X64 Pro.

When we finally figure it all out, all the rules will change and we can start all over again.

I have toyed around with a couple SLi and Crossfire motherboards and have ran anywhere from 2 to 3 cards in each.....all UNmatched and have never had a problem (even in the Crossfire boards).

For example:

For testing recently, I ran a Crossfire motherboard with a Geforce 9600 GSO 384MB card (that powered the monitor also, 96 Cores), an 8500GT 512MB card (16 Cores) and a Quadro NVS 290 (16 Cores) all at the same time and had ZERO issues. BOINC recognized all 3 cards properly and assigned work units to each of them.

This setup also ran fine on a Tri-SLi motherboard.

On your 'Stats page' it will show ALL Co-Processors as mutiples of your PRIMARY card (your monitor card), but as I said, BOINC will see them independantly and use their real names/models in the MSG Log.

Hope that helps.

I also recently tried running disimilar cards in a PC. GE8600GTS and GE9600GT.

BOINCmgr messages showed I had 2 * 8600 and stats page showed 2 * 9600.

I never quite understood this. I was running BOINC 6.6.36 at the time. It sounds from what you are saying that the stats page was expected behaviour but would you have expected BOINCmgr to have misreported the cards.

Previous versions seemed to show card x, card y.
In 6.6.36 I got two separate lines :-

Card x
Card x

Having said this, everything seemed to work OK both cards crunching.

Cool !

Thanks for the info. Sounds well worth the monney.

I'm looking to start using a GPU as well. I have 8 computers running BOINC and want the best bang for my buck. Which NVIDIA card is recommended for the best RAC? Can I add a card or two to my machine just for BOINC and continue to use my MB video for general computer use or do the video cards have to be active with windows desktop on them to be used? Running various versions of windows PC's (XP, 2000, 2003, etc... all 32 bit)

I'd suggest you start off with a fairly low-end card. Seti doesn't need many shaders so putting a high-end card in doesn't give much advantage. If however you wanted to use it for other projects then it may be worth getting a more powerful card. Just make sure you get a minimum of 512Mb RAM on the card.

I started off with a 9800GT which was fine, pulls approx 100w so not too bad. You can even use it with GPUgrid. These days most of my crunchers have GTS250's. I also have an i7 with dual GTX260's.

BOINC still has some scheduling issues with cuda and then there is the issue of the VLAR work units for Seti. You can use the ReSchedule tool to shift them onto the cpu. BOINC also doesn't like mixed cards in a system, try and keep them the same sort if you are going to have more than one card per machine.

The GTX275 is a long card, approx 10 inches, so make sure you have room to fit it. I bought myself one but the various connectors get in the way so it may not fit.

BOINC blog

ok, say price wasnt an issue. I want to install cards in all my machines for maximum BOINC stats. What would you choose then? All my machines can take large cards. I dont need to use it for anything else...

1) Almost all of my machines support PCI video (except maybe 2 or 3 support PCI-E?)
2) Most are lights out systems so set it and forget it scenerio is best
3) Can I set them up just for CUDA and use my MB video for video?
4) Running latest boinc. Will they detect and use the card automatically or do I need to do something?

@da
get card....

place card in case...

Install drivers from nvidia...

restart
then install latest nvid cuda toolkit.
restart
boinc=open, see what it says.... and it should be ok to go, as long as you don't have PAE checked when you install boinc....


GTX 295 has 2 cores.... it would be the biggest bang for the buck with boinc. all cards gtx 260+ are 10 inches in length.

if you want more on which to buy.... consult the nvidia product page, and whoever you decide to buy from..... newegg...tigerdirect....bestbuy(ugh). i can help you out in figuring it out if you want....

oh, fyi, it's better to use the card for monitor....on-board video runs off some ram which sucks.... unless it's a good board you bought... and installed.

i've got this process down to an art....

Go Georgia Tech.

The machine I might be attaching soon has two of the FX 5600 units.

How fast do you recon each one can crunch a MB? An AP?

pretty quick..... as long as the wu isn't vlar....


AP is not crunched by cuda yet....

my gtx 260 can knock out wu in 15 mins or less. (216 cores)(FOC)

I wouldn't buy a Quadro GPU.
I couldn't find more specs about this GPUs, but I guess the performance would be only like a GTX260 Core216, because of the max. wattage of the Quadro FX 5600.

And ~ 3,000.- $/Quadro FX 5600 is too much.

Maybe one could give more details about the Quadro GPUs.
Which specs and performance.


But.. I would go with GeForce GTX2xx series, because of prize/wattage/RAC.

Quadro's are designed for cad and cuda...not games... although their product line seems like it's beginning to merge...

they have more output's and designed to work on a 25 foot screen... lol!.

I actually took box and looked...

http://www.nvidia.com/object/product_quadro_fx_4700_x2_us.html

That, I know for sure, is what we are running on the suite.

How fast can that go through an MB WU?

Well, went out and bought a GTX260, installed it and wow. I was expecting to have to install optimized apps and such but it went to work right away and I am crunching work units in as little as 4 Minutes!!! (average is around 8 minutes). Paid only $179 for the GTX260 w/ 896MB GDDR3 and 216 cores and I still have to send in my $20 rebate to make it only $159!

The card is huge, and I did install a new 800Watt power supply as well (old one was 430 watt, just under the recommended size but more importantly it didnt have the two 6 pin power plugs for the video card power).

I may just install them in all my machines :)

I had a choice of 600 watt or 800 watt, the price was reasonable ($89). I've had issues with intermitten usb and pc problems so I was changing the supply anyway. All my problems went away after the upgrade. When I took the old video card out I realized why. The card was mounted face down on a tower cabinet. When I took the old video card out he fan was hanging off the video card and even after shutting down the system the card was SOOOOOO hot!

---

Don't forget to check the various circuits you have them running on -- moving from a 400W PS to 800W PS and moving to a card which draws 125W plus will do that. Oh, one more thing, those fast video cards put out a LOT of heat. I know, I recently deployed a few 9800GT cards... Not running GPU for SETI though, SETI, at the moment, has plenty of user processing power for its existing bandwidth.

My system in in my home office. The room has its own AC and I have 6 seperate 20 amp circuits in the room. Power and cooling are not an issue.

One thing I have noticed though. I installed the card and I am pumping out seti units by the bundle. One every 8-12 minutes but when I look at my stats my RAC is lower then it was before? I only installed the card in 1 machine and I am not gaining ground as fast? The graph of my progrsss appears to have slowed dramatically since the card was installed?
