i just built a new computer. Asus P6TD Deluxe MoBo.
intel Core i7 920 cpu, 12 gigs DDR3 tri channel RAM
Nvidia video card with 1 gig DDR3 RAM. Instructions
SSE (1, 2, 3, 3S, 4.1, 4.2 ) EM64T, VT-x.
What is the best app to run ?

It is usually a tossup between SSSE3 and SSE4.1.
I would go with SSSE3.

I would go with SSSE3.
Given he has 12Gb i'd assume it has a 64 bit OS, so go for the 64 bit multibeam app. As Arkayn suggests the SSSE3 variety. Unfortunately there isn't one for Astropulse. It seems seti multibeam is somewhat quicker in the x64 version.

Same here. All mine have been upgraded now.

Running a standard non optimized client new computer
has accumulated 15,465 credits in 4 days. i'm going to
stay with this setup for a week or so and see how it goes.
i will certainly run an optimized client soon, just interested in
documenting precisely how much improvement i get
from it.

AFAIK, you can let run 32bit software on 64bit OS.
I don't know what's included in the 64bit Lunatics Installer, but I guess the AP app is also there.
EDIT: If you installed opt. apps the CPU RAC will be the double. Also the performance of your GPU will increase because you will not calculate VLAR WUs (< 0.12x AR) which will make sluggish your PC.

RAC is imprecise by its nature. You could run offline benchmarks with stock and opt apps to see the difference.

You can normally run 32-bit apps on a 64-bit OS. What you can't do is run a 64-bit app on a 32-bit OS.

If i add a 2nd video card does it need to be the same as the 1st ?.
What percentage of the number crunching comes from the GPU
as opposed to from the CPU ?
What sort of gain could i expect from adding a 2nd video card ?
Just downloaded and installed Multibeam optimized app for
64 bit SSE 4.1

Nope, it doesn't have to be the same, but Boinc 6.10.x will only run the most capable by default,
you'll need to make a cc_config.xml (you don't have one by default) just copy the following, and paste it using Notepad,
then save it as cc_config.xml making sure it doesn't have a .txt extension, drop the file in your Boinc Data folder and restart Boinc.
<cc_config>
<log_flags>
<sched_op_debug>1</sched_op_debug>
</log_flags>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

Depends on the GPU / which project the GPU/CPU are running, expect some where between 50% and 90% total RAC coming from the GPU.

i currently have a NVIDIA GeForce GT 220 (1024MB) driver: 19045 video card.
Is there anything better in the USD $100.00-$125.00 price range i can add
using the cc_confic.xml file claggy was kind enough to supply ?
i may end up overclocking the CPU and/or GPU ( s ), but not yet.
-
You have many options:
1) Keep it and with those $100-125 get a second card, 9800GT or GTS250 if the price is right
2) Sell it and add the money you get to the other $100-125 you have and get a GTS250 or even a GTX260 if you can reach it.
3) Stay as you are, keep your $100-125 and start saving for the new generation nvidia cards expected to come out in the March-April timeframe. Then you can also sell your current GT220 to add to your money for the new card.
If you want performance right NOW I would go to option 2. If you can wait a little I would definitely go to option 3.

i can get a Sparkle GeForce GTS 250 Video Card - 512MB DDR3, PCI Express 2.0,
(2) Dual Link DVI, SLI Ready for $129.95 now

My BFG OC 250GTS has finally crossed 6000 RAC using a test hybrid GPU app in Seti Beta. How I got it was Frys.com had it listed for $xxx.xx Bestbuy.com had it listed for $xxx.xx with a price match. I carried in the print screen for the price match and the 250GTS 1 gig cost me $125 and pennies plus tax. The other day I stopped at Frys for a MB and could not help myself went back and found an open box EVGA 250GTS for 123.00 the only caveate is that you should have a "Good" 475 watt power supply for the G92 chips
So other than cores, the 250 has better timings than the 260 or 275
I would be curious to see what the 220 would do. But that would take a month of doing Seti Cuda only on the GPU.
So as mentioned RAC is a fickle thing, the best is seeing how much credit it can produce in a month and then divided by 30 days.
http://boincstats.com/stats/host_graph.php?pr=sah_beta&id=16588
and pendings for the machine is over 70000
To make matter worse it is running Aqua on the CPUS which is fairly intenisve but give up time to the GPU fairly nicely. However I am losing about two minutes per Cuda WU (0.40 AR) which adds up.
That is objective as I can be. The machine is producing over 12000 cobblestones/day

hmmm, BFG GeForce GTS 250 Video Card - 1024MB GDDR3, PCI Express
2.0, (2) Dual Link DVI, SLI Ready $129.95 at Circuit City. Perhaps put that
in main machine and put GT220 in one of my other machines, if any can use it.

There are options, you just have to find them.

i just got my GTS 250 video card ( 1024 MB GDDR3 ). i will be installing it on my
ASUS P6TD Deluxe motherboard using the cc_confic.xml file claggy
suggested. Is there any preference as to which slot the 220 and
250 should go in and is there any additional configuration needed ?

I would put the 250 into the slot closest the CPU. There it will be most effective. As it is installed, reinstall the nvidia drivers as some features/functions will not take effect until that happens.
If you have a machine that will support one of the other video cards that would be better.

Windows Vista/Windows 7: C:\ProgramData\BOINC\
and it'll be hidden, so you'll need to unhide it.

the sched_op_debug flag is showing that you're asking for GPU work, and how much work you're asking for, that you're got an idle GPU without any work,
that the server didn't send you any work, and that two tasks got reported correctly,

What messages did Boinc show before you moved the GPU's about?, Did it show 'Config: use all coprocessors' on start up?, did it say one of the GPU's was not used?
What does it say now?
The cc_config needs a 'Start' Options tag, as well as and 'End' Options tag, so:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

i don't recall and did not record what it said before moving the cards.

Can we have a link to your host please?, snipping bits out your startup messages doesn't help us find out why you're not getting any Cuda work,
and if you're ever managed to do any, there's Plenty of Multibeam work available, so that's not the problem.

You do have a Cuda app in your app_info?, as Boinc 6.10.18 will still ask for GPU work even if you don't have a Cuda app referenced,
as all your optimised results are CPU results,
Go grab the 64bit installer and the Cuda 2.3 DLL's,
Shut Boinc down, install the SSSE3x or SSE4.1 (SSSE3x better on a Quad, SSE4.1 maybe better on a Dual Core),
make sure you also select the Astropulse_v505 app and the Cuda V12 app,
when that's done over-write the Cuda dll's in your Setiathome project folder with the new Cuda 2.3 dll's, then restart Boinc,
touch wood you won't loose any CPU work.
Edit: you're got a lot of lost 6.03/6.09 work, so it might be better if you go to your Seti project preferences, select the following to No:
Use CPU
(enforced by 6.10+ clients) yes
Use NVIDIA GPU if present
(enforced by 6.10+ clients) yes
Click update, Now Detach and Reattach (you won't be sent any 6.03 or 6.09 work, so you can't loose it in the next step),
then install the apps with the installer, and the dll's, reset your Seti preferences to yes, then click update, and hopefully you'll get work.
Claggy
Edit: If you get Astropulse_v505 wu's, it'll help keep the wu count down a bit, and probably help Boinc's performance with lots of wu's.

Hi, I followed the above instructions when I added my 3rd GPU card but my Boinc still only sees 2 cuda cards. Windows and GPUZ and nvidia control panel all see a GTX 285, GTX 275 and the GTX 260 I just added but boinc only sees

Can't get it to see the GTX 260....

Do you have the cc_config set to use all GPU's?
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>
-
Yep, I have 2 working just can't get the 3rd even got a new 1250 Watt PS today. Here is my cc_config...
<cc_config>

Dummy plug, screen extended?
-
Thanks, I had forgotten about that....Guess I need to run to Radio Shack real quick.....
-
Worst part is I only have 1 video card in each of my 2 machines and they are ATI's.
I am thinking up these things from memory.
-
Well one more thing....Do I just turn off my computer and put a dummy plug on the 2 GPU's not used and they will be seen or are there any other settings like use screen on all monitors or something?
-
I think you need the plugs on, then extend the screen to all three cards.
If I remember that correctly.
-
Cool I have 2 dummy plugs made will give it a try in a bit and let you know, now that I think about it I had 2 monitors when I originally set this up to run 2.
-
on my setup:
Rig1:
GPU1 = monitor
GPU2 = PhysX
GPU3 = dummy plug (monitor extended)
Rig2:
GPU1 = DVI connector
GPU2 = PhysX
GPU3 = VGA connector from the same monitor
-
Yea, it worked, I monitor and 2 dummy plugs!

When i last looked, TouchuvGrey's computer was only displaying one GPU, when he had two earlier,
so he might need a dummy plug too,
I also thought his GTS 250 tasks were a tadge slow compared to my 9800GTX+, i wonder if the Cuda 2.3 dll's got installed?

i was wondering about the GTS 220 card not showing also but have been
otherwise occupied the last few days. Sometimes after a cold boot the 220 card
shows and the computer stops responding. As far as i can tell the 2.3 dll's have
installed though it took me a while to get that done.
What is a dummy plug ? where do i get one and how do i install it ?
-
Just Google 'Dummy Plug', the first couple of links should have pictures.

I noticed after installing the 3rd GPU that the middle card a GTX 275 was getting up to 80C. Didn't like that and noticed they are right on each other...I took the rubber protectors I got on the ends of Sata Cables and used them to shim between the cards and brought my temps back into the 60's. My only problem now is I keep losing my mouse to the extended monitor....LOL
-
Go into Monitor configuration and drag the 2 extended monitors down until they only connect at the very bottom of the actual screen.
-
No dummy plug here yet, but i did happen to have a "spare" monitor
that i could plug in to the GTS 220. Shut down BOINC, added the monitor,
restarted BOINC. It's now showing both cards. Now if they can just get
the A/C fixed at SETI central.
-
Back to just one card. Removed the GT 220 and running just the

i've been getting for the past few days,
