For anyone, a good PSU is essential, for Crunchers its a no brainer. For example, taking your excellent 430w antec. By comparison, an el cheapo 430 non certified, is likely running at 60% efficiency. As a hypothetic, assume the el cheapo runs at a suicidal 430w (always plan a 25% reserve for PSU output not its rated output). At 60% efficiency, that would draw 716w from the mains. Thats 210w more than the antec ...... work that out at 7x24 crunching at price per kilowatt hour .... A quality PSU literally pays for itself many times over its usual 5-10 year life compared to el cheapo brands.

This post needs to be pinned, bolded, posted to the main page, what ever it takes to make as many peeps to get to read it. Absolutly right on the money, everyone who cruches with his GPU needs to check his PSU, you will be surprised how your bill drops with an efficent supply!
btw, nowadays cheap and efficent PSUs are available from OEM manus like FSP, who reach 85% efficiency also.

That isnt really an option since usualy when the PC is on... im working on it.
So what im looking for is a way to limit the GPU usage to say 75% - or whatever is needed to have a lagfree Windows.

*bump*

I would like to know too, if and how it might be possible to lower the load on the GPU? Im working on my PC and the input lag is very annoying. Thx in advance for any help!

Wrong, ATi 4770 has double precision. 4730 maybe also ? not sure right now.

Let me try to understand this.
You are using credit as a way to determine whether or not your computers are being use the most efficiently?... Really?...



What else do you have to compare? And there are cases where it works pretty good. Example: A Phenom II vs a C2D, projects Rosetta & SIMAP: in Rosetta the C2D will go ahead with ~33% credits/per hour, in SIMAP the Phenom II is slightly faster - in most other projects the C2D is faster then the Phenom II, but the difference is way smaller then in Rosetta.
So its easy to make the statement: The Phenom II is most efficent in SIMAP, while beeign bad at Rosetta, on the other hand the C2D is very efficent in Rosetta, while rather poor on SIMAP. This statement has only been done over creditcoparison - note: I dont care which project gives the machine a higher RAC, thats a total different story and goes into the "cross project credit parity" and it isnt what im talking about.

btw: your comparisions to "socialism" are way off, they dont fit at all, and by no means in this general form as you are throwing them. Id be interested what your idea behind socialism, in general, not in meaning of BOINC, is. PM me if youd like to discuss.

You cant compare different kind of GPUs... its like stating "my Phenom x4 955 in XXX makes more credits then my Athlon 1400 in YYY, so XXX is the best paying project..."

Not a new move from nvidia, sadly. Looks like the relabeling works very well, else they would have stopped this "experiment" after the 8800-->9800 relable.

If you ask me, the last really good nvidia card was the 7xxx series, I had 2 7900GTs (one still around here) - fast, not too expensive & silent.

There is a nVidia 9400GT for PCI , and ATi 2400 Pro aswell. thats about the best you get for PCI and I doubt there will come any better in the future.

Even if, thats way overrated. I have 22A on 2 12V rails, thats more then a lot of 500w PSUs offer.
Also, im pulling about 160w when im having CPU & GPU on full load.
This recent wattage race is like a plague, ive seen people putting a 650w PSU in a system with an onboard gpu, mkay.

Hey there, maybe anyone has an idea whats going wrong on my end.

I recently upgraded to an ATi 4770, and ofc wanted the card to crunch right away. So I went through all the FAQs on how to get started, which driver versions, dll renames etc.

However, I cant get MW to run, better say: it runs, but withhin 5 to max 20 seconds in the Workunit, i get a driver crash (screen hangs, monitor turns black, then goes up again, WU stops crunching)

I am however running Collatz without any problems since minute 1, so I cant be doing everything wrong.

things ive done/tried:

- dlls are renamed correctly
- BOINC does find my card correctly

08.10.2009 14:51:48 ATI GPU 0: RV770 (CAL version 1.4.368, 512MB, 960GFLOPS)

- Driver versions ive tested are 9.7, 9.8 and 9.9, 8.12 is not possible to install, card is too new. all the 9.x versions worked with collatz
- several BOINC versions, starting with 6.6.36 now using 6.10.4 since about 10 days. Same here, no client turned down collatz, but no sucess with mw.
- Ive tested the 0.19g and 0.20 optimized, crash stayed the same.
- I tried running only 1 WU at a time, still it kept crashing

I would appreciate any help or suggestions.
16) Message boards : Number crunching : New faster application? (Message 8657)
Posted 19 Jan 2009 by Sailor
Post:

I don't understand what you are saying. Should a faster processing (on GPU or CPU) get more credit or not?


Yes, my point was that a faster processor ofc should get more credits.


I'm not comparing the value of science either. How can I? My only point is that more work should give more credit, which is not the case in MW currently.


but more work IS getting more credit, the stock application doesnt get you 108 credits per hour.


About that stupid number, credit, I like it (that's me). I like looking at what I've done over the years processing for scientific projects. Plus, it's fun to play with this number and compare to countries, teams, people, computer technology over time, programming evolution over time etc. It's a good pastime. Gives me a better understanding of the world around me. But if it's capped or otherwise manipulated...


Well I do look at my stats aswell, but ill have to say I look at them from a different view. You say, the numbers tell the efford in science you did, but do they really? I mean I look at my numbers and I see MW now has caught QMC, but Ive spend much more processing time in QMC then in MW. So much for the comparison. I pretty much use credit to determine, in which project my CPU is efficient. Examples are : in Rosetta my CPU performs very poorly, the small L2 cache prevents better numbers, while Intels f.e. e8x00 series perform outstanding. So ive withdrawn from that project, not because I was looking for more credits, but because I think, my time can be spend better elsewhere - I think thats what credits are good for. In other projects you can tell from other things but credits, but Rosetta is one of those, where you can only tell from credits.

About the capped credits: I mean you are making 108 credits per hour and you talk about capped credits? And even pretty old CPUs getting these numbers. Show me any project that is even close to those numbers.

I wonder what seti is going to do now with their cuda app. Will they cap it?


What has a GPU to do with a CPU ? Its like saying a 3 GHz Quad core shouldnt be alowed to get more credits then a P II...

And it doesnt matter how much a project improves over the time, and certainly not compared to other project. How you gonna compare or value the science output from 2 totaly different projects? exactly, you cant.

And if MW stock app gets update to a new, faster level, admins might lower the credits again, like they did in the past, then youll be even far away from the numbers you are pulling now - so what? Im happy that I can run WUs so much faster now, and help the project getting to their goals a lot faster. Why dont see it this way? Its much more rewarding then pressing F5 on a statspage every 10mins looking how a stupid number keeps increasing.
