Hiho, well im not that experienced yet in all this stuff, but from what I saw and heard 12k RAC for thoose 2 Cards is way to low !?!? What could be the reason? I had thoose 12k rac~ after a week of 24/7 crunching!

The GTX 285 (also OC'd) is running on a Q9300 @ 3GHZ on WinXP Pro 32bit

The GTX260 (216 cores) is running on a standart E6300 on WinXP Pro 32 bits..

Please give me any hints how to optimize that!

Thanks in advance =)

I don't think it's too low if you're talking about individual cards. If both combined give you 12k RAC then I guess the number hasn't settled in yet.
Edit: you could take a look at your daily update numbers here.

RAC moves very slowly. I have not done work for SaH in over two months ... still have RAC over 1 ...

You can look at the stat sites and they post data that can give you a better view of the instantaneous daily production. Or you can manually look in your pages here to see how many tasks per day the cards are doing.

Had a look - all your results are working great - the cards are crunching nicely, and you are being credited for the work done. Just check every now and then that you are crunching the number of WUs you expect to at any one time, in case some did not load correctly, and in fact you have an idle core somewhere.

Paul hit the nail on its head - RAC is a variable beast in the way its calculated, dont get hung up about its actual daily value, just use it in a relative sense to get the feel of a trend in your results.

Get into the habit of looking at the actual daily results - not averaged out (RAC) results - feeding through to the Stats.

As long as the actual daily totals are feeding through, and your work is being reported in BOINCStats, all is well.

Actually it is just one GTX280 ...

But, the two GTX295s may also play a part ... :)

Well, don't want to be rude.. but had you bothered to take a look at the daily update numbers of your account on the website which I linked to, you'd have seen that yesterday you earned 23551 credits and today you're up for 22310 credits. That should give you some hint ;)

Today you are at 13.5k RAC, whereas 2 days ago you were at 13.0k. Yes, you are doing something wrong: you are not giving it the time it needs to stabilize..

You shouldn't have pending credits in GPU-Grid at all, as the credits are awarded almost instantaneously upon result report. But even if you have pending credits this is totally unrelated to RAC. Pending are the credits which you should get, but which have not been granted yet (e.g. still waiting for a wingman), whereas RAC is the Recent Average Credit.

Well, overclocking improves speed, as long as you don't produce errors. In case of errors you obviously don't get credits.

I get the feeling you are still hanging onto RAC as the "ultimate" statistic and basing all judgements on that, wanting instant - or near instant RAC change. RAC is purely - and only - an average of past credits spread over a large number of days. It will therefore climb slowly as an improvement takes place - or the initial startup period on a project plays through. It eventually flatten out not increasing further, assuming no improvements are made to the rig. The whole process of RAC climbing and stabilising can take 2-4 weeks depending on what you are crunching.

Your actual results are good - they are in the range 20,000 to 25,000 credits, thats fine, all good to go, the cards are doing well. Be careful not to tweek yourself to death in the meantime motivated by an RAC number that only changes slowly and is purely a statistic indicating a long term trend.

The actual daily results are where its at, and is the real indication of the card's performance - and the latter at present is good :)

If your core 216 GTX260 is on and crunching 24/7 for 30 days it should come close to 10K, but may need a little overclock to get there.

The 285 should get there easily.

However, RAC is an average over 30 days. You need to have them on and crunching 24/7 for 30 days to get your RAC to climb that high. Total Credit is a better measure of how much work you are doing, as other posters have said.

Hmm btw, how does Overcloking affect with GPUGrid is it good or not good to overclock my card? cuz that might be the reason then cuz my gtx285 is overclocked... could this be ?


Overclocking is very good for performance, yes. If you are running windows, EVGA Precision makes OC'ing the GTX cards very easy. With a few clicks of the mouse you can go from 576MHz to 700MHz+ (one of my teammates had his at 740MHz if I remember correctly). It just takes some time to get things stable so the system and the work units don't crash.

Maybe because of the many WUs aborted by user? Maybe because you only finished 16 tasks successfully on this computer since March 20th `til now?
And unless you don't have two computers with a GTX285, merging the two hosts shown with the GTX285 could also help... ;-)

Like many people told you before - Recent Average Credit takes some time to rise. With only a few returened results you won't see a hughe increase...

The cpu times don't tell you much at GPU-Grid. To see the runtimes you ahve to look into the individual results. However, doing a quick check I see that your 285 indeed seems to be too slow (260 & 285 on rather similar WUs). The shader clock of your 285 is normal, are any of the other clocks off? Which driver?

Software versions should be fine as well as core and shader speed, but what's up with that memory clock? 1400 MHz is strange: it's too high for the real clock of current GDDR3 modules, which implies that 1400 is the effective DDR-clock, i.e. the clock multiplied by 2. That would mean your GPU memory runs at 702 MHz, which is way underclocked and would cost you performance.

Guys, I find this weird. I stopped using gpugrid for about 2 months. Yesterday I came back to do some number crushing and to my surprise... it takes me about 12 hours just to finish one task. Before it would take me, more or less, 3 hours.

I have a gtx 260 (normal one) and windows xp. I have tried diferent boinc versions and sitll getting the same results.

P.s. Nothing changed in my pc except the graphics drivers (the latest nvidia ones).

I also have a GTX260 since the very beginning of the first alpha tests for GPUGRID (and it is running with the same clock speed like yours), but I don't remember we ever had tasks that would only take about 3 hours on that card... Are you really sure about that?

But yes, we have a few different WU types now, and about 12 hours per task on the GTX 260 seems ok...

Ok, than I don't have anything to worry about.

Yes, Usually it would give me 2 to 3 thousand credits for each work unit and it would take an average of 3 hours.

Example: from 90 cpu time to 300 cpu time.

Right now it has been from 759.03 up to 1,166.92 cpu time.

Because I do more seti, I didnt spend to much time with gpugrid. 99% of the score I have right was done usually when Seti was down and that wasn't for long, lol.

I also have a GTX260 since the very beginning of the first alpha tests for GPUGRID (and it is running with the same clock speed like yours), but I don't remember we ever had tasks that would only take about 3 hours on that card... Are you really sure about that?

Several people have tried to convince you to stop quoting RAC, and therefore possibly missed your real concern.

Please look at Your Free-DC stats

RAC adjusts slowly. Look at your last two days results and "average" which is a 7 day linear average. RAC will *EVENTUALLY* get close to the 7 day linear average with steady work.

However, why your 285 is doing half the work of the 260 is quite simply that it is getting far too many errors. It could be the drivers, it could be your machine (it does bench a bit low for a 9300). Assuming you only have two gpu's and downgraded the machine with the 285 from xp to vista on march 19, the card was doing about the same under xp, pulling down 10k when it did work. Output on the machine under both XP and Vista is less consistent than I would expect, and lacking behind what the 260 is doing. Looking at the machine in your profile, I see it is getting a WHOLE HEAP AND BUNCH OF ERRORS! That suggests you overclocked it too much, your case does not have enough cooling or your PSU is not up to snuff.

Quoting RAC is a red flag to people that gives them a reason not to help you.

edit: looked at your machines, saw the errors on your 285 and modified my post.
