-stil im aint able to understand how ppl with just a GTX260 can have 10k RAC then- :D

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.

Ok, seems u guys where right im at 16k now! The last guy: Yea my gtx 260 is running on core speed 700 and the gtx285 at core speed of 730 :) so i hope i can come beneath the 20k RAC someday =)

17,5k now and my GTX260 is doin a very nice job at 11k RAC, but worries me is my GTX285 how can she have such a low RAC !?!?! :|

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...

Ah ye, i changed my system from XP to Vista where the GTX285 is on and them any aborted Wus was when i tryd out SETI :|

BUt look at the cpu times, the gtx260 takes arround 2k~ each Wu and my gtx 285 4-5k+~ what the hell?

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?

My clocks are:

Core clock: 730

Shader clock: 1548

Memory clock: 1404

on the GTX285 and im using the driver "182.08_geforce_winvista_64bit_international_whql"

on Boinc 6.5.0

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.

well EVGA Precision tool aint showing it in x2 so yea its 2806

Comeone guys, there must be a solution on this, i even renewed my mainboard drivers! Still same problem my GTX285 gets on 1hr 5% on WU process and my gtx 260 is doin 10 in not even 20 minutes! :(

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.

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.
