Hi all

Anyone with NVidia cards would do well to consider moving them over to use the cuda app on Primegrid.
My GTX295 running collatz got between 40-70k a day but running primegrid it's getting 80k every day.
My 2 GTX260s were claiming about 24k and now 34k on primegrid.

It's a standard app, so no messing about with app_info or anything.
It certainly works well on my cards, I don't know how it will perform on other cards though

Nice find John!

I knew PG where doing some testing with CUDA a little while ago but i never found out if they put it into full production. Unfortunately it probably doesn't support my now defunct 8800GT  :lol:

That is quite an amazing about of points from the GTX though  :shock: Nice find!

I had never used my gpu card with PG

Card is a 8800GT

Now running Proth Prime Search (Sieve) v1.30 (cuda23)

Retuning 134.87 for 9 mins work

See how it goes for 24 hours.

As above + 9800GT. Seems to work out at 21,000 per 24 hours per GPU.

Pity this PC is only on for around 6 hours a day - could do some damage then!

I've noticed though that the GPUs are running hot at up to 85 degrees and there is sometimes a screen lag due to resources being used. May have to 'snooze GPU' occasionally - we'll see.

Oooh it works on your 8800GT?? Might stick mine in and have a go next weekend  :D

Also what applications do you run John?

Mine has settled out at 60 degrees and NO screen lag at all  :)

I'm running the Proth Prime Search on the GPUs and only RCN on the CPUs

I should point out that the GPU app also uses 0.73 of a CPU
And as others have noted, there is considerable screen lag at times, even on my GTX295

Also works on NVIDIA 8800GT under linux (fedora .
First 3 w/u took 8mins each for 134.87 credits.

Hiya This is a great project for both my low end Nvidia cards
NVIDIA GeForce GT 220 (1023MB) driver: 26099 =
1,269.34 sec's for 134.87 credits .. Proth Prime Search (Sieve) v1.30 (cuda23)
NVIDIA GeForce GT 240 (1023MB) driver: 26063=
608.59 sec's  for 134.87 credits Proth Prime Search (Sieve) v1.30 (cuda23)
They both lag Gt220 uses 0.38 cpu .GT240 uses 0.51 cpu

All the x64 apps give much better credits than the 32 bit jobs on the cpu's

Only down side ...Was up to 10th place and got run over by John's 2Mill in a week  

it looks like the party's over for PPS on NVidia cards, for the time being at least.
See this primegrid forum post.

Was good while it lasted

It's all go again and even better credits than before :thumbup:


PS
can someone fix the broken post above please, UBT - bobuks' I think on Sun 31-Oct-10, 18:35

Fixed

thanks Darren

 Gt 220 and Gt240 now giving me about 120k per day lolol  Hurry up santa i want more !

There's currently a very good deal on a GTX460 on overclockers
£120 for approx 350,000 credits a day running primegrid PPS
Only 12 left at time of writing

Ughhhhh.  :D  :shock:

I had one of those ( 1Gb ram + factory overclocked ) in my hands not long after release .. thinking it'd be a nice upgrade from a 9800 gtx + ..

Found out to my cost via 'Scan', that my mother board isn't modern enough, and these newer gen cards need newer chipset motherboards to recognise them.

The swines admitted it was a known issue, but still billed me restocking fee for my troubles grrr... so that was me down £23 and swearing to never purchase from Scan again ..

But yeah, the 460 is supposedly awesome  :D

???
I've not heard that before, do you know which chipset is required?

You should've mention it on here, I'm sure someone would've taken it off your hands

Bob would have been off his wheelchair in no time! lol!

I sense some text abuse via MSN coming shortly  :lol:  

Although it surprised me too that it wouldn't work? They might have meant it would not support PCI-E 2.0 bandwidths on the motherboard if yours is slightly older, however bandwidth doesn't make any of the projects go faster anyway as far as i can tell as most of it is loaded into it's high speed on board RAM? I could be wrong but that's what it sounds like.  :?

Well I kind of got trapped in the 'returns' system.. lesson learnt.

Not sure about compatibility Ben, surely the 9800gtx + isn't so far behind technology of the 460 !!

It wasn't so far behind the GTX260/275/280 etc but not sure about the 400 range  :?

What happened when you put it in the machine? Was there an error message etc?

Something along the lines of card not recognised, Scan tested it when returned and it was fine..  :?
