My gtx570 has developed some wierd fault and its gone for repair, black screen no output.

Got a gtx260 off mega and it worked for 2 days and then died and all that will do is bsod, and i bought a radeon hd5830 and it was pants and so slow i have flogged it.

So no work from me untill maybe monday when msi have fixed my card
and i am getting a hd5870 but from amazon on tuesday so i wont see that untill thursday or friday but i will be back 8)

Bad luck! I have been watching your stats with interest as you have been doing very well. I even thought about buying the same graphics card you got but will now re-consider.

Hope you get things sorted soon. Your team needs YOU :salute:

They have replaced my twin frozr ii card with the new twin frozr iii.

Pay day tuesday then my hd5870 is being ordered, is that what you have gary and if so how long for it to do a dnetc unit?

That hd5830 took 45+ minutes wasnt impressed with that, the gtx570 will do one in 16 minutes but with it being cuda it gets rag all credit so its not worth doing as it favours the ati jobbies.

Great they supplied you with a new card, just donâ€™t let them know you run it 24/7!

I have a ATI 5970 which knocks out a DNTEC work unit in around 19 minutes, though some seem to take longer and complete around the 24 minute mark. When running 24/7 it can complete around 500,000 or a little over credits in DNETC or MOO! Wrapper. I donâ€™t run the card over clocked to be honest it is puts out a lot of heat at stock speeds without overclocking it and making matters worse.

I have heard that DNETC pays more in credits but in the past I have run out of work units so run both ensuring a steady stream of units.

My next card will probably be a Nvidia 580 or 590 I just have not taken the plunge yet and gone out and bought one. Not really sure I can justify two desk top systems when I have just purchased a Asus laptop a couple of weeks ago and itâ€™s only me who will be using them. I would also need a new motherboard, processor etc - basically a whole new system which would be a major expense.

The 5970 is a dual 5870 isnt it, so does it knock out 2 wu's at a time then, like the gtx 590 does?

The 5870 should do 1 in 19 minutes then, that will do.

Is moo the same times as its basically just the same thing as dnetc isnt it?

Oh yes i did tell them i was running prime grid and all he said was whats your psu 12v rail output so he looked as i got it from there, then suggested me getting a better one with dual rail 12v so i bought a new psu for Â£51, wasnt bothered about me running it at all.

The frozr iii is running about 8 c lower than the frozr ii but its a custom pcb with a better fan design and so called Military class components, they know there made to be over clocked its got triple voltage adjustment for gods sake they know what most ppl do with them.

Does a prime grid wu @ 9:45 which is some going.

Sorry to hear the 260 didn't live long Rob.

Your spate of video card failures does suggest that some other bits of your system might be dodgy. A PSU upgrade is never a bad idea.

As regards blank screen faults I've had that intermittently with both my 580 & my 590 cards. The good news is that both carried on crunching boinc regardless of the lack of video output

and everytime a driver reinstall restores normal service.

CUDA capable cards always mention the fact in their specs and ATI cards generally boast of their crunching - albeit Folding@Home rather than Boinc- capability so there is no reason that Boincing should affect your warrenty.

As regards Moo vs DNETC, I've not done Moo since DNETC came back online, but at that time Moo was only half as generous.

Anyway, congrats on your tenacity Rob: remember there are no such things as hardware problems, just upgrade opportunities!

On MOO! and DNETC both GPUS work on one WU at the same time. On Milkyway and Collantz each GPU unit works on a separate WU so two WU are processed at the same time.

For an indication of graphics card hierarchy Google Toms Hardware a hardware review site. It publishes a rough and ready graphics card hierarchy chart amongst other things or look here

I dont need that table but thanks for that maybe it will help some, im obsessed with graphics cards but maybe more nvidia than ati, i have always been a geforce fan boy.

I had a geforce 256 back in 1999 and compared to the voodoo cards around at the time it was the best thing by far.

I hope that this damm hd5870 is worth it as its Â£200+ i will be way hissed if it dosent do a unit in 20 mins or less

I dont think it will. The 5970 is a dual card and more powerfull. Looking at some of the latest WU it has processed many of these are over 20 minutes. If you were to go for the 6970 it probably will not achieve sub 20 minutes. To get this I think you will need the 6990. When I purchased the 5970 less than a year ago it was close to the Â£600 mark if my memory serves me correctly.

Perhaps you need the chart after all

Can anyone else give more accurate performance stats for the 5870 running DNETC?

Good luck and let me know how it all works out.

That chart gives you game performance data by the look of it, your 5970 is taking 20 minutes ish for 2 gpu's to do 1 work unit and getting 6500 ish per wu, thats poor times but exceptional return in credit.

My TFIII does them in under 10 minutes or just over 10:20 ish and gets just over 800 credit per wu.

Which goes to show if you go off that chart you would be expecting similar reward but it does not work like that, why do some projects reward you better for a worse performing gpu?

The credit should tally with gpu performance and by the look of it it does not, i have no doubt in gaming benchmarks the 6970 will toast my 570 but for boinc its performance is way worse, i just dont get whats in the thinking of the project owners at all.

I dont know whether its worth my while going for an ati card now as if i spend Â£250+ on a card that takes 40 minutes to do anything except milky way and collatz which both reward poor credit, i wont be happy.

I am thinking if not to just get a gtx560ti and run 2 comps on just primegrid, but i want some of that sweet credit from moo and dnetc, im going to have to think about this

Willie what is your best ati card, i can see one is getting 31ish minutes.

ATI Cards? On DNETC I take it?

My best machine has a HD 5850 Card in it which returns a unit, worth 6.6K in 31-32 minutes. ie up to 300K per day. 8)

It's way behind the top flight NVidias but still steady enough work.

Obviously nvidia's cuda is better suited for the job and amd in that case need to optimize their open cl or the project compilers need to.

I monitored gpu usage on dnetc and the ati card was running @ around 75% but up and down then i tried the TFIII and it was up @ 99% constant, there tells a tale about programming and utilization, that or the advantages of more memory.

Anyway from what im getting here is that the 5830 (1120 cores) did a dnetc wu in around 45 mins average then your 5850 is knocking them out in around 30/31 minutes (1440 cores) roughly 15 minutes less so a 1600 core 5870 should do them in about what 7 1/2 mins less (as there is only 160 cores more than the 5850, the 5850 has 320 more than the 5830) so 22 1/2 mins to 23 1/2 mins

But what i dont get is why a 5970 only does one in 20 mins ish when its a dual core

and its double the 5870

Anyway im going for a 5870 coz a 5970 is wayyy too dear for not that much gain...... l8rz
