I have just tried V6 (I have had to register at "Opt. Seti...") on both PCs. They now DON'T reset BUT:

The first one only get "Calc. Error" in each unit it tries to crunch.

The second one is crunching a unit, but this unit will take HOURS to be finished. Units similar to this one were taking about 10 minutes to be crunched with the original SETI program.

I have decided to abandone SETI until they get rid of this error.

I started using CUDA. The first iteration of the software worked well for me. There were few, if any, problems.

BOINC updated the software. Since then, performance has been abysmal. There has been one "Computation error" after another. The rate on recently download work units is approaching 30%. AP units work fine. There is no problem.

The system checks out, and it passes every diagnostic.

Does anyone have ideas, other than rants, about the problem and a suggested solution.

I have no qualms about donating time and expenses to SETI, but I'd prefer not to waste either, and as a scientist, I prefer not to submit possibly tainted data.

Thanks in advance for all ideas.

Unless you're a programmer, and a pretty specialised sort of programmer at that, I'm afraid there's not a great deal you can do except wait until the current programmers finally get to the bottom of all the problems we're all experiencing. They're working on it: another Beta application (the second this week, already) has been released on the Beta project within the last hour-and-a-half.

If you, or anybody else reading this post, has any experience of beta testing software - reading and following instructions: spotting errors: writing clear, concise reports of the problems encountered and the circumstances in which they happened: trying to work round problems inaginatively and reporting the results - then by all means join Beta and help make it work better for yourself and everyone else.

Oh, and bring your magic wand with you - it might come in useful!

How will you be able to tell if they did, when you have abandoned Seti?

Must be me, I don't get it. What is it with people who are throwing tantrums over this when all they have to do is either move back to an older BOINC version, or (temporarily) disable the GPU option in their preferences and crunch with their CPUs only again?

It's not as if the only option you have is to run Seti through the GPU.

I only wanto to run SETI with GPU. I will do what I'm doing since the first time I used GPU on SETI, try it once a week o less (aprox.). If it crashes, I'll stop and try a week later and so. This has been my second trial (I have already left aside seti.cuda because it crashed my PCs)... I think that they have to do tests at Seti.beta, not this project.

I noticed several posts in this thread about hardware failures. I hate to plug a particular vendor in a forum, but since I knew I was going to push my cards hard with CUDA, that's one of the main reasons I went with the vendor I chose. They give a lifetime warranty on their cards, even if you overclock them (which I don't). It's a nice peace of mind since I can't afford to replace expensive components often. I wish the other vendors would do that as well. Everyone thinks the same model card is the same from each company other than appearance and perhaps some default settings. But service and warranty matters too if you have a problem. Shop carefully. I'd be po'd if I spend $400 on a board only to find out they won't replace it when it overheats and dies, and since they market these newer cards as CUDA capable, that shouldn't be considered an abuse, though some companies do say that against warranty claims.
