Yeah, have to agree about the "kiss of death" regarding bulging capacitors on motherboards. Unlikely too that he will be able to see small ripple voltages with just a simple DVM unless he's ordered a really expensive one which the bulging capacitor almost certainly is producing. If I remember an earlier post correctly, the motherboard is a 1999 Dell vintage. That puts in right at the beginning of the bad capacitor plague caused by the bad stolen industrial espionage electrolyte recipe.

The computer is an HP 2009 vintage instead. You may be thinking of someone else's computer.

Any other ideas on what to try after that?

I go back to power. If you have access to a voltmeter, look at your 12v (yellow). Especially see what happens when you start up and shut down BOINC.

Looks like I'll need to know what the other wires to the Molex connectors are also. Two black and one red on some, black, brown, and an empty space on others.

I've noticed that one of the electrolytic capacitors on the motherboard may be bulging - the top is rounded on that one, but flat on all the others. Not something I can still fix without help, if that's what it is.

. . On the Molex connector the black wires are ground and the red is +5V while the Yellow is +12 (unless I have misremembered that part :{ ) but the connectors are keyed to avoid issues, that is why they only go in one way. Usually a brown wire is only substituted for a red wire (brown&blue replace red&black respectively due to colour blindness confusion) so I would expect to have brown black black yellow. I don't know why a molex would only have +5V and no +12V. If the molex connectors feeding the adapter for the GPU do not have yellow wires then you have a problem because the purpose of external PCIe power connectors is to provide more power at +12v not +5V.

The yellow wires were already described above, so I only mentioned the other wires. The brown wires were substituted for one of the blacks, but only on connectors where the position for the red wire was empty. No missing yellow wires.

. . The sad thing is modern electrolytics tend to last more than 6 or 7 yeats on average, I think the mean life for such copmponents is around 12 years these days. But there are always some that fall out of the main stream.

PS, if it is a small enough value/voltage rating maybe a nice tag tantalum could replace it :) and if it's legs are long enough snip them off and solder the new tag cap to the stubs :)

. . OK that makes more sense, but strange using brown wire for ground connection, maybe they had access to lots of brown wire cheaply :).

. . they sometimes only run one black and common it across the two centre pins. But that is being cheap and nasty. It mean a lot of current on the one wire.

. . But I think you may have found your problem with the suspect capacitor. Di you have any luck getting drivers to work with the GT450?

Have you checked HP for an updated MB BIOS?

Some PS designs like to keep the ground busses separated except at a single common point, so will color code them differently.

leaving this current thread for a sec ...

I've been running SoC nvidia Lunatics v0.45 for a while and have had good luck.I was looking at some results and saw this line:

OpenCL Platform Name: AMD Accelerated Parallel Processing

I had a amd card back 5 years ago and so decided to remove the amd software ... oops ... started getting errors ... no opencl software !

I reinstalled the current nvidia video driver and all seems well .

1) so I was running my Nvidia 770 opencl with 4 year old AMD implementation??!!
2) should I expect any differances now that I'm running current Nvidia??

(strange world when computer open software has interoperability!)

Edit:
First soft observation is on 3 Guppies that "look alike" the old AMD driver run at 16:54 and new nvidia driver ran at 20:18 ..as I said ... soft observations)

. . Hi Richard,

. . At the risk of actually being on topic, is there any news of either RC status for r3528/v8.19 or a beta release with it?

. . Just thought I would ask :)

I built one, and literally ten minutes after I'd finished, Raistmer reported a potential problem with r3528: Beta message 59633.

Waiting until he replies to your question in the support thread.

The kitties have to ask..............
Are we getting closer to a .45 installer?
Or are we forever mired in the muck of SOG?

. . I asked that earlier (but the message is lost in the plethora of other messages) and Richard referred me to Raistmer, who answered me in the V8.12 GPU apps support thread. He is waiting on Eric and hopes to know by about Tuesday.

. . I'll be waiting.

Stephen

Probably we should move this to its own thread, Richard has been very tolerant and not pinged us for being off topic but it has gone on much longer than I ever expected. Would you like me to start a thread for it or would one of you guys like to do it?

Yes, please do.
I am more anxious to see news related to working the remaining bugs out of the SOG app and the proximity of the release of the .45 installer.

"Time is simply the mechanism that keeps everything from happening all at once."

. . Hey Raistmer,

. . Have you heard from Eric about the fate of r3528/v8.19 yet?

Eric was/is at a scientific conference.

No timetable on how long the conference was scheduled for.

. . Hi Zalster,

. . I thought he might have been back by now :(. But I am sure even if he was that he has a lot of other things on his plate too.

Stephen

.

Actually, If I were him I'd take a vacation around the conference. Before and after that way he can relax some. Because we all know, no one really relaxes during the conference, lol

Yeah I left an email message for him regarding choices of path with Petri's optimisations as well. I'm not expecting responses until some political and scientific chaos dies down :)

. . Hello everyone,

. . I apologise for this off topic question but, when I access the Seti HQ option to look up "My Computers" the data is wrong and has not changed in about 24 hours. Has anyone else noticed this behaviour and does anyone know if something can be done about it??
