I had a tiny old Nvidia for a while. I think it was one of these, but the PCI (not express) version:



It refused to run any project except Seti, everything else was too complicated for it. It eventually stopped working through fatigue.

I run everything around 70C. I set fans to run 0% at 50C to 100% at 70C, but they often go past that to 80C. Keeping it under 70 would be impossible without water cooling or a very cold room. I run them in the garage and there are tropical parrots in there, so I aim for 20C ambient, with limits of 15-25.

I'm currently (stupidly) trying to rescue an old quad core machine. I replaced the motherboard when it refused to boot, which made it work but often at 1/15th speed. I thought it had bad voltage to the CPU, so I replaced the PSU which didn't help, then got another motherboard for it. That one refused to work at all because I'd managed to buy one which only took 4x1GB sticks, not the 4x2GB I had. So I bought more memory, and it still failed to start. So I bought a new CPU. When I get round to fitting that, I'll end up with enough stuff for probably two computers and some spare parts! Strangely the motherboards will sell on Ebay for the same price when they're broken.

Perhaps I could increase the cache next time I see waiting for validation piling up.

When I see the validation queue starting to pile up this is when I will start contributing in clearing any _1 or higher numbers before processing any _0 tasks. I haven't seen a pileup in quite some time

Doesn't that queue mean the validator is crashed, which means you won't make a difference doing that.

Hellow Link , Did it die or did you give up on it ?

I replaced it with the GTX 275 to crunch Milkyway again, it probably could run for a decade or two more, it had a custom cooler from PowerColor, which kept it at around 52°C when crunching, even with the fan @7V, so no thermal stress at all.

ps = thanks for the app.info had to modify it and use it to get the 1.3 app to work on XP32

Glad to know it was useful for someone. :-)

That is the `problem` of having a room full of parts ,
every now and then they add up to "if I put that bit and that lot in that case if should work"
so long as I buy that bit from ebay . . . .
it`s a never ending story of not wanting to chuck stuff out until its dead :-)
And the amount of "dead" or "For parts only" that sell on ebay is incredible .

LOL. Yeah, sounds familiar. :D

I believe processing numbers _2 and higher helps clear the backlog. It doesn't necessarily mean the validator is crashed it just means it's struggling to keep up with demand. In the past I believe this has been partly to do with the fact the ready to send queue has been so large. I believe admins had an idea how to fix it and it would appear that has worked

I just bought two "for parts only" 1600W UPSs, with decent batteries in them (I tested them and they were 100%). The two together went for a lot less than one new one. And they work perfectly! Nothing wrong apart form a couple of dents! The seller clearly didn't have a clue, he said he couldn't get them to turn on! I'm putting both sets of batteries together and giving one to my parents so they get hours of TV in a powercut, and adding mine to my array of caravan batteries.

You have a point, once you clear off ones that match with others, there's less in the database for the poor server to work out. Just don't cancel the lower numbered ones or it has to resend them.

Yes of course I process all tasks. If I didn't I eventually wouldn't be able to receive any tasks as I would be deemed an "unreliable host" and would not get any of the higher numbered results sent to me in the 1st place or worst case scenario not be able to receive "any work" whatsoever because I have abandoned too many tasks

Lots of downtime on Milkyway recently, most of it when my computer is on, so back to Moo! crunching.

My computers never sleep, poor things.

I've got 9 graphics cards doing world community grid just now. Their tasks are double precision too, I'm ploughing through them with a bunch of old 280X cards. Their upload server can't keep up with my returns :-)

Doesn't Milkyway have stuff available 99% of the time?

Actually, Milkyway is best for the old AMDs or the pro cards, with a more sensible DP ratio than Nvidias. I run it on 12 Tahiti cards, 4000 GFlop SP, 1000 GFlop DP.

I guess you're running out of things to do with it. I'm surprised such an old card is still going, does it run 24/7?

I have an Nvidia Quadro K600 (981MB) gpu on it and it crunches Moo just fine. I can't put a more powerful gpu in it because the PSU is too small and it's one of those case length ones that HP and Dell used. They are WAAAY too expensive to replace and there's no room for an external psu. The pc also has 2 quad core Xeon cpu's in there as well, so 16 cpu cores.

ROTFL!!! My garage resembles that remark!!!

How can you not just sit a PSU on top of it for the GPU?

I use a couple of very powerful 2.6kW power supplies for all the GPUs, and a couple of 1.3kW and a 1kW. They're connected in parallel and power all the computers' GPUs. The 2.6kW ones were £12 each! Old HP Blade server supplies. 200A each at 12V. Very long and thin. 2.5 foot long, a few inches tall and a few inches wide.

My HP and Dell pc's are model Z600 and T5500 pc's I've only seen direct replacements not upgraded psu's that have more wattage in them.

Because my pc's are on wire shelves like this

Probably you even can't use anything else than the original PSUs, the HP mainboard seems to have non-standard 18-pin connector according to the pictures I see on Google and Dell is known to use own wiring on standard ATX connectors, so you'll burn the mainboard and/or the PSU if you use anyhing else then the original PSU.

I'd never buy a desktop computer not build out of standard parts, when anything fails, it's just scrap as replacement parts are usually very expensive for such systems or not available at all once they run out of support. Well, I'd never buy a prebuild destop computer, but that's another thing.

Nonsense, you can find the pinout easily, especially if you have a working PSU of that type. Or just buy some 2nd hand PSUs for that model. I got Dell xeon server PSUs for £25. When they're not powerful enough, you don't need a bigger compatible one, you just need more on the 12V line. Just get any old PSU and use it in addition. You don't even need to wire them together, just give the GPUs 12V from the other supply.

Because my pc's are on wire shelves like this

That's a very low resolution image, but it looks like you could just shuffle them around a bit and put the PSUs next to them. The ones on the floor on the left you just sit the PSU on top.

By the way metal shelving is a bad idea, you're asking for shorts. I use wood.

Works only with PSUs, that don't require significant load on 5V to keep the 12V line at the right voltage. Some won't even turn on without something @5V.

I understand why you are worried about shorts, but in general, as computer cases are made of metal, there's nothing wrong about putting them on metal shelves. Server racks aren't made of wood either and nobody worries about shorts there eiter.
