TPU's F@H Team

[mstenholm]

Hello fellow folders! I would like to announce the "World CEP2 Challenge" that our WCG team is organising. If any of you feel like transferring some resources over to WCG, please do so for the period of 6-14 October. I promise I will make sure I donate as much GPU resources to F@H as I can in order to compensate.

Here is the link to the thread on TPU: http://www.techpowerup.com/forums/showthread.php?t=191430

I doubt that you will find support from many of our 13 active folders...we are all waiting for winter. The weather forecast did however say that Denmark will have night temperatures close to zero Celsius so I fired up a i7 970 with a 7970 (folding) to keep my workshop warm.

It is common for us to let each other know of the challenges we have and sometimes we transfer a bit of our resources. It is not mandatory, and for some it may indeed still be too hot (or on the southern hemisphere, heat is coming). It does not hurt asking though. We will beat France and Ukraine again anyway.

Nice
I only have my Tahiti cards and a 560TI448 going, but I can still do what I can w/ my GPUs

 

[Peter1986C]

Do you guys get any GPU work for your cards?

Yes, my GPUs are all folding away right now

I get this in the logs:

Looks like someone fired up some Magny-cours!

Affirmative. Couldn't get WCG going, so I fired up F@H. I keep getting a "requires installation of untrusted packages" error during installation from the software center. Still running Ubuntu 10.10 on these rigs. Need to get WCG installed for the challenge.

 

[Peter1986C]

I would try it with those versions of BOINC from the BOINC site instead of the package manager.

F@H Core16 WU supply ends within 2 weeks. Note: AMD 5xxx cards reportedly perform less on F@H core 17.

I did around 50 K on a 7970 running a core17 job and then I got a different (old?) WU and got around 2.5 K. Sorry not at +35 cents/kWh when I don't need the heat. I will back with my AMDs when the snow hit Denmark.

 

[Peter1986C]

It was just a FYI.
And yeah a 7970 has a vastly bigger impact than my 6670 on the bills.

Folding rig is out of commission for a while.

Any idea what change this will mean for those of us with Radeon 7xxx cards?

You don't want core_16. You want core_17. Currently you have to have your slot set to advanced to get them.

OK, I'm already getting the bonus point WUs, so I'm good to go then, right?

Am I seeing it right that the PSU connector failed, not the motherboard connector?

Both are equally scorched. I'm waiting on a new power supply before I'll know if the motherboard is dead or not. I do know folding with two GTX470s won't be happening again though.

 

[[Ion]]

I can't even imagine folding with two GTX470s...oh god the noise and heat

 

[Jstn7477]

That happened with my ASRock A770DE+ but on the 8 pin connector if I recall. I was only running a 5770 and a 6670 but had a 955BE overclocked to 3.8GHz which of course burned up the board after a couple months of maximum system load.

Well, Norton found out what two GTX 580s did a while back. (check Buck's forum signature)

 

[newtekie1]

Yeah, I was folding on them 24/7 but the noise got to be too much, the heat I could deal with. So I had them set to only fold when the computer was idle, which is when I'm away from my desk and the noise won't bother me.

This failure is really due to a poor design by ASUS. Any motherboard with more than 1 PCI-E x16 slot should really have an auxiliary power connector to provide extra power to the PCI-E slots. If you think about it each slot is supposed to provide 75w of power. The 24-Pin only has 2 12v wires, which is fine for one slot. However, if you use two or more slots then those two 12v wires quickly get overloaded. The wire on the PSU, an HX850 by the way, got so hot they turned from yellow to a brownish-yellow.

 

[[Ion]]

The noise is insane--that and the heat is just too much for my dorm room, so unfortunately they sit idle until it gets legitimately cold outside--then I'll see about firing them back up
But yes, an auxiliary power connector does seem indicated...

 

[Athlonite]

Ion think about WCing them if noise and heat are that bad

newtekie1 good luck I hope it didn't cook the mobo

Given that they're in a system that is used exclusively for DC stuff, I don't consider it worth the cost. A WC loop for that system would be pretty expensive, and I could outright sell & replace them for probably less.

Water cooling would help with the noise, but the heat would still be the same.
