Arg, first 100+f temp day inside my apt today. Don't have ac, landlord wants 30 more for that... so I'll be
taking down my fermi for the summer soon. Just watching the weather, but when it gets hot here, it gets
hot. May get a few more days out of it...... Praying for Kepler manna......

 

[T-Bob]

Does this apply to the gpu @T-Bob is running as well? He turned in a bunch of jobs at over 87k each over the past few days!!!

That's my watercooled 780Ti. I just got my 7970 back online Friday night.

That's wrong. Can you buy a window AC unit?

I'm going to try and test today if I can get the GTX 465 and GTX 470 running simultaneously on my Q9550/Maximus II Formula rig. If so, I may switch the 3770K machine back to Windows and move the Tahiti Radeons on there and put away the ASUS A8N32-SLI which has a defective CMOS chip that dumps its RAM as soon as the system loses AC power. I'm tempted to try the Radeons in Linux, but those two cards are responsible for half of my PPD.

That's not a dead CMOS battery?

I've changed it and also probed the chip holder to make sure power is getting there as well. An ASUS NF4 board I bought from Mad Shot did the same thing until it died, and I have an ASRock board that saves settings when unplugged, but the RTC stalls.

@Jstn7477 , thanks for the instructions on how to get Nvidia GPU F@H working on Linux. I got it working yesterday. BTW, AMD F@H under Linux is supposed to work as well, (just set the client-type to advanced) and you don't have to do anything like the CUDA install.
@BUCK NASTY , I don't know about PPD under Linux, but my 660 Ti is showing in the client as pulling ~79K on a P9408 and that's without any OC. (that model of 660 Ti runs @ Nvidia's stock clocks, no factory OC) I'm still learning Linux, but what I could see from system monitor is that the client loaded one core to 100%, and under the list of processes, it shows a 12-17% load. I have that system in a poor case oops and am nervous about letting her rip on F@H and WCG at the same time. The GPU is running @ 71 degrees without an OC, but I never saw it out of the low 60's in my P280.

I might try AMD folding on Linux on my desktop, it has a single HD 7950 currently and has one 160GB drive with Ubuntu 14.04 on it.

 

[thebluebumblebee]

Oh, I did find that the CUDA install does install the 331 version of the drivers, which is a problem for me with my GK104 GPU. Simple to switch it back though.
I did not try to see if I could have installed it under 14.04 LTS. I'm liking Mint's interface better than Ubuntu's.

If at all like trying to get bitcoin mining going on linux, it was a pain. I had the hardest time getting open cl to work.

 

[Jstn7477]

The GTX 465 and GTX 470 seem to be working perfectly together on Linux, all I did was put in the 470, add a folding slot and bam, estimated 58K PPD and rising.

Difference is Amd. Amd drivers on linux are no where near the level of nvidea drivers. I am not saying don't try, but expect a challenge.

Yep, I have played around with AMD drivers since Steam was released on Linux, and back then NVIDIA cards seemed to work nearly flawlessly while my 7950 was getting the framerate of an IGP in Team Fortress 2. I haven't messed around with it in about a year, though.

 

[thebluebumblebee]

if I understand correctly it is possible right now to use an AMD GPU with Linux and the FAH core 17 ?

this is a very good news ! so should I use an AMD driver in particular ?

it must therefore be nothing except adjust the GPU slot on "client-type advanced" ?

Yes, that's what it looks like. AMD 14.4 drivers should work fine. Client-type advanced should pick them up once the current workunit finishes.

 

[manofthem]

As soon as my Internet gets back up, I'll be folding again. Not sure if you guys have Comcast, but around here they're all idiots that sure aren't too bright.

 

[Jstn7477]

For those who want to run AMD GPUs on Linux, I... suggest not trying to. Had to reinstall Mint 15 on my 3770K to get the cards working without the X server crashing, then install the drivers (which actually have an installer now, thank God, I used to have to use the .run file to make DEB packages and it was even worse). The drivers install fine, the cards seemed to work after reboot, so I installed the F@H stuff and the cards were folding, so I rebooted again, and the GUI is now unusable, parts of the taskbar appear but everything else aside from the desktop and its icons is invisible. Also, each F@H core literally uses half of the i7, not good when both cards use at most one thread combined in Windows.

 

[johnspack]

Have a window unit, he will charge me 30 more if I put it in. Will have to put it in for July... by August it can hit 100f outside, 120f inside.....
Yes, it can get hot in Canada!

 

[johnspack]

Cracked 100f in my apt again today, I hit finish on the last 13000 wu, god I hope it finishes. 480s should not be folded!!!!! See you all again when I get keplers.

 

[johnspack]

Well, we hit some freaky sub 20c weather here for a day or 2, so I'll try to squeak out another wu or 2. Cool temps are so nice in the summer.......

Please note that currently, FahCore_17 isn't supported on Maxwell GPUs due to a Driver bug. Nvidia is aware of it and once a fix is released, development can test FahCore_17 on Maxwell GPUs. Do note that there isn't any ETA provided for this. Also note that you can fold FahCore_15 WUs on Maxwell GPUs only in Windows. Since you have a Linux system, you can't fold on that GPU for now.

Are core 17 wu's better than core 15?

 

[thebluebumblebee]

Higher PPD potential due to the QRB. And, there are some core_15 WU's that are real stinkers, like the P8018's.

I seem to either get really low work with ~14kppd or really high work with ~30kppd. Is that why?

What I'm seeing is that you are getting P7620-1 for 5187 points and P7622-7 for 14093 points. The 14K WU's, IIRC, are the highest PPD WU's for core_15. What I remember about the P7620-1 was the 2.21 to 2.25 version upgrade of core_15 and the reduced PPD and how we used to switch back to the older version.
Short answer, yes.

My difference in ppd might also be having to do with I am going off estimated ppd, but it looks like you are talking about base ppd.

 

[thebluebumblebee]

Estimated PPD with core_15 is quite accurate. It's all over the place with core_17.
