Just as a matter of interest, what temps were you hitting on your northbridge?

45C. But it's water cooled too. I used to have a small fan blasting at it, got tired of the noise.

I'm having problems with fahcore_14. If I get two of them going at once (such as 2 of the 1888's) one of my clients will EUE. So much for the new version.
I was hoping that this Folding system would be set it and forget it, but I'm finding that I need to check on it every 4 hours or so.

A8N SLI Deluxe
4000+ S939 single core (WCG 80%)

2GB RAM
2x Asus 9600GSO/384
WinXP Pro

This is frustrating to the nth degree. I was NOT having problems with running 2 instances of fahcore_14, but upgraded just in case. Now I CANNOT run 2 of them. I'm going to restore the old versions. Had to double check the calendar to make sure it's not the beginning of April.

Ok I'm running a HD3870X2 and have a second monitor plugged in. This allows me to allocate a second Folding at home GPU with a different ID to my second GPU core.

However, when I run the second one it just uses my GPU0 and not GPU1. My GPU1's core never spikes in usage and my Graphics Card PPD gets divided by 2 with part of it going to FHGPU0 and FHGPU1.

How can I get my second core to actually do the work?

I haven't gotten any points update since noon on Wed morning. I've checked my logs and the clients are still completing wu's and sucessfully sending them to the server, but they're not showing up. Anybody have a clue?

No one has gotten any points, be it TPU, the Canucks, OCN, or EVGA. Something is wrong with Stanford's servers, and no points are showing up. Expect a lot of points either today or tomorrow

Somebody in one of the other threads mentioned something about them moving servers.
Think Chickenpatty was the culprit.

And so as not to doublepost, I have a question. Running the command line version of the FAH client. Set to start on bootup, which works fine. But I need to be able to disable it while gaming, and using task manager seems overkill. Any thoughts?

Go to the window of the F@H client, and hit:

Control+C

Go to the window of the F@H client, and hit:

Control+C

Thing is, when it starts up with bootup, there is no window. Am I missing something obvious here?

So you have it set to start as a service?
Unset that, and then go to Start--All Programs-->Startup-->(right click)-->Select "Explore"-->Create a shortcut to F@H
That's what I do

Guys,

I am facing this weird issue on one of my new builds for my friend.

He got one Zotac 9800GT and he bought 2 xfx 9600GSOs. I setup 3 nvidia clients as per the post. He has installed win7 64 bit on the new rig. I had read on the HCN post tht on win7 we can run multiple clients with the -advmethods -forcegpu nvidia_g80 flag without using any dummy plug.

Two of the three cards run. But the third card gives EUE. I changed the slots. But its always one that gives EUEs. Before only the 9800GT was EUEing. After I changed the slots, its one of the GSOs thts EUEing.

I installed the latest 191.07 drivers. By the way the mobo is Asus WS Reveloution which has 6 PCIe slots loaded with latest bios.

 

[El Fiendo]

Hey Dusty, I had this issue not too long back where my extra PCI-e slot wouldn't work no matter the card in it. I solved it by getting the new beta cores they've released. These won't be downloaded by the console client as they're still in beta, but they've worked like a charm for me. Go to http://www.stanford.edu/~pande/Win32/x86/NVIDIA/G80/beta/ and grab "Core_11.fah_v1.30" and "Core_14.fah". Download them and place them in the GPU console folder (replace the current core 11 and core 14).

This should work, let me know if it does. I'm not at home right now but I'll try and remember if there were any other settings / flags to use. I assume they're all separated by the '-GPU 0, -GPU 1, -GPU 2' flags.

 

[thebluebumblebee]

That seems to be the problem with this method, that is, it works for up to 2 GPUs but has problems after that. On top of that, I'm having problems when both of my GSO's try to do an 1888pt WU at the same time, and I'm using XP.

 

[El Fiendo]

The method here works fine for my 3 GTX 260s. I'll double check the logs but I'm pretty certain they've been running error free for about a month, maybe a month and a half now.

Note, I am using Win 7 RC 7100.

Edit: I just realized that the latest Core 14 (26/10/09) is actually newer than the Core 14 beta (14/10/09). The link to the newest core 14 is http://www.stanford.edu/~pande/Win32/x86/NVIDIA/G80/Core_14.fah. It should however download whenever you run the console client though. The Core 11 is still in beta however, and I still recommend you get it.

If you're sure you have the latest version, try grabbing the beta Core 14 (http://www.stanford.edu/~pande/Win32/x86/NVIDIA/G80/beta/Core_14.fah) Blue, and see if it fixes it. I would think it would just download the new Core 14 on you, but its worth a try.

 

[dustyshiv]

El,

After download, should I rename the core14.fah to FahCore_14.exe? Cos in the work dir...theres no .fah files.

 

[El Fiendo]

Yep, I believe I followed those instructions and had it work out as per http://fahwiki.net/index.php/Downloading_FAH_Core_files_manually. It was a few weeks ago so its a little fuzzy, but I seem to recall yes.

Note: It seems that some earlier versions of Winrar do not handle .bz files as expected with regard to the naming convention of any files contained within. If this happens, extract the file, which will probably be named Core_xx (with no extension) and manually rename it to FahCore_xx.exe (xx still refers to the core number).

If this doesn't work, let me know and I'll either upload my FahCores (proven working) or try and find a couple of downloads that are already '.exe'.

 

[dustyshiv]

El,

Could you please upload your working 11 and 14 cores?

 

[El Fiendo]

Sure, it'll be 4 hours or so until I'm at home though.

In the meantime, try this EXE of FahCore_11. http://www.stanford.edu/~friedrim/FahCore_11.exe

Do you know what WUs it crashes on? I have a sneaking suspicion its only the FahCore_11 WUs and you haven't come across any FahCore_14s yet.

 

[dustyshiv]

Hey El,

I downloaded the core and put it into the dir. On launching the client..it says working and after a few seconds reports that it sent the results successfully. On checking the logs, I find that it says UNSTABLE MACHINE. I dunno whats wrong?? Should I use the dummy plugs?

 

[El Fiendo]

Eh, weird. Somethings not right.

Here are the Cores I use on my SLI no dummy plug system.
http://uploading.com/files/b29a1e42/FahCore_11.exe/
http://uploading.com/files/d9ma5244/FahCore_14.exe/

What are all of the flags currently enabled?

 

[dustyshiv]

El,

I have enabled the following flags

"C:\Program Files (x86)\Folding@home\Folding@home-gpu\Folding@home.exe" -gpu 1 -advmethods -forcegpu nvidia_g80

I just realized tht my friends rig is powered by a Zalman 460W PSU. CPU is i7920 and there are two 9600GSOs that have a 6pin PCIe power connector and one 9800GT which is powered by the slot. Would this be the reason why the third card is giving unstable machine EUE?

Appreciate your help buddy!!

Yup thanks I was looking for that. I've done everything he says to do and it still won't show any core utilization for GPU 1. I still have it fold though. Maybe its cause I can't exit Crossfire.

I'm having the same problem now after upgrading to Win7 Ultimate 64bit. The 3rd GPU on my 780i board keeps getting "mdrun_gpu returned.....unstable_machine". Looks like i'm going to need dummy plugs. I have tried the new cores the El referred to and have entered the "force gpu" argument. Any other ideas before I hit up Radio Shack?

 

[El Fiendo]

Hey, do you guys have them in SLI? I just realized my rig isn't in SLI, yet both secondary cards don't have a dummy plug. This is very weird seeming how most say you need SLI enabled. However, checking the logs these cards have a long history of working nice and fine. I can't explain it. In case I'm overlooking something, I'll provide the two links that helped the most in me setting this up. One deals with the cards without dummy plugs, the other deals with mismatched cards in the same system.
