try different ATI drivers. Also what i have found is that If i installed Nvidia drivers it didn't cause problems

I've tried different ATi drivers, I'm seriously thinking of selling the Nvidia card and buying an ATi...in which case I'd have to stop folding, I'm not willing to use 1 core of the X4 955 just for F@H.
Maybe I'll try an OS reinstall to see if that fixes things

I wish you luck. And don't forget about the tweaks you can do to lower CPU usage on ATI cards when folding. You don't have to give up a CPU core only ~0-12%

I have just installed folding@home client for CPU and GPU. This is what I`m getting. Isn`t that low score ? Advice please.

 

[p_o_s_pc]

that about normal for your setup. The CPU is alittle low but thats because of your GPU sucking the Cycles

Are the drivers crashing when it completes a WU? Please give as many details as possible.

Would broken solder bumps explain the issue? The core is a 55nm G92-280-B1 made on Week 41, 2008.

Not sure, but if it saves it from the trash its worth a try.

You appear to be running the uniprocessor client, judging by the credit of the work unit you're folding on the CPU. You'd see a gain if you follow this guide. A few things changed, for instance you won't have to get a second file to 'drop in', all you should need is the one installer for your version of Windows. Also, now you should go to 'http://fah-web.stanford.edu/cgi-bin/getpasskey.py and input your folding name to get a passkey. When you're setting up your client on the first run, it will ask you username, team number and the passkey (in that order). You can input your passkey here and then continue with the setup as normal. Once you've completed 10 CPU work units under that passkey, you will get a bonus for how fast you complete subsequent eligible work units. You should see a fair boost over the current CPU installation.

As for your ATI card, there are some specific arguments you can apply to have it fold more efficiently. I don't know these off the top of my head, but one of the ATI guys can help you if its not in one of the ATI specific setup guides.

r9 Here's my environment variables I use on my PC with the ATI card:

BROOK_YIELD 2
CAL_NO_FLUSH 1
CAL_PRE_FLUSH 1
FLUSH_INTERVAL 128

They make the GPU client submit work to the CPU in a much more efficient manner greatly lowering the load on the CPU. (People have reported going from 50% usage down to 10% or less). On my PC with the 4850 it gave me 150 to 200 more PPD on each project. More importantly it greatly increased stability, so much so that I can fold on my card, and crunch on my CPU all while surfing, e-mailing, and even playing games. Although the CPU folding takes a major hit while gaming, it does not crash! No more EUE's or UNSTABLE_MACHINE ever.

You can experiment with the last variable. You can set FLUSH_INTERVAL anywhere from 128 to 256. The higher number gives slightly better performance, the lower gives more stability.

EDIT: I found my original post - #353 in this thread. I found that after setting those environment variables, I'm only using 3% CPU when all I'm doing is folding.

Sometimes they crash when the 8800GT finishes a WU, sometimes they crash when I start a game (NFS shift, mostly), sometimes they crash during a WU, and sometimes they crash as soon as I boot up. It's the "The Display Driver Has Stopped Responding" or whatever error that Vista and 7 give sometimes. This has only happened since I switched over to the AMD setup with the 785G motherboard instead of the Intel setup with the Geforce 9300, so I think it's a driver issue between the 8800GT and HD4200. I think this weekend when I have spare time I'll try re-installing the OS if it doesn't resolve itself by then, otherwise I may sell the 8800GT and get a HD 4830/HD4850

 

[p_o_s_pc]

go for the 4850 as its an upgrade from the 8800GT and the 4830 is neck to neck with the GT

I'd really like to get this issue resolved and stay with the 8800GT, it already shreds all games I play, and I don't want to have to give up my 4-5k PPD in F@H

 

[r9]

I`m going to try yours suggestions and thanks for the help. At the moment I`m at work as soon I get home I`m goig to try it. How faster is this SMP client compared to regular one that I use ? And is this going to give me similar performance compared to VM client on linux ?

As you suggested I`v installed SMP client instead of the one I`v had. Now the PPD if the CPU has increased but now the GPU wont go to 100% utilization. I guess I will have to change the way GPU talks to the CPU those environment variables you mentioned. How to change them ?

Reconfigure the GPU client to Low Priority and the CPU client to Idle priority. You can do this by changing the arguments in the shortcut properties to -configonly, change only the setting(s) necessary, and change the arguments back to their original configuration.

This should speedup my setup ?
My second PC is Athlon x2 5200+ 4gb ddr2 ATI 3650 512ddr2 and it is doing 800 ppd can I speed it up ? It is running GPU and CPU client.

The priority changes that Buck suggested will result in speed increases for both setups for the SMP client. The environmental changes will speed up both CPU and GPU. Don't expect much from the 3650.

Buck, can we get a thread under Folding Essentials specifically for ATI Folders? Nasty, are you up for creating the thread and then Buck can move it?

 

[theonedub]

internet was down for 3 hours this morning... Rain on the way so I can expect more ISP issues and in turn lower production in Folding. I think F@H should have a work buffer like WCG. At least when my ISP fails my rigs still crunch and upload results later.

I'm all for it, but I am lacking ATI knowledge. If anyone can do the write-up, I will sticky.

I've been having bad luck lately also. Came home tonight to a solid pink screen(???wtf) on one of my rigs and I have rigs crashing intermittently during the night. This does not make for a good night's sleep

my apologies for the theft

 

[johnspack]

Sorry, the cat used up it's ninth life apparently. I was wrong about the bios fix. I was hoping so bad it would work. The Palit gtx280 is just a crappy card. I'm done for now. Hopefully will be back folding within a few months. Fold On!

Sure thing. I'll give it shot. It will be a few days because I'm heading out of town for the weekend.

 

[r9]

OK I have done what you suggested installed SMP client for CPU and changed environment variables.
And guess what before I did all of this I was doing around 3600 ppd after I did the changes I was doing 2300 ppd . So I deleted all and restored previous conf and now I`m doing around 3200 ppd .

 

[p_o_s_pc]

is ~2.8k(477pt WU) good for a stock 4850?

 

[BUCK NASTY]

is anyone having trouble getting -bigadv WU's?
