Setting up GPU2 on ATI cards!

[thebluebumblebee]

does this work with crossfire yet?

As far as I know. I think you have to turn crossfire off before F@H. You don't have to remove the bridge.

 

[crazyeyesreaper]

just have 2 montiors hook each card to a seperate 1 then disable crossfire in CCC start folding at home unplugg the second montior good to go. you can also get one of those active things bucknasty makes them on occasion lol. eitherway i have the 2 5850s and after bucks help i can fold with both no issue

that means it doesnt work with crossfire then

 

[crazyeyesreaper]

actually it kind of does work ive used F@H with crossfire on and both gpus get loaded but.. make the same PPD as a single card lol

 

[Athlonite]

turning CF off is what you used to have to do with the 6.20 GPU2 client that issue has been resolved in client version 6.24

to the OP you only need the -GPU switch when running more than one GPU client and as far as i know the second core on an HD5970 is not yet fully supported for use yet

my PPD for my HD5770
511pt = 2880ppd
384pt = 3665ppd

and just for shits and giggles
SMP2 on an athlon x2 7750BE @ 3000MHz = 1,026ppd A3 481pt WU

Hey, One of my friends is trying to do this via the instructions provided in this forum, but he can't get past the installer. (see attached screenshot)


He's got the 5770, which this forum supports. He is running Win XP, with the Win XP installer. He is also sure he has the drivers up to date.

Any ideas?

I can't see the screen shot. XP is normally the easiest OS to install F@H on. If you're having problems with our directions, try Stanford's, here (scroll down to "Installation (Console version)".

The screenshot is now attached to my first post. I shall refer him to that link, Thanks.

Ugh. That'll be what it is then. Sorry, I did not know that it needed authorisation. One sec, I'll upload it.

 

[Thermoelectric]

Okay. Here is the screenshot.

Sorry for double posting.

 

[NastyHabits]

Try having him add -forcegpu -ati_R700 to the command line on the desktop shortcut.

 

[thebluebumblebee]

I have hd5850 but I have hd4870 in the closet so can I put it in the second slot and dedicate it to folding@home or thats not possible?

ATI's drivers do not allow for different generations in the same system.

 

[Athlonite]

ATI's drivers do not allow for different generations in the same system.

Ah yes they do You just wont be able to use them in an Crossfire setup

you'll need a monitor to connect it to though and a descent PSU to power both

back to the OPs Q? just use the GPU3 systray client less frigging round as ATI HD5xxx cards are supported under it without having to use the -forcegpu -ati_R700 switch

I guess AMD/ATI is wrong then when they wrote me:

Response and Service Request History:

Thank you for providing us with an update. From the information provided, we understand that you want to configure a Radeon HD 4830 and Radeon HD 3870 in a standard configuration without ATI CrossFire activated.

Generally, we require identical series such the series as listed:

Option 1)

Radeon HD 4830

plus one of Radeon HD 4830 / 4850 / 4870 / 4890

Option 2)

Radeon HD 3870

plus one of Radeon HD 3830 / 3850 / 3870

NOTE: Identical series are required whether or not ATI CrossFireX is activated. Generally, Windows is unable to properly assign separate resources to individual drivers for graphics cards.

Best regards,

AMD Global Customer Care

What I saw was that the 3870 was at 100% even though it wasn't doing anything.

Also, Stanford said the following about GPU3:

We do not recommend that you use this client with an ATI GPU at the moment since there is no advantage and you are potentially exposing yourself to new bugs.

 

[Athlonite]

well I'll tell that to my mate who's got an 4670 + 5770 both running happily together in one system using windows 7 x64

as for what Stanford say and what is actually going on can quite often be two different things
I have had the GPU3 systray client v6.32 running since they put it up for public consumption it downloaded core_11 and associated WU's and has been happily crunching 24/7 for the last 2 months and completed over 200 WU's without error

Woh! Necro, but I think this might be useful. Environment variables seem to help! I hope I'm not missing something.

4870 W/O environment variables
2860.14 ppd - P5741

4870 w/ environment variables, no restart
3129.96 ppd - P5741

As far as I know. I think you have to turn crossfire off before F@H. You don't have to remove the bridge.

That killed folding on my GPU :shadedshu...lol CF stays enabled always no matter what...lol...oh well cpu is good enough for me on the rig in the sig.

EDIT: Actually I didn't have to disable CF to get it folding on one of 4 GPU's...unfortunately its the main GPU. I would Of rather it was on one of the slave GPU's but it doesn't affect HD but I bet F@H is affected by the HD.

 

[tuktuk1984]

Have anny user an Idea the beta or release Termin For Folding with OpenCL on ATI 5870 Cards?

 

[Athlonite]

sometime between "now" and the next 5 years

5) Environmental variables:

Add these environment variables. They will minimize your CPU usage.

BROOK_YIELD 2
CAL_NO_FLUSH 1
CAL_PRE_FLUSH 1
FLUSH_INTERVAL 128

FLUSH_INTERVAL can be set anywhere from 128 to 256. Lower number for stability, higher for greater PPD output.
Forum members have had success with settings betweeen 128 and 200.

Please post in this thread if still experiencing issues. Good Luck and Good Folding!

Where do I put these in, haven't messed with stuff like this in the past when GPU folding.

Where do I put these in, haven't messed with stuff like this in the past when GPU folding.

1. Right-click My Computer, and then click Properties.
2. Click the Advanced tab.
3. Click Environment variables.
4. Click one the following options, for either a user or a system variable:
* Click New to add a new variable name and value.
* Click an existing variable, and then click Edit to change its name or value.

 

[dark2099]

Is doing it as system or user better, or is that a non factor?

 

[oily_17]

Well if you have alot of user accounts on the PC, just do it for your own user.

Or if you are the sole account then just do it for System and be finished.

 

[dark2099]

Interesting, in Win 7 I just had to add the BROOK_YIELD variable.
