I had to remove the Nvidia card in order for both GPUs to be usable/enable CrossfireX. I don't know why or how the Nvidia interfered with ATI, as both should work in same system...



They will all play together. The Crossfire cards need to be in the first two slots. The Nvidia card can go in the third.
I use this setup in one of my i7's. The GTX260 is devoted to Seti.

Hi Morton

I run three boxes each with twin 5970's.

All are cross fired, and all GPU's work when plugged into the top right socket on the card. IE: the one furthest away from the mobo.

Windows 7
BOINC 6.10.xx, (now .40 with the downtime.)
Hope this helps.

PS: As a side effect of this setup, I can not run Collatz.

You can fix the progress issue now, see here http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=1600&nowrap=true#37333,

And here for the apps: http://www.arkayn.us/milkyway/index.html

As to the other, going slow issue, I have noticed it only happens on my Windows 7 boxes as well, and not the Vista one.

Yep, that is a different problem that has been fixed. Basically the WU sits at 0% then will jump to 143% and work backwards to 100% then uploads.

You can download a manual app (.22) if it bothers you, otherwise just wait for a few days, and normality will be restored.

I too, am having the same problems.

I have three machines, and they all do it.
One
BOINC 6.10.34
Cal 10.1
Two
BOINC 6.10.34
Cal 10.1

Three
BOINC 6.10.24
Cal 10.2

I have tried different versions of BOINC and Cal drivers to no avail.
The screen refreshes VERY slowly, so aborting the offending files takes several minutes each. After whichever file is slow, things return to normal.

Shutting BOINC exiting, then restarting sometimes fixes it, sometimes not. likewise shutting the whole computer and rebooting, sometimes fixes it sometimes not.

These days I just abort when I notice the afterburner monitors sticking at 30% of flatlining.

A major nuisance and very hands on.

I crossfire my cards, twin 5970's.

Each WU runs on a separate GPU. The reason for Crossfire in Crunching is just to tell Windows use all the GPU's available to it.

The alternative, to Crossfire, is to use dummy plugs in the other card or the VGA cable if present.

OK, I have some weirdness going on here. On identical i7's, except RAM which is 8GB for one, and 10GB for the other.

Both machines run twin 5970's.
Both machines run BOINC 6.10.34.

On the 10GB machine RAM is about 73% or 74xx MB.
On the 8GB machine RAN is about 60% or 49xx MB.

The 10GB machine runs normally, except longer finishing times, and staying at 0% then bouncing to 143% and working backwards.

The 8GB machine runs for hours at 0% before finishing. The GPU usage meter also shows 0%.

Looking more carefully I note on the slow machine the WU's are in the free_5_32xxxx range, on the OK machine the WU's are in the 64 - 65xxxx range.

On my third i7 the usage meter shows averages of 29% over four GPU's, compared to 91-94% on the OK machine.
The third i7 also has 10GB RAM, shows two tasks counting backwards after 2:00 hours run time. and two at 0% after 1:59:49 hours run time.

Holy Crap, I just got a ! Do you want to change the color scheme to improve performance msg. Sheesh, and I thought Cosmo was memory intensive!!!!

EDIT: I brought the resource meter up to see what is going on, and lo and behold Wu's show a normal 100Mb each. Just as I was thinking, "That's weird" they finished, new ones started, available RAM jumped from 77MB to well over a GB and tasks running as normal at 96 - 98% usage. They are taking under 2:30 each. This machine is water cooled and O/C'ed to 800MZ on the cards, So I now got two OK machines and one dud!

You sure can.

Get a eight core CPU.
Seriously, MW downloads 6 WU's per processor to a max of 48. So a eight core CPU is the optimum. Obviously they won't last any longer, unless you restrict to GPU only like me.

I have a GTX260 that I run wih twin 5970's in Xfire mode so it is possible.
I also have a 4770 that I run with twin 5970's in xfire mode, so that is possible as well.

You will need a separate dummy plug or monitor ( I use the spare VGA cable) for the second monitor. And also extend the desktop across both screens in Windows.

I have had this config working in both Vista and 7, so you can do it. Getting the right cal driver can be a bit tricky though. 9.12 Hotfix seems stable for me.

I go for a version of two as well.

I like this screen with the numbers on the right.
http://lcarscom.net/gallery.htm

Pure eye candy, BUT they make it LOOK like the computer is doing a hell of an amount of work. Make sure to allow for multiple GPU's / CPU's or you will give the game away! Perhaps, a translucent colour for slices of the Galexy that have been work on, with red for the units currently being crunched on a project wide basis. Plus the eye candy above.

Hahaha luxury. I run 1:45 per GPU x four GPU's. (5970's), So how many should I have stocked up?

Post:
They come in the Mobo box, or with the higher end graphics cards. You can buy them separately. The other thing I do is to is to connect each card up to a monitor, one with the VGA adaptor, this seems to work for me.

If you go the seperate monitor route, you will also need to enable the desktop across all monitors in windows. Dummy plugs work as well.

I do have four GPU's in a crossfire setting with only one monitor connected. which works for me.

Maybe its just a glitch, try resetting the project, and see how that goes.

Post:
Possibly, I have never over voltaged the core, mainly because I don't want to invalidate the warranty. Note the cruncher that did the extreme OC'ing had temps of -20 outside. And, he did it with the window open to provide cooling for the card. Heat is not your friend.

Mine hit 102 degrees then the card started protecting itself to bring temps down to an average of 97 degrees.

Post:
Probably not. What has happened is that the core temp has got too hot and the card is trying to cool it self down. It does this by turning itself on and off.

I have the same problem where one of my cores is running about half the time at about 25%. Reduce the OC'ing or cool the card more and the problem will go away. I will be converting the problem card to water cooling today.

There is a review of the 5970 blocks I will be using.

This is not the cheapest company to buy stuff from, but I like the security of using the best metal fitting etc that I can find. There is a serious amount of hardware depending upon it in my machine!

On two of the boxes I am using Asus P7P55D Deluxe, and in one the Asus p7P55D Pro, which is the non gamer version of the above. They run the 1156 socket chipset I use.

The Pro version is the oil cooled one, which will end up with the four 5970 GPU's oil cooled and a Fermi GPU also oil cooled. According to my supplier the Fermis are buggers for heat. Even the single entry level GPU will run 200 watts.

I am about to install the other 5970 now, then on Tuesday we will do the conversion to oil cooling as the blocks for that have also, finally, arrived.

BTW: When I was cooling one of the the twin 295's I had in the box, with air, they ran in the high 80's to max at 91 degrees. When I converted just one card the temp dropped to a steady 38 degrees on that card and its neighbour dropped to low 80's. An eye popping difference I thought.

That's exactly what I am saying. I am using the NVIDA 260 to crunch Seti and the ATI 5970 is crunching Milkyway, on both GPU's.

It was a concern for me because, one of my personal goals, is to have every project I start go over one million credits. So no GTX260 no Seti.
I was also, using MSI Afterburner 1.4.2, able to overclock the two 5970 cores, but leave the GTX2620 core alone.

Now that the whole thing is stable, I will, tomorrow, max out the system by adding another ATI 5970 to the mix and see how we go.

OK I have found the magic combination, finally!

BOINC 6.10.29
Cal 9.12 hotfix.

I now have Seti on the GTX260, and M@H on the 5970.
I did have to detach and reattach to get it all going.

Lets hope it is the same arrangement when Fermi comes out.

I have one box with a GTX260 which I use for Seti. I recently, well yesterday, installed a 5970 as I want to lift my MW performance a little.
I was running BOINC 6.10.29 happily until I installed the drivers for the ATI card.
All I get now is the message "Connecting to localhost" in the manager, with the client MIA.
I downgraded to 6.10.24, then 6.10.18, in case that was the problem but still the "Connecting to localhost" message.

MSI Afterburner shows all three GPU's are present, and I am running Windows 7. Is there some BOINC config file I need to modify?

EDIT: Given the ATI driver seems to be the cause of all my problems, I should say what it is, doh. Cal 10.1 Beta.
