Had another look and it also says cc_config.xml not found using defaults but its definitely there and set up with notepad as instructed.

ok, just some thoughts so don't be insulted :D

first it is in the folder c:/ProgramData/BOINC ?
2nd, it is called cc_config.xml not .txt ?
3rd have you typed the contents here or did you cut and paste. If you typed check the sytax is the same in fact..... just noticed .... sorry what you have typed is wrong

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

your missing the last >


If that is just a typo try running it without the config file. Seems weird I know, but the 7990 is seen as 2 cards by boinc and used as such without the config file. With my 6990 ( dual card ) I do not need the config file and I have a 6970 there to, so it sees and uses all 3 cards without the config file. The dual card seems to confuse boinc.
If this doesn't work let me know and we can see what else we can try.

1 yes
2 yes
3 yes
It was a typo and the syntax is correct, i will dump the cc_config now and re start it and see what happens..............................................................................................................
no joy still says cc_config.xml not found using defaults, it even said that with the cc_config.xml in there?????

It has the second card connected to my tv's media box and is showing as a second desktop.

Yes it sees the 7990 as 2 separate cards without the cc whatsit, it also sees the 7750 just says not used and ignored by config, with or without the cc_config

Going to disable the 7990 for a short while and see if the 7750 will work without them in.

If it doesn't work can you post the start up log in boinc down to where it starts projects running. Advanced > event log

Edit, disconnect the card from the media box and try again. It may be windows causing the issues and you may have to extend the desktops across each other with catalyst.

Edit 2 which version of Boinc do you have and when you boot, do you see the bios screen etc or is the screen blank or staticy until you get the windows desktop ( this happens on mine )

Right the 7750 works fine (slow as 2 minutes to do 10% its trying to do 4 units like) have disconnected the media box and boinc still sees it but just wont play.

When the PC boots i see the bios and the boot up screen until it hits desktop.

Then what I would try is the following. ( again no offense intended if I'm teaching you to suck eggs )

Replace the cc_config.xml file. ensure you save as in notepad and make sure the extension on the file is .xml and not .xml.txt

Reboot and check. If not

Move display output cable to the last gpu IE last pci slot used on the board. Reboot and check. If not.

Reinstall AMD drivers using the clean install option. If not

http://boinc.berkeley.edu/dev/forum_thread.php?id=8378 download and try one of the beta versions of boinc. I use 7.3.15 with no issues but no reason not to go to 7.3.18 or 19 ( I will be when I get home )

If none of the above works we are scratching heads. I think the important part here is to get the cc_config file recognised as I think that is the issue here.

:happy1:

There she blows, i sussed it out.

You cannot name the file cc_config_xml because when you do and then look at property's its called cc_config.xml.xml and it will not recognise it, so i had to just name it cc_config and then the property's say its called cc_config.xml .

Cheers Alez :pirate: :bounce:.

So you have the app_config.xml you have cpu_usage and gpu_usage set to .25? Does that provide better overall throughput?

Hmmm yeah it does its doing 8 in between 1.30 and 1.35 so at 1.35 its 16.875 seconds per unit where as without it it was doing one in roughly 20 seconds so yes its quicker and you can do more.

I have had to abandon my 2 gpu thing for a short time as when i have the 2nd one in the 7990 gets ridiculously hot like 100c+ and then the protection on the card kicks in and slows the thing down to 500mhz and still hits 90c+, it was sitting in the pcie slot under the 7990 and blocking the air flow to it, so its out for now and i have ordered a water cooling rig for the cpu which will arrive next week sometime but i am out of funds till next pay day now so i cant extend the loop till June the 8th as the gfx block is £112 so when i get it up and running i will slap the hd 7750 back in as it shouldn't matter when its water cooled, that's if i don't fubar it and blow all my comp up with a water leak :lol:.

Ooooh, sounds like you'll be having some fun soon then!!
I'll look forward to your updates on water cooling, it's something that has crossed my mind but I haven't got any closer than doing some reading so far

I see you are going to cool your cpu and 7990. What radiator and pump are you going to use? I'm still a newbie to water cooling, but my i7 3770k uses all of a 240mm and another similar cpu uses all of a double thick, duel fan 120mm. They are both closed, self contained systems though.

Alpha cool pump/res, 240 mm radiator 2 x 120mm fans, phoybia cpu cooler, 8 x compression fittings, 3 meters of 10/8 mm tubing and a EK Water Blocks EK-FC7990 SE - Acetal for the 7990, i will post everything in the thread i have created as i get going :).
