New PSU installed, set optimization and after a few WUs, throughput 6-7 times what it is under the default config. What are acceptable temps to keep the GPU at?

It stopped Cadillac'n last night. See the R7 R9 thread.

See the news that Collatz was going to start using CreditNew today? It will reduce credit granted to values in line with other projects that use CreditNew. They're also going to reduce all the existing credit to values proportional to the CreditNew values.

Did they post that for April Fools or is it real?

In order to assure that the oldest software will be used, all applications will be migrated to COBOL and entered via punch cards.

Was the final give away that this was a leg pull. :D

Does the filename end with .config or is the Type CONFIG file? If not, it's not the correct file. Once you locate the correct file, right click on the filename. If you have the option to Open With, select that. If Notepad is an option, select that app, else select choose and find Notepad. Then add the contents to the file. Don't forget about the app_config.xml file.

I thought I did write a dummy's guide :D Though it could be done with an update. Added to to do list.... Boinc has finally changed over to calling ATI AMD years after the change. At least a few project developers have :D
With the four new units choices available for collatz you now have many config files , micro, mini, solo, and large depending on your choices on your account page at collatz . Simply paste the changes into each one as each is originally empty. When I said open , as Scole said, find the config file, right click on it and open with notepad. If you are having problems then pm me and I can walk you through it step by step. With your 7990 you should be flying through these at a ferocious rate.

Arr matey, i have just gone and sussed it out :D.

As i type it has completed 50% in 11:00 and 11:07 respectively.

What it was were > solo_collatz_4.07_windows_x86_64_opencl_amd_gpu was opening in Microsoft Visual Studio and it brought the window up but wouldn't let me read the file, so i changed it to open with notepad then it opened and it let me do the.....
verbose=0
items_per_kernel=20
kernels_per_reduction=9
threads=8
sleep=1

Abandoned the 2 it was doing rebooted and voila, cheers.

EDIT: gpu usage has shot up from 34% to now 96% and the 1st 2 units have completed in 21:57 and 22:46 solo units that is :bounce:.

Temperature's up from 62c to 82c, that's ok the card can run at 85c max continually according to Msi.

EDIT 2 : just checked the last 3 hours worth on Temujin Stats and its banging 60,000+ an hour out, ferocious indeed!!!

Am only running the cache i got last night down and that's me till next weekend.
