I know what you mean man, even pure distilled shouldnt cause such a volatile corrosive effect in such a short time. I also agree with you about not running pure distilled, as I myself run distilled, plus corrosion inhibitor additive. I feel the same way about dyed coolants, because it has to come out of suspension at some point.

This is what I use in my coolant, except I have access to it directly. There's actually newer G12+ and ++, but I haver to see what changes were made. I haven't had any issues with it so far either. One thing to keep in mind with this pink coolant is that it turns clear if you use new Primoflex tubing. It seems the tubing absorbs the color within hours, as it did on this weekend on my new loop. Coolant turned completely clear by the next day.

im a new owner of a Powercolor 6990
today's my 7th day of tryin to get it right..but..my 6950 was runnin better than this and i know that i have a huge bottleneck..we tried it in a 1055T and still it was lagging and at dirt 2 we just had 40-50fps and the 2 gpu workin at 43%..

If your still having problems, I would do a full uninstall (Express Uninstall) of the drivers and use driver sweeper. Then reinstall the drivers
post #1930 of 4103
i always do that as well as using the driver sweeper in safe mode
i really love my 6990..and the thought of exchanging it here with a 580 directcu2 with a price difference of only $23?its so unfair..i'll try for a 6990 replacement today..and soon i'll sell my psu for some more juice..what i have is the 11.5a hotfix..im still downloadin the 11.5b you provided..thanks again
