Hello everyone, i have major problem when i disable ULPS on my setup(two Radeon HD 7870)

Everything works ok in games, but after i exit from game and try to access GPU-Z/Aida64/Hwinfo, i get hard lock.

I am really desperate, any help would be greatly appreciate.

I tried manually to disable it, i tried with ULPS control app, i tried with trixx, always same.

My GPU history: 8800GT, HD 5970, GTX 480, GTX 570 SLI, HD 6950, HD 7870 CFX, GTX 670, HD 7950 CFX, GTX 780 SLI, R9 290X CFX, GTX 980 SLI, GTX 1080 SLI

My CPU history: Intel Core 2 Duo E4500, Intel i7 920, Intel i7 970, Intel i5 3570K, Intel i7 3770K, Intel i7 4930K, Intel i7 5960X, Intel i7 6950X

Tried manual approach, did not work, even after using search function in registry.

The tool worked.

Haven't updated driver in like 6 months, forgot about whole ULPS thing, second card started to overheat , though my pump died or something, till I realized GPU was running @ 99% the whole time.

ATI can fry a lot of cards like that. Can't believe that bug still exists, it's been freaking years.

2015 and this thread is still helpful. Sad that it's still needed after 5 years.

A simile is like a metaphor.

What's the consensus as of now then (July 2015)? Leave ULPS on or off? Was thinking of adding another 280x to my Gigabyte Windforce but not sure I want them to stay @ high clocks permanently...

i just started on crossfire 2 x 280. The Afterburner has the Disable ULPS option unchecked by default so I suppose it's better left that way.

My main question is do we leave crossfire enabled at all times, or only when playing certain games?

For now, i leave it enabled when playing gpu intensive games. Would appreciate any response here.
