Why does SIV and BoincManager give different number to the GPU's on 5970 card.
SIV says there way of giving numbers to the GPU's are correct.

see here.



Any ideas...???

SIV says there way of giving numbers to the GPU's are correct.

Well, when the developer for that application says his way is the only correct way, then that must be it. Case solved. Why bother to ask?

But here's the thing, SIV can use an OS specific API to do all the hard work of polling the videocard for it, whereas BOINC needs to be showing the same numbers when compiled on Windows, Linux, FreeBSD or OSX, and where applicable and supported. It cannot rely on an OS specific API. It will also have the detect Nvidia GPUs, AMD GPUs and Intel GPUs and put them in a certain order, these being 1 - compute capability, 2 - software version, 3 - available memory and 4 - speed.

Only after those 4 have been ascertained, will BOINC give out numbers for GPUs and show that in the start-up messages. And they'll be the same numbers whether you run Windows, Linux, OSX or FreeBSD. Easy, huh? :-)

From what I understood, he used ATI way of detecting.
