Boinc detects cards this way:
ATI GPU 0: ATI Radeon HD5700 series Juniper ( CAL Version 1.4.792, 1024MB, 1360 GFLOPS peak )
ATI GPU 1: ATI Radeon HD 4700/4800 (RV740/RV770) series ( CAL Version 1.4.792, 512MB, 960 GFLOPS peak )
Collatz runs without problems on boths cards.

When boinc asks for WUs, Milky reports:
Message from server: No work sent.
Message from server: An ATI GPU supporting double precision math is required.
Message from server: Your computer has no NVIDIA GPU.
But ATI 4770 has DP. How to get work for Milky ?

Hi, I've a Q6600 host with a HD5770 and an EAH4850, the 5770 can only used
in Projects using Single Precision application/calculations.
The 4850, supports Double Precision.

Gonna swap the 5770 (S.P.)for a 5850 0r 5870, both Double Precision

Single precision, is only supported by Collatz C. and DNETC.(Don't know if I've the name correct). And Bêta testing AstroPulse app.'s,
OpenCL; BROOK/OpenCL, at SETI Bêta, which is also down at the moment.

BOINC (6.10.56; 32BIT) gives a warning, about the 5770(Device 0), but uses, after checking Device 1: EAH4850, even when another M.W task is already running on this card.

But it doesuse the card, whithout problems.
