BOINC application installed on Acer Aspire, model E5-522G-62QT (NX.MWLER.004).

BOINC application correctly detects and uses both GPUs - CPU internal and external.

| OpenCL: AMD/ATI GPU 0: Mullins (driver version 1800.8 (VM), device version OpenCL 2.0 AMD-APP (1800.8), 1648MB, 1648MB available, 128 GFLOPS peak)
| OpenCL: AMD/ATI GPU 1: Hainan (driver version 1800.8 (VM), device version OpenCL 1.2 AMD-APP (1800.8), 2048MB, 2048MB available, 320 GFLOPS peak)



However, in configuration on the site I can see two internal GPUs.

[2] AMD Mullins (1648MB) OpenCL: 2.0


(see it here -- http://setiathome.berkeley.edu/show_host_detail.php?hostid=8015962)

Fix it, plz.

The site will always display a "mismatched" pair of GPUs as a pair of what BOINC believes to be the more capable GPU - it is a "design feature" and has something to do (or at least had something to do) with the scheduling of tasks and the guesstimation of flops....

I think this is only cosmetic - to simplify the web pages only the "best" GPU is shown.
In your case the "best" GPU is determined because of "OpenCL 2.0"

BOINC reports all the details to the server, I recently made 2 posts about that:
http://setiathome.berkeley.edu/forum_thread.php?id=79591&postid=1789475#1789475
http://setiathome.berkeley.edu/forum_thread.php?id=79738&postid=1793876#1793876

Applications know where they run and detect both GPUs OK:

Running on device number: 0
http://setiathome.berkeley.edu/result.php?resultid=4970229273
Low-performance GPU detected, default period_iterations_num set to 500
Used GPU device parameters are:
	Number of compute units: 2
	Single buffer allocation size: 128MB
	Total device global memory: 1648MB
	max WG size: 256
	local mem type: Real
	LotOfMem path: yes
	LowPerformanceGPU path: yes
period_iterations_num=500


Running on device number: 1
http://setiathome.berkeley.edu/result.php?resultid=4970875081
Used GPU device parameters are:
	Number of compute units: 5
	Single buffer allocation size: 128MB
	Total device global memory: 2048MB
	max WG size: 256
	local mem type: Real
	LotOfMem path: no
	LowPerformanceGPU path: no
period_iterations_num=50
