How do i check temps/speed etc of a secondary card?

[Maximilian]

Im dabbling with mining atm and ive got an HD7850 in a rig with an i5 4570, if i use the HD4600 integrated graphics I lose the ability to check the 7850's temps and voltages etc, GPUZ and MSI afterburer dont show anything.

Its not a big issue tbh but is there a way around this? I had a 5850 before and it was fine with temp monitoring even when using the HD4600.

Try HWiNFO64:

That works for me when I have my HD4000 set as primary and no other program can see my dGPU.

Are you using a VGA Dummy or something? I recall than when I had my old AM3 build with two Radeons 5770 but using the integrated Radeon 4200 as main GPU, GPU-Z reported totally invalid info for the Video Cards (Like, 32768°C or something like that). That was until I used the Extended Desktop option with a Monitor plugged to them, then they started to behave as expected (Besides for monitoring, it was also required to make them available as a OpenCL device, else I wasn't able to mine).

Cool, I can see the clocks with it but not the temperature. Should be fine though I just tested there using the 7850 as the primary display and the highest it got was 60*C.

Seems the amd overdrive dosent work when using the intel graphics though as the clocks are 860/1200. Guess I can put this card into a dedicated mining rig and stick the 5850 back in this main rig.

Dont know what a VGA dummy is, looks dangerous, sticking metal things into the VGA port lol. Its just a DVI cable plugged into the monitor is all.

Yes, never had to mess with dummy plugs even when I had headless rig last year.

HWiNFO64 gives me the temps, but it must be card or system specific. But I do know to force overclocked settings to a card which is not primary: VBE7. Not without risk as you'd be flashing the BIOS but doing so allowed me to undervolt my cards (Gigabyte locked @#!$3#! card), whereas nothing else would let me touch the voltages.

Sweet, ive used radeon bios editor before to flash my 5850, never knew the 7xxx cards could be flashed though, ill look into that.

Its a saphhire dual x 7850, dont know if the voltage is locked or not but the maximum clocks CCC allowed were fine 1050 core and 1450 memory seemed stable, mines ~360khash at that which is what I was gunning for.

Okay well operation flash the bios hasent panned out. Cant make a DOS USB boot disk (i suck and so does that HP utility the guides mention), atiwinflash dosent work either, seems like the bios might be locked and the -f -unlock 0 or 1 command dosent work.

Its okay though, low tech workaround!

1. Boot up with monitor plugged into AMD GPU
2. Unplug it after boot and plug it into the motherboard

Success! Using intel GPU but maintaining the AMD overdrive settings Seems okay so far, no weird behaviour or anything.
