Infinity users - can you try something for me? (Diagnostic LED idea)

Posted this over on AMDMB/PCPer, but the guys over there seem more preoccupied with flaming DFI :rolleyes:

As I've been trying to troubleshoot people's dead Infinities, I've been thinking how much easier it would be if the boards had the diagnostic LEDs. It's only a theory, but can someone test whether there's voltage going across the points where the FrontX LED header would be on the LanParty boards? There should be solder points immediately to the right of the front USB port header, they're in the format;


. . . . <-- Voltage line/anode for LED (+)
. . . . . <-- First pin is NC, other pins are ground/cathode (-)
LED: 1 2 3 4

When an Infinity board is running fine, there should be voltage running across each of these pairs, probably 3.3v is the rated voltage for the FrontX LEDs. But my point is that if these points still have the voltage going across them even if there's not a header, it should be possible to work out what the LED code would be if the board was a LanParty just by using a DMM across the points, and finding out which LEDs would be turned on by whether voltage is being supplied to them.

That all doesn't make much sense, but if you work through it you can see that it would make it a lot easier to figure out what's wrong with all these Infinities, whether they're actually dead (all 4 LEDs) or whether something else is wrong, which would be another combination of lights.

Can anyone confirm/deny this working? All it needs is for someone with a working Infinity to slap a multimeter across the points and see if the voltage is being supplied when the computer has POSTed, when by rights all 4 diagnostic LEDs should be lit.

Thanks for reading ;)

Nice idea. I already wondered if it would work to solder some SMD leds where the onboard diagnostic leds would be... there also should be a measurable voltage.

Maybe, in case there's no other user wanting to test it, I would fire up the spare infinity laying around here ;)

Cheers mate, you'd think that more people would be interested in this if it stops them having to keep RMAing their Infinities. I guess if it works people might be bothered to try it, but in many cases RMAing is the easy way out, even if there could be a very simple solution :rolleyes:

Yeah. And then, later muttering about the bad quality, DFi s**ks etc... cannot understand what going on with those people...

They don't want to be helped infact, they only want to spread their uninteresting crap 'bout DFI...
