Please excuse the belt fed information: I kept a log this time as I was testing it all.
PCI1 connected only
Blue screen clock_watchdog_timeout
Possible faulty 1xRiser as it's returned two BSODs
(clock_watchdog_timeout)
(video_scheduler_internal_error)
and some really bad graphical errors
Tried on a different graphics card
-same graphical error
Replaced riser, works OK.
*random tangent* Scanned malware just to rule out - nothing found.
Individual card test: Boot up? Claymore work? Crash?
PCI 1 working with a different riser.
PCI 2 (express) working
PCI 3 working
PCI 4 eventually working - replaced the usb cable seemed to do it.
PCI 5 working
PCI 6 - no spare riser, so put the suspected DOA back in to test. No bad graphics.
Took a few minutes and a couple of restarts to sort itself out. Get BIOS screen details and boot up but as soon as it goes to windows, it's goes black.
Left it - within a minute restarted. Got back to the username screen, then black screen no signal.
Left it a minute, it restarted again but this time booted to the recovery screen. Booted into safe mode. Goes to Desktop. Shows 480 in Device Manage so rebooted.
This time made it to the desktop! Wahoo... too early. Black screen "no signal". rebooted itself. BSOD Video TDR Failure (atikmpag.sys). Reboot. Recovery. Restart. BSOD Video TDR Failure.
Move Riser to CARD 4, remain in PCI 6. Boots to Desktop. Black screen, no signal. Must be a dead riser i thought
Connected working riser; CARD 6 to PCI 6. Worked OK. Thank F
Tried a new USB cable (long shot?) and it suddenly works
Most needed a minute to sorts itself out, then a reboot.
Now I'm going to connect cards 1-6 and test.
All display as working in device manager.
Successfully opened Wattman on all of them.
Miner test - All cards displayed. All cards hashing.
erh-ma-gerd... I don't want to start dancing too early... but it's looking promising
The 480's are hashing about 580-590 each (XMR) unmodified / factory settings. Anyone got a good flash/setting start point?
