I recently ordered two Z170 platforms to update two aging machines still using P55 and X48 respectively (Voyager and Intrepid in my signature). I ordered the following components:
Voyager: Core i5 6600 CPU, Gigabyte Z170X-UD5, 2x8GB Corsair Vengeance LPX 2400mhz, Corsair RM1000i
Intrepid: Core i5 6500 CPU, Gigabyte Z170-HD3P, 2x8GB Corsair Vengeance LPX 2400mhz
The PSU I realise is way over the top for the current 970 but both board and PSU were intended to future-proof the system for a high-end SLI setup potentially coming later.
I have failed an RMA for the UD5 board as it will not POST with memory in dual channel (cites a 55 error after several cycles through the early part of the POST routine), the only combinations I could get working were one stick only, then two sticks right next to each other (i.e. not in a pair of slots the same colour as they are supposed to be) - 4 slots didn't work, and neither did either set of the RAM I bought, in either of the proper channels (i.e. both black slots, or both grey slots). One particular stick didn't even seem to work on its own, so I've put that to one side for further testing when the RMA'ed board arrives.
That, however, isn't the issue that has me confused. One other issue the UD5 board has, which I originally disregarded due to this RMA, was that even with memory in one of the working configurations above, the system will only POST the first time the power button's pressed after mains power is applied. Every time the PC is to be powered up using the power button, the PSU needs to be switched off and then back on first, otherwise the POST stage will not complete (the dual 7-segment does not light up when this happens)
As a result of the RMA above, I set the 6500, second set of memory and the HD3P board up in the main PC, Voyager, so it could be properly tested before being installed in my file server, Intrepid, which would be a much more difficult machine to have stability issues with. This has none of the issues with memory the UD5 board has, and boots straight away with memory in the right place. However, although at the moment it seems to be OK with reboots, if this machine is re-powered after having been off for some time (say, more than 15 minutes) it too will not POST at first. I don't seem to need to re-power the PSU with this one, I just have to power the machine off two or three times, after which point it'll boot normally.
This really isn't something I want to be putting up with if the board is going into a server that's supposed to run 24/7. Is this a known issue with the Z170 chipset, perhaps Gigabyte's implementation of it, or do you think I have two defective boards?
Despite the boot issues, the system seems stable in windows, has been running for around 10 hours total and played an hour session of Rocket League without incident.
Bit puzzled by this one, and would appreciate any comments if anybody has seen something similar with these boards.
