I am experiencing a strange issue while playing Sins of the solar empire rebelion.
The PC shuts down with CPU debug light on motherboard lit up, I can't tell what is causing this, the event happens roughtly after 15 mins after I start the game just when larger battles start happening, I have a fleet composed of 1 capital ship and 10 light frigates attacking a nearby Ice planet to colonize, first I send my capital ship and then the frigates, as soon as they arrive the PC shuts down, I decrease my settings anti-alliasing and texture filtering and now a minute of actual battle and again shutdown.
I had a laptop before one about 8 years old, it's much weaker in terms of hardware, than my PC now, and I could play the game for hours, so I don't really think my PC is too weak for the game.
My PC is overclocked, so I thought, that might be the cause, so I ran Cinebench R20 and Unigine Heaven both for 1 hour to verify that everything is stable, those two hammer CPU and GPU harder than any game, so if 1 hour of that proves stable, I can safely exclude stability issues.
I also played Tropico 6, COD Modern Warfare and a bit older AC Black Flag, all on highest possible settings, and everything worked well, well except AC but that game has crashing issues since many other people reported them.
These games are much more demanding than Rebelion, so again that confirms my stability.
During tests with above torture test programs I monitored temps and voltages accross the board:
CPU: 85-90 C
VRM: 50 C
PCH: 40 C
Ambient: 20-25 C
Vcore: 1.4000 (no flactuations)
VSOC: 1.20-1.21 (BIOS setting: 1.2)
VRAM: (1.45-1.46) (BIOS: 1.45)
12V: 12.0000 (no flactuations)
According to above messurements, there is no overheating (I mean the CPU temps are not ideal but are safe (Tmax for my CPU is 95 C), and I have the stock cooler), however, these are the tests, they are designed to push components to their limits, I have RGB lihtning on my MOBO, which are set to imitate CPU temps, they change from Green to Blue to Red as temperature is climbing, during playing of Rebelion the lights were always blue, indicating that CPU temperature was not above 65 C. (the point when lights turn red), also my PSU is not strugulling to deliver necesary power, since all voltages are quite stable.
This leaves my with only one answer, maybe the game isn't compatible with my particullar config, bellow I will post the specs, so my question would be, does anyone else experience the same issue?
CPU: AMD Ryzen 5 3400G with VEGA Graphics (used)
4.1 GHz overclocked @ 1.4 v on CPU all core
1.7 GHz overclocked @ 1.2 v on SOC / GPU
2 GB VRAM allocated to GPU
RAM: Corsair Vengeance RGB PRO 3000 MHz 2x8 GB
Running at max supported 2933 MHz @ 13-15-16-28 1.45 v
MOBO: MSI B450 Tomahawk (7C02v1D)
PSU: Corsair CX550 550W
Monitor: 1920x1080 @ 60 Hz
all connected to UPS to protect against Vdrops and surges.
If any more information is needed I will provide them, just want to play the game.
