I have two rigs currently, that are all 3080ti’s same setup of Ryzen 3 1200, 8gb ram
Rig one is 4 MSI gamix x trios and 2 EVGA FTW3 Ultras
Rig one has 1x 850W PSU + 2x 750W PSU
Rig one runs at 470MH/s @ ~1700w
Rig two is 5 EVGA FTW3 Ultras and 1 MSI Gaming X Trio
Rig two has 3x 850W PSU
Rig two runs at 498MH/s @ ~1700W
I have no idea why, as they are almost identical, but I cannot overclock Rig 1 the same as I overclock Rig 2, as soon as I bump up memory to +2000 or more it just crashes the whole rig, LA shoots up, and crashes.
Whereas rig 2 runs at +2700 memory and no problem whatsoever.
Can someone maybe shine a light on why it is like so? Is it possible because of the insufficient PSU wattage? Or wiring? Risers are powered by molex to 6 pins, and cards are powered by two direct 8pins to the PSU with one slot daisy chained off the other.
