Before we go any further what’s the part number of your motherboard? This specific dual 360mhz processor module is only designed to work with later octane motherboard revisions!
Also what version of Irix are you using?
Please read the second paragraph of the processor section:

If you are using a later board than the error literally means it’s often failed RAM, a bad driver for the hardware, or a hardware failure. Normal tlbmis isn’t supposed to cause a kernel panic and crash but often shows itself as a symptom of a kernel driver bug/issue or direct hardware interface issue ( compatibility) in Irix.
