Known issues:

  • Fake cache.

    The cache mounted on the motherboard may be fake. Soldered DIP-chips "WRITE-BACK" markings and traces that go nowhere are often hints that the cache is fake. Soldered DIP chips can usually be removed and replaced by real cache chips on sockets to get functional cache.
