Known issues:

  • Fake cache

The motherboard may include a non-functional or counterfeit SRAM cache, which can adversely affect performance. Signs of fake cache often include soldered QFP or DIP-chips labeled "WRITE-BACK" with traces that do not connect to the chipset.

  • DIP chips can typically be removed and replaced with functional SRAM chips in sockets to restore cache functionality.
  • QFP fake cache chips are often not replaceable with functional cache as the PCB footprints are not chipset connected.

Notes:

The CPU socket is not a full Socket 3, it lacks the outside rows of pins used by the Pentium OverDrive.

Is cloned as Amptron DX-9300A (VER 1.1)
