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 DIP-chips and no jumpers to set the chache size. Cache functionality can usually be restored by installing proper chips, jumpers and a BIOS update/mod.
Notes
The CPU socket is not a full Socket 3, it lacks the outside rows of pins used by the Pentium OverDrive.
