Also known as:
- Octek HIPPO DCA2 486
Known issues:
- Leaky Ni-Cd clock battery
The Ni-Cd battery may be leaking, risking damage to PCB layers & nearby components. Promptly remove the battery & clean corrosion/alkaline salts from the board. Use white vinegar to dissolve salts, but exercise caution as vinegar can corrode exposed metals. A thorough examination & repair may be needed.

- 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 boards have no traditional cache.
What is DynamiCache (ED-RAM)?
From the manual: A high speed memory that operates at 15ns rather than 70ns.
The two outside SIMM slots are for regular FPM, the other two are for DynamiCache.
