Also known as:
- CONCORD OFFICE AUTOMATION INDUSTRIAL (HK),, LTD. COA-921
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.
