Also known as:

  • Amptron DX-9700 VER. 1.0
  • Mach Speed G486VIP

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.

  • Proprietary Cache Slot

The motherboard has a distinctive, non-standard cache that can affect compatibility and performance. The cache slot might resemble a familiar slot type, such as an Intel COAST slot or another common design. However, it is not compatible with these modules. Connecting an incompatible module may lead to irreversible damage to the motherboard. Exercise caution to prevent damage to your hardware. It is likely that you are dealing with a PCChips motherboard.
