Notes

The board uses ISSI IS61 LV 256-15N cache chips. Emphasis on the LV, they are run at 3.3V. 5V cache chips may not be stable on this board.

SRAM cache chips are powered by the secondary CPU voltage regulator, high CPU load can cause cache upsets if voltage regulator is overloaded.

Linear voltage regulators have poor contact with heatsinks, prone to overheating without direct airflow or replacement.
