This made installing non-standard or non-certified heatsink solutions a risky business. OEM aluminium heatsinks typically provided small thermal tolerances so the improper application or absence of a thermal pad or thermal grease, or operation in high room temperatures, could lead to some Socket A CPUs overheating and crashing. Chipsets In practice third party chipsets were heavily favoured by motherboard manufacturers. Stability problems and compatibility quirks abounded from manufacturers not following chipset designers' guidelines which in turn caused lasting damage to AMD's reputation despite AMD having nothing to do with the poorly realised hardware. Third-party chipsets include the nForce, nForce2, and a large number of VIA K-series chipsets. See also List of AMD microprocessors References AMD sockets
