OCZ Technology – a well-known vendor of computer components, such as memory modules or coolers, designed for overclockers and enthusiasts – said it would recall its Ultra 2 thermal compound because it did not meet declared specifications. Apparently, the thermal grease contained no silver, even though it should have 25% of silver by volume and 70% by weight. According to the statement issued by the company Friday, OCZ does not manufacture Ultra 2 thermal compound in house, but it is provided by a foreign manufacturer with certain specifications. Previous independent lab tests conducted at the request of OCZ have shown that the silver compound content in Ultra 2 is 25% by volume and 70% by weight.
In response to an article published by OverClockers.com, OCZ has submitted another batch of Ultra 2 to a third party for extensive lab testing. This independent lab report shows that the most recent batch of OCZ Ultra 2 indeed contains less than 1% silver by volume. While simultaneously the company also received lab reports from an outside source indicating the silver content to be 30% by weight. This lead the firm to the conclusion that recent batch or batches of OCZ Ultra 2 from their supplier did not meet the agreed specifications. "We accept full responsibility for these problems and we will be seeking legal action against our supplier," spokesperson from OCZ said.
