C'est normal que tu ne trouve pas OCZ vu qu'il n'existe plus comme entité propre, ça a été racheter par Toshiba en 2014 (il me semble sur l'année je suis pas certains) seul la branche SSD garde le nom OCZ d'où le fait que sur le site il n'y est que ca.
Il me semble que légalement toschiba n'est pas expressément tenu de respecter les anciens engagement de garantie sur des produits qu'il ne fabrique pas, donc les anciens SSD c'est bon, la RAM c'est selon leur bon vouloir.
Donc voir directement avec toschiba je pense
Texte original:
OCZ Technologies (OCZ Technology Group) was a leading edge producer of performance computer products – at first RAM memory and power supplies for gaming and overclocking, then they took on SSD solid state drives and abandoned the RAM and power supply business. In 2011 and 2012 OCZ bought SSD controller designer Indilinx, the R&D department of Oxford Semiconductor and the Israeli software firm SANRAD in an attempt to become a vertically integrated SSD development company. However, in 2013 OCZ’s revenue fell sharply and they took out an expensive credit line from a venture capital firm. They were unable to meet the obligations of their loan or meet their financial filing requirements and entered bankruptcy proceedings at the end of 2013. Some assets of OCZ Technologies were sold by the creditor to Toshiba in January 2014, and were renamed OCZ Storage Solutions, an independent subsidiary of Toshiba.
Since Toshiba purchased the assets only and incorporated a separate company, the ‘new’ OCZ has no obligations for warranty for previous OCZ customers. The ‘new’ OCZ has agreed to honour warranties for a select group of higher end SSD models (Vector and Vertex), and they disclaim responsibilty for all other products, including all RAM and Agility, Octane, Petrol and Solid SSD models. Below is the statement from Toshiba regarding warranty and support (emphasis mine).
