Beh, si è rivelato un affare. Il prodotto funziona perfettamente e visivamente era pari al nuovo , si poteva notare solo dal connettore che la ram effettivamente era gia stata inserita in qualche scheda madre. Per il resto non sono un professionista e non so dire se questa ram vada meglio o peggio di altre marche. La consiglio per rapporto qualità / prezzo. ### ⭐⭐⭐⭐⭐ Good way to expand your RAM *by X***X on Reviewed in the United States on 2 January 2020* And do it on budget. ### ⭐⭐⭐⭐ Ojo porque es RAM RDIMM *by I***O on Reviewed in Spain on 28 June 2018* Gracias a este producto yo me he enterado que hay dos tipos de ram, RDIMM (como ésta) y UDIMM. Comprobadlo antes porque en mi caso resultó no ser compatible. Lo he tenido que devolver y como siempre UN DIEZ para el servicio de atención al cliente. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/397364971-crucial-ct8g4rfs8266-8-gb-ddr4-2666mt-s-pc4-21300-cl19](https://www.desertcart.tn/products/397364971-crucial-ct8g4rfs8266-8-gb-ddr4-2666mt-s-pc4-21300-cl19) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-24*
