I jut bought a dell alienware x51 r2 from ebay. The seller update the system to windows 10 x64. I hawe a Asus VG248 Monitor using with the system. First of all after a clean windows install when traying to install AMD video card the system is freezing let me to do nothing. I trayed to install all AMD drivers i could found on but with no answers. On some forum i found out that for this video card is recomanded a 400 - 500 w power supply, but my Alienware X51 R2 is coming with a 330 w power supply, is enough ? On other forums i found out hat this problems may be fixed with a GPU Bios update, but how ? where i can find out how to do this, and this is the solution ?
My system bios is up to date, and it's working fine with Intel 4600 onboard video card, but any intention of using / installing AMD Radeon R9 270 is going to crash my system.
Please let me know if there is a solution for this problem or should i return my recently purchase.
A 330W power supply seems quite low for your system, i expect this is causing the instability. I would recommend contacting Alienware for support with this to ensure it's compatible.
