Hi!
It is my first time to do OC after I built my first desktop.
CPU: PhenomII x3 720BE. (default 200MHz x 14 = 2.8GHz)
mobo: ECS 790GX, which should be good OC ability according to this review: http://www.guru3d.com/article/ecs-a790gxmad3-socket-am3-ddr3-motherboard-review/1
Heatsink: Sunbeam CR-CCTF 120 mm Core-Contact Freezer CPU Cooler W/TX-2
http://www.newegg.com/Product/Product.aspx?Item=N82E16835207004
RAM: G-Skill DDR3 2x2G.
GPU: HSI HD4850 512M
PSU: OCZ 550W
I used the AMD overdrive 3.02 following the instructions.
I only increased the multiplier to 16 (3.2GHz), with the CPU voltage unchanged (1.325V). Then run the Small FFT test in Prime95. The system just shut down after 10 mins! I was monitoring the temperature, the core temperature was only 31C when it shut down!
I then ran the same test with everything in default setting. (200MHz x 14 = 2.8 GHz) However, the system still shut down after 10 mins!
Did I get a defective CPU? How can I make sure it is the CPU's problem?
Can I RMA it to newegg with this reason?
Please help me, thank you very much!
