Chinese New Year had a week of holiday for us in Hong Kong. It’s great to relax for a week, playing games, sleeping and watching movies. But it’s time to go back to normal school life. For the first day, the first lesson starts from 0830 in the morning. It’s harsh for me! Why?? Because I usually sleep in about 4 o’clock every night. Bad habits right? I’ve only got 3 hrs to sleep, that’s not enough for me, perhaps I must change my sleeping time, but it’s difficult. Try la @@ not health ma…

On the other hand, for my overclocking test on AMD AthlonII x4 640 C3. I’ve finally got a testing report…

CPU 200×15=3000 @1.175V RAM 1333 CL8-8-8-22 @1.48V

CPU 220×15=3300 @1.325V RAM 1466 CL8-8-8-22 @1.48V

CPU 240×14=3360 @1.350V RAM 1600 CL9-9-9-25 @1.48V

CPU 250×12=3000 @1.250V RAM 1333 CL8-8-8-22 @1.48V

p.s. previously, I was not able to run 200×15=3000 @1.175V, is not the CPU problem, it was the RAM. My Team Elite DDR3 1333 CL9 2GBx2 was not able to run 1333 CL7-7-7-20 @1.48V, which causes rounding problem in prime95.

It was quite good to see that, my CPU can run 250×12=3000. Because it is much faster than 200×15, but required higher voltage and higher temperature, that was not ECO-friendly. So, I’ve chosen 240×14=3360. It was the fastest among the others and having highest memory bandwidth. Of course, it will have to highest temperature among the others, but it is not usual to run at high CPU usage. I think that my CPU can go further more, but the stock cooling is not able to handle the increased amount of heat by overclocking. If I’ve changed the cooler, I hope to use 240×15=3600 or 250×14=3500 for my maximum speed. However, I am afraid that my power supply was not able to handle the increased power consumption from the CPU. Moreover, I wonder why my relative’s computer usually blue screen. That should be the motherboard problem, but I can’t believe it. I hate to bring products for warranty😦

Later on, I will start writing the overclocking life pages…
