|"I don't want to overclock my computer"|
Disappointing that you refuse to overclock. You're losing out on a lot of performance by not taking advantage of the full potential of your CPU, motherboard, & RAM. Whatever. You should still manually configure the BIOS settings. Use all the above settings but change these two:
Ratio CMOS Setting = 8, change to 8.5
FSB Frequency = 400MHz, change to 333MHz
"I am sad to hear that extreme plus series aren't good because I have it"
All you had to do was google up the reviews:
"right now my country is in the summer and it is way hot"
It's summer where I am too. Right now, it's 86F (30C) in my room. My overclocked CPU is at 33C, HDD is 39C, & my passively cooled GPU is 56C. And I have zero case cooling fans, just the top mounted PSU with it's 120mm exhaust fan. It's all good here.
