Default Re: CPU Problem

what would be the safest cpu temp of 3.2Ghz and 3.7Ghz? coz i think atm my cpu is at 3.2Ghz my temp is at around 40C at full load using prime95 but i havent tried it more than an hour yet.

You are fine. On load, It should be at max around 70. Normally, 78 is the CPU heat limit, If it exceeds that, your computer will shut down.

While the i5 and i7 cpu's use a different chipset, P55 vs. the X58, they still operate quite simular. You can use this guide to help you, i7 Overclocking Guide. Print it out so you have it available while your looking at your bios.

how many hours do I have to stress test my cpu after ocing it?

if I enable xmp is it safe though? why it did decrease the cpu ratio to 17 instead of standard of 20? also if I leave the BCLK to 133 the memo speed is still @ 668mhz.

Do not enable xmp if your overclocking. Set your memory speeds and latencies yourself.

The length of the Stress Test depends upon what program your using.

Read the whole Guide, numerous times if needed.

Default Re: CPU Problem

for some reasons when I tried to change the DRAM the max is 1333mhz. I changed the BCLK to 160 and the CPU ratio is @ auto after changing BCLK and DRAM to 1600mhz then the clock speed of the cpu is @3.2Ghz it doesnt stay @ 2.66Ghz but I wonder if its safe to stay @3.2Ghz because i didnt touch any of the voltages.

If you read the guide you would know that the 1333MHz setting is a ratio number, 1333=10. And you would know that the
BCLK x DRAM Ratio = The memory speed
160 x 10 = 1600

Auto equals the Default Setting. In this case the Default CPU Ratio is 20.
BCLK x CPU Ratio = CPU Speed
160 x 20 = 3200

Above you said 1333mhz was the max. value. Do you have this setting at 1333 or 1600? 1600 equals a ratio of 12
160 x 12 = 1920
Your computer probably won't start at this memory speed

Run a stress test, if it passes and your temps stay within the safe limits then your fine.
