How long to test overclocking?

[absic]

Hi again,

looking at the pictures you posted it shows that your CPU Core temps hit 61.5C according to AMD Overdrive and 62C in HW Monitor this is at the top end of the specs for the CPU and you need to be careful not to run at that sort of temperature for any length of time.

Although 55C is OK it is still a little too warm IMO. As an example, when  I ran my 1090T overclocked to 4.0GHz my CPU Core Temp never went above 35C-37C, mind you, I am using a Noctua NH-D14 cooler. I have now pulled it back to stock speeds and my current temps are about 20C (ambient is also 20C).

It might be an idea to turn the Fan on your Cooler up to full to try and bring the temperature down a bit more. I would aim, as I said previously for a working temp of around 38C-42C or lower if possible.

This was step one back; with lowest fan speed. And it wasn't with Prime95, after 25 minutes AOD stability test.

What temps do you get if you turn the fan speed up?

The cooler you can keep your CPU the better, especially when overclocking.

50-51C

I'll use fan speed, but I want to test with lowset speed to be sure better

I especially use PC for video editing / rendering. So I did a test with Sony Vegas 64 bit

Video was 1280 x 720 uncompressed with 48khz wav sound

Sony Vegas project is 1920 x 1080 - Progressive 25 PAL

Video total time : 2:00 min

Render settings : Main Concept AVC / AAC mp4

8500 - 5500 (2pass) - Progressive - 1920 x 1080 - Deblocking filter - 48 /512 AAC

with standart CPU 3400Mhz

render time : 15:31 min - temp. around 54.5C

with 3825Mhz

render time 13:25 - temp. around 56.5


difference is nearly 2 min.

with lowest fan speed.


And I'll test with Crysis game.
