Hi All,
I have tried out some bench marking tools on my computer and have stuck with CPU-Z as a reference for this question.
When I try the stress test with CPU-Z the program states it running at 100% load allfine and dandy.
however when i look at the task manager performance tab, i see that it jumps up and down from 100% to sitting at 80% alot along side the cpu speed changing from 2.7ghz to 1.9ghz in a second.

Funnily enough i took the laptop in for repairs and they replaced the motherboard because i also found that it couldnt hold a stable transfer to a usb or external hdd(wd 2tb usb 3.0), it would constently jump from 3.0 speed to anywhere around 50-100kbs which i believe s slower then usb 1.

I am just curious if i should question the constent cpu power changing on the newer board and if i have to worry about the transfer speed to act up again as well.
Ps i have only transfered one folder with 60gb of videos accross so far and it had a big drop in the middle of the transfer but for the most part it stayed on a gradient.

Thanks for the help:)

It's in both; the chip will protect itself, the BIOS can adjust this. 100C sounds like the heatsink needs to be removed, re-compounded, and re-installed. Is it a notebook or a desktop machine?

Your BIOS or custom utilities from the manufacturer may let you control cooling profiles. If you set a more aggressive cooling profile, the fans will be louder but you may be able to scrape out better performance.

Thanks for the advice, i did notce that as soon as the first core(dual core i7 5500u) got to 72c and second was 68c then it would drop the volts so the temp would then go down to 50. I used Real Temp to check the temps.

Im curious if thats a safety protocol in the chip or the computers bios or something.
Mainly becausemy sister has a different type of computer and it only lasts a couple of seconds at 100% because the temps go over 100c.
