Asus Z87-Pro Questions

post #1 of 3
Thread Starter 
Hi There!

I got myself a Z87-Pro and i7 4770K. I got the shop I bought it from to overclock it but when I open control panel in w8 it shows the processor is at 3.5Ghz when they said they got it to 4.5. If I use CPU-Z the clock speed keeps fluctuating. Is everything working as it should be? What is the best way to benchmark the performance of the cpu to compare it to others who are getting 4.5ghz on this processor.

Secondly, I am using USB3 and connected that to my Galaxy S4. It's taking an AGE to charge that it didn't used to on my USB2 ports on the P6T Deluxe before. Are any of the ports on the Pro suitable for faster charging?

CPU-Z does a fairly good job of showing you what your CPU is actually doing, and fluctuations are normal. Actually, look at what Real Temp shows: it's more accurate even though it's primarily a temperature monitoring program.

 

Anyway, run Prime95 for a few seconds to watch the clock go up to 4.5 GHz. This is the turbo multiplier kicking in.

I think unless you don't turn off EIST from bios and set the power to high performance from power options in control panel, Windows always shows the stock speed. But don't worry. Check it in CPU-Z and you should see the clock speed fluctuating. It will rise up when there is demand for more power. You don't need to run the CPU at full clock speed when it is not necessary.

The bottom Intel USB3 port seems to support after charging as per the manual. Not sure if others don't. I though all the ports were supposed to charge devices quickly.
