Fluctuating CPU Frequency

[froot]

My Asus software does "spike" to the extremes now and then. In the BIOS I find it to be accurate though, so not sure why it's like that - apparently it's notorious for being useless.

I also use HWMonitor and it works well.

If you are running an MSI MOBO then you can disable the following;

Limit CPUID Maximum
Power Technology
C1E Support
OverSpeed Protection
Spread Spectrum

All these are used to keep the CPU usage down in IDLE and ramp up the Mhz when you play games or software that generates high load.

The drawback of this is, when you are running a game/rendering software that will increase the voltage/heat on the CPU this will kick in and lower the overall performance.

However this is your choice to disable. Should you disable this it will always run at the full Mhz which will consume more power and possibly shorten the life span of the CPU.

If you want a good read through on overclocking, i suggest going here :

Even though I disabled SpeedStep, C1E and Turbo Boost in my Bios, CPUZ still shows the frequency at 1.6Ghz when the PC is idle..

Any ideas?

One more thing, the AI Suit that comes with Asus Motherboards - is its CPU temperature sensor reliable? I ask this because when I access my BIOS, the CPU temperature reads about 50 - 60 degrees Celsius, but when I boot into Windows, the Asus software says its at 37 degrees Celsius..

I think its safe to assume its an Asus motherboard

I just have to mention this - I ran Prime95 blend test, and within 2 seconds my CPU (2600K for those not following) hit 80 - 90 degrees on the stock cooler. After I picked myself up off the floor, I realized that I need a new cooler and some Arctic Silver.

Any good coolers to recommend within the R650 mark? I had a look at the Corsair H60, any good?

Thanks

yes those stock coolers are pathetic... way too small...

Im running a hyper-212+ and i see 60 degrees on my hottest core while running intelburntest, but you could probably get it lower with something more expensive, i.e water cooling... not sure how good the H60 is though

I also thought about the 212, along with these:

Thermalright Venomous X
Coolermaster V6 GT
Antec KÜHLER 620 H₂ o cpu water cooling

Anyone own one of these?
