Overclock not showing in CPUz?

post #1 of 5
Thread Starter 
I have a 2500k and I managed to get it to 4.3ghz, any higher and my computer wont boot unfortunately. I'm overclocking on a Asrock extreme3 gen3 board.

I have Intel Speedstep disabled, spread spectrum disabled, cpu load line level 1 and the ratio to 43x. I haven't changed anything else and managed a successful boot.
The problem is that cpuz is showing 1.6ghz at idle and jumping to 4.3ghz at times, but when I run Prime95 it goes back to stock turbo boost speeds 3.6ghz.

Also I'm having trouble adjusting the multipler, most times when I try to change it, the only number I can type in is '5' anything else and it will automatically put in 16 for me.

Anyone know whats up?

It might have something to do with the settings. Can you list them all in detail, or even post screenshots of your BIOS? (or photos, if the BIOS doesn't offer an ability to take screenshots)

That isn't the problem. When I toggle that setting on and off, it doesn't give me the behavior that he's experiencing.

If you want a high multi when your CPU is idle, make sure you go into the Control Panel - Power Options and that you are using the Windows High Performance power profile with the Minimum processor state set to 100%. If CPU-Z is showing a 16 multiplier when idle, you are probably using the Balanced power profile.

If your multiplier is dropping when fully loaded with Prime95, go into your bios and look for your Turbo Boost power limits. There is a long term and a short term limit. Increase both of these limits significantly and then your CPU will be able to maintain the maximum multiplier when fully loaded with Prime. Many motherboards will automatically increase both of these limits sky high when overclocking just to make sure that they do not become a limitation. A CPU can only consume so much power so going too high is not going to hurt anything. The default settings are too low for maximum performance when fully loaded.
