*Got it fixed, thanks. Had to set OS power option to Balanced.



I OCed my intel i7 4790k a while back to a stable 4600 hz a while back and both the voltage(while using offset voltage) and core ratio would throttle when necessary. But somehow something got changed and I noticed that the voltage was staying constant and the cpu was constantly running at 4600.

Does anyone know what I need to do to allow the CPU frequency and the voltage to throttle down when necessary? It's on adaptive already.


Also, hi I'm new. Always found this site helpful just never thought to sign up until recently.




And here's the setup:
CPU: Intel Core i7-4790K 4.0GHz Quad-Core Processor
CPU Cooler: Noctua NH-D15 82.5 CFM CPU Cooler
Motherboard: Asus MAXIMUS VII HERO ATX LGA1150 Motherboard
Memory: G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1866 Memory
Storage: Crucial MX100 256GB 2.5" Solid State Drive
Storage: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: Gigabyte GeForce GTX 970 4GB WINDFORCE Video Card
Case: Fractal Design Arc XL ATX Full Tower Case
Power Supply: EVGA 850W 80+ Gold Certified Fully-Modular ATX Power Supply
Optical Drive: Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer
Operating System: Microsoft Windows 8.1 (OEM) (64-bit)
Wireless Network Adapter: TP-Link TL-WDN4800 802.11a/b/g/n PCI-Express x1 Wi-Fi Adapter
Case Fan: Noctua NF-A14 PWM 82.5 CFM 140mm Fan

If you want it to down-clock when idle then Adaptive in the bios is the correct setting. I'm not familiar with AI suite, but your power plan settings can keep the processor from down-clocking when idle. You could switch to Balanced or go into the Performance advanced settings and change the minimum processor state. The Balanced default setting for this is 5% I think, depending on your operating system (and assuming we are talking about Windows here).

Both Asus AI Suite 3 and power settings in the control panel are set to High Performance.


That's kind of another question. I've been using AI suite to OC most of the time because it's pretty handy. I'd like to just start at the base and do it right from the BIOS but it (Asus MAXIMUS VII HERO mobo) doesn't seem real clear.

I'm relatively new at OCing fyi. I've done research and am more or less comfortable, I'm just still afraid to break something.

Hmm, just did this but it didn't change anything. Still 4600 at 1.232 volts with nothing but Mozilla and CPU-Z up.




I forget what this is but I'll go check.

Ok so I reset both AI Suite and my BIOS settings to default and then did nothing but set the core ratio in the BIOS to 46x and turn adaptive on and still have the same thing happening. 95% sure Speedstep is on since the only thing in the BIOS I saw with that word in it was enabled. I'm confuzzled. Power settings are on performance but I set Minimum Processor state to 5%.



Not really. It's just an OCing interface from the dekstop basically. Which I just now set back to default and haven't touched since.

I mean it's not THAT big a deal since I can get it to hang around 1.23v with offset voltage but it'd be nice to take as much stress off it as possible and also just know what's causing it.



EDIT:
Wow lol. I just changed the OS power option to Balanced and that fixed it. Didn't try that since I thought just changing the 'Minimum Processor State' in advanced power options would be all that would have an effect on something like this and I remember reading when I initially OCed to set the power option to Performance(I forget why). I guess there's some other setting in there.

Thanks for all the help and quick replies though. My first post here and you guys were much more helpful and snappier than any thread I've made on OC.net
