i7 4770K msi z87 g45 bios OC question?

post #1 of 3
Thread Starter 
2 questions. i7 4770k @ 4.4GHz with msi z87-g45 mb ver. 1.6 bios. Right now my multiplier is at 44. It's giving me a stable OC at 4.4GHz, but my speed never changes it's always at 4.4. I have the setting in the bios set to dynamic but still no change. Is there a way to keep it at 4.4 and set the turbo clock higher? Is there a way to set the bios to let it throttle down during slow states and throttle up to a specific turbo speed when lets say prime95 starts up? I cannot see a specific setting In the msi bios for the turbo clock multiplier setting. My goal is to have the cpu range between 3.5 and 4.4 or higher but just can't seem to get it to happen. Any help would be appreciated thanks.

Why do you want a variable clock? as fare as I know, the turbo function is only used for ppl who dont OC, so they get more power from a non OCed chip. Since you have OCed to 4.4ghz, I think that turbo is automatically disabled.
Turbo is used to get the standard 3.5ghz pushed to 3.9 when needed, since you gone higher, it wont be a good idea (if even possible) to use turbo.
What is your Vcore for 4.4? auto?

I would just forget about the turbo options since you are OCing manually..
I also seam to recall that it is not a good idea to use the power saving features while running stress tests.. it might pump too much current through your CPU and worst case, kill it.

What monitoring program are you using? You wont see the clock (4.4ghz) drop, but the Vcore will.. (idle / load)

*Edit*
You might wanna read this guide: http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics
Loads of good info there smile.gif
I would just leave it as it is right now (unless you wanna go higher) but I wouldnt worry about the turbo / non variable clock.

I used turbo boost core multiplier to overclock my CPU.

First I used the core multiplier (non-boost one) to overclock my CPU.
Then tried Turbo Boost core multiplier and leave the base multiplier at stock.

I don't see anything wrong altering the turbo boost multiplier to overclock your CPU.

May be able to set the non-turbo CPU multiplier to e.g 35X and the Turbo multiplier to anything you like (probably 43-45x) not sure.
