Uncore Clock stuck at 800 MHz

[luckyboy]

With f3 bios, when pc in idle, cpu uncore is 800 MHz, under load - 3700 or 3900 MHz. Now with f4 bios always is 800MHz?!? If I enable xmp profile, uncore clock is always 3500 MHz, even in idle. With f3 I do not have this problem. Any new bios for g1.sniper z87 - beta or moded?

Yeah quite odd, have you cleared CMOS?

I cleared cmos when updateted to f4 before month. Downgraded to f3 and now is ok.
Any differences between G1.Sniper Z87 - F4 -15.Aug 14 and G1.Sniper Z87 - F4 -21.Nov 14?

Good question, you can use comp to see if there is any difference.
The better question is why have you updated at all, rule of thumb - if it works, don't fix it.

So the F4 BIOS seems to lock the Uncore/Cache frequency at 800MHz? What is the Uncore/Cache multiplier set to in the BIOS? Auto or a specific value? That is with XMP enabled and disabled, any difference in the Uncore/Cache multiplier setting?

Auto. With f4 bios, if I enable xmp, uncore is 3500 MHz. When xpm is disabled - 800MHz. With f3 all is ok. Uncore is 800 MHz in idle and 3900MHz when run some benchmark or playing games.

I can't understand, why after any bios update and restart pc, when Windows loaded, I see Balloon Notification about ''new driver was installed''?

Click the balloon and see which driver it was.

Re: Uncore Clock stuck at 800 MHz

One of them was network driver. Others...I think sata driver and something PCH, I'm not sure. But before and after bios update network driver version is the same, according device manager (screenshot below)?!?

Re: Uncore Clock stuck at 800 MHz

You got some uninstalled devices (Other devices) what are those?

Re: Uncore Clock stuck at 800 MHz

This is pci simple communications controller and ''question mark'' is because I do not installed Intel Management Engine Interface driver. This driver is useless for me.

Re: Uncore Clock stuck at 800 MHz

Your board's features will not all function correctly without the Intel Management Engine components. Some of those features are on the chipset.

Your board's BIOS has Intel IME firmware contained in it. Without the IME software, the IME firmware cannot communicate with the board and chipset correctly.

You can set the Uncore multiplier manually to whatever value you want, normally the same as the standard speed of your processor, 35/3.5GHz.

Re: Uncore Clock stuck at 800 MHz

I thought Intel Management Engine Interface driver is not important for home users, but after your info, I will install. About uncore, I decide to stay with f3. Thank you parsec :)
