GA-Q87M-D2H with i7 4790: Turbo Ratio stuck on 'Auto'
« on: June 04, 2016, 09:17:34 pm »
Hi everyone,

I built a new computer with the following components:

Motherboard: Gigabyte GA-Q87M-D2H
Revision: 1.0
Bios: F7 (upgraded from F4)
CPU: Intel i7 4790 (non-k, Haswell Refresh)
CPU-cooler: Gelid Solutions Tranquillo rev.2
Memory: 32GB of Crucial Ballistix DDR3L-1600 UDIMM 1.35V 8-8-8-24 (BLT2C8G3D1608ET3LX0C)
SSD: Intel 535 (240GB)
PSU: Corsair AX760

I upgraded the BIOS because of the Haswell Refresh CPU. When setting the bios up for that CPU I found the "Turbo Ratio" stuck on "Auto". With that, the 1~4 Core Active is stuck on 40-40-39-38. I would have liked it to be on 40-40-40-40. How do I get it to do what I want?
I prefer the BIOS over a program. I am not familiar with EasyTune and can not test it myself right now, but can someone confirm if it would work with my (or similar) cpu?

I hope someone has an answer for this question.

Non-K your options are going to be limited and the Turbo boost settings only apply when the CPU is under load.
Check in Windows, do some kind of stress test or play a game to see what the cores actually run at.

Hardware monitor will show you the core frequency whilst you do the above.

Hello ElectroStingz,

Thanks for replying. I knew that non-k would be limiting, but not this much. On my other machine I have the i7 4770 non-k running fine at 39-39-39-39. The motherboard is an Asus z87-a though.
I thought that the GA-Q87M-D2H would also allow me to run the turbo on the highest ratio since the feature is  mentioned in the manual. It is mortifying that my 4790 is running slower than my 4770 (3792MHz (38x99,79MHz) vs 3978MHz (39x102MHz); 186MHz slower) when it matters  :-\
Note that I am not whining about a non-k cpu not being the same as a K cpu but about unnecessarily losing about 5% of potential running speed that it should be able to.

Are you saying that my only hope lays within software in Windows?
I was holding back on installing windows 7 because I have an OEM version (locked on motherboard) and because I am still waiting for some hardware to arrive. It seems I need to install the OS as trial to test it.

Yes software might overcome your problem, give the Intel XTU software a try but Intel chipsets also define your overclocking abilities.

Z87 = supports overclocking.
Q87 = no overclocking.
