problem with Z87X-OC (poor Gigabyte BIOS and software?)

[rcarlos243]

I have this motherboard (Gigabyte Z87X-OC F9c BIOS) and I am trying to overclock the CPU through base clock with no success.

my complete specs:

CPU: Intel Xeon E3 1230 V3 4c/8t haswell
MOBO: Gigabyte Z87X-OC
RAM: 8GB Gskill TridentX 2400 CL10 1.65v
storage: 1x ssd, 2x hdd
GPU: MSI GTX 780 3GB OC
PCIe card: mini pcie to PCIe adapter (for my wifi card Killer N-1103 802.11n) it is installed on the 4th PCIe slot
PSU: Seasonic X660 Platinum
cooling: 2x Corsair H110 280mm AIO Liquid Cooler (1x for cpu and 1x for gpu)

my cpu temp never go above 54c under stress test using AIDA64.


Thing I tried:
-disable XMP for memory
-disable all power saving feature for cpu
-manually set the voltage for the cpu, ram, etc... (cpu vcore, PCH, System Agent, ram
-disable all unnecessary stuff i don't need on the BIOS (like the lan controller and audio)

The problem:
Whenever I try to increase the base clock even at the smallest amount (like 101 Mhz) under the BIOS the computer wont boot. If I do it on WIndows using gigabyte easytune software, the computer would lock up.

I also noticed that there seems to be a problem with regarding maximum multiplier for turbo on all cores. The default turbo for all core for my cpu is x35 which is 3.5Ghz but there is selection up to x37 which should make the cpu go 3.7Ghz. Changing the multiplier for turbo on all cores from x35 to x37 has no effect (the cpu still runs at 3500Ghz). I tried it both through BIOS and Gigabyte Easytune utility but both doesn't work.

I research and found that other users presumably using other brand mobo if they set the multiplier to x37 it actually works: http://diybbs.zol.com.cn/69/231_680262.html

also proof that my cpu could be overclocked through base clock: https://translate.google.com/translate?hl=en&sl=auto&tl=en&u=http%3A%2F%2Fwww.computerbase.de%2F2013-10%2Fintel-xeon-e3-1230-v3-test%2F7%2F

Is not the board it is the chip even though 1 or 2 people have gotten it to overclock it is not supposed to be and overclocking chip. If you wanted to overclock it is better to buy a chip that can do it like a k series.

I tried my cpu on another motherboard (my friends Asus Z87-A) and I could actually use the available max multiplier selection (x37) for all cores under AIDA64 stress test. I also tried raising the base clock to 105Mhz (with x37 multiplier) to raise the cpu speed to almost 4Ghz on all cores and it works totally fine even on prime95 or AIDA64.

poor Gigabyte BIOS and software?......

BIOS must be modded to have all core available at max multiplier (x37) for non K CPU.
I can do....let me know.

For increasing base clock above 100 ,you should increase also CPU Vcore (maybe other voltage as well).
To do in Windows the best is GTL (GIGABYTE TweakLauncher).

Edit:

Bellow is modded F9c with max multi for non K CPU's:

Either others mobo vendors do not have application to displaying what you mention....."like my onboard lan and sound being turned off and my memory already set to xmp and other stuff like uefi, fastboot, etc..."
