Gigabyte Easy Tune 6 Overclocking
4.2GHz overclock using Easy Tune 6
Most high-end motherboards include numerous overclocking options for beginners and experienced enthusiasts. The X79-UD5 provides plenty of options for adjusting CPU and memory voltages, ratios/speeds, and timings. Their 3D BIOS is easy to use to tweak the processor to the user’s exact specifications to get the best overclock possible.
We opted to change up our typical overclocking method with the X79-UD5 and use Gigabyte’s Easy Tune 6 technology first before moving on to manual overclocking. To use this feature, we had enabled it in the 3D BIOS. Next, we opened the Easy Tune 6 application in Windows 7 and clicked on the three "quick boost mode" overclocking buttons that automatically overclocked our i7-3820 up to 4, 4.2, and 4.4GHz. We confirmed the results using CPU-Z, and noticed that the board worked as advertised by automatically increasing the CPU multiplier to 42 without adjusting the core voltage or memory timings. This is around a 12 percent increase in performance from the i7-3820’s stock speed of 3.6GHz.
Manual overclocking
The second part of our overclocking tests included manually overclocking our Intel i7-3820 processor through Gigabyte’s 3D BIOS. To do this, we uninstalled the Easy Tune 6 application and restarted the system. Then, we rebooted again and accessed the 3D BIOS to manually configure the CPU clock ratio, CPU voltage, and processor per clock ratio. Ryan wrote an excellent tutorial for overclocking the i7-3820, which helped me in learning the ropes to get the most out of the LGA 2011 platform. Here’s a quote from Ryan’s review that illustrates a key change in the overclockability of the i7-3820:
"…overclocking on the Core i7-3820 is a bit different than with any other Sandy Bridge processor out there. Because it is not fully unlocked, the multiplier is limited to 43x, about the same as the non-unlocked Core i7-2600. Unlike the original Sandy Bridge though, Sandy Bridge-E allows us to use "straps" or bus speed multipliers that still operate with the 3820."
I followed Ryan’s advice for adjusting the strap options to 125MHz or 1.25x, which helped me overcome the CPU multiplier limitations. I also increased the CPU voltage to 1.4v to help improve the stability of our overclock.
I left the CPU multiplier at 37x, and concentrated my efforts on configuring the CPU clock and processor per clock ratios. I adjusted the processor per clock ratio to 1.25x, and reconfigured the system memory multiplier to 1000MHz to ensure the memory timings were not a limiting factor in getting a stable overclock. After rebooting and confirming our overclock with multiple runs of Cinebench 11.5, I was satisfied with a 4.625GHz overclock on our i7-3820 CPU. I’m sure with a higher-end cooling solution and more BIOS tweaks, we could have gotten the processor closer to 5GHz or more.
CPU Speed | BCLK | CPU Multiplier | DRAM Frequency | DRAM Timings | CPU Voltage |
4.625 GHz | 125 MHz |
37x |
1666 MHz | 9-9-11-24 2T | 1.404v |

I’m going crazy with this
I’m going crazy with this setup and hope somebody can help me. I7-3960X with 8 sticks of 8GB Crucial memory CT102464BA1339 stuffed into an X79-UD5 Everything is supposedly compatable, according to the HCL lists, and all the techs I’ve talked to from all three companies agree that it should work. Plenty of power, 1000W Cooler Master power supply, all the plugs ring out active with a volt meter. I’ve played with memory timings until I’m blue in the face. I’m on my third motherboard because GB thought there might be a problem with it, I’m on my second set of RAM, and on my second processor, still with the same results. Not matter what I do, if I populate more than DRAM-1 and DRAM-2 it goes into a rapid beep and won’t even load the bios. Populating only 1 and 2 allows me to get into the bios and try to tweak the voltage and timing settings, but they always seem to cause an issue when it boots even if I’m adjusting the timings to a slower rate than what it was from stock. I’ve been building computers for 25 years now, and have never had this much trouble.
Ron, did you ever resolve
Ron, did you ever resolve this? I too have a maxed-out kit, but I’ve not even been able to get to the bios – as soon as the power is on, I’m just getting a string of beeps, which lasts about 20-30 seconds before ceasing. I’ve tried different RAM combos, and even thought it might be the graphics card, but have three to try with, yet no success. Driving me crazy.
I have a brand new Gigabyte
I have a brand new Gigabyte X79 UD5 sitting in the box next to me. In front is an Intel 3930K and to my right are two 16GB quad kits from Corsair-2133 C9 1.5V. And on the box on the table behind me are two Evga 670 FTW’s. I have a new Corsair 1200 W Pro Gold, an Asus Essence, an Areca Raid Card-1882 ix-12 4GB Memory. I have A Direct Connect via an 8088 SAS cable to a CineRaid 4Bay 6GB/sec self powered and cooled with a backplane to take the 8088 cable from the Areca. I have 3 SAS mini 8087 Breakout Sata 3 cable with each supplies four hard drives. I have 4 Seagate highend 300GB 15.7 K Cheetahs ready to be dropped into the CineRaid running 1.2TB in a Raid 0 thought a 6gb/sec raid card with an intel dual core processor and 4 gigs of memory and sitting in a X8 3.0 PCIe slot. The numbers coming out of that box will melt an SSD. I have 4 Vertex 4 128GB ready to be placed into a Raid 0 for the operating system. And to top it off I have 8 WD 1TB Blacks to fill out my Corsair 800D case. I am cooling the processor with a brand new and “rare” Coolitsystems Freezone Elite, and have 5 PWM fans to be integrated into the Bios cooling, with another 6 fans being run off of a Kaze Master Pro A. I am dropping in two Optical Drives- Plextor3d BluRay Burner, Plextor DVD Burner. I will install one USB 3.0 Pro37 U for high speed compact flash reading from a Nikon D800E.
My question is, should I be having second thoughts about the capability of the Gigabyte X79 UD5? I have come to the conclusion that there isn’t an X79 board on the market yet that is a 5 star board hands down. I already know that Intel isn’t showing the board makers their whole hand forcing the X79 folks to get creative with Bios Hacks, and Registry mods to give us 40 lanes. Nothing Native about any of these boards. I don’t need a Rampage three with 30 PCIe X 16 3.0 slots and I run as fast as I can from all of these falsely advertised 16 lane bombs known as Z77’s. The Asus Deluxe for $280 had a whopping 4 PCIE X1 slots- yes I have four sound cards!! and it provide 3 PCIe x16 3.0 slots but they never talked about these board’s mamouth limitations in any of the reviews in that if you put a new 680 in the first slot you have X16, but drop anything into slot 2 and slot one is now back to a X8 which is nothing more than what we already had in the X16 2.0 boards! And if you make the mistake of dropping in anything into slot 3, you just toasted slot 2 and made it a X4 along with slot 3. WOW– what a great motherboard you can have tri sli with a x8/x4/x4 with your new $1500 of 3.0 video cards.
So how long do I wait with all of these great build parts? Gigabyte says they have an amazing X79 refresh, will it be the improvement that is deserving of all these great components? I run from the Z77 as it is an EOL long before it was put on the market. No upgrades coming except a plug called Thunderbolt that has nothing that I own to plug into!
Any suggestions?

I had the same trouble.

I had the same trouble. But I managed to get mine going after having discovered that this board does not like you using XMP at all. Had to turn down to 1333 mhz and have not touched my voltage settings. This is with all 8 channels full. Hope this helps.
