Gigabyte X470 AORUS GAMING 7 WIFI overclocking & discussion thread
Known non power delivery ICs:
* ICS 9FGL1214AKLF (clock generator)
* ITE IT8686E for SuperIO + ITE IT8792E (near PCIE slot)
* Realtek ALC1220-VB + ESS Sabre DAC
* Richtek RT8288A for USB 3.0 DAC UP 2
* Intel 1211-AT Gigabit LAN
* Asmedia ASM1143 USB 3.1 controller
* ITE IT8295FN (RGB controller)
* Four ASMedia ASM1480 PCI-e switches (on my board it is NXP L040838)
Dual BIOs with replaceable BIOS chip explanation
It is advisable to use Single BIOS mode such that the second chip is untouched. Flash only via USB in the BIOS itself via Q-Flash. Don't flash in Windows or other OS.
Try to load Optimized Defaults so that all settings are stock before flashing the BIOS.
When you have a corrupt main BIOS you can then flash over the main BIOS by switching the BIOS to the 2nd BIOS.
1. Set board to single BIOS mode if not already.
2. Boot off the backup BIOS
3. Once in the BIOS flip the switch to the BIOS you want to flash,
4. Use Q-Flash to flash the BIOS. After reboot it may power cycle up to 5 times for memory training reasons.
Known quirks, not necessarily board specific
* The AMD CBS menu for XFR2 and Precision Boost Overdrive in Gigabyte BIOs is under "Peripherals"
--- PPT : Package Power Tracking (power limit) , default is ~ 140W
--- EDC : Electrical Design Current , "Indicates the maximum current the voltage rail can demand for a short, thermally insignificant time"
--- TDC : Thermal Design Current
* HPET enable / disable is under "Power"
* Voltage is around 1.45V-1.5V if on auto (in software) for Ryzen 2 due to AMD's 2 core boosting , multimeter readings typically below 1.45V
* Recommended SOC Voltage for Ryzen 2nd gen is 1.05 - 1.1V , may escalate to 1.2 or more if using XMP profile
* Gear Down Mode should be disabled if you intend to use odd timings such as CL15 15-15-15-35.
* AC 9260 Wifi might not work on older Linux kernels before 4.14 or on particular Linux systems (http://forum.gigabyte.us/thread/4007...r-aorus-gaming)
----> From my testing it works fine with Ryzen 7 with SMT turned off and also with downcore control set to SIX (3+3), so this issue might be due to more than 16 logical cores. (see https://bugzilla.kernel.org/show_bug.cgi?id=199551)
Quick OC tips
* Use Classic mode of BIOS for all advanced settings
* Use manual 4 main memory timings to start with , typically 1.35V DIMM (memory) voltage is required for XMP along with 1.05 to 1.1V SOC voltage
* Manually set ProcODT to 60ohms for most memory kits
* DRAM Termination typical is half of DRAM Voltage
* Check memory ICs for your kit using Thaiphoon Burner or the list at https://www.overclock.net/forum/1805...on-thread.html
* Check memory timings in Windows with the Stilt's Ryzen Timing checker: https://www.techpowerup.com/download...iming-checker/
* "Normal" in Gigabyte BIOS is "offset" for other vendors
* V_Droop is minimal on High LLC (about -0.02V under stress load) , Turbo is more or less what you set (less than 0.02V deviation in total to what is set in BIOS), and Extreme has no V_Droop may have an overshoot
* BCLK overclocking can be used up to around 103 - 104MHz , to avoid touching the multiplier and yet still maintain maximum clocks under light load
* Use Clear CMOS to clear all settings
* Use advanced fan curves in Smart Fan 5 to set your fans , calibrate for more accurate fan curves
* Stress test thoroughly before proceeding with your overclock for daily use, programs such as Prime95 or y-cruncher help you identify weaknesses in cooling
1. Do I need both the 8 pin and 4 pin CPU power connectors? No unless you plan on using it subzero or pushing ridiculous voltage and power.
2. What's a safe voltage? Generally it is recommended to be below 1.425V (non-stress), Gigabyte recommends a more conservative < 1.35V all core
3. Can I use a 1st gen Ryzen on it? Yes.
4. Do I need Appcenter for SIV? Yes. It's a prerequisite (required for installation).
5. Where do I turn off RGB? In the BIOS you can turn off RGB Fusion under Peripherals.
6. Where can I turn on virtualization / can only use one core in my VMs ? It's labeled SVM Mode under Advanced Frequency Settings ---> Advanced Core Settings
7. IOMMU setting is under "Peripherals" (see also this post for IOMMU groupings per F2 BIOS)
8. Typical overclock on ambient (air / water) for Ryzen 2nd gen is ~ 4.2-4.3GHz < 1.45V
Please be aware the pre-installed backplate may interfere in computer cases with integrated standoffs. It protrudes roughly the same height as a 6-32 motherboard standoff.

* This is Rev 0 because as Gigabyte's X470 boards do not have the PPT/EDC/TDC setting (as their X370 boards do) the only setting really is the scalar.

I have the predecessor, the Aorus X370 K7. Apart from the problems with Creative soundcards it performs solid. I would assume, that the problems with soundblaster cards are solved with this board.
1.425 volts top are not a safe voltage.
My apologies (to myself mostly) for even bothering to post in an AlphaC thread, but do be warned that above 1.4 you're really asking for degrading. That's your highest ceiling.
1.425V is the max voltage per Stilt's interrogation of the Ryzen 7 2700x , I didn't pull it out of thin air:
1.425V is the recommended max voltage from Robert Hallock at AMD for Ryzen 1 too:
As far as manual overclocks:
If you run really high LLC (i.e. instead of medium or "HIGH" you run Turbo or Extreme) then obviously you need to account for that. If you are running full on AVX then you need to account for that. There's an inherent 0.02V V_Droop present with LLC set to HIGH. If you are on air then obviously you need to account for temperature also rather than just power and voltage, which means ~1.35V / ~170W is likely better. PB2 only kicks in below ~60°C to maximize reliability of the silicon.
You're fixating on voltage but if you pay attention to AMD's PB2 and XFR2 , the CPU will drop to 4.1GHz / ~1.2 to 1.3V only when AVX is being used to maintain the same power usage (power is not just based on voltage , gaming or idle at 1.4V is not the same as flogging the floating point units at 1.4V). If you turn on PBO the CPU will maintain around 4.175 - 4.225GHz.
There's three main variables used for the PB2 algorithm: current (EDC/TDC), power (PPT), and temperature.
When it comes to this Ryzen stuff, AlphaC is one bad ass dude. I wouldn’t question anything he says!
Hello fellow Gigabyte owners
I bought this motherbord on Friday, along with a 2700x
the 2700x OC'd like a charm to 4.1 at air - 1.3v
I did not tried to further tweak the voltage, it's on the test bench with stock cooling now
when the times comes i wil install this inside my rig and my custom loop
still trying to be stable with my samsung B-Die , dual rank kit F4-3200C14D-32GTZ
setting the XMP and Dram voltage to 1.35/1.37V results in a boot loop
I am now searching the forums for settings.
unfortunately, most of people here are using Asus CH6 motherboard
some voltage settings seems to have another name in Gigabyte's BIOS
Asus : VDDSOC
Gigabyte = VCORE SOC ?
Asus = DRAM Boot Voltage
Gigabyte = ?
Don't use XMP on Gigabyte boards, it's problematic. You likely want to turn off Fast Boot, set the 4 main timings + 1.35-1.4V memory voltage + 1.05V-1.1V SOC voltage. Try ProcODT 60 ohms too. Then let it perform memory training.
I am running bios F4E and the only issue I have come across is the bios one day failed to post no matter what I tried.
I ended up booting from the back up F2 and reflashed the primary with F4e again and all is well.
I'm surprised the ram I am using actually works correctly with XMP, its a 32gb set from evga ddr4 3200 C16.
This kit has not worked correctly in the past on my CHVI only would work at 2666.
Bought this one as well. Dont like Asus or MSI and Asrock seems to delay delivering.
A key thing to note which I put in the first post is sometimes on Gigabyte AM4 boards it will go insane and flash the Backup BIOS with the main BIOs. To avoid that from happening you should set the Dual BIOS mode to single BIOS.
Doing so ensures that they are essentially physically isolated.
The other major quirk (not an issue just why?) is Gigabyte put AMD CBS options inside the Peripherals tab. They likely need a new UI designer.
By the way if you purchased the board from Newegg or Amazon you can register to get a free mechanical K83 keyboard (ends May 31).
Link is here: http://event.gigabyte.us/review/
If you don't want to use the keyboard I think you can give it away or sell it on Ebay.
