GIGABYTE Z690 Tachyon

For everyone who gets a Gigabyte Z690 Tachyon, here is some information including bios.

 

As applies everywhere else in the OC area, the settings shown here are NOT suitable for 24/7 Systems! Therefore, please do this at your own risk.

 

The settings vary depending on the CPU and memory; here, as is so often the case, you have to find the right settings for yourself.

 

With the X2d Bios it is possible to read out "Biscuits" or as it is called by Asus “SP”, ATTENTION, these do not match the values from Asus, as the readout method is different. Thus, an SP90 at Asus can be Biscuits 93 at Gigabyte. In the "1 Core Voltage Prediction" area you can read out the default Vcore for individual cores. The lower this is, the better this core is suitable for single-core benchmarks;).

CPUs with Biscuit from 93 are suitable for Extreme-OC. However, it is also possible that these CPUs (12900k) only achieve 6.6 GHz in Cinebench R20.

 

For OC not many settings are necessary with the Z690 Tachyon;).

 

First the most important, CPU menu.

Here it is very important to select "Nomial" in Full OC Mode. This prevents false results and helps with Extreme OC to prevent CB.

The E-Cores of the new CPUs can be deactivated in the "CPU Cores Enabling Mode". For this it is necessary to select "Selectable Mode" and deactivate the unnecessary E-Cores.

Of course, C-States and CPU EIST should be deactivated for OC.

 

As usual, you can select the X.M.P profile for the memory or work with the XMP Booster. I like to work with fixed values, so switch off everything that is not necessary and set it by hand.

 

In the picture below my "default" settings for 6600 are attached.

Important values are DRAM VDD / VDDQ and VDD2 CPU.

DRAM VDD / VDDQ are sufficient at 1.45V for both Air and Extreme-OC.

VDD2 CPU is dependent on the mem clock. Guide value here at 6600-6800 Mhz (Hynix) 1.45V - 1.50V.

The individual voltages for Mem-VDD and Mem-VDDQ are to be set in the DDR5 Voltage Control area. Here as a guide value 1.50V for 6600. Here, too, it is my memory, I know what it needs, you have to find out for yours :)

If your voltage or timing settings do not match, the board will restart several times. To get into the BIOS faster without losing the settings, you can use the LIMP-Mod button.

 

The timings I have set can be used on air with 6666 Mhz without any problems. With a cold CPU, up to 6900+ are possible. As soon as the CPU and memory are cold, over 7000 are no problem either.

Only 5 voltages are important for Extreme OC:

Vcore: 1.60V - 1.65V

DRAM Vdd / VddQ: 1.55V

VDD2 CPU: 1.60V

DDR5 voltage control

VDD A0 Voltage: 1.60V

VDDQ A0 Voltage: 1.60V

With Extreme-OC it is important:

Only set the voltages at around -120 and only then boot into the OS. In the OS, the temperature can be lowered to full pot.

Should you get a blue screen, please press the "Reset" button.

After a restart, full pot is possible without any problems. In this case it is not necessary to lower the temperature and a restart with full pot is possible.

If you don't do that, the board may start without a postcode, then you have to heat up to about -145 °, depending on the CPU, before the board starts normally.

After such a start, your settings can be lost, so a look in the BIOS after a restart is not wrong.

 

 

One more thing about the GTL tool, this tool currently only works under Windows 10! If this does not show anything when you start it for the first time, create a shortcut on the desktop and start GTL in admin mode.

What the different about 'DRAM Vdd / VddQ' in the 1st front page & VDD / VDDQ on the DDR5 Voltage control page?

Can it be set in sync? Say 1.55v for the all 3 variable values?!

Or 'DRAM Vdd / VddQ' must be slightly lower?

If you mean VDD2 and VDD+VDDQ yes, but it`s not really necessary.

Only for LN2 I used all these 3 settings with 1.60v

Taken a cropped shot part from 1st post:

That one, I mean. On the pict above also you set the DRAM Vdd / Vddq: 1.45v
And VDD A0 & VDDQ A0: 1.5v
Why always have a 0.05v gap? A necessities?

  • 2 weeks later...

did some benching last night as well on x2i, it once trained 6800 with tight rtl's and was gb3 stable, then never trained 6800 again. also had to do a few power offs and clear cmos to recover from 28 - 54 loops... is sa locked on non-k chips btw?

on the filp side, once it had trained at reasonable speed and timings, doing the bclk oc was really easy and straight-forward. also gtl for cache and p core multi worked great!
