Question GIGABYTE 5700 XT Bios mod fails

[AlleyCat]

Hi,
I am failing to update Gigabyte 5700 XT. The same procedure updates the BIOS on MSI cards with no problem. I follow the instructions on Igors Lab.

The sign of having trouble with the card bios flash shows in GPU-Z. After flash using amdvbflash the values of GPU and memory frequencies is empty. With stock bios there are Mhz frequencies.

Is there any known problems with flashing Gigabyte cards?
Any suggestions on what other forums I may ask for assistance?
Is it possible that the OEM bios is signed, and any modified bios will be rejected?
If the bios is signed, any tools to resign, or would I need to buy a card from a different vendor?

Thanks,

Alley Cat

This is GOLD. Thank you!
I will follow the details and will look for any differences between my settings and your values.
I will report tomorrow.

You are very welcome,

And you may have a good night.

My apologies for the late reply,

We are going to make a mining profile for the both cards, we are going to start with the Gigabyte RX 5700 XT GAMING card first following the below:

0- Download latest MorePowerTool and RedBiosEditor version from this link below:

RED BIOS EDITOR and MorePowerTool for Polaris, Navi and Big Navi | Page 3 | igor´sLAB

New curve options have been added. Of course we would be very happy about a feedback in the forum about the use of this new function! The More PowerTool (MPT) has been also revised once again for the…

www.igorslab.de

1- Turn off completely any overclocking programs like MSI after burner or AMD Wattman after returning to default settings first,

2- Reflash the card with the official bios,

3- Rename the R57XTGAMING-OC-8GD.BIN to R57XTGAMING-OC-8GD.ROM,

4- Run the MorePowerTool program as an Administrative, Click Load and select the R57XTGAMING-OC-8GD.ROM or an amdvbflash backup bios, after that follow as below:
- Under Features tab enable all the overdive features,
- Under Overdrive Limits tab, set:
GFX Maximum Clock 1400 MHz
Memory Maximum Clock 1000 MHz
Under Power and Voltages, set:
Maximum Voltage GFX 850 mv
Maximum Voltage SoC 1200 mv
Minimum Voltage GFX 750 mv
Minimum Voltage SoC 750 mv
Power Limit GPU 150 W
TDC Limit GFX 138 A
TDC Limit SoC 12 A
- Under Frequency tap, set:
GFX Maximum 1400 MHz
Memory DPM 3 - 950 MHz
- Under Fan tab, set:
Fan Acoustic Limit 1950 RPM
Fan Throttling 2400 RPM

After that click Save to get .MPT file,

5- Run the RedBiosEditor program as an Administrative, Click Load and select the R57XTGAMING-OC-8GD.ROM or an amdvbflash backup bios, after that follow as below:
- Under PowerPlay, Load MPT File and select the .MPT that was prepared before,
- Under VRAM Timings, click on the rectangle with (1500 or 1550) MHz and change the tCL to 14 under DRAMTiming1 and tREF to 12000 under DRAMTiming12 for MT61K256M32 Micron and tCL to 14 and tREF to 9000 for K4Z80325BC Samsung and after that copy the (1500 or 1550) strap to the rest of the straps after it,

6- Click on Save to get the .ROM modified bios file,

7- Now Flash the modified bios and restart.

Now you can use HiveOs or MSI Afterburner to tune your card as here it depends on your chip quality and silicon lottery, start with maximum values of 1400 MHz 850 mv core and 950 MHz Memory,

Above is for gigabyte card only,

Please do update me whenever it is possible,

Best Regards.

Good morning.
I am at Step 5 "Under VRAM Timings, click on the rectangle with (1500 or 1550) MHz and change the tCL to 14 under DRAMTiming1 and tREF to 12000 under DRAMTiming12 for MT61K256M32 Micron and tCL to 14 and tREF to 9000 for K4Z80325BC Samsung"

1) The RBE editor will not allow to enter 12,000 to DRAMTiming12 tREF. The edit field can take only 4 digits. What value for tREF should I enter?
2) Changing the tCL to 14 corrupts the rom. At 20 the rom loads correct. With 14 the rom doesn't load. What value for tCL should I use?

Awaiting for confirmation.

Thanks.

Good Morning,
For the tREF of MT61K256M32 Micron memory only enter E02E instead of 810B in the straps of the 1550 MHz directly after that hit the rectangle of the 1550 MHz and change the tCL to 14 and you will see that the tREF value now is 12000.

If your chip cannot handle tCL 14 then increase by 2 to 16 then 18.

I was able to replace the tREF value to 12000. I searched the text string for 810B, and replaced it with E02E.

Windows will not start with tREF value set to 12000 (E02E).
I had to remove the card, remove the AMD drivers, re-flash with a working bios.

What is the next step?

Alright, tREF to 9998 if not then 5998.

The Gigabyte RX 5700 XT are not easy to modify because of their bios, patience is needed to find the best stable vram timings for it.

The problem was with the tCL settings, and not the tREF.
I had to revert to tCL = 20.

I an successful setting the tREF = 12000 (E02E) and the works.

I am getting 60.08 MH / s with the following configuration:
Platform: Windows 10
Miner: Phoenix 5.1c
Power: 129W

I achieved my hash speed target.
I must reduce the power to below 110W.

What are the next steps?

Great results, now try to reduce the core volt of 850 mv by 25 mv and test until you reach a sweet spot of performance to power.

By the way, what about the temperature values.

 

[AlleyCat]

I am starting the optimization on HiveOS.

Memory Temp: 88

The power doesn't go bellow 117W.

What are the next changes?

Now start to reduce the core clock of 1400 MHz by 50 MHz after that decrease the core voltage again.

 

[Mini_Me]

I am starting the optimization on HiveOS.

Memory Temp: 88

What are the next changes?

How about returning the core voltage to 750 mv and decreasing the core clock until you reach 110 W.

Any update to share?

 

[AlleyCat]

How about returning the core voltage to 750 mv and decreasing the core clock until you reach 110 W.

I have achieved 106-108 W at 55.7 without any miner special configurations.

Mem temp: 90c - 92c

I had to test many configurations to achieve power below 110W. I reduced the core v to 715mw. The memory volt is down to 750 (bellow it crashes. )

To increase the hash rate I used the following Phoenix command line:

-coin %COIN%
-fanmin 0 -amd -acm
-mi 1 -mode 1 -clKernel 1 -clNew 1 -clf 0 -lidag 1 -openclLocalWork 64 -openclGlobalMultiplier 4096

With the -openclLocalWork 64 switch I am getting close to 60MH/s, BUT I am getting invalid shares.

1) What parameter I could change to reduce INVALID shares?

 

[AlleyCat]

I backed the memory clock to 860MHz to try reducing the number of invalid shares. Even at memory clock 860, and miner option -openclLocalWork 64 I am getting:

Power: 104W
Hash: 59.9-60.4MH/s.

I will let the system run for a while to test if I reduced the number of invalid shares. I will also monitor on the pool that I am recording ~60MH/s.

Without the miner option -openclLocalWork 64 the hash rate will be around 55MH/s.

I think the bios configuration is now complete. I will start a batch updates to all cards.

You can try first as advised before to keep the voltage of the core at 750 mv and the memory voltage at 1350 mv and reduce the memory by 10 MHz from 950 MHz to 940 MHz and the core by 50 MHz from 1400 MHz to 1350 MHz to reduce the rejected share and keep the power less than 115 W with hash rate around 58.5 MH/s for best performance to power.
The rejected share are inevitable and too much users in the pool will increase that, our goal to get best hash rate with minimum possible power consumption, performance to power, with safe temperature and minimum rejected share.

This result was very good, you need only to decrease the core clock by 50 MHz and memory clock by 10 MHz to reach minimum power consumption while preserving the hash rate.

After you finish the Gigabyte card, how about we start optimizing the Sapphire one.

 

[AlleyCat]

I am going to take a break. I put the Gigabytes in production and I need to reduce the invalid shares errors. I am going to work on testing ways to reduce the errors. I will get to start the mods on the Sapphire tomorrow. I could use information in advance if you happen to have.

My last advice regarding the Gigabyte cards before moving to the Sapphire ones,
In order to easily reduce the invalid/rejected shares, we need to focus on one reason and eliminate the others,
Invalid/Rejected shares caused by either the hardware or the software or both,
Regarding the hardware side, too much undervolting or overclocking or bad optimization will lead to invalid/rejected shares even if we tried our best to optimize the software, the reduction of the invalid/rejected shares will be very small or even it will be the same and not effected by that,
In order to eliminate the culprit from the hardware side, we need to properly optimize it, when it comes to pc components the main element that cause the system temperature and instability rise up is the current (amperes) and not the voltage, according to the equation below:
Power (Watt) = Current (Ampere) x Voltage (Volt) x Power Factor

Because it is a DC system the Power Factor is 1,
From the equation we see that by raising either the current or the voltage or both it will increase the power, more power mean more performance,
In our case, when we increase the clock we increase the required power, to reduce the power while maintaining the stability and safety of the system and achieving the required performance is by fixing the voltage to the minimum stable amount and decreasing the current by decreasing the clock until we reach the desired amount of the power while maintaining the stability and safety of the system,

Therefore, I advise you to fix the voltage of the core at 750 mv and the voltage of the memory at 1350 mv at the memory controler voltage at 750 mv as advised by professionals and decrease the clock for both until you reach the desired power of 110 W or less while maintaining stable performance at lower temperature, by that we achieved our goal while preserving the stability and the safety of the system,
After we eliminate any possible cause of the invalid/rejected share from the hardware side, we tune the software to reduce the invalid/rejected share as much as possible.

I will prepare the profile for the Sapphire cards in advance whenever it is possible,

You may have a good and peaceful day,
Please stay safe and healthy,

Best Regards.
