Question XFX 5700 XT Cards

[Anthony]

Preface: @Mini_Me has demonstrated profound knowledge when modding the 5700 XT series of graphics cards, and for those looking for an awesome tutorial, please reference https://www.igorslab.de/community/threads/gigabyte-5700-xt-bios-mod-fails.3304/.

Story: At the present time, I own 40 XFX 5700 XT video cards; I have 40 more on order to make a total quantity of 80 cards. With this many cards, squeezing out an additional 1 MegaHash (MH) from each card would translate into +80MH. Out of the box, the stock bios on these XFX 5700 XT cards reflects about 51MH per card. With bios modifications and tweaks, it is possible for me to obtain between 54MH-56MH per card.

Configuration: I have 5 rigs in operation and soon I will have 5 more in operation. Each rig uses 8 cards. I am using HiveOS to manage my rigs.

The importance of bios modifications: Basically, using bios modifications allows each card to provide a better hashrate -- and as hashrate increases, potential ETH mined increases. (More Hash == More $$). Bios modifications also change how each card consumes electricity -- and aside from the initial cost of computer components, electricity is the second greatest cost when it comes to mining.

• Stock Bios: 80 Cards x 51MH from each card = 4.080GH
• Modified Bios: 80 Cards x (54MH || 56MH) = (4.320GH || 4.480GH).

The delicate balance in bios modification reflects a specific relationship between: 1.) Power Consumption, 2.) Temperature, 3.) Hashrate, and 4.) Stability vs. Instability. In my opinion, the goal of proper bios modification means that: (a.) each card consumes as little power as necessary, (b.) each card remains within "safe" temperatures to prevent card damage, (c.) each card produces the maximum hashrate, (d.) each card remains stable, which is to say that the card does not produce "invalid" shares or other errors that get in the way of making money.

The above mentioned thread link reflects a dialogue between two members, @Mini_Me and @AlleyCat. The thread is several pages long because it reflects a series of tests (trials, errors, and new trials with new errors, etc.) with different bios values and with different values in HiveOS. There are multiple variables in play (both on the bios tweaking side with MPT and RBE and on the software tweaking side in HiveOS), and changing one variable influences other variables. The thread is so long because many different settings were tried out in order to achieve the best possible result for specific card manufacturers, in this case manufacturer Sapphire and manufacturer Gigabyte.

This post in particular captured my attention: https://www.igorslab.de/community/threads/gigabyte-5700-xt-bios-mod-fails.3304/post-79315.

RBE modified values in use:

Option 1 (Preferable and Recommended), applying Apple Inc. vram timings straps linked below, once for MT61K256M32 Micron, and Save the vbios after that load the saved vbios and once again apply the straps for K4Z80325BC Samsung if it is existed and save the vbios again,

As you can see, in order to achieve stability (prevent invalid shares, rejected shares, and phoenixminer reboots), I have to run most cards at 1375 core. Other cards I had to reduce to 1325 core. Some cards run at memory 930, some at 905, some at 900, and some at 890.

I know my cards can give better performance. Even though I have reduced power values to reduce # of invalid-rejected shares, phoenixminer still reboots from time to time, and sometimes, I will have a card that will "stop" and disappear ... which causes the phoenixminer rebooter. For these cards, I reduce values.

Any advice from master @Mini_Me would be appreciated.

Please use one of the setting below to decrease the memory temperature,

Core clock, VDD : Memory clock, VDDCI, MVDD, Hashrate in TeamRedMiner,

- 1330 MHz, 750 mV : 850 (1700/2) MHz, 800 mV, 1350 mV, ~52.10 MH/s,
- 1345 MHz, 750 or 760 mV : 865 (1730/2) MHz, 810 mV, 1350 mV, ~53.10 MH/s,
- 1360 MHz, 760 or 770 mV : 880 (1760/2) MHz, 820 mV, 1350 mV, ~54.10 MH/s.

Thank you very much @Mini_Me!! I'm going to try these values and I will keep you informed of the results obtained.

Has anyone tested the "b-mode" configuration by reducing the core?

 

[dreptroman]

Hey Guys. Please try the B-mod of TRM.

Can Mini_me help us with some C clock settings that should work?

It is supposed to shave 9W for each card!

Navi 5700XT/5700 Transition
	===========================
	If a driver that supports large allocations is installed, the miner will default
	5700XT/5700s to the new B-mode, using as much vram as possible on the gpu. The
	main benefit from using this mode is support for high hashrates at significantly
	lower core clk+voltage settings compare to A-mode and previous TRM versions.
	For a 5700XT/5700 tuned to previous TRM versions, our tests indicate that you
	can drop core clk ~100 MHz and voltage -50mV in B-mode while still preserving
	hashrate (although often with a tiny loss). The efficiency increase is an
	obvious trade-off win even with a small hashrate decrease. If you're on a well
	defined voltage curve, you shouldn't have to touch your voltage settings,
	lowering the core clk is enough, otherwise you should lower voltage manually as
	well. You might need to retune if gpus crash at the lower settings, slightly
	raising voltage until stable again.
	If you for some reason can't run in the new B-mode, you can switch to the A-mode
	manually with --eth_config=Axxx (if you're not familiar with this argument, see
	USAGE.txt for more info).

Hi Guys!! Sorry for the late update to this thread... busy days at job.
I have tested the 3 options of values that kindly give me @Mini_Me... but with not luck regarding mem temps and a little reduce of power consumption in the last sets of values.

First I show you how was the values before testing (with the numbers of page 32 of @Mini_Me guide)



Then... with the first set of values and after 2 hours of mining (this values give me a copule of reboots with GPU dead errors):





Second set of values - 2 hours mining:


Third set of values - 2 hours mining:



Have to say that as I said in my first post the reboots with GPU Dead errors appears from time to time since before the tests and they are always GPU1... I have tried switching Cards and Risers but the errors still GPU1; now I'm testing without using that particular pci-e slot on motherboard.
For now I will follow the advice of @Mini_Me and turn off the rig for an hour every 2 days. I have not test yet the vbios from @Anthony on my cards... I think thats the next step.
Thanks guys for your valuable help.

I had a similar issue with RX 5700 (non XT), and I solved the issue by setting the following minder option:
--eth_config=B,B,B,B,A
This settings set the GPU4 to mode A, and GPU' 0-3 to B.

This is a workaround. I would try to modify the maximum TDC Limit GFX +4A

Hi @AlleyCat !! Thanks for your answer... One newbie question: I have to set to mode A the Card that has GPU Dead errors and the others to mode B?
Thanks in advance

Hi and welcome,

Please could you inform what is your power supply PSU model and rate?

 

[pattone]

Hi and welcome,

Please could you inform what is your power supply PSU model and rate?

I have 2 CoolerMaster PSUs 650w Plus Gold each

 

[Mini_Me]

I have 2 CoolerMaster PSUs 650w Plus Gold each

And your motherboard model?

 

[Mini_Me]

I have 2 CoolerMaster PSUs 650w Plus Gold each

And are you using 1x8pin to 2x8pin power splitter to connect the cards to the power supply?

 

[pattone]

And are you using 1x8pin to 2x8pin power splitter to connect the cards to the power supply?

I'm not using splitters... Motherboard ASUS ROG STRIX B450-F GAMING, CPU AMD Ryzen 5 2600, RAM 8GB DDR4 3200mhz

 

[AlleyCat]

Hi @AlleyCat !! Thanks for your answer... One newbie question: I have to set to mode A the Card that has GPU Dead errors and the others to mode B?
Thanks in advance

Correct. The TRM rev. 8.0.0 defaults RX 5700 GPU's to mode B. By forcing the GPU that fails to use Mode A you will be running like the previous kernel.

Please note that this is just a workaround.

Please do check the cables connection of the cards to the power supply.

Hi!

With this settings. What SOC frequency can we use on HIVEOS OC? Its possible to down some consume and heat or with Micron memory is recomended stay default like you said in guide @Mini_Me.


This is the RIG and i woud like down the heat.

Hi!

Hi and welcome,

For stability on the long run, the default SoC Maximum clock is recommended,

You can still set the SoC maximum clock at 957 MHz for memory clock 910 and below or at 1093 MHz for memory clock 915 MHz to 950 or 960 MHz.

By the way, if the SoC maximum clock is set at default then the DPM scaling will automatically set the values based on the memory clock.

Please could you inform how the gpu are connected to the power supply?

Hi @Mini_Me!! sorry for the late update... Last night when we talked it was late night here and I go to work early. The GPUs are connected to the PSU with one 1x8pin and 1x6pin connectors and the risers with molex; I know that for risers 1x6 connectors are better but I don't have enough of them in my PSUs and I believe that adapters arent good too. The GPUs are MSI rx5700 MECH OC (non XT). I have read that a lot of people has high mem temps with these model in particular; I'm thinking in try the thermal pads solution too. Thank you for your constant support.

Hi and welcome,

No worries, I believe that 2 gpu are connected to 1 psu, correct.

Please do remember that your 650 watt gold output is approximately 520 watt and the quality of the cables and risers should be good to minimize the risks and the cause of problems,

Regarding the memory temperature, you can decrease the memory clock until the desired temperature reached.

Hi @Mini_Me!!! Thanks a lot for your constant help and sorry to bother you again. I ask you a beginner question... Where do I set the Core State to 1 and Mem State to1 for the rx5700s?? Are these values set in the page 32 guide? Because for what I have read these values in the HiveOs OC profiles aren't for rx5700 cards.
Thanks in advance

Hi and welcome,

There is no need for these options anymore that is why I removed it from the guide.
