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.

Here's 136W and 120A - still not reaching the target clock speed of 1390, I went back to the first post by OP and realized that in his MPT, he had 140W and 140A originally. Do you remember if he was able to use 126 and 120A for the same hashrates? Seems I may have to go up to 140W. Again, thanks for your feedback and time. I greatly appreciate it.

I might sorted out the problem, please in more power tool do the below,

- Under Feature Control, set:
ACDC: Check (Enable)

I've gone back to the 126W and 120A and enabled ACDC:

Still not able to get to that core:

Edit: Flashed it on the second gpu

GPU0 has 125W 125A with ACDC and GPU1 is 136W 120A ACDC.
125W isn't enough to keep the core as shown in the miner

GPU1 was flashed with 130W and 114A, below you can see gpu1 couldn't reach 1380 on 130W.

Here are my results:

136w isn't able to push 1440. My overclock settings are below:

I will let this run over night. I have flashed 150W/132A to all 3 cards. GPU2 still seems to have a bit of trouble holding 1440, it's currently at 1430. Please see below. Are the memory temps safe for 24/7 ? Thank for all of your support.

Edit: I will try with GFXOFF and DPM_GFX_PACE tomorrow.

The memory temperature are very good and it is possible to decrease the core clock to 1430 at 800 mV and Memory clock at 950 MHz, 890 mV, 1365 mV and it should produce 58.10 MH/s with TeamRedMiner,

I look forward to your update,

You may have a good day.

I decreased the clock on all cards to 1430 and 950 as of now since I did get a few restarts overnight. I reflashed with GFXOFF. DPM_GFX_PACE is actually enabled by default. Here is what my Feature Control looks like :

Core clocks are being reached on call cards. Should probably be more stable. I will monitor for a day and report back tonight.

I am going to send you another version of original vbios as I suspect something is not right with this current vbios.
