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

It looks like Apple's straps work optimal on my Micron cards.
I think these are stunning numbers.
Total rig with 6 cards 296MH/s, power at 580W (reported by HiveOS) at a ratio of 0.51 MH/s/W
All the cards took the Apple Inc strips, and all are Micron memory.
I may modify the power consumption bellow 580 as long as I don't lose too much hash or the ratio below 0.5.

Please note that the rig is "fresh" and will need to "cook" for a day to establish that it is stable.

The remaining issue is what best configuration we could find for cards with Samsung memory. I will run the tests above with the Apple Inc straps.

I accept the request, and I will do Test 1 with Apple's straps. I will do the test on the card with the Samsung memory.

I confirm that TEST 1 swaps of straps, provided by Apple Inc., the card is working.
HOWEVER, at 900MHz, I am getting Invalid shares.

My sincere gratitude for your time and effort,

I updated the performance power table for higher stability with almost the same performance in case if you one day need it,

You may have a good sleep,

Good Night.

It is a pleasure. I am glad I could get help from you and the community, and also to give help. I hope the efforts will benefit may others.

Have a good night. I will test the power settings tomorrow.

Good morning,
I hope uou have a good rest yesterday,

My apologies for not mentioning this before that it is important when applying test 1 settings to Apple straps to preserve the tREF value for each clock as below:

Memory Clock - tREF
1000 MHz - 3900 (Samsung & Micron)
1250 MHz - 4875 (Samsung & Micron)
1550 MHz - 6045 (Samsung & Micron)
1750 MHz - 6825 (Micron only)
1800 MHz - 7020 (Samsung & Micron)
1875 MHz - 7315 (Micron only)
2000 MHz - 7800 (Samsung & Micron)
2250 MHz - 8775 (Samsung only)

After that we test starting at memory clock of 900 MHz.

Regarding finding the best setting for Samsung memory to achieve stable memory clock higher than 900 MHz or faster with tighter timings,

First we are going to copy the strap of the 1250 MHz of Apple to the rest while preserving the Apple tREF values above and test with core clock at 900 MHz,

Second, we are going to go the opposite way by copying the strap of 2250 MHz of the standard one first to the (1800 & 2000) MHz straps with applying the Apple tREF values above and test with stock voltages and increasing the voltages if needed, we will start with memory clock of 910 MHz and increase it by 10 MHz to 990 MHz and see which value we will get stable result with no invalid/rejected share.

Good morning.
I confirm the following configurations:
1) Card: Sapphire 5700XT Pulse, memory by Samsung

2) Power Table been updated with the following values:
- Under Features tab enable all the overdive features,

GFX Maximum Clock 2200 MHz

- Under Fan tab, set:

3) Memory straps provided by Apple Inc with the following values:
1000 MHz - 3900 (Samsung & Micron)
1250 MHz - 4875 (Samsung & Micron)
1550 MHz - 6045 (Samsung & Micron)
1750 MHz - 6825 (Micron only)

1875 MHz - 7315 (Micron only)
2000 MHz - 7800 (Samsung & Micron)
2250 MHz - 8775 (Samsung only)

4) HiveOS OC settings, NOT optimized:
Core: 1420
VDD: 800
VDDCI: 800
MVDD: 1350
MEM clock: 905

I think we found the memory speed limitation of the Samsung memory. There is benefit for running the Samsung memory card, which is lower power. The ration of MH/s per W is 0.54, which is greater ration than 0.50 I achieved with the Micron memory, running at 58.9MHs/117W.

Next steps would be to optimize for low power on all cards using the new Power Table.

The performance power table is only for testing the Sapphire card with the Samsung memory to find the best result after that we will optimize it for the best performance to power (sweet spot).

OK. Got it. I thought is would be the final Power Table. Now I understand that it is temporary, and for the purpose of testing the cards.

Initial Report:
The memory straps 1250 with Apple tREF crashes the card, and the card is not functional. I am working to revert the bios to stock.

Great, now it is confirmed after your help and analysis the both memory chips that the Micron memory die revision is better than the Samsung as the 1250 MHz strap timing of Samsung is the same timing of Micron 1550 MHz strap, and the 1550 MHz strap timing of Samsung is the same timing of the Micron 1800 MHz strap that is why copying the strap of 1550 MHz to the rest in Samsung yielded to a small improvement compared to the Micron one.

My apologies for the misunderstanding, it is my fault not to clarify and explain properly.

Here are the results:
Memory speed 960 was the only memory speed that did not crash.

Wonderful,
By the way, the 2250 MHz strap used here is from the vbios of the Sapphire card with Apple tREF or it is the 2250 MHz strap of Apple?
And let us test with memory clock at 915 MHz and to increase by 10 MHz until we reach memory clock at 995 MHz.

From Apple Strap
Note: for test stability I increased the VDDCI to 900 and MVDD to 1390.

Please find the report for frequencies 915 to 995.
It looks like the stable frequency above 900 is 955. I tested again the 960 and I think it is on the borderline.

Note: for test stability I increased the VDDCI to 900 and MVDD to 1390.

After we test with memory clock at 915 MHz and to increase by 10 MHz until we reach memory clock at 995 MHz, we will start tightening the timing for the stable ones and after that we optimize the power.

 

[AlleyCat]

The Samsung memory card started crashing at 955. I though to let you know.
I think because I reduced the VDDCI and MVDD.

Once I put back VDDCI to 900 and MVDD to 1390 the card started working OK at 755MHz.

Alright, until now what stable memory clocks we reached from (910 to 990) MHz and from (915 to 995) MHz with 900 mv VDDCI and 1390 mv MVDD?

955 at VDDCI to 900 and MVDD to 1390

955 at VDDCI to 900 and MVDD to 1390

The 960 MHz, is it still stable?
