[rdluffy]

I'm trying to create courage to mod my card, 5700xt gigabyte gaming oc
I heard bad things about bios mod this card, that is somehow blocked.
Anyone tried this with this exact model?
Doing 54.7 mhs here without bios mod

The problem is with rev 2.0, but you can put bios rev 1.0 in 2.0 and all working...

I'm in BIOS Mod too and I get this values with 110W on the wall.. it ca arrives to 57-59Mhs depending Memory luck

6 pcs GPU and all system eat 943W at my last bios and settings. Stable.

Yahh you have to look for older BIOS as the bios editor for latest BIOS doesnt work properly as the bios is locked.

Would you like to share your bios file in here? I'm not confident if i, doing bios manual moding alone, at least you tried it and it was stable. Hope someone here share his rx5700 file here. Thanks

Yo should analizar your rig... it is 200W higher in wall that it  should be for most profitable mining

What i have noticed, Samsung memory GPUs are great for power consumption.
This 8GPU rig does 450mh/s at 1080w from the wall. It is in closed case , because of the high efficiency fans case itself consumes 130w.
So total for 8xgpu is 450mh/s @950w, which i think is great.
These cards are MSI mech RX 5700XT , i know many people complaining about mem temps on these - but look what temps. i have.
Same rig with same cards with Micron memory uses 300w more.

got a few power color rx 5700XT with samsung memory... and can't mod them ... i can but 2 cards already died......
cant push too much from them ....Powercolor RX 5700 XT 8GB 113-D19901-XT

what do you mean "died"? You have to RMA it?

[joaogti36]

yes.. i've sent them to rma.....
after a few minutes of mining cards died (disapeard from system)
no computer can find them in any slot....

No, I only update the bios from Gigabyte official website

As I said above, I only did the reccomended bios update of Gigabyte website, easy, but I didn't modify or unlock my bios after that 

Yahh you have to look for older BIOS as the bios editor for latest BIOS doesnt work properly as the bios is locked.

Do I have to put the old bios of my card, to unlock? I'm little confused here, sorry

Yeah the latest BIOS are locked and cannot mod the timings. Igors lab bios editor doesnt work properly on latest bios

Didn't have any difference over 6000

These are my first 5700's:


and with 1380 clock:


The power consumption for Samsung memory is amazing. They take 4-5W more than my 580's and give 1.75x more hash. For 3 cards the total power with the MB pack from the wall is 395W. If only I could find 40 more cards with Samsung memory...   I will replace all my old cards. For now they are better even compared to nvidia 3800. Which 5700's models are known to be with only Samsung memory?

P.S. With these settings I get <1% stale shares from the pool and  ~440/1 accepted/invalid shares on one of the gpu's in the miner. On the other 2 gpu's it is ~1000/1. I guess it is good enough and not worth lowering further the mem clock. I use the standard 1550 mem straps+5990 ttref.

Yes Samsung memory are amazing performance also on RX5600XT.
From experience any GPU could be with samsung either micron , even same box from factory have got half samsung half micron. Its lottery

With TRM I even got better hash per watt. I lose 1MH but the power is lowered by 5W per card (tested both on hiveos and on my wattmeter). It seems that the new TRM kernels are better optimised for 5700's, since I got less invalid shares.

I know that most of the cards from Sapphire are with Samsung memory, while for the other brands it is the reverse - more are with Micron. Micron needs 30W more per card and gives 3Mh more, which is quite a bad ratio. Unfortunately, around here Sapphires prices are 33%+ higer than the others.

Hi, do you have to change the DramTiming12 on both of the memory types in RBE?
