AMD FirePro W7100 8GB. .... Hidden GEM 42MH

[themisters]

@stryfe024 after a few tweaks with editing the bios, my card is getting the highest hashrate (22ish +/- 2) at 800 on the core.

It is running super hot, but is stable, I’m going to apply new thermal paste to see if that helps too.

I’ll see if I can tweak a little more, but the overclocking settings don’t seem to do anything with the w7100, except change the DPM, which obviously you need to do in the bios editor to find your cards most efficient setting for mining.

Here is my current bios tweaks, running DPM 4 stable:

Using: TongaBiosReader/TongaBiosReader_v1511181344.exe at master · Hedzin/TongaBiosReader · GitHub
to tweak the bios.

im a tad afraid of the tonga just yet. Thanks though! I derped out. The hot card was one i was using the Bios from Mike on. I applied to both and theyre both beasting out…on the backend anyway. When I applied the factory BIOS to both they chill out. The BIOS is the one posted by Mistokes18 on Feb 25th on this thread. Im a total noob to github.

So Im one day away from getting my 1st payout from 2miners from this thing! yeeet! haah Is this a normal mining graph or are these w7100s hodling and skeeting since they have the mem bandwidth logjam as Farkeytron mentioned? No invalid shares at least.I get 2miners uses shares as an avg hash rate. Should I expect a better payout or a more steady poolside hashrate from like ethermine? Im going to try the latter now that my hashrate is up a bit and I cant get the w7100s to handle KAPOW for Raven. Think HiveOS pool will give me the full 146.2 mhs it says Im mining at if i eat their fee? This is literally my 1st foray into GPU mining since I gave up my CPU mining of Doge in 2014. uggh. Happy Birthday. lol

What editor is this? I have Tonga Bios Reader 2.0.5888.24717. This is way better. Please share! Thankl you!

[El_Minero]

I just got my hands on a W9100. Can the OC settings be input in the HiveOS OC entry box rather than flashing a customized bios or is the customized bios required? Can you share your settings?

[farkeytron]

I believe the W9100 is locked. You can certainly try using HiveOS to change the clocks.

If it fails to work, you’ll need to use a BIOS mod

[El_Minero]

Thank you. Can you share the clocks you are using?

[blackmermaid18]

hi what do you use to flash?
i’ve treid ATIflash 293 and amdvnflash 3.15 and getting " error reading from rom" when i try to program.

[blackmermaid18]

how did you flash?

[llywelyn]

amdvbflash should work just fine, I believe it has to be 3.04+ to work correctly.

[blackmermaid18]

i was able to successfully flash bios, but W7100 no longer reconige

do i need to uninstall AMD pro software and re install?

[llywelyn]

run amdvbflash -i and see if the program is recognizing any gpu connected.

[blackmermaid18]

looks all normal but something is wrong.
i think my GPU is semi bricked

hmm, is it throwing any error when you mine with it or use it? I’d try reinstalling the drivers because the bios test passed so it shouldn’t be bricked, If that doesn’t work try re-flashing the bios using atiflash 3.04+ I know that that version has some features that work better with flashing vs other version’s. make sure its the “+” version and not the regular 3.04. I’m not sure if 3.15 has the same features as 3.04+ so that could be the issue.

[farkeytron]

Windows will screw up with modded BIOSes with AMD cards.

Try HiveOS on a USB stick on your PC and see if it works.

The alternative is to use a Windows driver patcher to bypass the driver check in Windows.

[blackmermaid18]

i brought back from the dead!
i kept getting failed with flashing from back up (made from GPU-Z), but no luck.
i grabbed another w7100 and backup bios with “amdvbflash” and flash with that bios worked!
looks like Bios part number is different with Modded version.
my cards are Legacy BIOS Part Number 113-C7670400-103
and modded bios is Legacy BIOS Part Number 113-C7670400-102
not sure this has to do with modded bios flash failure.

[blackmermaid18]

maybe this is the answer on my case.
Since i do not have wireless adapter with ethernet ext, I was using wifi USB with windows.
maybe i should try using HiveOS to flash my card.

thanks! ill comback in few days after i get my different wifi adapter

[blackmermaid18]

I know setup HiveOS on my cheap rig.
installed PCI x1 splitter 4 connected risers. (still missing 6pin splitters, so only runing 3 right now)

Question!
im noob with mining & flashing bios.
Im trying to undervolt my cards (which they are all bios 103 , which cause issue when i flash with mistokes18’s bios.?) I try to read his rom with Tonga Bios Reader, but highlighted section shows 0 value.

this is my factory bios reads

can someone upload bios read screenshot for me?

thanks,

Update 2:
eventhough each card was showing 42MH but actual hash was around 12~17MH each. was barely getting 40~50MH with 3 W7100s.
when i try to mine with teamredminer, i see 9MH, 15MH, 15MH on each cards.with mem clock 1250HZ.

I give a shot to mod bios based on Mistokes18’s bios. and successfuly modded.
i now see 1525MHz memory with lower voltage on each card.

also seeing 19~22 MHz on each cards.
learned a lot from this thread.

thanks all!

Hi all,

I got one of these W7100 cards for (relatively) cheap about a month ago.
While looking for some information on how to actually use it I came across this thread, which has been invaluable in helping me tweak this card.

I’m getting 24.5 MH/s out of mine, I’ve modded my bios to these settings: (Using TeamRedMiner 0.8.3)

970 MHz GPU Freq
1650 MEM Freq
81°C Temperature
VDDC 1000mV

I also use Amd Memory Tweaker XL to boost the REF to 30 (from 5) Which takes the hashrate from
~23.5 to 24.5

I’m not 100% sure on the power draw on this. When I pause the miner my power meter goes down by ~150W, but not too sure how accurate this is.

I have this set up in my basement which is usually cold AF, so ymmv with these settings may vary.

I’d like to get the power usage down, and I’d also like to edit the memory straps with hex editor to something similar to what the rx380/285 uses.
Any suggestions welcome!
W7100 is GPU 0 in this picture.

[themisters]

any chance you could post your bios? or just your final tweaks in the editor
