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

[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.

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

[bryza100]

This should be the one, this was in windows rather than HiveOS. Hive wouldnt apply the AMD memory tweak and could only get to 23.5 MHs

Also, this will make your card run hot, and it’s a power hog… still need to get around to tweaking the voltage for this one.

Been following this thread a while, thanks all.

I have a small fleet of these and last night I was modding bios again and was able to reach what I think is a good enough point to share with others. Some of my gpus wouldn’t do 800mhz @ 900mv and others wouldn’t do 1525mhz… so 785 @ 900mv and 1500 it is.

I recommend teamredminer over phoenixminer, it reports an accurate hashrate which is nice and runs with less power, so cooler… Which is great for these cards since their cooling solution is so terrible. Who puts a plastic heat spreader on a professional GPU?

Core - 785mhz @ 900mv, Mem - 1500mhz

DPM 2
MDPM 1
Recommend Fan 100%

Has anyone found the magic trick to cooling these things? I’ve got some that run 70-75c and others that want to push 90+. I’ve re-pasted all of them, I’ve checked the heatsink fin channels, I’ve been going a little crazy with it. I don’t want to invest in new heatsinks for them as much as I know that would do the trick.

[bryza100]

What’s your hashrate for this rom?
Definitely agree about TRM over phoenix.
I also go with 100% fan as well as having a case fan blowing air over it in a cold room.

Perhaps if anyone had access to a high airflow server case, that would improve the cooling for these cards?

[goccat]

Around 21.5 @ 70w per TRM.

Sorry I should have mentioned that.

@stryfe024 Hi friend ,can you please share with me an screen of your settings:

i have the Mistokes18 Bios but only need set your same configurations

[thbh]

Hi what did you use to flash the bios? i’ve bought 12 of these but not having any luck with mining on them

[bryza100]

I think with the latest HiveOS update you can overclock directly in HiveOS. Failing that, use the flash utility built into HiveOS under the overclocking tab. Use tongabiosreader to edit the bios.

I got two 3070s at retail so 2 amd firepro wd7100s fooooor sale! Hmu. Gotta say messing with these puppies make me feel like a seasoned hiveos vet. Lol

has anyone figured out how to undervolt these bios?
I’m able to get 21.5-22 stable from my w7100. These are my settings, but it seems like the processor is the limit, not the memory, the load is only 72% on mem using amd-info.

[DigiB]

I am getting anywhere from 21-32mhs at ~70w depending on my kernel and driver version.
Still trying to figure out how to undervolt with bios hex editing. If anyone has experience with the bios on these tonga gpus some input for voltage settings would be GREATLY APPRECIATED. My goal is to set the bios to default to the lowest voltage settings for core and vram. I can use corectrl on ubuntu but in HIVEOS the undervolt settings don’t stick. (tonga bios reader does not display the correct values for my cards)

[DigiB]

Nevermind I figured it out.

My W1700 with r9 cooler, the best cooler for 15$ keep my temp under 50 degrees.
53.56 mh and 43 degrees.

[alynut99]

[themisters]

where’d you get the cooler? Also, the only miner I’ve seen correctly report the W7100 hashrate is tearmredminer, so you’re likely 1/2 what that is showing unless you are using TRM already.

[alynut99]

Cooler from Radeon R9 290 .
The gpu very stable on 54 mh with phoenixminer .
i try 900clock and 1720 mem - up to 56 mh but after 2 h crash.

I Flashed your bios file but after that vram report in hiveos is over 1000000gb of vram @@ can’t mine anymore
