most of the mods are "algo-optimised" - no good 4 profit-switcher.

 

Do you know any details of the mod? I have 470s (non MSI) so its hard to find a rom. So far I´ve only done the 1500er strap mod by myself but I´d like to save some power of course ;-)

really ? - I use 16.10.3 - works fine with RX-4x0 and R9 390 - even 4 gaming

What is SM Linux? Not using Boysie's, using Jukebox's bios. I would *love* to use Linux (it's what i'm most comfortable with) but the power saving from using Windows means at this point I don't have much choice unless I can somehow figure out how to do -100 mV drop for each GPU.

the current SM Linux @ 6x480 @ 730watts with Heliox rom is running well and integrated with Claymore Ethman monitoring so I am happy with that.

I probably consider your approach too (Boysie's rom?) further power savings but my intention is to move away from Windows as much as possible.

No plans to dismantle this rig since its already ROIed -- but all future build will default to the 4GPU build.

Without using his low-power rom and using a different one, I have a 6 card rx480 rig doing > 29.1MH/s for each card pulling total 882w at the wall.
That is using Windows and the rom and applying -100 mV drop and it's rock solid (also Biostar motherboard).

That adds a lot of savings when you have multiple rigs!

After the ROM mod, trying to attempt any finetuning in AB 4.2 or 4.3 will crash the rig or become unstable.

For 480 case, messing with wattman is no picnic too and I could only get 33% reduction in -mV.

But using the ROM mod as it is, can already achieve 29MHs, low power - just under 1000w for 6xGPUs and considerably less heat.

Putting this same rig but under Linux (ethOS or SM), kill-o-watt show 730w for the same rig.

Both systems if mining ETH with Claymore 7.4 Windows or Linux achieve same 29MHs per GPU.

Without ROM mod, and just -100mV or -96mV with AB, with 6xGPUs, just under 1200watts in Windows.

Did not try Linux at that time because I havent tried ethOS or SM or meddling with AMD drivers in Ubuntu was just too complicated for me.

Until this guy called Heliox got his Nanos modded and shared with members....

Yes, all my Nanos are also modded with Heliox rom mods but I could manage only the -100mV version in which was already a saving in power but could have done more.

My only GPUs that are not modded and yet the best performer currently are the MSI 390s - solid like a rock, finetuned with AB4.2 -96mV and OCed slightly, delivering 30MHs per GPU in ETH. Solid in XMR and ZEC too.

The only downside are 390s are power hoggers and all 5 rigs (5xGPU x 5 rigs) uses 1600w EVGA-G2s which cost me a fortune.

Thats why I am never going back that alley and stick to the 4-GPU Biostar Z170 gold standard like Phils for future builds.... unless Panda Miner becomes a reality.

Under windows you can lower power consumption considerably with Trixx or Afterburner. I'm trying to gauge how you come to the conclusion that Linux uses less power than Windows.

the RX480s were originally mining ETH during ETH hey days

All my 65 x RX480s are modded with "29MH480LowEnergyOK.rom" from Heliox/Eliovp

Used the same cards on ZEC and XMR, in addition to ETH with no issues and still achieve good wattage.

Settings on Linux is at "stock" no settings in simplemining or ethOS.

RX480, Win10 on XMR v9.6 -- use Crimson 16.11.3 or 4 to stabilise the rig.

Claymore need to improve the Polaris support for v9.6 miner

Win 10, 2 rigs with 10x RX 480 cards total

Claymore's XMR miner works 3-5 minutes and stopped

So have to stick to ETC

Yup, XMR all the way.


Please explain how you managed to save power using Linux when you can not do -mV drop.

Hope everyone is making money on XMR -- all my 33 rigs are on Dwarfpool XMR.

Here is something to share, and hope it will save you time and effort...

Before this all the GPU rigs are on ZEC, ETH and XMR, spread across Nanos, 390s and 480s.

During the full swing to XMR, 3 rigs started to act up and I think its riser and driver related....

During ZEC, ETH mining -- the rigs are very solid and stable, good drivers and optimised speed, basically running well to my satisfaction.... but its suddenly not stable on XMR (working well before)

Instead of trying to meddle with Windows and Crimson drivers to make it work - I decided to use the magic sub stick which have saved me countless of midnight oil sessions before.

If you have not heard of simplemining.net before, suggest you visit his page.

My farm is all Windows due to learning curve on Linux and also poor AMD driver support in Ubuntu, etc.

My long term goal is move to all Linux for stability and further power savings (6x480 takes 1000watts on Windows, but only 730watts on Linux)

OK back to the usb solution, burn an image on a usb stick (prefer on usb3 for speed) from simplemining.net. Choose your image; RX (amdpro driver) or Non-RX (fglrx driver).

It will self update to latest version and start mining as per your miner app of choice in the master web console.

This fix got all 3 rigs to mine to Dwarf using Wolf XMR Linux miner which is very stable. You can also use Claymore but its using outdated v9.1 Linux build.

Anyways, this saved me a lot of time.... indicating that if it didnt work in the first place... and working now with Linux.... then the culprit can only be Windows... not the riser.

Good mining everyone.

got busy  sorry.

before I forget my new evga board is acting up.  so I kind of think only the biostar is good.

Didn't received it !

Thank you Phil,
Unfortunately, I can't find any of the 3 MB at a decent price in any EU country
Almost the same (or worse) as ordering in the US and paying shipping + customs...

16.9.2 works best for me (RX400)

 ANY Relive (16.12.x) version to date has been very poor for mining - they don't get along with modded BIOS at all, and they impact hashrates NEGATIVELY by 5-10% in my testing on them.

 I recommend 16.10.1 (most recent WQHL version that isn't Relive), but 16.9.2 also worked well in my testing, and I suspect any 16.9 16.10 or 16.11 version will have competative results.

 15.12 is still a viable "go-to" version for pre-RX series cards but I've not found there to be any difference between that version and 16.10.1 on hashrates for my various R9 2xx and HD7xxx series cards.
 Definitely worth going to 16.10.1 if you ever plan to upgrade from older cards to the RX 4xxx series.

Thanks Phil... sounds good to me since we are running mostly the exact same GPUs.  I can't remember... are you on Windows 7 or 10?
