I missed out on testing v9.7 but v9.8 made all my Polaris based machines unstable. After a few crashes I had to use DDU and reinstall the driver because Windows failed to boot.
I guess this is because I have been using up-to-date drivers which effectively disabled the hardware-control/monitor features of older miner versions but v9.8 was updated to the new API.

So, I wish to reiterate my long-standing request: an option to run this miner software with completely disabled hardware-access.

Let's face it. AMD's API has been and will be utter sh|t. Let's not fight it unnecessarily (let Unwinder and other brave souls push through that bush). Sad

Of course, that's always an option. It's just that I installed every second or third iterations since 16.7.x for these RX4xx cards and none of them seemed to make any meaningful difference for mining (neither performance, nor stability), except this one. That's why I thought it's worth reporting. And it's always possible that things like this are not driver issues but a software bug exposed by some otherwise neutral changes in the driver, or they are driver bugs but trivial to work around in software...
7  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's ZCash AMD GPU Miner v9.2 (Windows/Linux) on: December 28, 2016, 12:01:44 PM
There is something strange going on with the 16.12.2 AMD driver (I skipped 16.12.1) and these mining softwares (Claymore ZEC and ETH):
- after a fresh OS boot I rarely (if ever) get all cards (usually 6 per machine) up to full speed, some get stuck at their lowest GPU clock speeds
- restarting the same miner with the same settings usually reproduces the same pattern (the same GPUs remain stuck as before)
- starting a different miner (ETH after stopping ZEC or vice versa) usually draws a different pattern of stuck GPUs (there is overlap but it's not the same)
- starting two processes of the same miner in parallel with 3-3 different cards instead of all 6 usually gets all cards up to full speed
- starting a single process after getting all cards "unstuck" once with parallel processes usually results in all cards running at full speed (even after switching miners)
There is no detectable/reported driver crash (it's no like those card instantly crash and get reset to "safe" speeds, they never get up to full speed).
Sometimes even smaller machines have similar problems, like 1 card getting stuck from 3 (but it's more often for 6 cards and the 3-3 parallel trick is usually enough for 6 cards)

I don't have to check links....I have those cards (11260-01-20G) and on my rigs working only hdmi2vga or hdmi2dvi adapters...
Find some dead HDTV motherboards (from the cheap "untested / not working / sold for parts" category sales, not proper replacement parts). Most of them will have 3 HDMI ports (some might have as much as 5, some might only have a single one but that's rare) which is enough for 3 "rigs" (it's sufficient to have 1 display connected to 1 of the cards per motherboards with Windows>7, I prefer Win10).

Does anybody have a stock BIOS collection for Sapphire RX470 4Gb reference models?

I ran into a rather strange problem:
- bought 5 of these cards (exact same P/N and SKU, roughly similar product numbers)
- saved the full 512Kb image of 1 card as backup (I know, I should have saved them all separately and compare the hashes...)
- flashed a modded 256Kb BIOS (I prepared this in advance, based on the image file on techpowerup)
- noticed something is very wrong with one specific card
- restored the backup BIOS image to all cards
- problem persisted, so I pulled that single card out and used the remaining 4 with my modded BIOS re-applied
- I got the card replaced under warranty (the new one has the same P/N and SKU) but I flashed it, and now it's dead (even after restoring my backup BIOS)

Yes, I know I was stupid I didn't make a unique backup of the replacement card's ROM after the first incident. It's very obvious in hindsight now...
Although, I did always check the memory type with GPU-Z and it always reported Hynix (that's why I was confident I really have identical cards).

Any suggestions?

11  Alternate cryptocurrencies / Mining (Altcoins) / Re: The Correct Way of Powering Your Risers for your RX 470/480 on: September 19, 2016, 07:40:27 PM
Nice warning about those kind of SATA cables. I burned a cable like that when I connected two RX480 cards to a single one of those. But the cable quality wasn't really great to begin with. The wires looked thick enough but the connectors were really loose ("pressured razor blades" kind of fitting in a lazy fashion). Although, 1 card works just fine if the cable quality (including the connectors) is decent (and you don't try to win overclocking contests).

I thought about modifying the risers like that but I ran into a false problem. I though: "nahh, the cards might need the 5V lane, not just the 12V". But I was stupid because I could simply leave the 5V wire as is (on a SATA/molex) and only cut/redirect the 12V. Although, as I said, 1 card per decent SATA cable works just fine for me, so I will leave it be. (But I replaced that PSU with one which has better SATA connectors. The old PSU could be hanging on the balance with 1 card.)
12  Alternate cryptocurrencies / Mining (Altcoins) / Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v7.0 (Windows/Linux) on: September 17, 2016, 09:23:30 PM
Is it possible  that dual SIA mining NOT change hashrate  compared to ETH only?
Or there is something wrong with cards/drivers etc?
Gigabyte 380x.. about 20mhs a card with and without SIA..

Moreover, at some (not large) -dcri values in dual mode you can get a bit more ETH hashrate compared to ETH-only mode (because of shorter queue to memory access), though I see it on 390 cards only.
Increase -dcri and ETH hashrate will fall.

Interesting. I would think the opposite or assume you can use some tricks to achieve the same without the increased power draw (like explicitly flushing or deliberately "starving" that queue).

I don't currently run a secondary coin because high memory clocks with tight timings are only stable at low temperatures (which is also beneficial for power efficiency on it's own) and it's hard to keep the reference 480s cool even at ~100% fan speed if they are busy with two coins. So, single-ETH seems to be better overall (for me, for now. may be winter will change that).
13  Alternate cryptocurrencies / Mining (Altcoins) / Re: Polaris bios editor parameter info on: September 17, 2016, 06:14:06 AM
In order to have less power drain is better decrease the TDP and TDC value ?

Some people often argue they can squeeze out a few Watts decrease by finding the lowest possible PowerLimit (which is an offset applied to the TDP, so you can ignore/disable the PowerLimit offset when you have direct control of the TDP itself), although I think even if such a thing is real (but I think it's just a false perception due to the finite precision and accuracy of their measurements and tuning iterations because TDP ultimately controls [throttles or not] the core clock and very few if anything else, especially under heavy graphic or computing loads when you can't shut down computing blocks) it's not worth worrying about.

If you want the optimal settings I suggest you disable / work around the arbitrary limiters (like TDP) and:
- find the best memory clock + timing pair (not easy but the potential profit is high)
- find the lowest GPU core clock which is sufficient for that memory setting (not too hard but meaningful and thus profitable)
- try to under-volt the GPU core (I didn't manage to do that with the 480 yet, it's not the easiest part in practice)
(Keep in mind that AMD often uses hardware level dynamic voltage scaling since around Hawaii (R9 290X), so the voltage you think you modify is usually an offset for a target.)

Now you probably want to try and create another configuration which allows for lower voltage (loose timings, lower core clock, lower voltage), then compare the perf/Watt of these two configs and decide (or divine a third iteration).
14  Alternate cryptocurrencies / Mining (Altcoins) / Re: Polaris bios editor parameter info on: September 16, 2016, 08:05:05 PM
I personally prefer to eradicate the power limiters (set them high enough to always be a no-op). This is how I run my 480 8Gb cards:

(and you can't see that on this screenshot but I copied the 1626-1750 timings to the 2000+ strap)

It would be nice if I could resize the window so that I could always see every items and their full content in every sub-window.

I must agree too Z170 chipset is having problem with 3+ cards on most boards, its prolly bios related, but who ever is doing testing first disable all non needed IO and internal devices as:
- sound
- ports
- any add in hw as firewire, wifi, etc
- set PCI-e to x1 mode if possible

And only then test it, also better use win10 because it should handle 8 GPU with no moded drivers

Ill give it a try, however i just cannot wrap my head around the fact that the z170 chipset has more pciE lanes compared to the h80 or h97, in every single connectivity feature the z170 is superior to the h97, and somehow the former performs much worse than the later.
I guess that it is a hardware issue, but mostly a uefi issue, so maybe a custom rom or manufaturer update will solve this, however i wasnt able to fin any information of anyone trying to  develop a custom rom for that purpose. And the bios updates do nothing regarding the 6 gpu compatibility issue.

This article alone won't help you fully uncover the whole problem (it's not even directly aimed at this exact issue of miners, just a general analysis):,30210.html
I think the author was on the right track in understanding the SkyLake platform's possible connectivity issues after piecing some important things together but he left the matter alone before a real final conclusion was formed.

I think the real problem is some undisclosed further limitation about how these HSIO lanes can be allocated to PCI-E or other devices:

As you can see, some HSIO lanes are fully or loosely pre-allocated by Intel. Some lanes can be configured as:
- USB only
- PCI-E only
- either PCI-E or USB
- either PCI-E or SATA
- Now look at that Gbe !!!

The weirdest thing on this graph for me is the limitation regarding the (built-in?) Gbe network controller's HSIO lane allocation. I would think it should either act like any other PCI-E device (freely allocated at any open PCI-E capable lane) or have it's unique fix preset like the USB or SATA controllers do (like USB#1 can only go to Lane#1 and SATA#7 can only go to Lane#20, etc). What kind of logic might be hiding behind that?

---> Take note about how you must pick 4 neighboring lanes starting at N*4+1 (like 5,6,7,8 but not 6,7,8,9) for PCI-E 4x devices.
Another strange thing here is how you can theoretically have as much as 5 separate 4x devices (if you are willing to sacrifice all SATA and Gbe but otherwise it's still 4 with 1 Gbe and 1+ SATA), yet only 3 of these kind of 4x devices are allowed to be used simultaneously.

At some point I though I figured this out: I can operate 3 PCI-E cards because I had 5 PCI-E 4x blocks, 1 allocated for SATA and 1 for Gbe (and/or some SATA at the same time), thus leaving me with 3 free PCI-E 4x blocks, all of which are capable of operating a single PCI-E device regardless if that is 1x, 2x or 4x
But... I also had an integrated USB3.1 and a sound controller which are both PCI-E devices! So, this 4x block = 1 device can't be true. Well, unless I was actually operating 2 cards on the PCH and the third one was in the 16x slot and it's wired directly to the CPU (not micro-managed by the PCH - but I think it is because the Z170 motherboards can be configured in 8+8 modes whereas H170 boards are limited to a single 16x slot but this could be an artificial limitation imposed at firmware leve but this would also explain why Z170 seems to handle 4 cards and H170 only 3 cards: it's 2 vs. 1 cards on the "direct" CPU 16 lines and always only 2 on the PCH).

And now, if you thought you almost figured this out as much as it's possible..., look at how SATA#0 and #1 can walk around the table! What does that supposed mean? At this point I am beginning to question if this table exists to shows the fixed limitations (more than the USB ones, that is) or it's merely an example which illustrates several possible (and probably recommended) alternatives at a single graph. So, my weak speculation is destroyed here.


If you are into some experimentation (either by virtue or out of necessity), it would be interesting to hear about any of these C232 or C236 workstation boards (yon don't need Xeon CPU and ECC memory, just plug in your cheap Pentium and regular non-ECC sticks if you wish): (5 slots for moderate price) (6 slots, expensive) (6 slots, expensive!)

With this board you need powered risers. The asrock btc boards have 2x 4pin molexes in the board to give extra power.

I like the Asrock motherboard with the  2x 4pin molexes in the board to give extra power. that is much safer.

You actually need zero molex on the mainboard when you have all the cards on molex powered risers (the BIOS will probably demand it anyway and there is no harm in obeying).
It shouldn't be a problem to run 2 cards sitting directly in 16x slots either (if the PSU has decent quality ATX 24-pin wiring/termination and the motherboard was designed for 2+ graphics cards).

On the other hand, I managed to burn two molex/sata cables and a modular socket on a Be Quiet! PSU while running six RX 480 cards on molex powered risers.
Since the PSU had 5 sockets for sata/molex cables (it was actually 6 but I failed to realize that there is an extra, different looking socket, intended for a short molex cable which is there for motherboards with an extra molex but could be used as any standard molex...) and I had 6 cards, I decided to connect 2 cards per cables (6 risers to 3 cables in total).
At first, one of the modular sockets melted a bit with the cable connector getting badly burned in it. (It was still running but I noticed the smell, so turned it off and started investigating.)
Since the other 2 cables looked perfectly fine I thought it was a random fault (either I failed to push it into the socket properly, or the connector was faulty to begin with, etc). I was down to 4 functional sockets in total anyway (well, actually 5, though I believed it's only 4 but it was less than 6 now anyhow), I didn't really have a better choice but to pick another cable and continue to run with 2 risers per cables.
The next time I noticed some smell again, turned it off, and saw as another sata/molex cable (with 2 risers on it) started to burn out. This time, the socket on the PSU remained intact but the cable started to loose it's coating and the SATA plug itself was really hot.

So, these modular sata/molex sockets/cables are clearly not ready to handle this kind of load (2x75W or whatever these cards might eat from the PCI-E slot).
The PCI-E, CPU and most of the ATX 24-pin wires seem to be significantly thicker than these sata/molex wires. The former group of wires go from point-to-point, directly terminated at both ends while the latter ones are "chained" in a way which is (in hindsight) clearly not ready to handle this kind of load (it's basically a single long cable and all the SATA/molex plugs are simply pressed on them, cutting through the insulation and keeping the metallic contact thorough "pressured razor blade" kind of fashion).
It's also notable that the extra short molex, intended for direct motherboard connection, is also point-to-point, directly terminated at both ends (not a razor blade pressured and chain-able kind like all the rest).

The TL;DR lesson is that even though the ATX 24-pin connector/cable clearly has it's own limits, the sata/molex cables intended for hard/optical drives can be significantly weaker.

I recently replaced that PSU and wired the new one with 1 card per molex/sata cable from the beginning (it has 6 identical sockets for these kind of cables). I will probably use the slightly damaged PSU with 3 or 4 cards at max later on (when I will have some fresh mining profit to reinvest).

I wonder if anybody tried the workstation counterparts of the B150 and H170, namely and respectively the C232 and C236 chipset based boards (these are probably the exact same silicon but with microcode support enabled for some entry level E3V5 Xeon CPUs and ECC memory [when the Xeon or Pentium/Core CPU also supports ECC] on top of the "lesser" consumer CPU and memory parts).

These boards aren't exactly cheap in general (but neither too expensive compared to some of the "fancier" consumer parts, especially if they live up to their promise of being more stable and reliable than their consumer counterparts) and I am yet to see any SKU with >5 PCI-E slots (they might restrict the numbers on these boards for an inherent reason rather than wiring up countless slots regardless if they will work or not Cheesy) but they might worth a closer look and try (search for a relatively cheap one with >4 slots, =6 if any and give it a try...).

4/6 was possible depending on the right slot assignment and UEFI Setup configuration but it wasn't really stable under mining load for longer periods.
5/6 was a disaster: the misbehaving SATA controller caused data corruption on the root filesystem up to the point where Windows became unbootable.
6/6 was better, it didn't even get through the firmware initialization, so it had no chance of corrupting data on the SATA drive.

I took it back to the store and left with a 6-slot Gigabyte Z97 Gaming 3 (v1.1) because they had one of those at stock. It works great so far (and it looks like a decent PC mainboard unlike those 80/90-series 6-slot Asrock boards, so it might be easier to sell when the time comes...).

- I planned to use Gentoo (which I love) but amdgpu-pro is not available for it yet (well, not in a working condition) and amdgpu+MESA instantly crashes with ethminer (claymore refuses to use MESA).
- then I tried to fall back to Ubuntu (which I hate) but I had some issues with amdgpu-pro (and since I hate debugging Ubuntu problems, I gave up fast)
- finally, I settled for Win10 (which I like and prefer over Win7)
I quickly checked the hashrate in Win7 but saw no meaningful difference compared to Win10, so I was pleased the Windows line is not restricted with these cards.

secure boot is off of course in my system
so you suggest to enable IGPU, sign driver myself, then turn testmode off and that's all?

- turn on the iGPU (set it to Auto if possible, so it's always disabled when you don't connect any monitors to it but enabled whenever you do)
- move your monitor to the iGPU (you might loose the signal on the discrete cards anyway and you might need to do this temporarily to stop the AMD driver from loading)
- have an AMD driver installed (doesn't matter if already "cracked" or stock but I will assume stock here)
- flash your cards with custom BIOS (if not already)
- reboot to Safe Mode to replace the DLL file with the cracked one (if not already)
- enable the Test Mode with bcdedit permanently for every regular boot (and keep it enabled indefinitely) and reboot
- sign your DLL file with the tool linked above (preferably while in Test Mode but with the driver NOT loaded, either due to signature problem or no cards connected, etc...)

My exact journey was like this:
- flashed the cards
- enabled Test Mode for regular boots
- rebooted to Safe More (note: not Test Mode yet) and applied the cracked DLL
- tried but failed to reboot into Test Mode (I ended up with a completely blank display, no life sign)
- moved the monitor to the iGPU and rebooted again into Test Mode (by default)
- I signed the cracked driver with the linked tool
- rebooted (yet again into Test Mode as always from now) and saw the AMD driver loaded
- I shut down Windows, move the monitor back to the discrete AMD card (for WattMan to work), booted (into Test Mode) and everything works
