Topic: R9 Nano Modded Rom - page 17. (Read 60873 times)

Hmmm.... so I should not use this Nitro ROM mod on my MSI R9 390? This also have a backplate....

Talan,

Thx for that register dump.

Now try this one.

Flash it, completely shut down your system (Turn off the electricity!), completely remove driver (DDU), reinstall driver, remove Afterburner profiles, run afterburner and slightly go down on the core voltage (steps of -6mV)
This one has -75mV VDDC and -75mV MVDDC. so basically you can still go to -100mV if you lower your core voltage in afterburner to -25mV. Your system will be already booted and won't be going crazy like it is right now.

If this works, let me know, i'll lower the memory voltage until you hit the sweet spot.


For all you other guys out there.

Here, R9390Nitro With Backplate modded rom that i'm using.

This rom will make your nitro into a power hungry beast so please be careful.
First run stock clocks(after the flash), if it's ok, raise your core voltage with little steps (+6mV).
DO NOT flash this rom on any other R9 390 brand. It will definitely screw it up!
So ONLY R9 390 Nitro with backplate.

Also.

This is a modified bios. Yeah...
This will void your warranty.
I am not responsible for a failed bios flash or damaged card resulting in the usage of this bios.
By downloading this you are agreeing that you take full responsibility for using this bios and hold no liability to me or this site.
If you feel uncomfortable, than don't.
If for some reason you do brick your card, because you probably didn't read my instructions to careful :p and you can't afford another one, than don't..
If you're happy with everything as it is right now, than don't.
If you're like me, and you want to get the most out of your GPU's. Than yeah. go ahead..
This goes for every bios i share.


Greetings!

Hi there - can you share the r9 390 sapphire nitro rom with us - that will be useful
Thanks in advance!

Hi all,

Thanks for the feedback. I ran some further tests today but still no solution found.

That's what I did:
- Tested Gen1 for Pcie: No change. I used to select Gen2 so far.
- Disabled onboard GPU: No change, except that I used the nano for the output

- Flashed -175mv rom. Reinstalled drivers after ddu. Windows reports "Your driver has crashed" in the taskbar. System is very laggy.
- Added a Radeon 390 used for the output which is not underclocked. 2 Nanos plugged in. No monitor attached to them. Windows runs stable now. Ran afterburner, changed to 1000mhz core for the nanos. Ran claymore miner. PC immediately freezed. Had to hard-reset.
- Flashed -100mv rom. Did the same above. Same result.
- Tried a Saphire Nano. Flashed -100mv. Same result.

Here's my system config (all NEW items which I just bought).
- AsRock BTC Pro H81 with 8GB RAM and CPU
- SSD
- eVGA 1300 Watt PSU. At max I ran 3 GPUs. PSU should not be an issue.
- Powered Risers
- XFX R9 Nanos
- Virgin Windows 10 installation.

Here's the register dump from AIDA64: http://speedy.sh/hNsKt/atigpureg.txt

Any further ideas? It's really starting to piss me off as I put so much time into this issue and still no progress.

But thanks so much for your ideas so far!

I have no problem running this modded Bios except that I need to have monitor attached to show the core/mem/etc.  With monitor plugged in, I can clock to 1000MHz core without any issue.
By the way, I'm running with 2 Nano, one Sapphire, one XFX.  Right now my secondary monitor is plugged into XFX, while Sapphire without monitor.  I'm able to see both cards' core/mem/etc.
And I have onboard VGA enabled, plugged in to my first monitor.  I need a display, so I use my onboard VGA.  I didn't face this problem with Nvidia card though.

To be safe, if there is an option, I always set the PCIE generation to 1, that will make the system more stable.

I can only think of 2 things really. Or you've not disabled onboard vga in your bios settings. Or it's the driver(which i doubt as i tested several drivers..).


Hey Talan,

A dump of your rom wouldn't help. As it does not matter which one you use because they're all reference designs and my rom should work on any nano out there. (at the time of writing).

Again, i have a strong feeling that you guys haven't turned off the onboard vga. As that is the only way i have experienced this kind of issue in the past (afterburner and gpu-z not showing everything..)

As said before, i use 16.1.1 and 16.4.1 drivers on my nano rigs. They both work perfect, no monitor attached, everything works as it should.

The increasing of the core clock from 800 to 900 and it freezing is another story, that definitely shouldn't happen as i can raise my core clock to 1000 with an undervolt of -100mV VDDC without any problems at all.

That points out in your PSU failing for some reason, or the way you powered your risers or something.

Does your card freeze? Or does the complete system freezes and just reboots?
What exactly does it do?

Really sounds like a power problem.

You could do a register dump with AIDA64 (install it, click view, enable bottom toolbar, right click left bottom corner, video registers, ati/amd register dump "with 1 card attached to mobo") and show me that dump.
That'll explain some things as well.


For my MSI motherboards i had to set them to GEN1 as well, or they wouldn't recognize all 6 cards.

For my Asrock H81 btc boards i did not have to do this, recognizes all 6  of them directly.

Greetings!

In your motherboard BIOS, can you set the PCIE generation to be 1 or 2? For my MB, I set them to 1.

Hi lawrencelyl and Eliovp,

I did many tests today- but still the same issue. First of all, you are right, lawrencelyl, this situation is even there with the stock bios. So it's not a mod issue.

I've been running tests today by running it in win7,win8 and win10. all clean installs. driver left and right. I now doubt it's a driver issue.
When core clock increase, the system gets very unstable. As mentioned, nano crashes when I increase the core clock from 800 to 900. I even tried to increase the core clock by 50mV.

@lawrencelyl : Can you run the bios mod with monitor plugged in? What are your settings in afterburner and which mem clock mod are you running? Are you on XFX?

At the beginning I thought it's due to the monitor. Or could it be another issue?
Eliovp, would a snapshot of my stock bios somehow help you to see if we now have a fundamental difference? Let me know.
I'll run some more tests next week, but not many ideas left what to try...

Cheers,
Talan

I have the same issue as you with my Nano.  Even on stock Bios is the same.  I gave up troubleshooting so I just plug in monitor

Bookmart it
i will buy sapphire R9 390 nano in next monday

No problem.

What driver are you using?

i've got several rigs (6 gpu's though), all nano's, and none of them give me that issue.

I can easily open up gpu-z/afterburner to check/modify all the needed info.

As well as setting core clock to 1000 without any problems.

I have the same motherboard, i just use stock settings.

To be honest, i have no idea what's going on.

I use Crimson 16.1.1 on 95% of my rigs, i have a few that are running with 16.4.1, no issues at all.

So the only thing i can think of is the driver.

Oh, and on stock rom, you do not have this problem? I assume not.

Flash the modded rom to the first bios switch position. That is also something you can try.
No worries, you can always flash back (booting up in windows from the other switch position, when booted, switch it, flash it and it's back to the original).

Could be true, but i kind of doubt it. But maybe..


Don't think i was talking about an XFX version

I have a "Reference" 390 modded rom, with vddc offset.

But no, my XFX Black dissipation does not have MVDDC offset, neither can it be added in the rom.


Could you hook me up on IRC or something? So that we can work this out.

Shouldn't happen, those errors.

Or perhaps you've sorted it out already?

Let me know.

Greetings

If you want the Nano to run 900 MHz instead of 800 MHz "stock", you might have to increase the core voltage by 10 or 20 or even higher mV.

Hi, Thanks much for your answer.
I completely uninstalled everything. Even with DDU.

However, the following still happens: When no monitor plugged in on the nano, then no data in gpu-z/afterburner is shown. Once plugged in, core/mem clock + temp immediately show up in gpu-z/afterburner.
Of course, with monitor the overclocking capabilities of the core from 800 to above 900 fails and the gpu crashes.
What am I missing here?
I am using the AsRock H81 Pro BTC as mainboard. Any wrong BIOS settings? I also put the gpu directly on the MB without riser. Same result.
Btw someone else had the same issue in this thread. But no result was posted.

Let me know if you have some more ideas.
Thank you!

Does that XFX rom have memory voltage mod? Not the memory controller mod. Do you use the offset?

Will comment on that later mate, or perhaps help you out, but gotta go now, already late again for a meeting.

I have a rom for a 390(reference "hard to find") and will share another one that's running on my nitro's as soon as possible!

Greetings!

Eliovp.... done -100Mv/1050/1125.... 5x390=151MHs.
Do you happen to have a ROM mod for R9-390?

Btw, I have my Nanos in, I haven't spent time on the applying your mod yet. My first attempt gave me an error "GPU not found", when I ran the atiflash command with the parameters in your guide. I stopped there and will spend a longer weekend to do more reading. Any ideas? https://bitcointalksearch.org/topic/m.14946664

Try 1125, 1200 is a weird number in case of your timings.

1500 or 1375 or 1250 or 1125 is more like it

You also saved 20% electricity on the memory parts as the power consumption is linearly proportional to the operating frequency.

Thanks - works like a champ!
