134 Mh/s @ 2.25A, 495watt (6 Cards) stock settings rom

185 Mh/s @ 4.8A, 1050 watt (6 Cards) 1020 Core, 300 Mem

so the stock rom only 22mhs for each R9 Nano ?
it's very small hash , how much the based clock ?

Stock modded rom = 22Mh/s because the core clock is set at 800 to reduce electricity usage.

You can up that core clock to 1000 and you'll be hashing at around 30Mh/s.

if i mod ROM of my R9 NANO, the guarantee will be broken too?

Yes, your warranty will be broken. (I had to send a few back, Nano's, they were flashed as well, i got them back replaced brand new. so basically it depends on manufacturer.. )

Which memory frequency strap did you change, where do you get the mod memory frequency? Or How do you decide the strap?

Used The Stilt's 1250MHz timings for the 1126-1250 strap, The Stilt's 1250 Timings for the 1251-1375 strap and the 1375MHz Stilt timings for the 1376-1500 strap.

What do you mean with "where do you get the mod memory frequency?
Same with last question, don't really know what you mean by that mate..

When you under volt, do you just change the base voltage to 800 mV or lower? Do you have one for XFX?

No i don't, i add an offset of "for example" -25mV to the rom so that voltage (VDDC) is added to all DPM states or reduced from all DPM states.

In this case the voltage controller dynamically changes the voltage (as it is also when stock rom).
But now of course with a reduced (or raised in this case) standard VDDC that i set in the rom itself.

Thanks a lot!
can you also post the number are you getting with these in terms of hash at clocks you use and power draw - if you did measurments

I should do retest because i can't remember what the numbers were.

How do you change the R9 390 memory timing? Do you copy the 800MHz timing to replace the 1000 MHz ones?

Can you mod for an undervolt one - that is especially important for this power hungry r9 390?

I'll post an undervolted one later today.

Thanks for your answer, Eliovp!
I tested with only one Nano connected. Directly plugged into the Motherboard -before that I used powered riser. I have no molex plugged into the motherboard (which should be fine as I have only one card connected and if more, only via powered riser).

As a power supply, I use the ESVGA 1300 Watt. Completely new with one dedicated rail for each gpu. Otherwise there's only the HDD and mainboard that uses power. That definitely should be sufficient.
The Motherboard is H81 btc. I updated to the latest firmware...

What AMD driver version are you running?
I will run some tests tomorrow, but there are not many options left.

Cheers,
Talan

I'm running 16.1.1, 16.4.1 and 16.5.3

All doing perfectly fine!

I however run my 6 nano rigs with a LEPA G1700 (and a few G1600's).
But your setup seems to be okay.

Good luck with the tests, i seriously hope you figure it out!

There must be a reason why it's failing. It's just finding it that can sometimes be a struggle.

Talan,

From what i read there. (System freezing)

You have a power issue.

I've got over 100 Nano's, there's isn't a single one that can't handle 1000 core @ -100mV VDDC.

Obviously 800 core will run fine, it consumes practically nothing :p

If you raise your core clock, your power usage will go up. And not by a little, it will go up a lot if you compare it to 800 core clock.

So again, you're experiencing power issues.

How many nano's was that? 2, 3?
What kind of power supply do you use?
How did you connect your PCI power cables to your PSU? (2 on the same rail can cause it to crash..)
Have you tried just running 1 (1 connected to your motherboard "without a riser")?
What kind of motherboard is that? H81 pro btc? Molex connectors connected to the motherboard if you use non powered risers? Or if they're powered risers, than don't connect those molex connectors..

I can sum up so many things..

you'll have to figure out where it's going wrong mate..

Greetings!

Can you tell us a bit more, about the rom?

+43.75mV VDDC.
Maximum TDP has been raised
Power limit has been raised
TDC limit has been raised
Fan profile adjusted
Slightly different timings.

So what is this rom exactly in terms of parameters - I thought it was undervolt one?

Check above..

Nope, this is not an undervolted one. With an undervolt it is impossible to reach +32-33Mh, let alone 38-39.. (Ethereum).

Do you have a version of this Bios that will work on a Asus r9 390 strix?

Your work is much appreciated!

Sorry i don't, as i don't own that card

Hi Eliovp,

I tried your ROM but it shows the same effect. I was able to change the core to 900mhz but once I started claymore's miner, the whole system crashed.

I really wonder why no other experiences this issue. What's your program to display your remote desktop? I use ultraVNC. I somehow suspect that the system still uses the GPU to render the remote desktop and causes the issue. Again, once I use internal graphics, no core/mem clock is shown in afterburner and I can't change the core to 1000.

Before I flashed the 75/75 rom, I just let it mine with the -100mv mem@800mhz bios and it worked @ 22mhz. Of course, I want to reach the 30mhz...
Do you think it can be due to asics quality?....

Talan,

Thx for that register dump.

Now try this one.

Link

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.
