OP, in the XFX BIOS, how do you change the memory voltage?

Does the memory voltage change when the frequency change, like the VCore?

i change it by adding the vddc and mvddc offset in the rom, this because it's standard not there.

Same goes for Fiji, VDDC and MVDDC offset are not standard in the rom, i had to add those myself.

The voltage changes when the frequency changes yes. In other words, that voltage is reduced from every DPM state. Unlike changing every DPM state manually, the voltage controller does this automatically in my case Smiley


So the MVDDC changes when the memory frequency changes? If the frequency is reduced from 1500 MHz to 1000 MHz, how much voltage change?

You may right on the number of VGA cables, I need to check the PSU later tonight otherwise this 8 GPU monster even using the mod will need 2 x PSUs because of lack of cables points.
You mean PCI power cables right? Smiley

You'll probably need 2 PSU's yes Smiley

ellovp - have you tried 8 x GPU setup.

I am thinking of doing this using 3 to 1 PCI riser on the 6th PCI slot.

That should get the MHs above 200MHs per rig.

Thoughts?

I am going using Claymore Dual miner for this rig.

thanks

I haven't tried with my nano's, i have tried to use a pci hub/splitter in the past, i still have 2 of them though.

Maybe i'll play with them again sooner or later.

But like it is now, 6 per rig is more than enough Smiley

+ i would need an extra PSU.. nahh i'm fine like this :p

I have EVGA 1600w G2, and I will work on the 8 x GPU version (246MH/s rig!!!) - I will post results soon.

I am still waiting for DHL to knock on my door...

I don't think you'll have enough PCI power connectors to connect all 8 Gpu's.... "could be wrong though.."

Anyhow, even if you do, the psu won't be able to bring enough power to all those rails. "again, could be wrong.."


I tried latest driver 16.5.2, still the same behavior.  May I know which driver are you using?
Try to boot with only 1 nano connected to your mobo and see what that gives you Smiley

A side question, for the R9 Nano, if I'm running headless, I can't seem to view the core clock/memory clock/temperature/etc.  Only able to see them with monitor attached.
Is there any workaround to view them when running headless?  By the way, I'm on Win10.  Thanks.

Impressive power efficiency.

However, at this point I don't see a reason to choose Nano due to its extremely high cost.

If it were cheaper, I'd totally be game.

just bought a couple of Nanos for a new ETh rig - cant wait to squeeze the daylights out of this brats with your mods...

.... so which one should I go for? Both looks good - with its own pros-cons....

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

OR

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

I think I will go for 185 MH/s on a 1300 PSU.

Anybody have any list of "dos and donts" before I do this ?

Hey Citronick.

Try the lower ones first.
link: Here "-100mV mvddc to -150

or the ones that work on every nano and that have helped a few others that i got messages from in PM.
link: Here "-50mV mvddc & -100

Start flashing with the -106mV mvddc and slightly go down.

You can do a registerdump with AIDA64 and check out the voltage that is needed for your card to achieve 1000 core clock.
The higher that voltage is, the higher your leakage of your card is and the lower the asic quality is.

In other words, if your card doesn't need a lot of voltage to achieve that power. You can go ahead and flash -150, -175mV mvddc.

"they're all -100mV Core clock."

Greetings!




thanks - good points - yes i will go through step by step, these are expensive items so I wouldn't want to brick it

Wow 100 of these babies would be sweet..... open rig or hosted DC?

Open,

You can see them "here"

greetings

You'll have to do crazy things to brick one Smiley

Again, as i mentioned before, got 100 of those, flashed them all individually more than 3 times Smiley They're all still running at max 60 degrees Smiley

Sounds like a driver issue, all my rigs are headless and i can monitor everything without a problem. Also Windows 10.

Reinstall drivers mate. That'll probably solve it Smiley
That's weird.  I have tried to reinstall driver but still the same.  Using 16.5.1 driver.
I have other Nvidia cards on the same rig but I don't think that has to do with it coz I did try to remove Nvidia cards but still the same.
Maybe I should try other driver versions...

That is great effort. Are you going to release your XFX R9 390 BIOS mod soon? We are looking forward to it.

As soon as i can :p

Got so many things that i still have to do these days. I wouldn't mind a few days with more than 24hrs in it :p

What about your experience with "intensity" in ethereum mining config? 800 core and 300 mem of course...

What exactly do you mean by that agente?

In the Claymore miner, there is ethi setting, that determine the intensity of the mining. I think he means that.
