Yup, pack em together in a zip and i'll modify them

Send me the MSI and XFX one first. I'll do those, you test and then if that succeeds we'll do the rest or try to undervolt even more

I'll send you a pm with my e-mail.

Greetings!

yup thats a great idea

how do you want me to send the rom i could email it as a zip

I basically have all the main brands of 390s

MSI Radeon R9 390 DirectX 12 R9 390 GAMING 8G 8GB 512-Bit GDDR5 PCI Express 3.0 HDCP Ready CrossFireX Support Video Card


XFX Radeon R9 390 DirectX 12 R9-390P-8256 8GB 512-Bit GDDR5 PCI Express 3.0 CrossFireX Support Double Dissipation XXX OC Video Card



ASUS Radeon R9 390 DirectX 12 STRIX-R9390-DC3OC-8GD5-GAMING 8GB 512-Bit GDDR5 PCI Express 3.0 HDCP Ready Video Card



the ASUS cards are beasts they run cool regardless of around 71 degreees and hash at 31mhs stock

the MSI and XFX all run hot and seem to use mroe juice to keep them cool thus the mods required.

PM me your email address and I can send you the ROMs for all the cards

thanks alot !

Sapphire 390 Nitro the one with 1040 stock clock



Hey!

I assume only core voltage mod?
You can reduce the voltage on the mem as well. (Not all cards like that so much though..)

Exactly, got some cards that crash when a monitor is plugged in as well
Further, rock solid!

Greetings

Here are my undervolt stats for some of my various cards.

ASUS 280X @ 1.075V running at 1070/1600
ASUS 7970 @ 1V running at 1000/1575
Gigabyte 7970 @ 1.10V running at 1000/1575
7950 Reference @ 1V running at 1000/1575


All are rock solid stable. You can undervolt further but would have to decrease core clock. All are headless. If you plug in a monitor, it might crash.

What is the brand of the 390 card you do the mod?

Edit: I just found, it is the sapphire as indicated in your file.

Marvell1,

Well, i had a feeling that it wasn't going to work.

With those nano's, it's different, they're all reference designs, so my rom will work on any nano. I'm pretty sure of that.

I didn't know what kind of 390 you have so i just took one of mine.

Could you send me your rom, i'll mod that one and that will definitely work then

Greetings!

Ok this rom did not work on the MSI 390s i have lead to the pc freezing and the card was having errors in dos

i created a boot disk and relashed it back to the default MSI ROM and it worked. 

It seems that its harder to flash ROMs from different card brands to other brands really sucks

** edit flashing from dos seems to be working now**

tried to load your bios to my MSI 390 using AtiWinFlash and I get a SYSTEM mistmatch error never seen that before on flashing

i made a backup of the bios from another MSI 390 and flashed it to the card that would not work with your 100 100 bios and it works any ideas ?

ok trying right now thanks will post update in a few

these 390s I have the MSI does not seem to have a toggle bios switch

Sure.

Try this one first.

-100mV both Core and Mem

Link

If it's stable, i'll lower it some more


Greetings

looks great ill try these on my MSI 390s tonight, can you create one with a default core voltage reduction of 100 as well

thanks !

Hey Marvell1,

Thx for the nice words.

I went ahead and did a small mod on one of my 390's (NON X) rom.

There are 2 roms in this pack.
one with -100mV on the memory voltage
and one with -150mV.

Core voltage is still stock (you can change this with trixx or afterburner.)
Core clock = 1040
Mem clock = 1500

Make sure to use your backup rom position.

Good luck and have fun!

Thanks for the response on this Eliovp , please do some of your brillaint work on the 390s they seem to be great cards not as good as the nano in saphire Trixx it seems you can lower thier
voltage all the way down to -200mv although it starts to climb back up.  Also with lower memory freqency and voltage like you did for the nanos they would be even better.

Ill try you new Rom on the six nanos i have but i have around 23 390s lol

by in bulk how many did you buy to recive a voloume discount ?

The 280x consumes more energy than the nano, ie less efficient. So it will make a loss earlier than nano.

Just have a look at the numbers, it's not worth the time and the investments.

The maxwell architecture it's more balanced right now, I'm very curious about the gtx 1080 performance because given these behaviours we could have a game-changing model. Even if the 1080 will achieve the gtx 980Ti performance, consuming 35% less W with a similar price, it would be a better choice.

It's not relevant the electricity price, it's relevant the USD income of a 5k EUR platform. Not even 15$ net, I consider it a total failure, especially because of the situation will worsen over time.

If I need to invest such amounts, I would prefer right now to build 6x280x platforms, and invest in the meantime in renewable energy sources. The best way to go, especially considering the EUR purchase price of 280x models, and the general performance with the algos. The nano, right now, it's "too little, too late"

The electricity price you use is  $0.3/kWh. I think the cost is mostly below $0.2. Maybe in Germany, it is that expensive.

Thank you Eliovp

The main issue is that the avg profitability with the current ETH and DCR USD value, too low to let the nano's be a good buy at the market prices. With a bulk order obviously the situation is a bit better, but right now here's the situation:

reference data: 6 NANO's in a single system, USD values, electricity cost 0.3$:

power consumption: 0.57KWh
24h gross profit ETH: 11.04
24h electricity cost: 4.1
24h gross NET profit ETH: 6.94

power consumption: 1.1KWh
24h gross profit ETH+DCR: 15.47
24h electricity cost: 7.92
24h gross NET profit ETH+DCR: 7.55

total cost of the platform in USD: 4397
linear break even NOT considering the electricity (ETH+DCR), in days: 284
linear break even considering the electricity, in days: 582

a "BIT" too much.. Even with an electricity cost of 0.10$/KWh we've got:

power consumption: 0.57KWh
24h gross profit ETH: 11.04
24h electricity cost: 1.368
24h gross NET profit ETH: 9.67

power consumption: 1.1KWh
24h gross profit ETH+DCR: 15.47
24h electricity cost: 2.64
24h gross NET profit ETH+DCR: 12.83

total cost of the platform in USD: 4397
linear break even NOT considering the electricity (ETH+DCR), in days: 284
linear break even considering the electricity, in days: 343

I live in Italy and to obtain 0.1$ I should spend at least 35k EUR to produce electricity with solar panels and wind turbines.

That's why I've stopped to go on with the nano's project, too un-optimized, too weak, too expensive, and finally too late considering the polaris and pascal architecture in a couple of months. What you could gain now it's a tiny fraction of the devaluation of the nano's, in the meantime.

To me, it's a failed project right now, with the current USD profit capabilities. Better to go on with nvidia ones in all honesty.

Had a dead Nano a few weeks ago, was flashed with my modified rom.
I switched the switch back to the original position.

Sent it out, received a new one without questions.


Further, Ridiculous expensive? Depends on what you call expensive.

I bought in bulk, got a very nice price (same as a 390x).
So if i ever resell, i could even make a profit out of that as well
