Topic: R9 Nano Modded Rom - page 19. (Read 60873 times)

okay I have a rig with 2 r9 nanos and 1 r9 390

this is my premium rig  it does about 77mh at about 600 watts.

I know this is good,but I am looking for better.

this is done with msi afterburner

the nanos are
 -100
  1000 freq clock
  500 freq clock

the r9 390

is

-100 clock
1000 freq clock gpu
1250  freq clock memory

a 760 watt plat corsair
dd4r4 low volt ram
a m2 ssd
a biostar z170 mobo
an i5 -6500t cpu

this mobo can do 4 cards if they were all nano so I have a few options to improve this board.

I have a 3rd nano I could add it and add a r9 380   it would all fit.

but I really want to know how low are you getting the nanos to do lets say 26mh a nano

can you get them to 170 watts and do 26mh with the mods / flash

this is one of the many guides i stumbled on my journey's.. Its very nice. http://www.techpowerup.com/forums/threads/amd-ati-flashing-guide.212849/

check my previous post for edit.. Also are you booting into dos. or is this at windows command prompt
you have to be in dos only for atiflash to work and i dont trust winflash for this operation.

Best Regards

same error... strange.... but I can see them on TRIXX and Device Manager

Citronick.

Try atiflash -i or -ai and make sure the devices are being listed at the dos prompt.. your command line looks correct.  no it is wrong my bad

a -f -p 0 DPM-100mV.rom

first run the command above making sure you assign the right slot with the -p command.. its either going to be slot 1 or 0

I have a "Adapter not found" error message, after attempting "atiflash -p -f 0 DPM-100mV.rom" at command prompt.
But in device manager, both of the Nanos are present. The first Nano is on the 16x slot without riser, and the second one on PCI-USB riser on slot 0. My environment is W8.1, Asrock H81 BTC board, Celeron 1840 and 8GB RAM. Any advise?

Ive been having this problem too, from what i have tested on stock ROM with afterburner - voltage -100mv and a power limit of like 5-10% will run the cards at 1000mhz stock. They get throttled hard by running hot though. The cooler you can keep them the faster they will be able to run. My cards this way use 950 watts on corsair Link. Has speed on cards varies, because they are getting hot between 62C-70C. Cool ones run 28mh, hot ones 23-25mh/s.

I've messed with flashing quite a bit. I have not been able to get a 1000mhz clock. I have 5 XFX nanos/H81 BTC pro/ax1500i PSU/i5/windows 8.1/Powered USB risers and 1 card on the board. I flashed with the mildest ROM, I think the -100mV.ROM. If in afterburner i put voltage at +50 and power limit at +25% I can get the cards to run at like 920Mhz. Any more than that and the screen lags and I get black screen flashes until the whole thing crashes. Im running 16.1 drivers. This is running with a monitor attached, but not turned on. IIve been using google chrome remote desktop. If I try to do it powering a monitor it will crash out at like 815mhz instead of 915. I turned all appearance settings to performance in control panel. Running like this im using I think 600-650 watts and getting 27Mh/s on each card from them running cooler.

Also, at first I thought my cards werent working. If I would reboot, it would post and then hang on a black screen for like 1 minute. I always reset thinking it was froze. Instead I accidentally left it and it finally opened windows. I think the new roms must not feature fast boot.

Maybe we need like a -50Mv core volt, 1000mhz core, or maybe a 400mhz memory? I'm not up to speed on all of it though 

I have a few R9 nano can only work with th e-100mV memory undervolt BIOS. It will crash the computer if I use -150mV.

That means you need to use higher memory voltage BIOS, like the -100mV instead of -150 mV for the memory voltage

just got my Sapphire R9 Nano today...

before I begin the mod, just curious what's the best OC and undervolting settings at stock before modding?

I want to set that as baseline to compare performance before modding.

Thanks!

I have a question...

I run my Nano's at -96mv In afterburner with a -25% Power Limit. (55.3MH for the pair) Whole rig with i7-3770k (330Watts from the wall)

Core and Mem @ 1020/500

However....

When I Flash the cards to 800/300... -100mv

I cant over clock the core to 1000 without it crashing....

Not sure what else I could try?

also don´t know then...
except connecting a real display for one time and then set the display driver.

My display is already in the mobile mode, I cannot find the monitor in the device manager, what should I do?

Open Device Manager
Expand the "Monitors" list, right-click on the "Plug and Play Monitor" (or whatever here is listed) and then select "Update Driver Software"
Click "Browse my computer for driver software"
Click the "Let me pick from a list of device drivers on my computer"
Unmark "show compatible hardware"
at standard display drivers (left, 1st position) select a driver with the desired resolution (right)
thats all.

How do you do that, in which option?

Had the same problem on my remote RIG using Windows 7 and Teamviewer.
After unmarking "show compatible hardware" I´d selected a standard VGA display driver (1280x1024) manually, since then I get this resolution although no TFT is connected to the card.

No i don't

I have a few, but for my nano rigs i would need HDMI dummy plugs, and i find them to expensive to buy 20 of those just to have a larger screen :p

Greetings

Do you use the dummy plug for all your rigs?

Use a dummy plug :-)

I use 6 R9 nano, not attaching to the monitor. The dispplay will come "mobile display", the resolution is just 640*480, how can we make it display normally?
