Heliox - just to update that I managed to get the -175mV working on the new batch of Nanos.

I have not got all 6 cards in a complete setup yet, but testing on 1 card is a success.
I will run it overnight before flashing the other cards.
I will report the kill-lo-watt meter readings tomorrow morning.

As of now, with -175mV rom:
-6mV,1040/300 = 30.3MHs at fans= fix 60%, temps 67-68c
and
stock -175mV,800/300 = 22.4MHs, temps 62-63c, auto fans

I am tempted to try the -200mV rom.

Is it normal that some rigs will have 150 roms and some 175 roms, mixed configs in your environment?

how do you guys mnaage to raise the core on the modded rom cards ? i have several -175 six card rigs and th seccnd i change to core from 800 to even 950 the box crashes

I was wondering why I was able to do it and many have commented that they cannot.

I think I know why.

My H81 is powered molex and my USB3 risers are also powered -- both powered.

with a kickass PSU like EVGA-G2 1300w or 1600w, cranking it up to maximum was a breeze.

has anyone tried to overvolt an unmodded nano to see how high it can be overclocked?

out of the gate; -100mV/1040/300 = gave me 32MHs then stabilized at 30MHs using CDM 4.5 !

It was impressive - then I decided to attempt the -175 mod because I need to reduce the power consumption.

at -175mV rom mod, -6mV/1040/300 = 30.5MHs at even lower wattage - fantastic!

I am getting the killawat meter to do a before and after - will post soon.

It is very normal. I have nano accepting the -200, 175, 150 and 125. That is depending on your luck.

I had no luck with Nanos I bought from Amazon - best was only the -150mV working, not the 175 and 200 mods
But this new batch seems to be ok - I was surprised to get it to 32MHs -100mV, 1040, 300 without the rom mod.
With the mod, I am getting 30MHs -150mV,1040,300 with lower watts and amps - which I need because electricity is expensive in my country.

My XFX Nano was from Amazon and it's working good with -175mV.

I've modded my sapphire 380 tonga bios. temps went from high 75-88c to 67c.

I haven't ran the kwmeter, but I'm guessing the 380 now pulls about 150-160 watt per card now at 20mh/s.

My main concern was heat being transferred into my apartment Tongue

EDIT: got the temps down to 53-68C on the 380....aah no more sweating balls.

That is very good result. My 390 can mine 27.5 MH/s with 160 W. So that is good achievement for the 380.

Small update (got a pm from someone with issues.)
For those with problems, this package "here" includes -106mV, -112mV, -118mV and -125mV memory clock.
Core clock is still 800 stock, memclock 300, core voltage -100.

If you still have problems with one of these roms, pump up your core voltage (+6mV), some cards just won't do -100mV with a monitor attached.

New Update

Details rom usage.
---------------
Ethereum tests:

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

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

Enjoy![/size]

What the highest hashrate you were able to get out of a nano?

I have 29-30MHs with -150 mod. -6mV/1040/300

A few more Nanos coming in today - so I will try again the elusive -175 and -200 mods - it could be batch issues - will let you know results. The -175 mods is really the one that I would like to have for these Nanos.

Btw, do you have the link for the 390 rom mod? Will it work on MSI-R9-390?

Sounds great

No mate, read my post a few pages back. Only for Sapphire 390 Nitro w/ Backplate.

Greetings!

The MSI R9-390 are also with back plates Grin

Using CDM v4.5, ethpool.org and for both rigs below, 0% invalids. Powered risers and molex. '

H81-BTC/Celeron1840/W81/8GB RAM/120GB SSD/EVGA1600/USB3 Powered risers.

MSI R9-390: -100mV, 1050mhz, 1125mhz, 30MHs per card, 5 x 390 = 150MHs, temps=75-76c

Sapphire Nano: -150mV rom mod, 1040mhz, 300mhz, 29-30MHs, 6 x Nano = 177.8MHs, temps=74-75c

Ill try plugging in the molex if you're getting that low of mV on 390s. I can go to about -75mv but if my miner dies or I close it the system crashes. Mine hash at 28 with stock core clocks. Your temps are way hotter than me though, I never go above 65C? This is in the top floor of a building that stays 85-95F. My cards are vertical. I'm using powered USB risers also, didn't mention that before. H81, i5, 8GB ram, SSD, ax1500i psu.

I've been having really bad luck with CDM 4.3-4.5, won't connect to servers or it crashes randomly. Rolled back to 4.1. Cry

@Eliovp, will that 390 rom work with a 390x sapphire Nitro? the silver not the gold?

I live in a tropical country near the equator, so 75c aint too bad. I have box fans running 24x7 on the rigs.

Using -150mV rom mod on Sapphire R9 Nano
Results: Clocks:800core/300mem, 657watts, 2.67Amps, 132.5 MHs, temps=59-61c, fans=19% (mining ETH mode, CDM 4.5)
Current system: Win8.1, Cat-16.5.3, ASrock H81-BTC, 1840 Celeron, 8GB RAM, 120Gb SSD, USB3 Powered Risers, EVGA1600

Notes:
1. Big saving$ on PSU - now can replace it with smaller PSU.
2. Cranking up to core clock to 1040mhz/300Mhz memclock, gets to about 176MHs but wattage and amps will increase too 1348w and 5.4amps. Temps will also rise to 76-77c and fans 49%

Next project 2nd attempt on -175mV rom mod.
It worked well on 1 x Nano (see my previous post)
When I got all 6 on same rom mod, I had issues bringing up safe mode to apply DDU. I may have given up too soon. Will try and get this going after I see how stable the -150mV rom mod runs after a few hours mining ETH only with latest CDM 4.5

UPDATE:
1. Looks like -200mV is not for me.... after flashing, power off, DDU etc.... installation of of Catalyst 15.12 or latest 16.x.x hung halfway at 12%. Rebooted cold or reset, blank screen.
2. well.... the -175mV rom did not go well too.... after reflashing, DDU, install of Catalyst latest drivers... Launching CDM goes silent after identifying the Nanos. Tried qtminer, also no luck.
3. Decided that -150mV is probably best mod for now until Heliox gives a few more ideas on how to fix issues above.

Citronick,

I have 3 or 4 cards that have been stable with the -200mV since i released it. the others gave up after a while as well tbh.
For now i have 3 cards that are running the -150mV as they kept failing after a while as well. All the others (90pcs) are running with the -175mV rom and are stable for over a month now. A few rigs even longer, 40+days non stop.

I can't explain why some seem to have so much issues with the "tough" roms as it all goes smoothly over here. Maybe it's because i have an early batch? Dunno..

What hashrate do you get with this rom?

Currently running @ 1220 core clock @ around 35-36Mh/s. 1260 gives me 39 but temperatures rise to 85degrees because it's getting hotter every day here.
