It should be the Elpida. After that the miner crashed, couldnt close the claymore miner window and when i wanted to restart system it hanged at the point where it should boot up, wouldnt reboot. Switched the psu power button off and on and then it started fine no problems at all.

Did you get a OpenGL call in the log files of claymore? The over clock might be to hard on that card.
Also when a gpu crashes like that it could lock up the system hard reset only way to get it back

470 4gb Nitro with elpida after edit in hex 28.5mhs.
1100/2000 -100mV

470 4gb Nitro with elpida after edit in hex 28.5mhs.
1100/2000 -100mV

That is very fast. So there is little incentive to buy the 480x any more. That will not be more than 20% faster.

yes 470 4Gb nitro is great card for mining.

How did you flash it exactly?
You sure you have 4gb sapphire nitro with elpida memory?
Try switching the bios switch on the card and then boot

problem solved

in command prompt run "atiflash -f -p 0 xxx.rom"

first time i was running gui

Most probably your graphics card is unable to work with that under-voltage. I'd suggest increasing it a bit and try out some less modification. Set it somewhat like 900mV.

If that doesn't work, try lowering your Memory Clock as well.

and strange, I have checked the RX 480 and the RX 470 nitro both 8GB, and all memories are samsung

I flash the BIOS off my SAPPHIRE NITRO+ RADEON RX 470 8G and set manual with WattTool -13% Power so i get 163 mh/s by 800Watt...

Stable around 90 hours before last windows update reboot

Would you mind sharing the bios?

When I got home today my rig was off. Tried to power back on and smoke came out of one of my MSI 470 4GB. Had a modded bios but didnt touch the voltage. Been running for about a month.

Prolly shouldn't of tried to power again, and same gpu gave a puff of smoke right near the front of the gpu.

Anyway to get a gpu to post to switch the bios back for an RMA? Open to suggestions. GPU was being powered by a server psu and breakout board.

if spark and smoke starts to come out of the GC .. there is basically no way for them to powered it up for testing to acknowledge that you have used a custom bios. Just send it in for warranty.

Can they tell its a modded bios though? Will they still honor it?

My fault didn't read your whole message.

[fr4nkthetank]

damn that sucks.  you should undervolt your cards though, if you use afterburner or something like that, -75mv should be good, -100 should work too.

There is no counter on the bios flashing so if you can't flash the card back because it is fried they shouldn't be able to read the bios under most normal circumstances.

I had this happen on a Sapphire R9 280X Dual-X. It turned out to be a VRM and basically messed up the entire PCB. It was actually possible to start and run it for a few seconds. I got a few of the MSI 470, wonder why yours blew. Really strange for a card of this low wattage to blow a VRM. The 7970/280 usually had issues with VRMs blowing up because they were pulling close to 300Watts mining Scrypt.

If you were only mining ETH it shouldn't of used any more than 150Watts. If possible can you check and see which area of the PCB blew? Wondering if its the memory phases or the core phases.

Greetings to all fellow miners,
 
I've been running my rig steady for about two weeks and everything seems to work fine.

What bothers me is that today i felt a strange smell coming somewhere from the motherboard/psu. I cannot describe it as a burning smell, something more like the smell from new hardware being burnt in (if i can say it like that)

The rig is still working fine but i am not sure will it work in the future.

I'll put a screenshot here where you can see the power consumption and clocks.

The rig consist of 1 x ref Sapphire 480 8GB (flashed bios with low power consumption.rom), 2x rx 470 MSI 8GB with and 3x Rx 470 Sapphire Strix also 8GB. The 470's all are bios edited with 1500 and up strap copying, undervoltet with STRIX to -120mV, and clocks set to 1.100 and 1.750 memory clock for MSI (stock is 1.650) and 2000 (stock) for Sapphire.  Mobo is AsRock BTC pro, PSU is Corsair RM 1000i. Every card is connected to the mobo with power risers.  

As i said it works steady for two weeks, and i am getting around 160 MHS, with power usage from the wattmeter around 830-860W, and Corsair Link 900-920W.

I'll kindly ask some more experienced miners to take a look at the screenshot and check if everything is ok or should i change something.

Thanks

If your parts are new then its normal. Probably some flux being burnt off. If something actually burn your rig would shut off or at least that GPU would crash.
