You can find sony87' original rom here: https://forum.ethereum.org/discussion/10299/470-nitro-4-gb-elpida-memory

Two things:
First 470's seem to have a hardlock on 2100 Mhz RAM -my Nitro cards behave like they could blast through that limit with ease.
Does anyone know how to remove the 2100 Mhz limit?

Second> Cards can push both to 31800 Mh/s with curent bios and higher tweaks, bit unstable tho, but I dont like the power draw on them -unless you have free electricity.

If I could remove the 2100 Mhz hard limit on RAM than I could get even higher rate.
Till then, I'm undervolting/underclocking for better rate with lowest power draw

Get low:

Next step: more tweaks less draw

Edit> last two cards are 470s

how much you undervolt your vga till get 71watt powerdraw? it's seem imposible, i have tried it more but if i undervolt the hashrate will be down too, currently my setting 28mhs with 114watt powerdraw.

can you share how to get 71watt without making the hashrate down?

@sony87 mod download link is down
Could someone please upload it somewhere else ?

That was such a great mod.

Anyone got any ideas why windows locks up when I start claymore. It gets to loading dag then locks up.
All cards are over locked. Most of the time it's the card with active video for teamviewer

Cards were at 1130/auto core 1945/955 mem
Moved them too 1130/auto core 2000/1000 mem

To much of an overclock?
Didn't move power.. maybe Up the watts?

If cards mine rock stable at higher frequencies and You have problem only with Claymore starting, try -lidag option:

"-lidag low intensity mode for DAG generation, it can help with OC or weak PSU. Supported values are 0, 1, 2, 3, more value means lower intensity.
You can also specify values for every card, for example "-lidag 1,0,3". Default value is "0" (no low intensity for DAG generation)."

i did try this. it worked once so i thought i was good. till a gpu locked up in opencl call.
i was pushing the 470s a little to hard 1945 is the sweet spot.
2000 mem only gives 1 more mhs but i cannot keep it stable for more than a 12 hours

You are probably generating crazy amount of memory errors. Some cards can do 2000MHz with low mem errors rate, some don't. As stated before -lidag can also help.

Now the money is free, and so the people will be

yeah I find some 470s can have reported core temp quite low, but vrms will be pretty hot. for example I had 55c core, so i put the fan pretty low, but vrms were almost 100c...this is due to bad cooling design IMO. wolf made a great post about something related to this. I actually ordered 1 xfx 480 4g today just to check it out, looks like the vrms and memory is actually cooled.

I know ,I'm not used to it yet but you still have to watch it more then anything else

. it can heat up fast.

guys give me the exact link to download the rom for 470 rx nitro 8gb?
because I have already ruined a bios video card, and I would not want to spoil the last one left.

After I show you what I did to change mod

You can fix it by flashing stock back to it. Even if I wanted to, I CAN'T give you a VBIOS guaranteed to work with it unless I had the stock one.

I tried it again flashing the original ROM, but if I put only the GPU remains black screen

Does it hash as a secondary GPU?

no no, the gpu rx 470 nitro, with 2 fans, has 2 bios, you know you have a small lever,
1 of these bios does not go, the screen remains black,

Here's what you do. Flip it to the working one. Boot Windows. WHILE RUNNING, flip the switch to the broken VBIOS. Flash stock to it. All fixed.

I see 95-100c on my ref 470 4gb VRM's, it's quite nominal range for that card model.

VRM'S are rated pretty high, IMO if you see 80-85c there is absolutely nothing to worry about.

try at default setting first if it works then your over clock setting are not adjusted right with each other .

I have noticed that on some of my machines the card that is the primary display adapter, that you connect to a monitor etc, needs to be set to a slightly lower overclock/higher voltage than the rest for better stability. This card has to run additional system threads and can cause freezes/lockups.
Your clocks are pretty high already, I would recommend not getting greedy and sticking to 1130/1945. Raising them further will hardly net you any noticeable gains while pushing up power usage as well as causing instability. Happy Mining.

Okay thanks to both of you
I'll bring them all back down to 1130/1945/955.

Great info thanks guys !

What the best solution to clock them quickly with theses specs ? (kind of newb with all the Bios mod vs Wattman)

Thanks

Memory speed capability mostly determined not by gpu itself but the memory chips installed and its cooling. Asus afaik has no mem cooling so this combination - slow hynix plus bad design yields low stable mem speeds. I run 1950mem with 1375 strap on sapphire ref-like rx470 without mem errors in hwinfo64.

I was a bit skeptical, since I've worked with lots of servers before and the RAM would only get warm to the touch. However, I rely on data rather than my ego to determine what is correct, so I got out my IR thermometer and was surpised to find spots on the back of the card as hot as 98C. I bumped the fan to manual 60%, and that brought the hot spots down to the 80s. I then got out my infrared camera, and I could actually see the rectangular hot spots from the RAM on the other side of the board. The worst is above the GPU where the aluminum heatsink blocks any airflow over 3 of the DDR chips.
With a small rectangular piece of aluminum plate and a thermal pad I could probably make a thermal bridge from the RAM to the heatsink to cool them down...

See my post here: https://bitcointalksearch.org/topic/wich-is-better-rx-470-refference-or-custom-fan-1615394

Actually I remember seeing that when you posted it. But nobody actually gave any concrete info on the effect of DRAM cooling. Had I known that they can get over 95C without heatsinks, I would've paid more attention to that when buying a card. With the back of the board in the high 90's, the DRAM die likely was over 110C, or 25C over the maximum operating temperature for most Hynix RAM (85C).
https://www.skhynix.com/static/filedata/fileDownload.do?seq=267

Since power scales exponentially with voltage (close to V^2), if I can undervolt the memory a bit, I might be able to keep it cool enough to actually overclock it a bit more. I'm sure the Digi+ VRM can be controlled through I2C, but I don't want to dig up a data sheet or reverse engineer the register set in order to do it...

There is no software voltage control *on ref cards.*

The overclock is too much. You need to reduce to the stock to start with, then raise the frequency gradually.
