mod bios rx 480 nitro + 8go (samsung)

[matmator]

Hello

I moded my bios of my rx 480 reference.

Copy of timmings 1750 to 2000. and mounted memory to 2250.

And I have 31+ mh.




I have a rx 480 nitro.

Of origin I have a hashrate of 24mh,

When I copy the timmings 1750 to 2000, I have 28mh.

But when I then mount the memory to 2250, I stay at 28mh.

Even at 2300mhz, my hasrate does not move much, it remains at 28 mh.

Max 28.4 mh

I do not understand .

Has anyone had this problem?

ive the same problem , nitro+ 4gb , if i go above 1950mhz at memory clock , the gpu is crashing , and im having problems with invalid shares , end overclock error problem at pools ,

also im curious how did you go above stable 2000mhz without having problems ??

im using 1120 clock , and 1850 mhz with 60w per card mining monero  at 720 h/s,

Hello,
When you overclock to >2000, you probably go to an other stepping: you need to copy the timing to other frequency steps above 2000

...and not every card is the same...

I have a rig with 6rx 480 (reference)

Bios mode like this: copy timmings 1750 to 2000

and that's all .

Then in wattman I configure like this:

Gpu clock: 1200mhz / 920mv
Gpu memory: 2250mhz / 950mv

And I get 31.2 per card, except one that I am has 2200 in memory.


But with the nitro ca changes nothing at all when I mounts the memory, it will say that my value does not validate. .....

I did not quite understand what you meant my friend

Usually amd timings are applied to a frequency range : the bios applied a set of timing for frequencies between x and x+250 for instance (I don't know the exact steps) and another for X+251 x+500 and so on.
When  you applied the 1750 timing to 2000, I suppose they are not applied for frequencies above 2001...
I may be wrong of course

The overclock of the memory is blocked on I understand well?

How can I fix this problem?
