Title: mod bios rx 480 nitro + 8go (samsung) Post by: matmator on December 31, 2016, 11:28:24 AM 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?

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, Title: Re: mod bios rx 480 nitro + 8go (samsung) Post by: ol92 on December 31, 2016, 01:52:28 PM Hello Hello,I moded my bios of my rx 480 reference.

When you overclock to >2000, you probably go to an other stepping: you need to copy the timing to other frequency steps above 2000 Title: Re: mod bios rx 480 nitro + 8go (samsung) Post by: doktor83 on December 31, 2016, 02:03:04 PM ...and not every card is the same...

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 may be wrong of course Title: Re: mod bios rx 480 nitro + 8go (samsung) Post by: matmator on December 31, 2016, 03:53:24 PM The overclock of the memory is blocked on I understand well?
How can I fix this problem? |
