Mattthev you know the answer to this? Although not able to tweak. Stuck in hospital
2000+ is enough but yeah copy even to 1750. Depend what memory clocks you will use. All of my Samsung has at least 2000 (low quality) and better with 2100MHz with Uber-mix timings.

With that strap and mem @ 2000 I get 28.1 That is more than the modden 470x 8gb with Samsung memory (27.7) @2150 mem clock
Wait what? How can you have more hashrates with micron than with Samsung Cheesy Use Uber-mix!

I van only find uber mix for 480

Copy from 1500 up?

from 1875 is fine 

saludos

25.3 with those straps and mem clock 1800. That's a bit less than straps 1500 with mem clock on 1800.

Not sure if there memory (which comes default at 1750) will go to 2000.

It can be better, most micron can have 27MH/s and more. I've seen Micron doing 29.6MH/s, but that was only the 1 card Cheesy

At what wattage is the question. Now 25.8 <> 26 with 1250 core 1800 memory and -18 undervolt going between 110 and 116 watts
You can undervolt it like 980mV and less I would say with no problems. 1800MHz on clocks is pretty low, push it more.

Will undervolt tomorrow some more. Mem clock on 1850 -24 gives  me 26.7 now. Around 110 watts

Who has a decent overview of the memory strap settings of this card + some overlock specs.

getting 25Mh/s currently but want to see if it's possible to bump it with another 2-4

I think that's the maximum from a Micron memory but I am not an expert. That is a good amount if you are talking about Ethereum as even Rx 480 from Sapphire do not do that much out with stock settings, but again I maybe wrong, I have no experience in mining, only what I have heard from my friends.

Yeah it's out of stock with memory strap 1500 settings.sure there is more in that card

All of this is completely irrelevant since this is the BITCOIN section.  Move this thread to the altcoin section.
