Thank you guys, I decided to give it a shot... and it seems that with the "lifting" to the timings and a boost to the mem freq the results are much better than the stock bios even for Elpida model.
I'm getting about 390h/s @1875MHz but I'm testing the stability since already @1900 I'm getting BSODs in a bunch of seconds.
Don't you know if it is recommended to increase the mem voltage to try to work @2000MHz? Because at stock voltage (1000mV) I think it will be hard for this card to go beyond 1875MHz.
I would also consider to decrease a bit the GPU frequency and voltage not to stress the card but I don't know if it will worth.
I didn't play with cryptonight too much lately...but I think memory frequency is less important than core frequency for this algo...or, at least,
much more important than for ethash
I don't want to have headache playing with core and voltage. The card is almost cold under CryptoNight so I think I'll let it so.
Thank you.
