Sapphire RX 550 2Gb Best ROI ~ 450 H/s cryptonight

[Truthchanter]

For modding the bios for memory strap timings, what is recommended? I used to use custom memory strap timings for eth for 470s and 480s but never looked into memory strap timings for cryptonight

I just use the PBE one click mod, it does the job great, unable to squeeze more with custom timings.
I saw an old thread that claimed Gigabyte rx560 4gb can get more with custom timings, but the guy who wrote it wanted a ridiculous amount of money for it.

Since its cryptonight, it was probably Matthew, not me  , but "ridiculous amount" is too broad statement.

If you have 1000+ of the same cards, your ROI for BIOS would be 1 day or less even with minimal increase in

hash rate, so don't take your own case as general rule

You didn't write for what type (manufacturer) of memory is this strap, so I suggest people don't try it
before we find out. Nothing too bad can happen, but less experienced people could have problems to recover
their cards to working condition

Is this tuning for algo Cryptonight Legacy or Cryptonight V7?
