Been testing Lexa RX550's (2gb elipida) with this tool. (To get them running with amdmemtweak linux cli version you need to add

Code:

(dev->device_id == 0x699f) || // Lexa [Radeon RX550]

to IsRelevantDeviceID.

Starting hashrate was approx 529H/S with TRM 1930 core, 1750 mem.

I lowered RFC to 82 (crashes at 80), and messed around with raising REF. Running at RFC 82 REF 50 gives around 545H/S.. which is a nice increase.

Cards also seemed stable at REF 100, and this got around 549H/S. How high can REF go? Well turns out no higher than 150 with my cards at least.

Seems like there is even more room for improvement with these cards... I will continue to experiment. I noticed someone selling a BIOS mod that claims 650H/S on these cards, so that seems like a nice target (if it really exists). Am I correct in saying that REF can't be changed with a BIOS mod? so this 650H/S bios mod (if real) must have gotten the increase without using REF?

Thanks for the tool, hopefully will report back with better hashrate increases for these cards.

I have some rx550 cards. I have baffin 8cu cards. They are soo efficient
I have managed to get up to 560hs with 1930 memory clock.
Maybe some of the new parameters in new cli version will push it higher.
