Been testing Lexa RX550's (2gb elipida) with this tool. (To get them running with amdmemtweak linux cli version you need to add
(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.
win cli version how to add support for 0x699f Lexa [Radeon RX550? the other question, 1930 core? is it 1130? I do not think the card can do with 1930 core?
