Title: [WTS] Highly optimized bios for 4gb Samsung RX470/480 Post by: christiano88 on January 06, 2017, 12:02:41 PM The bios is completely custom made with custom timings, didn't use the common trick with the straps which only get you up to 10-15% more speed.
Confirmed cards that have 4gb Samsung memory: Sapphire Nitro+ RX470 and RX480. These also come sometimes with Hynix (especially 470s), so make sure to check before contacting me. Latest batch as far as I know comes only with Samsung. Mining speed: +25-30% more than stock on monero (up to 835h/s on RX470, up to 850h/s on RX480). Didn't test on 8gb Samsung memory, but it should be compatible (timings are similarly made between 4 and 8gb on stock bios). Still, I don't guarantee the same speeds. PM me only if properly interested, and only if you have 40 rigs or more, or the price might be a bit steep for you (fixed, one-time price for the bios file set at 0.9 BTC). This investment can be recovered in ~2 months with ~40 rigs, ~1 month with ~80 rigs, ~15 days with ~160 rigs, so on and so forth). As a bonus, any update I make to improve the bios will be given to the clients who purchased, free of charge. I will only send the bioses if at least 2 clients are in the final stage of acquisition (sent payment). Also the sale will be limited to 5 clients max to not affect the difficulty and make the ROI of this investment harder. I will post proof in a few hours.
