- I'm working on writing my own custom tools to work with and tune the GPUs myself. For example, a mostly-decoded set of timings from the stock Sapphire RX 5700 XT (reference) VBIOS for the Micron MT61K256M32 memory ICs (integrated circuits), for frequency ranges 1875Mhz - 1999Mhz, inclusive (or, as shown in Winshit, 937Mhz - 999Mhz, inclusive.) VBIOS P/N is 113-D1820501-101, and it can be found here (with SHA-1 hash 4ad5e0861ddf3b2381c1ce04a8d2799a5e247677): https://www.techpowerup.com/vgabios/212169/sapphire-rx5700xt-8192-190616
