guys can you tell me about hashrate of r9 380?
you can get max 175 Sol/s on v11
that sounds way too low. perhaps 275?
No its not. Its a 380 not a 390.
380 = R9 285
Its similar to the R9 280 and 7950 but The 285 and 380 are GCN1.2 vs GCN1.0 and it has a 256 Bit memory bus vs 384 Bit. Shader wise it has the same 1792 shaders but a newer architecture. Fiji (Fury Cards) use the same 1.2 architecture.
R7 260 Bonaire and R9 290/390 Hawaii use GCN 1.1.
Memory speed and timings seem to impact performance quite a bit. I had a 7970 with Hynix MFR memory. it did +- 200 with timing mod it went up to 235 sol/s stock memory clocks core 1100. Memory OC on stock timings got it up to 210.
im getting ~260 on a msi 7950 that takes oc to the max thats why i'm so surprised
