Should not result in any improvement, A 390 is just a 290 bundled with 8GB of RAM.

 Not quite - the ram was also faster (1500 vs 1250 clock).
 I think the R9 390 also implimented the "boost clock" stuff in BIOS but not sure on that.

 I'm not sure if the R9 390 added PCI-E 3.0 compatability.

Try 1100/1450 you should get 280Sol/s

Thanks I will try it, but Are you able to undervolt -100 mv with these settings?

No with a undervolt it should crash with a OC like that.

Do 390 mine ZEC near 300 sols/s? Because the max I have with 290 right now is 245 sols/s.

It made a different for ETH. But was more related to power consumption rather than speed. Bios was similar to Stilt actually.

Here is the thread with instructions

Anyone did it? Does it help for mining ZEC or ETH?

TIA
