Title: 290 to 390 bios mod for mining Post by: Charloz24 on November 30, 2016, 11:21:51 PM Anyone did it? Does it help for mining ZEC or ETH?

Here is the thread with instructions https://forum.ethereum.org/discussion/6866/got-any-290-x-reference-cards-read/p1 Title: Re: 290 to 390 bios mod for mining Post by: Charloz24 on December 01, 2016, 12:06:15 PM Should not result in any improvement, A 390 is just a 290 bundled with 8GB of RAM. Do 390 mine ZEC near 300 sols/s? Because the max I have with 290 right now is 245 sols/s.

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

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. |
