Title: Low Hashrate Problem Post by: MinerC1 on January 17, 2018, 05:29:55 AM I built a new rig.
Gigabyte Z270p-D3 Mobo Currently had 4x MSI RX 580 Armor 8G OC GPU's installed. Powered Risers I flashed and tweaked each GPU individually and got them each to a stable 30 MH/s. But once I powered the system with all 4 GPU's installed my hashrate dropped to around 19 MH/s each. Using the blockchain AMD drivers, mining with claymore. Modded Bios (only edited the 2000 strap) Core Voltage 950 Core Clock 1135 Memory Clock 2200 MSI Afterburner also will read all 0's for the cards when multiple are connected but works fine when only one is connected. Im stumped here, can anyone help me out?

Title: Re: Low Hashrate Problem Post by: 0xcosmos on January 17, 2018, 06:14:02 PM did you enable 4g decoding in the bios?
did you change the pcie lane speed to gen1? did you increased the virtual mem to 16gb?

Yes all of the above has been done. Title: Re: Low Hashrate Problem Post by: patofet on January 19, 2018, 07:43:43 AM I have like 24 RX 580 8Gb, and each card give me diferent MH/s like, minimum 18MH/s and maximum 28MH/s in the same conditions and the same that your conditions. I'll stay tuned here ;D
