Title: Advice&Help Needed Post by: lohi on January 12, 2018, 07:35:49 PM Good evening fellow alternates,
So the story goes like this Got Sapphire RX570 8GB Micron memory Stock was 24.5MHs Flashed Bios after flash got like 1MHs, started overdrive Playing with overdrive trying to get higher MHs, by disabling gpu except p7 and Mem except p2 Said to increase by 50 Mhz(running HWInfo) until i get memory errors then decrease by 25 until working properly. The "issue" is in the "tutorial" it says the cards work great around 1850 MHz at 900 mv The bigger issue is i am currently at Settings in Overdrive GPU: P7 1150 850 Memory 2050 900 showing 28.7 MHs without memory error in HWInfo or rejected shares, only after every 5 stats in claymore i get a single drop to 20MHs ad then it goes back to 28 How high CAN i go with mem timings?

I believe that this is not a problem with memory timings, but a lowered voltage of the GPU. 850mV is small, try at least 900mV.

Sorry for the late reply, but are you saying that the fact that i have/can to increase mem timings so high is that my gpu voltage is to low? Does that mean if i increase the voltage i can get the same hashrate with lower mem timings? |
