RX580 Sapphire Nitro+ 8GB Hynix at 1150 Mhz Core and 2150 Memory and Voltage -75mv - Trixx
RX580 Sapphire Pulse 8GB Hynix at 1150 Mhz Core and 2150 Memory and Voltage -75mv - Trixx

Maybe not all cards can be undervolted -75mv OR maybe more then -75mv

Strap copied to 2:1750, 2:2000, 2:2250:

Long time i tried bios mods and many other memory straps, this one is the only working flawless with 30 MHs.
Other straps got me lower MH on memory overclock or blackscreens and artefacts

@error5404 that custom strap is a beast worked for all my Hynix 580s , I donated $50 in BTC thanks

btw off topic a bit but i have a bunch of 480 xfx gtrs with samsung ram that i had to dowclock mem to 2000 due to instability, these use the typical 1725 or 1750 strap down to 2000 similar to the ref samsungs but unlike ref alot of these cards crash with higer mem clocks with thst strap. I heard theres a better custom strap for these any thoughts?
will tip if i get a solution

Custom samsung timings. Stable for most of my cards at 2100, 1/3rd have to downclock to 2080 or 2060

Thanks. I will try it too on my Asus RX 480 Strix OC. Could you advise at core clock and mV?
RIght now I am using 1750 to 2000 strap and works at 29MH with core clock 1170 at 930mv and 2080 mem at 940mV.

Thanks
