Nice - Used the one offset voltage mod + your timings (your timings are indeed far better than any other ones when I tested them all - Cheers) at the 500mhz strap and yea, that's the only strap that matters anymore so memory timing is really the only way to get memory speed bosts on these cards. My Nitro doesn't overclock that well so I'm just at -1 offset core voltage @ 1075mhz... 1100mhz needs 1.275v minimum which is just a bit much for these power hogs considering I want it to last a while.

Not a bad buy for $85 including tax off Ebay.

01 00 1C 34 12 A0 22 8A 00 10 63 60 44 00 00 00 00 AD 2A 38 0C 73 28 22 0D 08 07 0C 0C 1E 01 10 0A 00 10 42
50 C3 00 00 08 21 34 16 E0 24 AA 00 14 63 6C 44 40 01 00 00 AD 2A 38 0C 73 29 2A 0F 08 08 0E 0E 35 06 15 0D 00 10 42 08

so yeah, just change the stock values with mine custom ones and you are good to go

the 500 and 600mhz straps use the same timings as you noted, HBM clocks are klocked on fiji, so 500mhz is the only one we can use.

let me know if you need further help, these cards are still amazing
Have you tried downvolting the memory to see if it reacts better to tighter timings? Isn't spec for HBM1 memory 1.25v?

Setting the memory voltage to 1.25 and it still passes FireStrike Ultra Stress Test with your modded timings. I tried 1.20v just to see and it was showing sporadic artifacts on the desktop. Right now I'm using your timings at 1.275v on the memory.

(on my card)i loose some points if i downvolt to 1.287v, i saw no increase past 1.3v.

So as far as I can gather, no HBM memory frequency increases are allowed anymore yes with new drivers? Even if bios sets 650Mhz, driver will overwrite to 500Mhz as far as what I'm reading in here.

Have a pair of these cards that will do 1365 with ease at -50, but memory is holding me back in benchmarks.
