Mind sharing the strap values that you used? Also if you incurred in EDC memory errors.

My hynix can't go over 1900mhz at stock timings without several memory errors (not artifacts).

700mv IMC + 2250Mhz 4GB ... Something is not right

Yeah, I dont think you can even go that low on the IMC. The speeds also seem suspicious because the hynix IC's are really 1500mhz rated, going to 1750 is already a 250mhz overclock, that is why 2250 would be a 50% overclock, should be a godlike bin (and with the 1750 strap too from what I get from the polaris bios editor screen).

Here it is
And yes imc at 700mv, i've tried with 1000mv 975mv 925mv all of them were never finish firestrike and got so many artifact + millions of memory erros. But 600mv and i got no screen at all after reboot. So i decide to stick with 700mv.

Actually 1625mhz and i also change TRP value to 197 or C5 in hex, TRC to 83 or 53, and CL to 21 or 15.

Have you tried any games? If you have Battlefield, running on Max uses ~3GB memory and if its stable then, this is good.

You seem very knowledgable as to what each hex value represent in actual timings. Where are the main timings located in the strap value? I will try your strap but I would like to know what value is t
Cas, ras, trcd, trw etc. Thanks in advance!

Those are timings that i need to change to achieve 2000+ mhz, and i dont want to mess with other timing since i dont think it's necessary

Assasins Creed Syndicate at very high settings it used almost 3.5gb vram, played it for 2 hours and no crash no artifact, so far so good.

.

How can we define RAS, TRC, TRRD, CAS values in strap timing?

Those are the ones which you changed, but, do you know what the others are? Like, which one is the Command Rate (CR)?
