The weird one is the first one of a new set of straps. Some cards support more than one memory type and have multiple sets. 40 9C 00 is for the 400MHz strap and is only for when the card is completely idle, so it's the first entry for the 2nd set.

40 9C 00 02 is the 0-400Mhz Strap / Ram ID 2 (Hynix MJR)

P.S. Hynix also have a E8 6E 03/2250Mhz Strap. Good for High Mem OC

Probably by setting the VID to 950mv you are providing more power to the memory voltage controller ?

Isn`t it correct to increase only the memory voltage rather than setting 950mv VID ?

RX 480 memory voltage is tied with core voltage, i got better score and low EDC errors at 2200mhz vram clock than increasing vram voltage.

Here's my experiment :
Clock 1480mhz - 2200

vid 1200mv - over hundred thousand EDC errors and slight artifact at firestrike.

vid 1200mv - 1100mv memory volt - still same EDC errors but no artifact

vid 950 +offset 32 - stock mem volt - no artifact and EDC error lowered to 5xxx

Send me your bios, i'll mod it with hex editor for you.

Thank you for the response, indeed what i was expecting.
Well, my memory doesn`t run at 2100 even on stock timings na core voltages, so it`s not stable. It`s fine without EDC errors around 2070mhz.

I`ve attached my bios and will be happy to give it a test after you modify it smile.gif Huge thanks

I saw some Rx 580 bios posted in techpowerup do you think they would work on Rx 480?

I doubt it, RX 580 bios are a bit different and most AIB models carry 8+6pin connectors, while 480 are limited to

As I see it, there's little point in the change. RX 580s are tuned to consume more power to get higher clocks but there is no performance gain at the same clocks, and I doubt 480 could go higher as they aren't power limited.

MSI Gaming X 4G and 8G seem to have identical specs for 480 and 580 (gpu and memory, and power connector). Flashing 580 might give us the intermediate memory state so system doesn't boost to 7/8gbps when u open YouTube..
