Maybe some day I'll find a 570/580 card with 2250 ram... but today is not the day. I've noticed the mfg. only put 2000 ram in all the 4gb cards, they save it all for the 8gb cards it seems??

I think none uses 2250 yet...RX570s and 4GB RX580s use 1750, and RX580/8GB use 2000

8GB cards with Hynix go to 2250.

For example this Sapphire Nitro+ Limited Edition RX580-8GB has 2250 Hynix:

No, they have STRAPS for 2250, doesn't mean chips inside are 2250 rated...my RX560 Gigabyte cards have 2250 straps too,
card works at 1750, and its already factory OC-ed because chips on board are 1500MHz ones

Even link you posted clearly states "Memory Clock: 2000 MHz"

Yeah I've got some powercolor rx560's with 2250 hynix, 4 out of 7 cards will actually run at 2250, 2 run at 2000 and 1 on the stock bios at 1750 @ 84C. These are horrific cards I had to get a b250 board just to run them and it's not happy... the console is tottaly scrambled with pcie errors.

In any case who cares what the card is rated for, if it runs at 2250 without HW errors you're good to go. If it's got hynix with 2250 straps chances are you'll be able to run it at that especially with core underclock and core/mem undervolt.

As for the link I posted the clock is at 2000 because of the Samsung option, you can set the VRM to run the mem at 2250 if you have Hynix ram.

You can set Samsung to run at 2250 too...often easier than Hynix...I have EXACTLY the same Gigabyte RX560, some with Hynix and some with micron memory...micron has
straps only up to 2000 and happily mining at 2230MHz, while Hynix has 2250 straps and barely reaches 2050 MHz with default straps, and about 1950 with modified

2250 straps are there just for convenience, but what determines how high they'll clock is R0C, R2C or R4C mark on chips, meaning 1500, 1750 and 2000 rating

(and, of course, coolong solution, plus silicon lottery luck)
