Have you managed to find a good value for RAS to go with the low RCD?

OK... I'm revealing my secrets.

Here are the formulas straight from wikipedia, not hard to find.

If you check ras, rcd, wr, rp, rc you can clearly see the formulas were used.
These values are not hocus pocus. They are calculated according to specific rules.

So if you change ras, you should change rc too and vica-versa

Ah thanks, that's actually what I was looking for.
My days of tweaking DDR timings are several years back... Fun to experiment with HBM actually!

One important thing though: observe the hashrate on the pool. Whilst miner hashrate might look higher, tight timings will decrease effective hashrate if your GPUs can't cope. TRM will show you that figure on the column most to the right. Have a look, you might be surprised.
