2 GB or 4 GB DDR5 for cscrypt Mining like R9 270 X

[Jarvis2.4]

Dear Friends,
Which will have more Mining Rate at same Clock , The 2 GB Version or 4 GB version.
I am planning for 3 No. 270 X but confused in terms of memory. I think the cscrypt is more dependent on memory. Is it true.
Need your suggestion.

Thank you

It doesn't really matter for scrypt.
So get the cheaper one i.e the 270x.

I would recommend 280X with the more or less same power consumption you will get around 700kHs per 280X

With my experience I couldn't find much difference between 1GB or 2GB hopefully you may not find much difference with 2GB or 4GB

Go for the cheaper 2GB one , hash rates will be same.

Thanks for your suggision . In case I am Not looking at efficiency and Power consumption. Which Cards will give more hashrate in terms of Card price? I want to make cheapest possible side rig with non efficient Cards . I can accommodate 2 x16 and one 1X card slot.

i would suggest you go for the 280x - Asus preferably. it'll give the best price to hash ratio.
But if you re looking for scrypt miners i would suggest you go for gridseed miners

Here's a google sheet made around litecoin mining. So may not be completely useful. Forgot who has posted this first :-)

I think they 've made a mistake with the gridseed. doesn't give 330Kh/s?

Yes. infact I get 355KH/s. They probably meant the old USB dual miner 70KH/s. The sheet is a tad old.
