Regarding the RX570s, what is the max price you're willing to pay before the card becomes too expensive ? I have an option to buy some 570s Asus Expedition (it's one of the cheapest versions) for about $235 per card. Is it worth it or is it too much for a basic 570 ?
That card can do 27mh/s tops. Try To find the mini itx
BS.
My RX 570 Expedition oc's hash ETH at 28.5 while dual mining Sia at 453.5. All 14 of them.
What speeds and memory? Mine have elpida. 1850mhz Max clock without crashing
Elpida.
1100/2000 on all cards. A couple of them throw a handful of memory errors (as in single digits over several minutes - so irrelevant), the majority doesn't. I could spend more time and o/c every one of them separately but so far no need.
If you only copy the 1500 straps up your o/c will suffer. You need better timings. Ask mattthev for a strap, he sells them for very decent prices and helps you in the process. Very nice chap.
