MSI RX470 (Samsung) IS BEST PROFIT for gpu mining 29.2 MH/s

[Truthchanter]

Samsung is not the best, I have 3 Elpida 470s dual mining at 30-31.

Do they consume extra power for that? If so the efficiency isn't worth it

I don't know how he got close to 30-31 with elpida unless you customized his own memory strap

EDIT: I PM'd him. It seems he just has good elpida chips.. It seems not all elpida are the same as mine aren't stable past 1975 or 2000.

Regarding your 470s with elpida hashing at 30-31, which mem strap did you use? Or if you used a custom mem strap, did you base it off one of the original like 1500, 1625, or 1750? and what is your mem clock?

1500. all 6 of my visiontek 470s hit 2080 mem.

Actually a 30Mhash ROM for 470 Elpida has been published on this forum too

Setting 2000-2100Mhz for any 4GB is not good because after 12hours or so you will get like 5% hardware errors per GPU.

Only way to fix those is to do a hard power shutdown and reset.

Why do you think hardware errors are limited to 4gb cards when mem is clocked from 2000+? If I remember correctly I got hardware errors on both 4gb and 8gb cards but just ignore them (as ignoring them seems to be the consensus)

Anyone has a 8gb micron one? Its currently steady hashing at 25.5 but i wonder if i can get it to hash out a little more

everyone says updating bios is easy

Shows it's not. Do they just flash someone else' bios or what?

Actually I'm running my samsung memory cards at 2150 without any memory error (not 0, but almost none) and usually they need a reboot every month.

I think it depends if they win the silicon lottery or not, as almost always.
