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.

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.

everyone says updating bios is easy

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

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

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)

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

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.

I use RX 480 and got only 24 Mh/s

Is this normal?

Do you modify bios or do anything else? Overclock and others.

You need to modify the bios to get 27-30mhs.. there are guides on this forum and on google to mod the memory strap timing based on your memory type. Worth it and easy enough imo

Truthchanter for best hash/watt you suggest rx470 or rx480? What Brand is better? thanks!

Whatever is cheapest in my opinion, I get best hashrate with samsung mem. Sometimes its random whether you get samsung or not but there seem to be some models that certainly have samsung

memory samsung I use strap 1625 for rx 470 8gb

sorry to say you pal but elpida is way better than samsung at the moment on rx 4xx series

130w from wall  -100mv  1230 core 2100 mhz mem 30.6mhs

It depends Smiley

Hynix 4G, core 1135, mem 2100, 30.5Mh, yes that's -100 on the core  Wink

With custom handwritten timings, right?

I believe I am using 1500 on my msi 470 oc 4gb. hynix memory.

I also have one that is micron memory?  I thought they only made flash controllers?


Anway @ 1500 memstrap copied downward I cannot do above 1850 mhz or i risk freezing.
-100mv on gpu.  Running 6 gpu quite cool and well in a closed server case

What has hash rates do you get? Do you know wattage?

MSI RX470 (Samsung) IS BEST PROFIT  for gpu mining


  if you want to build a rig,
  have a limited money,
  care about money too much,
  and have to build your rig slowly,
  
  and if you have time for buying second hand GPU's on internet,

  
  +send a message to the seller and ask about to 'installing gpu-z program, and saying about the RAM mark, (don't say to searching about samsung mark cause if it samsung, seller understand that you have to buy his/r gpu, and  s/he will not make a good discount,  )
  +try to make a good deal for buying MSI RX470 (Samsung)

    
   buy a 500 or 750 watt psu ( select a good one) and build your rig, if your gpu number more than 3, buy another PSU, total 500+500 watt is enough, but 750+500 watt is more safe,


     RX470 (Samsung) IS BEST PROFIT 29.2 MH/s


note: my english is bad, i m trying to improve it... i hope it can useful for new miners,



hi otto 29 Mh on Eth?

For the elpidas, what strap timing are you using? 1500 or 1625? and I'm assuming 1500 for hynix?

I'm using 1625 for all my Hynix
