I'm stuck at 778H/s too. my mem is not stable over 2010... that's why I use 1375 strap.
You might use higher memory strap to get more stable mining of the Monero. If it is too high, it is not so stable.

LOL, system came out of hibernation and my secondary card was dead so I was like "Great" I have an excuse to upgrade to a decent miner (I sold all my dedicated gpu's 6 months ago) but on reboot it came back. LOL first time I was ever happy a card died and it really didn't!

OK, so those previous settings gave 800h/s but also produced invalid shares.
after some testing, I'm now at stable 775h/s which will have to do for now, as time testing is time not mining
CPU 1175@900mv
VRM 2060@990mv
Memstrap from 1500 copied over all the way to 2000
This now uses less energy than the default settings. The cards stay so cool the fans are now cutting out to 0rpm
GPU temp ~55°C

Tried a different approach: lower mem clock but with strap from 1375 mem clock. Reached 800h/s cc 1200 / mc 2025.
Not stable yet.
Not stable yet.
that's with the 470 OC, right?
Impressive. My RX 480 (1x sapphire reference, 2x sapphire dual-x OC) all deliver 630H/s stock.
The dual-x I got to ~690H/s with cc 1400@1200mv, mc 2100@1000mv
Do you somehow match up the claymore miner -cclock and -mclock settings or what do you mean with "strap from 1375 mem clock"?
I have the sapphire reference. I modded the bios with polaris bios editor-> core clock, mem clock and mem timings (the straps). Most of people use the 1500 mhz strap and copy it to higher mem clock straps. I found that for my card 1375 memory strap is best. it's stable at mclock 2010 => 780h/s.
with nitro cards you should be able to go higher , the mem is better( although the latest nitro 4GB comes with elpida memory instead of samsung and is not supported yet by polaris editor).
for undervolting you have to use TRixx or wattman or other. I run at core voltage 825 mV and mem controler 981mV. you should go way ver 800H/s. I'm looking forward to see your results.

Edit: just noticed you have Rx 480 then better see there: https://bitcointalksearch.org/topic/update-rx480-ref-31mh-custom-rom-vddc-offset-custom-timing-1584617
thanks man! Now I'm getting somewhere
tuned everything back to stock settings, fetched the bios from the dual-x 480 and copied over the 1500mhz mem straps to the higher clocks as you suggested. one reboot later, the flashed card does 807h/s@2000mhz memclock as opposed to 630h/s stock @2000mhz memclock...
I will toy around a bit more with this

Hi guys. i have found this gpu server. is it worth to mine with it? 
how we can how much H/s each CUDA core generate?

Those are specialized GPU, not the GPU used in mining-farm.
You need to test all of them but I doubt that they are cost effective.
You have the same on Amazon server, it's not new.

Hi there,
my sapphire rx 470 OC 4gb (ref) mines stable at 759h/s with modded bios (1500 timings and more) cc 1150 / 950mV - mc 2090 / 981mV
did not play with -h for now.

Impressive, whats the power performance compared to 480 and ndivia?
GPU-Z shows ~85W and I have 185W at the wall for the entire system (iddles at 80). As a comparison, mining ETH it uses 205-210W.
I think that beats nvidia. nice.
It was stable over night, still running, but i'm about to try over settings.

where do u find these modded bios?
You can find some in some threads in this forum (sorry don't have kept link).
But the one I use now, I made it by myself.
All you need is polaris bios editor and ATI Flash.
But carefull my first flash resulted in a bricked card. Fortunately had an old quattro in second PCIe to use to unbrick.

Hello Gingerale,
two questions
1) what works better ? Radeons, or Nvidea's ? R390 seems really cheaper then Titan (x).
2) How works Titan (6GB) vs. Titan x (12GB)? surely, the Titan has less cores then the Titan X .
I'm looking for a std board with min. 4 Pci-e slots. Found one with a Xeon 12 core.
laters ?

1. Radeon's get higher hashrate. Nvidias are more efficient (less electricity).
2. No idea re: titan. The miner software was written on Maxwell architecture. I think titan is the previous generation.
Titan X is Maxwell, original Titan I think was next older generation (Kepler?), Titan X Pascal is ... Pascal!
No Titan model is a good hash/$ choice though if you already have the card no reason to not try to use it.
They're way too much about "bragging rights" and you pay a major premium for that.
