Hey folks
here are my results
Nitro+ rx 470 4gb:
before 750 H/s ; after 790 H/s = +40/50 H/s
power draw before 650w ; after 450w (500w) = -150w
-h 900 -dmem 1
rx 470 8gb mining edition (samsung)
hashrate 845 H/s
power draw 75w
-h 1800 -dmem 1

If i set set GPU_FORCE_64BIT_PTR=1 -dmem 1 -h 896 i have 502 h/s, if set GPU_FORCE_64BIT_PTR=0 -dmem 1 -h 512 I get a 530. That's the problem.
Setting -h as high as possible is good only for modern Polaris and Vega cards (don't know about Fiji) with blockchain drivers.For older cards (hawaii, tonga, etc) you should find the sweep spot. And it won't be the max value
If i set set GPU_FORCE_64BIT_PTR=1 -dmem 1 -h 896 i have 502 h/s, if set GPU_FORCE_64BIT_PTR=0 -dmem 1 -h 512 I get a 530. That's the problem.
The -h parameter for 270/270X/370 is 512 the best. You can check it by launchung without -dmem 1 option.-dmem 1 option is increase a little speed on these cards. But if -h parameter optimal without -dmem 1 option than it will be optimal with -dmem 1 option.
530-540 h/s is the maximum for these cards i think.
then its not the best 
It's the best available for everyone that can be found in internet. I think that it not the best too. But I can't find better... [/quote]
cause you are both stupid enough to disallow 64 bit gpu pointers
you should
setx GPU_FORCE_64BIT_PTR 1
[/quote]
Well you're one smart. Installation setx GPU_FORCE_64BIT_PTR=1 helps, That much I know. But it is impossible to achieve the maximum memory values with the parameters -h and-dmem
[/quote]
setx is used without equal (=) sign.
= is used with set command, e.g. set GPU_FORCE_64BIT_PTR=1
And what problems with -h and -dmem?

I'm able to get about 760-790 h/s with 10.2 on my cards. Mix of RX 570s/580s 4GB.
On a 580 8GB I have it gets slightly above 800 h/s but thats about the best I can get so far.
If anyone has gotten higher and have any tips let me know.
Thanks
On my RX 580 8Gb(hynix) 1380/2200 I can reach 840-850 h/s -h 1800 -dmem 1On a 580 8GB I have it gets slightly above 800 h/s but thats about the best I can get so far.
If anyone has gotten higher and have any tips let me know.
Thanks
There is some peoples have 1k+ h/s on 480... I don't know how.
with ubermix 3.1 straps and samsung mem
No, please do not try to use memory straps from SAMSUNG memory on HYNIX because you risk breaking your card.
And you must know that almost half of modified straps in the internet for hynix, elpida, micron are maked by modifying memory timings from other memory.
F.e. best memory timings for RX 580 8Gb with hynix that you can found in internet taken from 1750 micron memory strap of RX 480 8Gb without any changes.
what is the hashrate with the micron straps?
then its not the best

Why your miner see only 3072M of video memory on R9 270X 4Gb card?

The same situation with graphics cards r7 370

You asked for advice, I gave you advice. I see that you have little to no knowledge, and want to defend it instead of wanting to learn more. You are more than welcome to use any strap on any card, be happy wrecking your cards.

I see the following error now and then, after a Share has been found and where you would normally see the "Share accepted (xx ms)!" message:
XMR: 10/02/17-17:33:04 - SHARE FOUND - (GPU 2)
cannot find block data:
{"id":4,"jsonrpc":"2.0","result":null,"error":{"code":-1,"message":"Lowdifficultyshare"}}
cannot convert blob data
so what is happening here, is the share rejected from the pool or what?
Thanks!

P.S
The same problem. I already wrote about this

+1. same problem. would randomly get thiserro message. and I think it is affecting the effective hashrate in received by the pool?
