Hi,
my graphic cards in Windows 10 64bit, Crimson 16.11.5, Claymore`s v9:
Asus Radeon Strix Gaming RX470 4GB - 190sol
Sapphire Radeon Nitro+ RX480 4GB - 214sol
Anyone advise me how to modify the bios for each of these cards? Link to youtube?
Thanks

Is it just me or is this version mostly geared towards the Pitcairns ( 7850 / 7870 / 270x / 370 )? Getting pretty much 25% speed up with these cards. The rest not so much.
Odd, I saw a 20% DROP give or take a hair on my 7850, pair of 7870s, 7750s, and A10-7890k
7870s for example dropped from 113 sol/s give or take to 87 sol/s
Might have to go back and recheck and see if v9 has a MUCH longer ramp up time than v8
THANKS A LOT CLAYMORE!!!

- SAPPHIRE NITRO+ (100406NT+4GOCL) RX 480 4GB model with V9 runs at 220 H/s at factory core 1306 / mem 1750 ( I think I can do better )
I tried pushing the mem over 2000 to duplicate other settings I saw posted on this thread but the PC crashed.

Memory clock speeds are not going to help you much with ZEC mining.
You're better off pushing the core to 1400 and you should reach around 240 / 250 h/s depending on how much you can squeeze.
Most speed gain from v9 getting Pitcarn,Tonga and RX series

Argh. Someone removed the page with all the gpu scores: https://en.m.wikibooks.org/wiki/ZCash_mining_GPU_Comparison
Does anyone have any screenshots or some way to retrieve the page??

280x is 215 sols solid on 15.12 drivers
Here's what I'm getting with v9.
R9 295x2 core 1100 mem 1500: 567 Sol/s
Nitro 470 8G core 1400 mem 2100: 233 Sol/s
All stock BIOS. Free electricity. Maybe I can push the cards more if I mod the BIOS and tighten mem timings.

Was 9.0 the last one or will you make another one! 
<3 Claymore!
Good question. We need an answer. I am wondering if he can get some more hashes out of hd7950 and especially from rx470 and rx480 <3 Claymore! v9.0 is not the last version, further speedup is possible. But don't expect another +30% in a couple of days please
Dear Claymore, Can you make the "UNIVERSAL MINER" with key -miner [Eth, XMR, Zec] (or something like that) managed by EthMan - to change mined coin operatively! Please)
It will make my miner's life easier)) I want to manage rigs from one EthMan by simple edit config.txt and restart miner) will not need to connect remotely to rigs and run another miner when the price of coins changes!
For RX 480 reference cards with 4gb flashed to 8gb stock bios..
v8 on rx 480 reference i got ~ 190s/s, but it would default to i 4
v9 on rx 480 reference i get ~ 220s/s, but intensity is now at i 6.
Still that is about ~15-16% difference.
I would like to note it seems a little bit more unstable...perhaps due to the intensity 6 default.
Will have to play with it a bit more.

Card was headless so I plugged a monitor to it, same speed. (ULPS is disabled for the card)
I have a Sapphire Fury running on same PC at 330 H/s using V9.
I see lots of references to bios mod's is the outcome the same as manually setting the Core and memory clocks in trixx or msi afterburner ?
Also I recall back in the day of Silt bios modes AMD was using signed bios's so it was reported to be impossible to modify bios without have a certificate to re-sign the bios file. Did AMD that drop that requirement ?

I think I found my I can't get better performance for this card (ref http://www.legitreviews.com/sapphire-nitro-radeon-rx-480-4gb-video-card-review_184553/10)
"This overclock meant that we were running at up to 1370 MHz at time and the memory was running at 1900 MHz (7600 MHz effective) on the 4GB of GDDR5 memory. Not the highest overclock in the world, but you have to keep in mind the reference cards boost speed is 1266MHz and the Nitro RX 480 4GB cards are the ‘fallout’ from the binning process done by Sapphire as the best chips become higher clocked Nitro RX 480 8GB cards.
We could not get 8000MHz effective clock speeds on the memory and Sapphire confirmed that the Radeon RX 480 4GB comes with slower Hynix GDDR5 memory chips and that hitting 8GHz would be unlikely. If we went much over 1900MHz the system would hard lock. If we overclocked much higher on the core the system would also lock up. We were able to get some games to run at 1385MHz with stability, but others would crash. At 1370MHz on the core we played a handful of games and they all were stable with this particular card"
v8 => 1215 H/s
v9 => 1425 H/s
rx470 : 190H/s
r9 fury : 330H/s

The furys got a good boost 270 underclocked to 311 at same settings

Thank you Claymore! 
~227 ea. on stock MSI 480 8g's - up from 193
I *really* appreciate your efforts.
Those of us who get it understand you should be rewarded for your hard work and stepping up and making things happen.
Please disregard the crybabies with a sense of entitlement who think the world owes them something for nothing.
Here's hoping you'll find continued success and keep turning out a great product we all benefit from.
cheers and thanks!
