As long as the miner is working on zcashd for solo mining that would be great. The new release gpu miner can only work on a pool(as i understand). Hope @voxelot, @Age, @omaralv can have it working before zcash release. We have a lot more time after the 28th to optimize.

We will be solo mining on launch. I don’t know if we will have time to add pool support. We will also be making a PR to zcash so that all you will need is a -GPU flag in config to use our miner.
I will probably not be very responsive until launch. We have very ambitious plans for the next three days.
Woot!

BIOS mod refers to copying the of the 1500 straps to the higher frequencies. A shameless self-promotion guide can be found here: http://cryptoyeti.com/rx470-bios-mod/
But be careful as this type of tweaking should be left to experienced users and may void your warranty and/or could even brick your GPU. You have been warned. 
Ah, nice. Yeah I am leaning towards the 470 cards now. Going to order 100 of them so I want to do my research.
However. What I am considering is the 4GB vs 8GB version. The 8GB version is about 10% more epxensive. Do you get 10% more performance? That is the question.

Bios mod is not only the memory straps, you would change core clock, mem clock and TDP; Even default fan settings. Either to adapt the card to specific requirements for a particular coin or just because there is no software allowing you to do so on linux for RX cards like wattman in windows.
Performance wise, it’s about +10% for RX 480 but higher consumption too.
Yes… for ETH
memory clock >
@lexele I mean that the RX470 8GB is about 10% more epxensive compared to the RX470 4GB version.
Is the 470 8GB 10% better performance compared to the 470 4GB. That is the question.
I have found the 8 GB cards to be a bit more than 15% price-wise for maybe 10% performance. Also the power consumption is a bit lower with the RX470s. Of course this all boils down to how you tweak the settings, but I look for a performance versus power trade-off.
Yeah I am leaning towards the Sapphire Nitro RX470 8GB cards with the new quick connect/replace fans.

Hello, this only works with AMD GPUs?
Hey gang, what pool are you testing zogminer on? I have tested 3 cards so far, by logging into supernova. However I am not seeing my miner as hashing on supr in my dashboard. I do see my card hashing in the Terminal. The only real successful card so far is an R9 390. seems to be hashing around 18 or so. My 480 starts but freezing up Ubuntu, and I tried a 7790 for fun and giggles it just runs that steady stream “Running Equihash solver with nNonce” repeatedly… not hashing. ok, just want to see my hash on a pool… any suggestions or is there any?

Important to remember here is that there is active discussion in the zcash team regarding making the algo more memory hard, which could bump 2GB, and possibly 4GB cards out of the race. Worth reading up on if you are about to spend money on GPU’s.

Thanks for that info DanLar75! This makes me lean towards the 8GB version even more!
Don’t thank me yet, read up on their proposed changes. I haven’t researched it in depth, just pointing out that there might be a risk.
There’s virtually no risk to the 4GB cards.
I hear ya
So skimming through the post… launch will be solo mining as it stands then, which is good for now if so.
edit… solo and pool perhaps lol

Running the test miner
ERROR: No suitable GPU found! No work will be performed!
wath happen?
Zogminer solutions now officially pass zcash’s requirements and are ready to mine on test-net. Once Omar wakes up he will complete the solution to block needed for mining.
I am going to focus on improving the solution kernel.
Cheers!

Outstanding work! You still have 2 days to the contest deadline too.
