Powercolor 290x LCS Hashrate

[Megabit monster]

Hey guys,

I'm fairly new to GPU mining and am wondering why I can't seem to get more than 830kh/s on my power color 290x cards.  These are primarily for gaming but when they aren't used for gaming I've been mining with them.  Link to card specs = http://www.powercolor.com/us/products_features.asp?id=521

They never get above 65c and my water loop is solid. 

Here is my config file.  Any tips/pointers would be greatly appreciated and if you can get me over 900k a nice donation will be made to you in BTC. I have afterburner undervolting the cards at -31. It seems these do better when undervolted. I am using dual 1000w platinum power supplies.

Ya We've got some PC 290 (non-x), and they get pretty mediocre hashrates. Tell me, does yours have Elpida ram?

Yeah they are all elpida. I will say they are pretty amazing for gaming lol

The best tip I can give you is to play with your settings, all of them, until you find the ones that give you the most WU.

Start by tuning your TC (should be a multiplier of your shaders +1 - usually, mine is just a multiplier of the shaders) as well as your gpu-threads and after this move to worksize.
Your next step is to up your mem clock until you see a decline in KH/s and then turn it down a notch. Then go tune the gpu core, some cards will like it faster, others will like it slower, same deal here, tune it until you see a decline in performance, and than take back a notch.

I recommend you do this all in stock voltage, and only after you find settings you like, undervolt it.

Or you could always try and copy others settings, or at the very least, start tweaking from there: https://litecoin.info/Mining_hardware_comparison

My card has normal setting and uber setting dual bios. Should I be using the normal or uber mode bios?

If memory serves me right, uber settings is just overclocked speeds, so for mining, it's completely useless since we adjust the speeds anyway via afterburner or the likes, in order to find the optimal settings that fits us.

So to answer your question, it doesn't matter, but I'd personally start with the normal mode.
