Not working with my 6 GPU rigs unfortunately (only 4 GPUs are usable). The drivers will need to be modded if you have 5+ GPUs.

However, this *should* work, I haven't had a chance to try it yet:

I attempted to follow along from the original post and made this for the "14.6-Beta-V1.0-Windows-May23" download that you can grab currently from AMD. I only made 2 .infs that replaced the two in \Packages\Drivers\Display\WB6A_INF.

I initially tried it without cleaning out the files and it failed. I would recommend following the OP's post on clearing out the files here: https://litecointalk.org/index.php?topic=11001.msg79830#msg79830

I installed the same way as suggested in that post. I installed with fewer than 3 cards installed at the time. Afterwards I hooked the rest of them up and finally had 6 cards (r9 270s on Windows 8.1) working. I needed the 14.6 drivers as this miner: https://bitcointalk.org/index.php?topic=658411 is optimized for them and now my r9 270s are hashing ~2.5-2.7 Mh/s on x11mod kernel.

Anyhow, try these at your own risk: http://www.filedropper.com/146modtest * fixed link

Same experience only get 5 290 GPUs on a Asrock Bitcoin Board with 14.6.
