Hi, I'm getting 2.7Mh on my R9 280x mining Boostcoin on x13mod. Is that about right?
it was 2.65 now 2.7?

it's k anyway, i'm at 2.55 on default settings(1100core)
Hehe yeah, I was doing 2.65 @ 1200/1500, now running 1210/1800 seemed to have given a little bit more juice

As far as I can see on these forums, it seems to be pretty okay.
I running it on my PC only at the moment. My mining rig (6x Asus R9 280X DC2T-3GD5) is running on Pimp 1.4 (which doesn't support x13 yet). I'm going to upgrade to 1.4.2, that should allow me to run x13, yet at lower speeds until they implement the mod.
EDIT: 2.73 @ 1225/1800. Been running stable for a while now. Don't think I'll push it higher, it'll just crash the driver.
