Is this the IceQ 'Turbo' 1100 MHZ stock edition or the standard GHz?  I'll be picking one up soon, so thanks for the settings!

Sorry for the late reply. I looked up the correct name of my card, it's the turbo edition:

HIS Radeon R9 270X IceQ X2 Turbo; 1100 MHZ stock

I imagine the card and pc together, the card's specs up to 1902w. I've read most people are able to undervolt to around 1480.

Just saw your post, thanks for sharing!

A few hours ago I ordered 3 of them at €127 each (~ $175), expecting they would manage a little over 400KH/s. For that price tag and speed they should easily outperform the 7950s at KH/s per €uro.

Those 230 watts are for the card only or total for the entire PC?

Where did you get them for just 127€ Huh

I've got a HIS r9 270X IceQ2-whatever. Getting 470-480 kH/s without any errors with these setting:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://eu.middlecoin.com:3333 -u xxx -p xxx -w 256 -I 19 -g 1 --thread-concurrency 15232 --temp-target 70 --gpu-engine 1120 --gpu-memclock 1500 --lookup-gap 2

Running at 66°C, Fan 2150 RPM

Nice numbers you have there. Do you know what's the equivalent card to those on the Radeon 7xxx series?

Yup so title says most of it.

Long story short, saw bitcoin way back when.  Thought "wow that is neat".  I'm pretty sure I got a couple of coins after lots of mining.  Then decided to go look at how much they are worth, awww. why bother even transferring them out.

Fast forward to a month or so back - "Wow, wonder what my wallet address is, or my password...crap."  Well I wasn't counting on it, c'est la vie.

Anywhos, I was in the market for a "budget mid range GPU and saw the r9 270x and was impressed for the value-not expecting the world either.  Since it was an ati, figured I'd give a shot at mining.

First go with litecoin and cgminer - about 290kH/s - well I figured I could do better and read and followed the readme.

Here are my settings -- YMMV
Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

"C:\Users\YOURPATH\gminer\cgminer\cgminer.exe" --scrypt -u USER -p x -o [Suspicious link removed]:8888 --gpu-platform 0 -d 0 -w 256 -v 1 -I 18 -g 1 -l 1 --shaders 1280 --temp-target 77 --temp-overheat 81 --temp-cutoff 85 --auto-fan --auto-gpu --gpu-engine 840-1100 --gpu-memclock 1450 --thread-concurrency 14208 --no-submit-stale

That gives me about a 400-450 kH/s average drawing about 230w (old ass core-duo and windows Cool.    Anytime I start pushing the memclock or gpu engine much more I get little hashrate for the instability (about 4hrs max, before the driver dies).  I know a lot of people are poo-pooing the R9's, but I am impressed for a $200 card. I am still working on the settings periodically and am hoping for about 450-460kH/s stable, so for about $600 -> 1.2+ mH/s  that's not a terrible value from what I'm seeing on the market now (pretty sure that beats the r9 290x kHs/$.)

Just a lil FYI - hope someone finds this and can benefit from it as well.
