no under voltage

Claymore, why I 7850 1GB card speed of only 120 H/S, and 7850 of my 2GB card to 220H/S, the same configuration
Miner requires a lot of GPU RAM. For full speed 3GB is required for 290/290X/280X and 2GB for 270/270X.
If miner cannot find 2 GB it will work with 1 GB but much slower.
Note that if something is wrong with memory allocation miner won't work a bit slower, it will work much slower (in 1.5 - 2 times), so if someone has 400h/s instead of 450h/s - memory allocation is not the reason.
my 7950 rig has 8 gig at current, added more last night to see if that helped with the drop out issue, which it didnt sadly.

despite the random card dropping, OC seems to be very straight forward.... getting 302.5H/s per 7950.....
How the hell did you do that?
I have a Sapphire 7970 which can not reach 280h / s
I'm using 13.12 drivers

Dev add Aeon coin 
thks
thks here is what 5 x 270x looks like
What is the driver version do you use?
13.251.0.0
Please tell me there is a fix in the works for the miner dropping cards randomly. this is hell fustrateing.

Maybe http://monero.crypto-pool.fr/ # and developer and have to cut a small fee.
Small miners it was 7% in total. And even if graphics do not reach the speed that you cited.
I understand that I am free to switch to another coin.
Just a suggestion.
I now get to 6x 7970 and barely Add the 1400K now your rates and price of electricity.

To be exact :
Claymore take 5% of your hashing power.
The pool take (95%*98%)-95%=1.9% of your hashing power.
Both take together 6.9% (not 7%) of your hashing power.
So Claymore fees represent 62% of the total fees and the pool represent 38% of the total fees.
I'm just clarifying things, don't mind me. I just like when it is precise.

3x 290 1606h/s almost 6 hours rock solid
What are your settings like? Try to run miner with "-dbg 1" option and when all cards stop work post a screenshot here.
No crash But this show up after 10 mints
Numbers changing fast
will keep you up to date.
What if you assign only one CPU core to miner (affinity in task manager)? Same problem?
Yes lower H down to 650 from 890 and got the same Numbers 10 min later :/
In next update I will add some more debug output, but it seems this problem is related to OpenCL driver somehow, not to miner, but probably I can find some workaround...

it looks like the Ram Mine is Only 4GB 
and virtual memory set to 40 Gb
and virtual memory set to 40 Gb
can u please tell me your OC and are u under voltage or not ??
no OC and no under voltage - just all cards running with stock settings.
the rig is now running fine, almost 3 hours and stable with this hashrate (~1330 h/s)
that's weird have same setup up got only 890 h
How much Ram do you have ??
16GB RAM, a fast 128GB SSD (Samsung ~500 GB/s for R/W)
virtual memory set to 32768 kb - 65536 kb
and a i7-4770K @4GH OC on a MSI Z87GD65 (Gaming & OC board)
Windows 8.1 pro 64 bit
on the same system I'm runnig wolfs cpu miner with 4 threads giving me additional ~190 h/s
