What hash rate can I expect from 3 x 7850s?

[Operatr]

Ive been mining litecoin so im not too sure how the numbers compare.

I have 3x 7850 @ 1100 Core/1200 Memory, average around 380KH/s each

./cgminer --lookup-gap 2 -I 20 --thread-concurrency 8192 -w 256

Thanks for the specs, I in cgminer Im rolling around 320 Khash/s each with similar settings, I will try this config and see if it improves.

With 1100 clock/1250 mem 1.46 vcore    and   --intensity 14 --lookup-gap 2 --thread-concurrency 8192 --worksize 256 -g 1     I am able to pull in around 370 KHash/s mining Litecoin without any stability issues or cgminer errors, averaging 955 KHash/s with 3 cards.

Running 2 rigs (soon to be 4 rigs) with 4 7850s each.

Each GPU gets 320 M/hash at 1095 OC. For a 24/7 operation I cant get them to go higher. Also its open air non cased, in front of a window AC unit.....

7850's are the best bang for buck, unless you can get 7950's on sale.

what's the PSU your are using to power up these 4 together.

BTW which 7850 still have undervolt feature available or are they all locked now?

Bitcoin - I can get about 330MH/s off the 7850 vs 430-450MH/s on the 7970's
LTC - I can get close to 400KH/s on the 7850

The 7870's have some kind of issue I haven't resolved yet but so far they are mostly BTC.  I've seen 550-750KH/s (depends on intensity) off the pair but the actual work completed (U: score)  is closer to 350KH/s.

For the record, running stable at 341.9Mh/s. Still experimenting.

FWIW my ASUS HD7850-DC2-2GD5-V2 is giving 331Mh/s. This is with 1100 engine, 950 memory, intensity 7, diablo kernel under CGminer 3.1. Temp is running 60C.

I'm able to get around 360 kHash per card with moderate OC in Scrypt mining with my 7850s, could probably get that up more with some better cooling.
