I'm having a bit of trouble tuning my two Saphire 7870 OC Edition, which is a Pitcairn not a Tahiti. I've seen that others are getting as high as 420 on their Pitcairns, but I haven't been able to find their exact config.
I'm getting ~380k each, but my WU are pretty low, at 259 and 280. Here's the output from cgminer:
cgminer version 3.4.3 - Started: [2013-12-03 06:09:26] -------------------------------------------------------------------------------- (5s):707.2K (avg):757.7Kh/s | A:54284 R:1228 HW:248 WU:540.1/m ST: 1 SS: 0 NB: 50 LW: 610 GF: 0 RF: 0 Connected to stratum.mypool.com diff 215 with stratum as user myuser.x Block: 8eed9c63b68cdb8c...

Here's a copy of my cgminer.conf:
{ "pools" : [ { "url" : "stratum+tcp://stratum.mypool.com:3333", "user" : "myusername.x", "pass" : "mypass" } ] , "intensity" : "20", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "11520", "shaders" : "1024", "expiry" : "120", "auto-fan" : true, "gpu-dyninterval" : "7", "gpu-threads" : "1", "gpu-powertune" : "-5,-5", "gpu-engine" : "900", "gpu-memclock" : "1250", "gpu-fan" : "65", "log" : "5", "no-pool-disable" : true, "queue" : "0", "scan-time" : "30", "scrypt" : true, "shares" : "0", "kernel-path" : "/usr/local/bin" }
I'm gonna give a tip of the extra earnings for 10 days to anyone who can help me increase my hashrate.
