Just switch from phoenix/poclbm to cgminer. Gained about 10mhash/s in Windows, and 10-15mhash/s in Ubuntu
Really? Even Phoenix on phatk? I thought it was the most efficient.

You use cgminer if you mine in a pool that gives you a lot of stales and lacks basic features such as long polling. There is nothing that can beat the speed of phoenix w/ custom phatk kernel if you set it up right.
I get a better valid hashrate with cgminer 1.5.6 with -I 8. phateus just did the latest phatk for cgminer.
Yes and Phateus used diapolo's modifications as a base for his reworked kernel.
My overclocked 6970s are doing 460.5 MHash/s each on average, with peaks to 484+ and my stales are barely over 0.3%

Are you still running with your aggression around 6 or 7? I found that even though the reported hash rate went up, it didn't help my rate of accepted shares.
And dang, what clock speed are you running on your 6970s to get that hash rate?
Do you guys think it would be possible to run five 5870s on a Silverstone Strider Plus Gold 1000W PSU?
I have two Striders but they are only running 3 cards each. If I can get extender cables, I could add in more cards.
They're clocked at 950Mhz each, the max CCC will allow and the memory at stock. Accepted share rate is more dependent on latency to the server so there's not much you can do there. Take for example the recent i0coin mining rush. There was plenty of mining horsepower thrown at it, but it was people with low latency to the mining servers who managed to get the most shares in.
This one rig I'm posting on I have it in Eyefinity with 3x 1920x1200 24" monitors. Two HP LP2465s on the sides and a DELL U2410 in the middle. Obligatory eyefinity pr0n:
Nope never tried downclocking it though I should to try and save power, but...saving power is not really a concern for me lol . No extenders either, each rig has a pair of 6970s (2 rigs total) and I have third rig with a single 6950 that is getting upgraded to a 6970 as well.
And good lord I could almost cry seeing your hashrate . The things I could do with your setup if you let me tweak the shit out of it and squeeze every last MHash out of it.
Memory at stock? notice any differences when lower the memory clock ( if you've attempted to do that) Also are you using extenders?
Damn, I really have to do some tweaking, 1.8 MH/S to 2.2 MH/S with 6x 6950/6970's clocked at 925/600 is quite low

You'd be looking at like 1700 watt's
You mean gh/s
1.8 mh/s is quite terrible for 6x 6970s
I'm rocking 7x5830(have 8, 1 needs downclocked from 1000 before it can be added back), and 2x6950 unlocked shaders. Gets me 2.9gh/s. I have been wanting to add 8 more 5830/6870s for awhile now, might do it if Simplecoin keeps getting lucky.

6x6950 with unlocked shaders and slight overclock should get you 400mh/s. Overclocked 6970s should get you a bit more than that.
Wow, that's nice. I've heard many people say to never go below 300Mhz cause that tanked their hash rate. You must've gotten some primo silicon cards.
Just picked up a 6970 for $210 shipped. My upgrades are done for now. Next round's difficulty will be lower once again and coins are gaining value. It all almost seems too good to be true.

On other news, people are getting mad they can't get in on the action at mtgox. ROFL.
I'm running all my 5830s at 800/175, set with AMD's GPU Clock Tool (can't rely on Afterburner or Trixx for sh*t, except for custom profile fan control).Wow, that's nice.

Look at the volume at Tradehill compared to mtgox. No one is buying or selling at tradehill so people with coins are stuck. Their only other option is to move their coins to mtgox, but that takes hours and the rally at mtgox already stopped.
Thus:

Get the same hash rate as stock 800/1000, with a 50W reduction in power consumption at the wall per card

No, I can confirm that is what I read from the Kill-a-Watt. ~445W when running stock, ~348W when running the memory at 175. Keeps the cards a lot cooler as well.50w per 5830? That seems impossible. I am at 1000/300 on my 5830s, and they take up about 150w/card, if not a little bit more. No way dropping 200mhz on the ram is going to save me 100w.
BTW, what mhash are you getting on your 5830s?
I probably should (especially since I could easily get 960/175 stable for the lone 5830 in a single card system), but I'm pretty happy with the noise/temps right now and would like to run stock (with the exception of the RAM) for peace of mind.That makes sense
Should overclock those Extremes a bit, can get 300-320mhash out of them at 1000 core
Well, cgminer is also nice for it's GPU restart capabilities (or so I hear, which is why I'm running it).You use cgminer if you mine in a pool that gives you a lot of stales and lacks basic features such as long polling.
