Saphhire 7950 Vapor x OC settings

[dermo]

I have a mixture of 25 x 6970's and 35 x 7950 vapor x and 25 7950 OC

I run

1.15 V

Core 1040
Mem 1400

getting 605-615+ 24/7 stable with 1 rig out of 20 lock up about 1 every 10 days etc

I can get 640-650 out of cgminer but i prefer stability over an extra 4-5%

-thread-con 21712  i20 etc etc

Set GPU-PERCENT 100

~ 210watts per GPU

card & conf for 640-650 ? oO

I get avg 635 with 1150 core and 1500 mem on my 7950

Yes I read that one before, my same setting seamed to work for Feathercoin and I was getting way more block than I should the other day. Just a little pissed off that I still have no ltc block so far. It could just be bad luck.

i havent had a block in 3 days with 50,000kh going on it ( i normaly get 1 or 2 every day )

Well, mine is only 16.5 MH/s so that's like 1/3 of yours. But is it normal for you to have no blocks for that long usually? Or is it something changed in Litecoin block that we misconfigured with old settings?

i found 2 blocks over night so its still working
