Right, well underlined... Memory speed affects hashrate a lot with ltc mining. I ran memory at default speeds which meant I also had to turn my gpu engine overclock speeds down slightly to not crash.
Oh yes and driver 12.6 worked the least worst on my 7970s, though it was truly easy to crash with the wrong settings so I rebooted literally dozens of times...
I was actually surprised after your initial warning, as I only crashed 1 out of 5 rigs due to low voltage, as I am still trying to conserve as much power as possible and everything is undervolted and memory-underclocked.
I found it smooth.....
GL with that.

If other cards like intensity 14, then I should change the scale.
In Reaper, 7970s would ONLY run well using 13 Intensity, whereas 5/6xxx cards benefited from up to 19 for dedicated rigs and saw huge performance increases at higher intensities.....
Reaper Aggression = CGMiner Intensity ?
#define MAX_INTENSITY 14
#define _MAX_INTENSITY_STR "14"
and change those 14s to 20 or something.
if you are not happy with what you already have....do it yourself.
big thx ckolivas for the good work.
*already sent btc for cgminer now working for cgminer-ltc*
:-P

I should have also added, that I am using Cat 12.6 / SDK 2.6 on EVERY rig...5/6/7xxx setups.
What I have noticed:
- 5/6xxx Cards like -I 14
- 7970 does not like Intensity over 13.
- Thread_concurrency of 4096 and LESS (by either 512 or 1024 increments) as low as 2048 seem to work well for anything from a 5770 to a 6950.

Hmm, 12.2CCC and 2.5SDK here, and at intensity 13 my 5770 gets "sick" after awhile, and at intensity 14 cgminer crashes. Also I bluescreened doing intensity 13 on my 6850, and got error code 0x3b. I'm gonna try 12.6 again

My hash rates look good...but is Solo Mining broken by chance ? .........either that, or my luck just took a huge turn for the worst, especially considering the hashing capabilities I have at the moment...lol
..and of course, as soon as I return back to my miners after posting this, I get a block...LOL
Everything looks good over here.

Anything *might* be broken still at this early stage. You tell me how often you'd get a block and whether it's about right or not...and of course, as soon as I return back to my miners after posting this, I get a block...LOL

my 6870 mined fastest at aggression 17 or 18, for reaper anyway

For those reporting lower hash rates with cgminer vs reaper - I thought it had already been established that the hash rate self-reported by cgminer is not directly comparable to the hash rate self-reported by reaper (i.e. you can't just compare the hash rates on the screen and conclude that one is faster than the other).
To compare speed you have to compare share submission rates, or compare the hash rate reported by your pool, which is calculated based on your share submission rate.

I'm getting 9 times lower speed with it, than with reaper. 21 vs 190 kh/s. 
Tried command line above and as well with my thread-concurrency.

Tried with Cgminer, i never used cgminer before, used this command line arguments & getting 346 MH/s
cgminer.exe --url http://notroll.in:6332 --userpass xxxx:xxx -I 9
It seems Cgminer reporting in MH/s while reaper in kH/s
Increased I to 12 & see same 345 Mh/s
cgminer.exe --url http://notroll.in:6332 --userpass xxxx:xxx -I 9

you are trying to mine bitcoin on a litecoin pool lol
for ltc you need to put --scrypt --lookup-gap 2 --thread-concurrency 8192 -g 4 -I 13
and edit the other settings
ooops..., thanks

yah thats weird if i set mine to 14 it gets tons of rejects what card and settings were you using??
i use 2*6770, but only testing on 1, i use
Code:
cgminer --scrypt -o http://****:**** -u ** -p ** --worksize 256 --lookup-gap 2 --thread-concurrency 6144 -I 14 -g 1
and O/C is set to 950/1300
yah thats weird if i set mine to 14 it gets tons of rejects what card and settings were you using??
Don't go over intensity 13. Other than that, you're all on your own to experiment. It is slightly different to raper[sic] so it will need different parameters.
why not over 13?, if i set mine to 14 i get more kh/s and shares then i do on 13, and i do not get more stales while setting at 14 ?
