Topic: CGMiner not mininng enough (Read 472 times)

I built a new gaming PC and used the motherboard, cpu (G530 Celeron), power supply, and GPUs (2 HIS Ice-Q 7950's)from one of my mining PCs for it.  I used different RAM sticks totaling 16 GB of RAM.

I Copy and Pasted the CGminer 3.30 from a flash drive into the new computer.  I added my new pool info in place of the old pool.  Still using Windows 7 Pro 64 bit.

But it won't mine as much.  I used to be able to get 630 Khash easily, and push it to 660.  Now I can barely get 570.  Even at powertune +20 and MSI Afterburner at +20 on Powertune.
Here's my CGminer config file code:

timeout /t 2
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o xxxxxxxxxxxxxxxxxxxxxxx (minus my pool info and user info)
-I 12 -w 256 --thread-concurrency 24064,24064 --shaders 1792,1792 --gpu-engine 1000,1000 --gpu-memclock 1250,1250

When pushed as hard as 1070/1475 and intensity 19, I'd get 630 Khash, but now it won't go over 570 at best.

I tried different TC's, different clock settings, but nothing got over 570.

I tried putting --powertune 20 and -gpu 2 in the settings but that didn't help.

Any ideas what's wrong?  Some might say that since the RAM is the only difference then that's it, but I don't see how that would be the problem, it's 1600 speed RAM and 16 GB, vs the 6 GB it had before.

And even though I have the intensity set at 12, it always starts as 8.  The MSI Afterburner software is also cranked up, but it keeps starting at 8 intensity and I have to readjust it.
