GUIMiner - passing extra flags to tune up GPUS

Hi, I'm using guiminer v0.04 with my 4xHD7850 rig (will upgrade it to 6x7850 soon - all GPUs are identical) and I'm wondering what is the correct way of passing these setting to cgminer used by guiminer:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
--gpu-engine XXXX

And what core clock XXXX setting I should try? What Mhz increments I should use from start and whether is there any danger of damaging units? (I think I'm not going to do anything with vddc BTW)

I want to check these settings

Code:

7850, HD7850-DC2-2GD5 362 1050 4800 1.135 Y 115 GUIMiner v0.04 -I 12 --thread-concurrency 8192 Windows 8.1 x64, 75C, i5-3570K, 16GB RAM, x16 risers

from litecoin.info.

My GPUs are Club3D Radeon HD7850 CoolStream 2GB (860/4800) - I will also appreciate well-working tips for this hardware - they are running 300 khash/s now(using -I 13, ATI catalyst 13.4, looks like these give best results), I think at least 10% increase is reachable.
