Old veteran Rad 7950 miner here trying to get more out of this old ASUS 7970 3GD5, seen here: https://www.asus.com/Graphics_Cards/HD79703GD5/#specifications

Running Win 7 Pro 32 bit, here is some info:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

Card name: AMD Radeon HD 7900 Series
GPU: Tahiti
Bus Interface: PCI-E 3.0 x16 @ x16 1.1
Device Id: 1002-6798 : 1043-0418
Memory Size: 3072 MB
Shaders: 2048 Unified / DirectX 11.2
Driver Version: 9.2.0.0 Catalyst 12.10 (just changed it to 13.1)
BIOS Version: 015.012.000.004.000346
BIOS Part Number: 113-C3860100-101

cgminer 3.7.2 with -I 13 (above 13 gives HW errors, but we all know that by now.  Wink -g 1 (2 just slows it down) -w 256 --thread-concurrency 8192 (higher doesn't seem to yield any better perf.) --gpu-powertune 20 --lookup-gap 2

Core 1050, mem 1375 or 1500, I have tried core from 800 up to 1075 and mem from 1300 up to 1600-1700, 1375 and 1500 seems to work best for now.

I'm only getting 560 KH/s, any advice on how to make it up to 600, 650, 700+? Flash the BIOS, etc?
