Yes.
In Catalyst 7.7, I reach maximum VPU and Mem clock at 850/1035.
In Catalyst 7.8, I reach maximum VPU and Mem clock at 860/1051.
I think that pretty good.
I tested Catalyst 7.8 with my Palit HD2600XT. The result is very well improvement.
With Catalyst 7.7 I get 97XX point in 3Dmark2005. With Catalyst 7.8 I get 103XX point.
It improve about 4-6%.
I have Palit HD2600XT Xtreme. The stock clock VPU/Ram = 800/800. Now I can overclock to 820/1030 using Rivatunner. But When I tried to mod bios with Rabit. The program is fault and said that it didn't know the bios of HD2600XT.
I tried with Rabit 2.2.1 but I still not work. Anybody can mod...
I have the same problem with Catalyst 7.5
My system is
AMD64 3000+
ASUS A8N SLI Deluxe
Kington DDR400 512MB*2
Sapphire X1650XT
Windows XP SP2
When I install CCC 7.5 and restart. The window screen at resolution = 1440*900 was totally blank. The monitor said that no signal input.
But...
I have Sapphire X1650XT.
My CPU is AMD64 3000+@2.66GHz with 512 MB DDR500(256MB*2)
3Dmark 2001 = 22000
3Dmark 2003 = 12000
3Dmark 2005 = 7600
3Dmark 2006 = 3250
But I cannot OC by using Catalyst 7.1. That is very odd.
I had the same problem with Catalyst 7.1.
I use X1650XT. When I adjust vpu clock or mem clock, the monitor will be flickering scree.
This effect didn't occure in catalyst 6.10.
This night, I will be tried with Omegadriver.
