Any PowerColor HD4850 Play user here?  After so many post I've been through, I can see that you all can easily clock your HD4850 to 700/1100. I'm using Catalyst 8.12 downloaded from official website, and max I can go is like 680/1020 like that only. I'm using: Q6600 @ stock G31M-ES2L @ F4 bios Corsair XMS2 800 4GB @ stock CM Extreme 500w Vista Ultimate 32bit So I'm wondering is it my PSU not enough to give power if I wanted to clock the card, as well as the other hardwares?

Question (again): Regarding to bios flashing, I've found this. QUOTE(Overclock.net) Hey guys here is some of the OC ready bios for 4850 and 4870 round up! All have been test work perfectly. 3D mark vantage rise by 500mark on hard OC 4850, and 1000Mark on hard OC 4870 ( On my system )
I> 4850 BIOS
1. HD4850 Hard Overclocked. DF Core 750MHz Mem 1100MHz Auto Cool Fan.
GPU Core upper Limit 850MHz
Memory Upper limit 1300MHz
Vcore Modded to 1.175V for hard Overclocking.

2. HD4850 Light Overclocked. DF Core 700MHz Mem 1000MHz Auto Cool Fan.
GPU Core upper Limit 850MHz
Memory Upper limit 1300MHz
Vcore DF 1.12V
LINK
HD4850 only Upper limit. DF Core 625MHz Mem 993MHz Auto Cool Fan.
GPU Core upper Limit 950MHz
Memory Upper limit 1400MHz
Vcore DF 1.12V
LINK
HD4850 only Upper limit. DF Core 625MHz Mem 993MHz.
GPU Core upper Limit 1250MHz
Memory Upper limit 1450MHz
Vcore DF 1.12V
LINK Source: Overclock.netDoes that mean that once we flash the bios, we can get that particular stock clock already? Does that applies on all the HD4850 in the market? Or does it pointed to certain brand only? Sorry if I'm asking stupid questions as I'm still on the road on learningThis post has been edited by Shufflerz: Jan 28 2009, 05:39 PM |

I'm using CCC to set the core/mem clock of my gpu. But after I press Apply, and I run GPU-Z, the GPU Clock still remain the same as the Default Clock. Check this out. 
Any idea what's going on? This post has been edited by Shufflerz: Jan 29 2009, 10:49 AM |
