Glad to announce:
Sapphire HD5770 Vapor-X stable OC @ 950core/1320mem, running full reso on 1600x900 temp at stable 65C@65% fan spd (gaming), 75C@70% fan spd (MSI Kombustor)
Thx for all who guided me especially the big tip from JoBigShow!

haha..no prob
This card was meant to be overclocked in the first place....

Anyways, when you are not playing games, do reset the clocks back to stock, or else the clock won't idle low, it will stuck at that OC speed throughout the duration of the time...

Oh but it does idle at low clock speed currently at 157/300 hehe now using 10.4 driver only so its ok

how do u guys solve the Overclock high idle clock speed issue?

i wan to use catalyst 10.7a and overclock my card in the mean time maintaining the low idle clock speed

not possible?

refer to this one, the only way ATM I think?

is there any new card coming?
boring ler idle quite sometimes..

That's why i am wondering if there is different btw manufacturer and official ATI? Who knows, the manufacturer twist the driver a bit and work great for their card?

based on my experience with Asus And Sapphire cards, no i dont think the driver that you can download in their website is modified so it will perform better.

There are rumors on the Southern Islands (HD6xxx) is thats what ur looking for otherwise its just new editions of previous cards (check Sapphire HD5770 flex)

i see nvidia is moving forward..
no much info on ati camp.. still the price is stable right now..

guys, noob here, is there difference in the radeon hd 5670 between ati, xfx and sapphire? or is it just the built?

The chips used are the same
Just that different manufacturers have different types of PCBs, cooling and etc etc

Main chip is same provided by ATI. They just change on the designs and fans. Both company also is Asian based one.

having a sponsor has its advantages..

I think occasionally some may differ in the output connectors.

I'm kinda confused here. You said that the clock didn't stay (after you overclock) infact it downclock to 157/300 when idle?

It's not possible with MSI afterburner for sure. The only way you can achieve that is by modding the GC bios. I'm sorry if I said anything wrong. Enlighten me please.

There u go, just so u know, I also dunno y this can happen when everyone says it shouldn't downclock

this happened at their HD2600XT before,no official driver will fix the bugs..only driver from sapphire site will do..

Found the answer for it. It seems like 10.5 onwards ATI messed up with the driver. But I guess your fan speed stays the same (before and after you push your GPU)

this is because you havent change anything yet in msi afterburner, you just open it and thats all. If you change it and click apply, it will stay at your defined setting, it wont downclock itself
