hi guys, any1 of u tried ocing the sapphire hd 4770 b4? I'm using riva tuner as ATI tool cudnt even recognize d card.... but having no luck with the riva tuner...can pump the core clock but once push the memory clock, d system goes black & nth happens...!?

use Catalyst Control Center to overclock la.

lol...dat works too but the CCC has limited the max clock to 830/850...from the default 750/800...was thinkin of making it 850/900 at least...hahaha

u need more voltage to sky high clock..

Apparently, i was told it gets really hot sometimes...my 4770 is at stock and am happy

the guys here cranked the card up to 880/985 without voltmod...so i think it is okay to oc d card up to around at least 850/900 or something...but mine ran into problem wif rivatuner, can crank up d core clock but cant push d mem clock..weird..was wondering if anyone has done it b4...

whats your temp reading at highest possible clock?

I only managed to push it to 830/850 wif CCC, wic is oso d limit given by CCC...temps on load is around 59C only

hmm 830/850 is quite good liao, temps are nice, make sure too keep it on that range 50-60 .. to test stable OC or not on GPU, try running some high intensif games like crysis or 3dmark06/vantage =/ or u can test it with OCCT GPU stress test, btw this thing will overheat ur gpu liao T_T

Try checkout RBE, if they got update for 4770 support.

and oc through bios flash.

love this method...last time i oced, using riva tuner will fix the clock to the value that we set (no resting time/downclock/powerplay isnt it?)
using bios flash can...

not sure they using voltage mod or not.. hvt read it yet..

Guys.. hows ur 4770 temp?? mine idle at 49-50c and load sometimes go till 69c (non air con. room)la.. opened side panel lagi.. was thinking how high will it be if i close it..

i have try it...use asus 4770 top bios....u can soft volt mod using asus software..then, push more..haha...very crazy performance la 4770 with it price..huhu

Har? using software to soft volt mod? can kah? using software...I tot must at least use pencil?

volt supplied can change in bios.. so using software should can..
asus developed one i suppose..

alright..finally able to crank d card up to 880/985 without voltmod...

guide to oc 4770 :
http://www.guru3d.com/article/overclocking...adeon-hd-4770/1

the riva can't dected your card because the software dont have configuration file for 4770

Download Rivatuner Radeon 4770 configuration file

after u have this configuration files , you should able to use riva

For my case the stock driver (6.14.10.6936) that comes with the GC somehow got some issue with overclocking...don't ask me why, i dont know coz evrytime i wanna up the mem clock wif riva, it will black screen. So i had to download version 6.14.10.6947.

Use riva instead of CCC, CCC oni limit d whole thing to 830/850. Riva version 2.24, mod the cfg file to include the GC information (here is the guide)

while overclocking, remember to have the CCC on but use Riva to adjust ur clock...

wow amazing result u got there. actually i'm now aiming at tis xfx hd4770 HD-477A-YDFC wif a different cooler. i saw it ady on sales in oversea. waiting for it to arrive local market. hehe
