ASUS Radeon 5850 HD Overclocking help!

[crunzaty]

Hey, i need some help clocking my EAH5850/2DIS/1GD5
I have MSI Afterburner and ASUS SmartDoctor.

I have tried clocking it after a youtube video that said that 5000 Memory 1000 core and 1.35 Vcore would work.
Youtube vid: http://www.youtube.com/watch?v=-301mvSNyUI&videos=8Izd2vcIgDM
I have tried clocking it after ASUS 5870 to but it did not work either :<
And it wont work. Do any1 know what the problem can be? how can i fix it?

I want to clock it to atlest ASUS Radeon 5870..
Thanks for your time!

firstly, whomever posted that youtube video is an idiot.

all chips are different, and what works for some may not work for others (and can even be dangerous)

you need to make sure you know how overclocking works, and exactly what you are doing. overclock in increments and stability test while constantly monitoring temps. dont just go whacking up the voltage, thats how you fry a GPU.

some chips cannot overclock at all (very few, but it can happen) and others can get insane overclocks. they are all different. the scale of circuitry makes consistency impossible.

now what settings have you tried?

all i could say is read some guides, or esle break something. make sure to download MSI Kombustor, HW monitor, GPUz and whatever OCing tool you prefer (i use MSI afterburner)

and again, overclock in increments, check temps and run a stress test before trying the next clock increase. raise voltage only as needed, and every time you do be sure to monitor temps carefully.

I have tried:
800 Core x 1200 Memory x 1.15 Vcore
And some others. They all worked at IDLE a long time but got fucked up when i tried "stresstest".
I hope its possible to get it up to 800 / 1200 or 5870 values.

I use FurMark as "stresstest" and check's the temp with SmartDoctor by ASUS
I'll download the rest of them asap :]

Any tips?
