HIS 5850 OC

[manky]

Hi

First sorry for my noobness. I haven't bought a decent PC for years so not had any overclocking experience.

I bought a Titan Onyx with HIS iCooler V ATI Radeon HD 5850 1024MB GDDR5 PCI-Express Graphics Card.

I want to overclock it. I have all the tools downloaded and an Asus Bios from Techpowerup (THIS ONE). I am going to flash in DOS with atiflash.

Couple of questions before I proceed:

1) Is that the best BIOS for this card?

2) I've seen peoples comments regarding MSI Afterburner not allowing voltage increases and defaulting to stock speeds - do I need to do something 'special' to MSI Afterburner?

Thanks in advance if you can help.

Cheers

Becareful, almost BIOS on TechPowerup is reference card, I think your His iCooler is not reference card.

Ok - I was wondering that!! So I cannot update BIOS on that card with a reference BIOS?

Am I stuck to overclocking memory and GPU without voltage?

I found this comment on another site:

"I bought this HIS Radeon 5850 last week and i must say its the best GPU ive owned in years, it does 1000Mhz on the core clock with a mere 1.2v of vCore, full load temps with fan at 50% never exceeds 67 degrees Celsius."

How do I increase voltage?

Use MSI After Burner!

As far as I know, if it's a non-reference card, you can't flash it with a reference bios (well technically you can, but you'll end up with an expensive door-stop).

Also you cannot increase the voltage to the same levels as the refs, they left some hardware out with the non-refs.

Ok thanks for your replys!

Can anyone who owns one of these cards that has overclocked it let me know the procedure that was followed?

Do I need to edit MSI Afterburners cfg file to enable any changes?

I was under the impression that this cards voltage could be changed - but it seems apparently this is not the case... damn!

You can always try Afterburner, can't harm the card; you may have to check "unlock voltage control" in the settings.

Ok thanks

Ok thanks

Let us know how you get on.

when i tryed to submit my bios to their database (there was no icooler version on there), it refused saying there was already a bios uploaded for it and it pointed me to a reference bios
Cannot help with this thread as i havent overclocked mine its only 2 weeks old besides that why would i try to fry it already???

This thread seems to indicate that the MSI Bios from a 5870 will work with no issues....

Still problems with the voltage though.

Try to find a tech drawing of the card or spec sheet and find out what voltage regulation circuitry it uses then you can add the line of code to msi afterburner to allow upto .1 volt voltage adjustment.

thats what i had to do with my 5850 direct cu PITA but it works
