Sapphire HD4670 1GB over clockability

Last response: in Graphics & Displays

Good day to everyone!!

I would like to get some advise on Bios updating. As my Video card has VERY limited room for over clocking.

Would updating the Bios possibly improve its over clocking potential? The GPU can be OC'd up to 65Mhz but the memory refuses to be OC'd over 20Mhz. Is this how this card really is or is there someway I can get more performance out of it?

Please help out! :D 

Thank you in advance and more power!

If there is a bios update for your card from Sapphire, do it. Check beforehand with GPU-Z that the bios is the correct one for your card and backup your old bios (very important).
If it fails put a second video card (PCIe or PCI or AGP) in and reflash.
No guarantee it will improve overclocking though.

Alright! :D  Thanks mate!

Hmmm... I was thinking if it was possible to flash the 1GB card with the bios of the 512MB card as the 512MB card comes with faster memory would it adversely affect the card?
