4870 black screen high fan RPM problem - anyone else had this?

I have fixed my issue, by flashing the by now infamous Asus Top Bios Rev 01.

Fantastic stuff.

Not only that - I've had a large performance increase, too.

Idle temps are around 50°C, which is where I was previously getting all my crashes (at idle, not 50°!).

Big thumbs up from me.

Okay, update on this - yes, it has been an improvement over the stock BIOS, but now after 4 days my games are freezing up. No system crash, just games now - which, with the stock BIOS, were not affected - only crashes at idle, when starting or closing a program on the desktop.

So, it's time for me to reflash the original card BIOS, and go back to the e-tailer to see about a replacement, as it seems this is not as widespread as first thought. Or at least not something that ATi or MS seem interested in sorting out.

Can anyone else having this problem verify if they are using slot one or slot two PCI-E? The following thread shows some interesting info regarding the voltage settings for the "Northbridge" (couldn't post the thread so here's an extract of the convo) on our mobos bios. i think it might be relevant to our 4870 issue potentially. Anyone have any thoughts?


"Go into advanced in the bios and set ai overclocking(its at the top) to manual.Now go down the list to pci-e frequency,set it to 105.go further down the list to north bridge voltage,set it to 1.4.Reboot and see if that fixes it.

To you tpu guys,this is a well known error on the p5b/p5k series,there is lots about this in a p5b thread on xs forum."

How likely to blow up my pc is this lol?
