ATI's RD580...LDT overclocking TO THE MAX.

well, let the picture say it all...not many have been able to acheive this yet.

Is overclocking LDT this high likely to benefit everyone or is it just going to be beneficial to people with multiple GPUs, high speed memory and high bandwidth devices?

I have recently tried increasing the speed of my PCI-E bus, and dicovered that anything upto 110MHz makes a slight improvement but above this yeilds no difference whatsoever and above 120MHz results in instability, I accept that this is probably due to the fact my GPU is not high-end equipment, a lot of people neglect overclocking the various transport buses and I'm wondering if people with very high-end hardware could be benefiting more through doing this.

I don't know much about how well current equipment saturates the buses bandwidth wise...what are your thoughts?

I definately gota boost from it...mind you I am running 2 vids and physics card, as well as X-FI. ONe of the few times that the bus gets saturated is at start-up, and this is a bit faster.

PCi-e bus...increasing that will allow your videocard to clock higher. abt 115mhz seems to be a sweetspot for ATI, while nVidia seems to like 120+. All the top benchmark scores use a higher-than-default pci-e speed.
