There was a bios expert posting a fair bit at https://litecointalk.org/index.php?topic=12369.0, you could try posting the bios there to see if the aggressive volt protection could be adjusted. I guess this won't help if powercolor skimped on the vrms though, what kind of vrm temps do you get with these cards with the low speed mining settings?

Very low, it's got some of the best vrm cooling I've seen. At such speeds around 50c.

It's great that you would come on here and warn people. Question is they a way you can easy tell what memory a gpu is using?

As others have said thanks for the warning its appreciated, as a side note how did you find the noise levels in heaven compared to the other custom cooled cards ?
Use the memory info test program: http://www.mediafire.com/download/voj4j1rlk0ucfz4/MemoryInfo+1005.rar
Or latest GPU z

I'd say it's the quietest and most powerful of any 290, but it's huge.
It's listed on their website as 266.65mm long, so it's actually quite short, and will fit in a lot more cases than the Sapphire, Windforce, or even the Asus, but at the expense of another slot for the thick cooler.
I was waiting on one of these myself, but got tempted by your MSI offer last week, which worked out £50 cheaper and was the more sensible option for me, but damn, the PCS+ does look tasty...

I think a price drop is the right thing to do Gibbo 
Wishful thinking haha. Seriously though chap, well done for warning potential buyers.

Yes there was a tool on the litecoin forum a poster linked to that can display this if you dont fancy popping your cooling solution off.

I think that's a given Walt.
This Gibbo guy knows what he's doing.
The OCP protection seen is not motherboard or its ability to apply good power through the PCi X slot.
The OCP protection is shutting the card down only due to high current draw on the VRM. A simple bios update to raise the bar on this protection may well be the easy fix implemented by Power Color.

Skim read this first and missed the Walt. Well played sir
Hope the price cuts come before powercolour has the chance to rectify it 
The question has-to be asked, why limit the VRM's like that, can they safely take more current draw?
was stress testing my msi gaming 290 frozr and had the same, using OCCT, after very mild oc (close to the oc out the box) the temps and fans rose as they should, then at 5min (same each time) the computer restarted, nothing was too high, no errors before etc - could this be similar issue?
BSOD restart, or more like flipping the power? If the former you can possibly tweak your way out of it, if the later then it could be the PSU is not up to it. That's if it boots itself back up after it forces the warm boot as the issue mentioned here seems to need the PC to be cold booted to clear the issue on the card once it locks to protect itself.
