ISO grain on my 5D

I went over to full frame last year with a 5D and for the most part I am very happy with it, with one exception, when I put the ISO to 400 or higher the pics seem very grainy to me, far more so than with my 40D or my old 20D.

Is this common? And if it isn't, is it a problem that Canon might be able to fix? I don't want to get rid of the camera as I love full frame but I can't always have the sort of light where I shoot with ISO100 or 200 and I need minimal grain for most of my portraiture work.

All thoughts appreciated
 
5D up to ISO 1600 is superb, perhaps yours is broken.
 
the 5D can be a little grainy, and actually the 30D was pretty good with noise. When both cameras came out at the same time comparisons were similar. The reason the 5D shows some grain at low ISO compared to modern cameras is the amount of in-camera noise reduction performed - the 5D has very little. This and the weak aa filter give the images something different. The grainyness though, is very easy to correct with tiny amounts of noise reduction using something like lightroom, even at 3200 you don't need much to make nice smooth images with little loss of detail.
 
I have a 5D and 5D2,
IMO the 5D has less noise until ISO 1600, at which point the 5D2 edges it, but both have little to no real noise visible, unless you are at 100% zoom and looking for it!

I will generally process a 5D RAW file upto ISO 1000 with no NR at all...

As has been said, an example would be good to see
 
Got highlight priority mode enabled? If so disable it as it creates noise even at 200 (lowest iso setting with it enabled) -.-

Doesn't apply to old 5D. Pre-digicIII cameras didn't have such settings.
