The fastest RAM you can use are 204-pin 1066 MHz PC3-8500 DDR3 SO-DIMMs.
And modules with a heatsink won't fit.

That was all that was offered until last year. Honestly, the difference is unnoticeable. It would even be hard to notice the difference between DDR3 and DDR2, as the speeds are just that fast
Ahh okay that makes me feel better :-D obviously there is no way of getting into the bios to alter timings etc... I'm new to all this mac side of things that's all but thanks a bunch
Just trying to get the most out of mine, gonna fit an internal Blu-ray drive also I know they are more pricey but the whole idea of the iMac is it's uniform body... Don't want extra bits attached to it or I woulda bought a pc :-D

The 2009 i7 iMac will recognize DDR 1333 RAM. There was a thread on here where a guy swapped out his 1066 for 1333 RAM and he said the difference was noticeable. The system profile actually shows they are running at 1333 as well. I'm getting ready to make the upgrade myself from 8GB 1066 to 16GB 1333.
Hi Arkios,
Macs don't use BIOS but EFI (Extensible Firmware Interface).
You can't access or adjust anything (only with Firmware upgrades).

ahh okay,
well just been pricing up and i think al get 8gb of this 1333 stuff, i forgot its the so-dimm so just been browsing for prices
anyone recommend cheap places or good ram?
found some for £70 so far but not sure how much the latency effects the imac

Using faster memory won't increase performance at all. The computer will just slow down the ram's speed.
I don't understand your comments at all? If higher speed ram made no difference why was it created an why is it installed in the current generation of iMac? When it comes to simple computing I would agree but high intensity graphical applications would see an improvement?
Does anyone know if the ram I have linked would be any good or is it just cheap crap? Are Lattancys higher in so-dimm modules than standard dimm?

Some apps, although very few, can take advantage of such high memory bandwidths. Most commercial software can't. Technology develops even though most people don't notice the difference.
Seems to be compatible but the brand doesn't ring a bell in my head.

You might notice a ram bandwidth difference when gaming, and it might give you a couple more fps (like only 2-3), but that's about the only circumstance I could see for the average user.
Ram latency you probably won't notice either.
About the ONLY justification people have given for 1333mhz ram in their 09 iMcas was synthetic benchmark results.
