Knackered RAM

Car  Something Not French
Basically, I ordered 4 x 4Gb RAM upgrade for my late 2009 iMac from Scan.

Link : http://www.scan.co.uk/products/8gb-...0-(1066)-non-ecc-unbuffered-cas-7-7-7-20-150v

Apple Specs : http://support.apple.com/kb/SP576

Corsair : http://www.corsair.com/us/memory/ma...-ddr3-sodimm-memory-kit-cmsa8gx3m2a106c7.html

Arrived today, fitted, beeps and won't boot. Refitted, same, won't boot. After 30minutes of faffing and trying different combinations of the 4 chips, I tried them individually and no boot on any occasion. Refitted original 4Gb RAM, boots first time, works fine (on it now).

Rang Scan, they are arranging collection and test. Will take around 3 weeks to confirm whether is dead, but the advisor said "it was unlikely all 4 are dead." My thoughts precisely, but it seems to be true.

Any one else had a similar experience, or is it just bad luck?

Thanks for that. I was getting 2nd option, Ram doesn't pass data integrity.

Does this mean its incompatible, broken, other?
