geekbench no difference between 4 and 8 GB Ram?
I just upgraded my iMac i7 to 8GB Ram and ran geekbench again but there was no difference to the prior 4GB setup.. even in 64bit it doesn't make a difference.
does anyone know if it is normal or is there something wrong with my Ram?
the pics show the results
32bit 4GB -> 8396
64bit 4GB -> 9649
32bit 8GB -> 8386
64bit 8GB -> 9605

Geekbench does nothing to score based on RAM capacity, just the memory bandwidth and to a certain extent RAM timings (CL7 vs CL9). You will however see vast improvements if you use a lot of fairly intensive programs, especially in multitasking situations. I had 8GB in my old Power Mac before this and I was frequently Using/Caching most of it.
However in my experience of upgrading to 1333MHz RAM, the bandwidth-dependent tests went up by about 25% under both 32-bit and 64-bit, although the overall memory score increased only slightly because the other tests did about the same or worse. I also doubled the RAM in the process, but I know that the increase in RAM had nothing to do with the better scores. I never tested the difference between 4GB and 8GB myself.
