Anybody notice the big jump in latency going to tri-channel? Around 15% worse latency

If I understand correctly, we should all notice the difference between dual and triple channel, but it's very likely that if we use non-multicore applications that the difference will be very small. The bandwidth that is added because of the extra channel is to provide enough bandwidth to fully cover the 8 threads, but is 'overkill' when using in single/dual threaded applications.

Now, that only leaves the everest bandwidth problems. As far as I know, the Lavalys Everest program is quite accurate when it comes to calculating the memory bandwidth and latency, but in tests I've seen the difference still is only 500MB/s:




Only two tests actually show the difference between dual and triple channel, which probably is the correct performance scaling.
