Is CAS 8 the new CAS 7?
We’ll start off with Super Pi to check frequency scaling. We set a memory voltage ceiling of 1.85V, which we think is more than most users will ever push into their Hyper based modules for benching. For 24/7 use, we do not suggest more than 1.72V based on conversations with the memory suppliers, actually less is more in this case. The Corsair modules offer just slightly better voltage/frequency scaling in the Super Pi results. We attribute most of the differences here to the variances in the kits we received. The original Corsair kit actually generated slightly lower results when it came to maximum memory clocks. Our first Blade kit was marginally better when it came to voltages at like settings. The kits tie where the CPU is the limiting factor once we are over 2300MHz with CAS 8-9-8 timings. Peak gains when using a higher memory bandwidth are certainly apparent between CAS 6 and CAS 7. With the Uncore multiplier at 16X, CAS 6 on the 2:8 memory ratio loses around 10 seconds to CAS 7 r
