Replacing Everest in our labs is AIDA64. This new testing suite is from the core development team from Lavalys and continues that tradition. The guys have thrown in better support for multithreaded CPUs as well as full 64 bit support. We use this to test memory and HDDs for now, but may find ourselves opening this up to other areas of the motherboard.
Of course, when overclocking Disk Performance doesn't vary, which isn't a surprise. What's amazing, though, is the amount of performance that's on offer from this 120GB RAID 0 setup. Random write speed of over 400 MB/s is extremely impressive.
While we don't increase the memory speed, we can indeed see performance does sky rocket when we overclock thanks to the overall extra bandwidth on offer from the CPU being clocked so high.
