G.Skill Trident DDR3-2500 4GB Review
If there is one accusation you cannot level at Sandra it's inconsistency. As a pure test of Memory performance, as opposed to AIDA64 which is also affected by CPU speed, we can see that the G.Skill takes both first and second place, with the drop to CAS8 giving about .5 GB/s improvement over the kit at stock.
Cache and Memory Bandwidth
When everything is combined in the Cache and Memory bandwidth test to give a score across the board of available bandwidth things rapidly change. No longer is the G.Skill pumping out such huge numbers, although at 2400MHz CAS8 it's still ahead of the 2500MHz CAS9 XMP profile.
wPrime, with its plethora of calculations (up to 1 billion) can be affected greatly by the CPU speed as well as the memory capabilities. Due to slight variances in bus speeds to attain the various RAM speeds for reviews, although all tests had the CPU in the 3.7GHz range you need to be aware that there are a dozen or so MHz here and there difference.
Nonetheless the drop to CAS8 has the desired affect just putting the G.Skill in first place, although the real differences are so slight as to be meaningless..
