Increasing memory decreases Windows Experience Index
I recently upgraded my Win 7 64-bit system with the following:
AMD Phenom II 720 ( tri-core) to an AMD FX-4300 ( quad core )
Increase memory from 4 GB Kingston DDR2-800 to 8 GB Kingston DDR3 -1333
Mobo replaced with new ASUS M5A97 R2.0 ( AM3+ socket )
Retained the GeForce GTX 550-TI GPU and Westen Digital Black SATA-6.0 gb/s 500 GB HDD.
When I ran the Windows Experience Index after the upgraded, my CPU index went up ( from 6.7 to 7.3 ), but the memory index went down ( from 7.5 to 7.3 ). I'm puzzled how doubling of RAM, especially with slightly faster DDR3 ) could cause the index to go down. I've checked the RAM with CPUID and it shows running at the correct frequency, timings, voltages, and running in dual channel mode.
Has anyone had the same experience and why would this happen??
