New motherboard: Lower Windows Index, Slower memory timings...
My old MB (Asus P5N32E SLI) recently died on me, and I got a replacement (Gigabyte EP45-UD3L) Anyways I installed everything and loaded the optimized bios settings. Now, I check CPUz and my memory timings are not what I should have. My memory is OCZ XTC Platinum Rev 2 (link) CPUz shows 5-5-5-15 and what is expected is in fact 4-4-4-15. So I went to the Bios, adjusted the memory latencies to 4-4-4-15 and then raised the default voltage (1.8v) to (1.98v). I know the memory voltage is 1.9v-2.1v but i do not know what exact number I should set it to. So I just chose 1.97v.
Also my Windows Experience Index went down. Hard drive used to be 5.8 and now it is 5.7. Memory and CPU used to be well above 6 (cannot remember exact numbers) and are now both 5.7
what is causing all of this?
I do not know what CPUz shows memory voltage as the defaulted 1.8v, Everest correctly shows the adjusted one at 1.98v.

Did you do a fresh install of Windows?
If not there lies the problem.
Really a fresh install of Windows is whats needed? How come?
