So I've bought a pair of OCZ platinum DDR3 PC-10667(1333Mhz) "OCZ3P1333LV4GK" sticks for my new Lynnfiend system, which worked fine once i've bumped up the DRAM v. to 1.65 from the default 1.5
My concern now is that both my motherboard BIOS and cpuID identified my RAM as DDR3 PC-8500(1066Mhz) part, not the advertised PC-10667(1333Mhz) by default, and I had to manually set its frequency to 1333Mhz.
I didn't have to do that when i was testing my other pair of sticks(Corsair XMS3); they reported as 1333Mhz by default as advertised.
I've had no problems since then but is this something that I should be concerned over? Or something that I should request an RMA and replace them for?
Most likely the XMS3 was rated for 1333 at 1.6v or lower, so it had SPD set for that speed and mobo picked it straight away. Those OCZ sticks require 1.65v(which is above the max 1.6v specified by Jedec) to run at that speed so they cannot have SPD set for that speed and thats why you had to set it manually. At least thats how I understand it.
Anyway, just like o1die said above, if it runs fine than theres nothing to worry about.
