Cpu-Z shows my 1333Mhz ram at 532.2Mhz ??

My ddr3 ram should be running at 1333Mhz unless I am mistaken. In the user guide it said the 2 speeds the ram can be at is either 800Mhz (if the ram is 800Mhz) or 1066Mhz (if the ram is 1066Mhz).

I didn't know this and I bought 1333Mhz ram. I'm only running single channel.
So shouldn't my computer slow it down to 1066Mhz or something? (Would it be better to buy 1066Mhz ram and re-sell this 1333Mhz?)

CPU-Z is showing my DRAM frequency at: 532.2Mhz
On top of that it says that my CPU/DRAM ratio is 4:16 (?!!)

I have never ever seen a ratio that horrible. I heard that 1:1 is the best possible ratio, to have both running in absolute sync.

Do I have a serious problem and is my ram running lower than that of the ddr2 standard (800Mhz) or is this 532.2Mhzz something else and my ram and ratio is perfectly fine.

Something tells me that my ram is running at almost 1/3 of it's best though... and I can't change the voltage or ratio options at all via my bios because it's a locked bios that doesn't allow any sort of modding at all.

Please advise me on what to do... something doesn't feel right...

 

533mhz = 1066 DDR

(533mhz/16) * 4 = 133mhz = base clock of a core i series CPU

 

Thanks bro. So it's running at full speed then? Is the ratio ok?

EDIT: Ok so I 'noobed' out for a second there. Thanks heaps for clearing that up. So if memory is 1333Mhz then it's really only 666Mhz or something. I really wish I had have worked that out earlier... that makes memory seem really slow when compared to a CPU then.

 

Edited the above showing what the ratio means.

 

Honestly, don't worry about your memory speed. It will have zero noticeable effect on system performance since memory is the fastest thing on your system. What slows down your system is called the bottleneck and that is usually the HDD or if you game, the GPU. Very rarely is it anything else (unless the obvious low memory error or CPU demanding calculations).

 

memory speed does impact the system performance
in my experience of overclocking over the years
but as said you ram is running ok

 

In overclocking yes, memory can make a difference but other than benchmarks, stock memory will not have any noticeable effect (except in gaming on integrated graphics).
