Re: [memory] PC3-10700 (667 MHz) ram? said by FizzyMyNizzy:said by matt5:http://www.rampedia.com/index.php/define-ddr
Um the what?
what is DDR - Double Data Rate is a data rate that is twice the clock rate. Data is strobed (during a read or write operation) on both the rising-edge and falling-edge of the clock.
»en.wikipedia.org/wiki/DDR_RAM
Double data rate synchronous dynamic random-access memory (DDR SDRAM)
So what am I wrong about? DDR... double data rate... aka... what cpu-z shows x 2 for the speed.
» en.wikipedia.org/wiki/Multi-chan···itecture quote:
Dual-channel-enabled memory controllers utilize two 64-bit data channels. Dual channel should not be confused with double data rate (DDR), in which each memory module is accessed twice per clock. The two technologies are independent of each other and many motherboards use both, by using DDR memory in a dual channel configuration.
Yep you got confuse.  Actually, 'dual channel' is a chipset feature. Really has no bearing on the actual memory modules. I'm going to have to side with Matt5 here. If you see memory sold in matched pairs so you can utilize 'dual channel', it's nothing more than a marketing ploy.
Look at the attached pic of my ram. I have 1600mhz ram, which will read as 800mhz through CPU-z. Because I have a slight overclock on the ram, it'll reflect that 'as shown'. |

| Having reread my last post I want to clarify something I said that was inaccurate or can be misinterpreted.
"which gives the bios the timings at which the memory can be run."
I should say it gives the jedec standard timings of the module. It doesn't mean that the ram cannot be run at other timings by humans fiddling with the bios settings. |

1 edit | Ya pretty much, first two pics are TMI, third is what matters (I explained it) and aida again is TMI but aida even says ddr3-1333 (667) 665.2 is close enough, clocks are never perfect.
like asdf... said the SPD info is so you can put ram into the system, and the system can set the ram to something that will work, really as I said, it is TMI for the average user.
If you are worried the system is not working correctly or is as you ordered, it looks to be fine.
Now I see after all this TMI of info here... you want to buy more ram, you can buy anything (almost) and it will work, 1800mhz ram (for example) will downclock to 1333 to match yours.
So you want
DDR2 DDR3 (thanks Smoove910  )
1333 or more
99924 or LOWER
1.5 or LESS (not more)
However 8 gigs is alot of ram for the average person and you said you have a SB CPU that should support 24 32 gigs of ram not 16 (that was 1156 forgot the code name).
If you want to buy more ram, 1333 @ 99924 1.5V or faster is what you want. Do not go over 1.5volt for ram. But I will say maybe run by us why you want to add more as I said, 8 gigs is good for the *average* user (I have 16 myself so I understand the want to get more) |
