[memory] PC3-10700 (667 MHz) ram?

cpuz says it is running 1333 DDR DOUBLE data rate.... 665x2 = ~ 1333

You can not have tri channel with out 3 sticks, and 1155 does not support tri, 1366 did, and 2011 is quad.

This is what you are using: »www.superbiiz.com/detail.php?p=D···f645fcfd

Yea, your mobo will support it.

BUT one thing we need to know before you start buying it.. Are you using 64bit windows or 32bit windows? If you have 64bit windows you are 100% fine. Everything should work.

Thank you both for the information. I am still a bit confused? Is my ram 1333 (10600) or something else? I was wanting to look up ram from newegg. Just not sure exactly what to look for spec wise.

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.

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.

Um not, the OP asked about the speed being different in CPU-z than the rated 1333, that is because of it being DDR ram.

Also the OP asked about channels, 1155 (ops socket) does not support tri channel only dual, however as you JUST posted... that has no bearing on the clock speed (DDR).

So no, I am not confused, tri channel ram is not 1333 / 3 for a CPU-z number of 444mhz. tri channel ram still shows up as 665mhz. Now if you can show me it NOT then fine, I'm wrong... I will admit, never was hands on with a 1366 rig (never could justify the cost of one to anyone)

OP has two distinct questions, one is because of the ram type being DDR, (the clock speed) the other is the tag of "dual channel" the reason for this is socket 1155 does not run tri, ONLY 1366 (desktop market) ran tri, and the new 2011 socket runs quad.

I will let you figure it out what you type wrong.

Any way, Happy Holidays.

Indeed, same to you!

Yep you got confuse.

reply to KoRnGtL15
You have 1333 ram. I think what is confusing you is the spd tab, which is giving you information about the serial presence detect information on the dimms, which gives the bios the timings at which the memory can be run. It does not give you information about what your memory is actually running at. For that you need to look at the memory tab. Your memory tab shows memory running at 665 which is normal because ddr3 is double pumped(or double data rate) so it is stated as twice the actual frequency or 665x2 which isn't quite 1333 but that is fine there is nothing wrong(they often read like that with slight errors).

On the second issue sandy bridge is dual channel, not triple channel, so there is nothing wrong there either.

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.

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)

Thanks for the correction! was late lol, /facedesk.
