Core I5 DDR2 Ram only?

[ray liotta]

Is that true? Ive read a few places that will only be DDR2 Ram compatible. Seems abit stupid if it is, and pointless as DDR3 ram is a lot cheaper now and much better.

 

[gurusan]

no it's not true. I5 is ddr3 only

 

[ray liotta]

Oh thanks, did seem abit odd.

Yup, Core i5 has a dual-channel DDR3 memory controller built in.

Did i read this comment wrong then.....

i5 will be mainstream and i7 is highend. The i7's will be binned higher and have more OC headroom than the i5's. Also, the i5's will use the P55 chipset and will not support triple channel memory

Last part of quote is what made me think it was not DDR3. Probably i just read it wrong. Anyway thanks for confirming load of bull.

 

[reflux]

Yeah, they support DDR3 but only dual channel, not triple chanel like the i7s.

 

[ray liotta]

Dumb question but whats difference between dual & triple channel

Does that mean it only takes 2gig sticks, instead of 3gig like I7?

So if i wanted 6gb of ram, i would need 3 2gb ram sticks for a I5, But for I7 i could just get 2 3gig sticks.

Is that it

Correct You get a huge amount more memory bandwidth with triple channel.

Triple Channel would be 3 x 2Gb Sticks

Dual Channel would be 4 or 8Gb for Dual Channel. Of course could do 2 x 2Gb and 2 x 1Gb sticks to get 6Gb. This however would be 4 sticks not 3.

Good luck trying to find a 3Gb Stick.
