i7 - Using Dual channel memory

[craige4u]

I wanted to ask if i can use 2x2GB Sticks (Dual-Channel) on i7 platform without any problem.... ??

Also, what is the Max.Volt Ram is supported by i7 ?

no problems just lower bandwidth - you get 50% boost over the best core 2 ddr3 dual core

1 stick =10k mem bandwidth (same as top ddr3 1600mhz 7-7-6 ddr3 dual channel)
2=15-17k
3=25k

max voltage = max voltage of the cpu = 1.65v

mem controller is built in so it has the same constrants - this is interesting thing about overclocking.

if intel says the max cpu voltage is 1.45 and the max mem voltage is 1.65 should they not be equal? so i am guessing the true max cpu voltage is 1.65?

the triple channel kits are 1.5-1.65v -

1.5 = about the lowest voltage for ddr3 or its slow slow
1.65 = max for the cpu mem controller

By the way the X58 motherboards are tripple channel, which means you benefit greatly with 3 sticks instead of 2. I think you mean 10m instead of 10k.

let me explain again, less cryptic

1 stick of ddr3 in an x58 mobo at 1.65v and 9-9-9 equals = 2 sticks of ddr3 1600 at 7-7-6 at 1.9-1.95v = 10k mem bandwidth

its hard to get 9500-11,000 with ddr3 in prex-58 mobos. in fact most are 8500-9000 mb/s are good!

i sell highend stuff and built both

2 (two) sticks of ddr3 in x58 gives you 15-20k or 50-100% boost of the memory bandwidth of a ddr3 pre-x58 system at optimal settings of 9-9-9 timings at 1600mhz with x58 at less then 1.65v

3 (triple channal - you need to stick them in the right channels) sticks give 20-25k or 200- 250% more, this can be increased to 300% but you might burn up your mobo, x that you will burn it up with 8-8-8 or 7-7-7 with 1.75-1.95v at 1600mhz

some of the above is based on what i read and some on actual systems i built or designed and had built.

Ive seen another that says much the same thing... but cant find it.... Seems if Triple is costing you alot more dosh then its probably not worth it.

Triple channel seems...well, worthless going by just that review on Chook's link.
